CHAPTER 11 – RELIABILITY DATA COLLECTION/EXCHANGE

OVERVIEW
Currently, reliability data is being collected by virtually every aircraft operator as well as airframe, engine
and component manufacturer in the world. Each day, individual companies collect and analyze thousands
of pieces of vital information regarding aircraft components, operations and maintenance in an effort to
further enhance aircraft reliability. This process, while successful within individual companies, is not
properly structured for the collection and exchange of aircraft reliability data between companies.

To date a variety of collection methods, unique to individual companies, make any attempt to exchange
data or measure reliability across the industry time-consuming, costly and subject to error. The
development and implementation of standard record formats for collecting and exchanging aircraft
reliability data will enable the industry to collect, measure and exchange this information in a consistent
format – ultimately improving efficiency and reducing both costs and errors.



PURPOSE
The purpose of this chapter is to provide a set of standardized record formats for collecting and
exchanging aircraft reliability data.



GENERAL USE OF RELIABILITY DATA
There are many reasons for collecting/exchanging and analyzing aircraft reliability data.

One reason is for understanding in-service airplane and component reliability performance and to quickly
identify problems so that root cause analyses can be performed for problem identification and resolution.
An outcome of this type of analysis may uncover an operator’s training, logistics and/or operations
problems being the cause of an apparent reliability issues as well as being caused by the aircraft or
components.

In-service reliability data is often used by manufacturers to compare design-phase predictions to the in-
service actuals to assess the accuracy and validity of the analyses performed during design.

Other uses of in-service reliability data:

     Determine if certain problem areas are unique to an operator or if others are experiencing the same
      problems.

     Determine if the Mean Time Between Unscheduled Removals or No Fault Found rate one operator is
      experiencing is better or worse than the industry norm.

     Determine which modification has a better payback by comparing removal and failure rates of
      operators incorporating various Service Bulletins/modifications.

     Determine schedule interruption rates.

     Determine aircraft flight hours, flight lengths, number of landing cycles as well as utilization rates.

     Understand shop findings to determine if a removal confirms the reason for removal.

     Determine failure mode rates.



SPEC 2000 Modification Request        Draft chapter 11-Reliability data collection/exchange (5 May 2000)        3
AIRCRAFT RELIABILITY DATA
The data necessary to determine aircraft reliability can be broken into seven categories.


1) Aircraft data. This data contains aircraft configuration, operator and time-of-delivery component part
   numbers and serial numbers.
2) Aircraft general statistics data. This data contains flight hours, landings and revenue departures.
3) Aircraft event data. This data contains significant events such as mechanical dispatch delays,
   cancellations, substitutions, air & ground turnbacks, diversions, incidents, and structural difficulties.
4) Component removal data. This data contains the part number, serial number, manufacturer’s code
   and the reported defect pertaining to each part that was removed from the aircraft during a
   maintenance action.
5) Aircraft logbook data. This data contains information that was written up by pilots, cabin crews and
   maintenance crews concerning aircraft discrepancies. It also includes the corrective actions taken by
   maintenance personnel.

6) Scheduled maintenance/dock maintenance data. This data contains information concerning
   scheduled maintenance performed during inspection intervals as called out in the Maintenance
   Planning Documents.

7) Component Shop repair data. This data contains repair information pertaining to fixing internal
   problems related to a part that was removed or returned to the supplier or to an airline repair shop with
   a reported defect.




SPEC 2000 Modification Request      Draft chapter 11-Reliability data collection/exchange (5 May 2000)         4
Standardized Record Format
The purpose of the Standardized Record Format (SRF) is to provide a standard record layout for
transferring data organized by subject matter. These records will be organized in a computer readable
data file to facilitate data transfer. The essential fields in each record contain enough information to
support the loading of these data into a database.
It is important to remember the difference between the SRF data file and a database. The data file is for
data collection and transfer from one computer (site) to another. The intent of a database is to create an
official repository of collected data, forming a homogenous and seamless set of data structures. The SRF
files do not themselves constitute a database but only serve to collect and transfer data.
The SRF is independent of the media used to contain the data files. Traditionally, customers and
suppliers provided high volume data in individualized file formats on magnetic tape compatible with IBM
mainframes. With desktop computing becoming more powerful, and the availability of good data
compression software, files stored on Compact Discs (CD), are the popular choice for smaller data
samples. In any case, (tape, diskette or CD) the media has to be mailed from one company to another,
introducing the overhead and added expense of postal services.
Thus the SRF facilitates direct electronic exchange of the raw data and is a cost effective and efficient
solution to optimize data exchange.
In summary, the SRF is a standardized collection of data, in a readable format, that allows the data to be
easily shared by any company that wants to be involved in the data exchange process.



Overview of Reliability Data Exchange Between Parties
Although this chapter focuses only on reliability data collection/exchange, these figures have been
included to show the larger picture of reliability data collection and exchange today. Figure 1 depicts the
current reliability data flow within our industry. Currently reliability data is exchanged using several
different means from paper copies to non-standard electronic formats. Figure 2 depicts the proposed
method of reliability data flow using the standardized record formats.

For example, an aircraft event (e.g. a pilot report) may cause an LRU to be removed from the aircraft. For
each LRU removed, an LRU Removal Record is produced. This LRU could then be sent to the shop for
repair, and in that case at least one Shop Finding Record is produced.

Note : The repair can generate several reports. This would be the case where the LRU is sent to the Airline shop. The test localizes
a failed SRU which is sent to the original equipment manufacturer workshop for repair. In this example the airline shop may produce
one Shop Finding Record and the original equipment manufacturer will produce a second Shop Finding Record related to the SRU.
The repair of the SRU may in turn generate Piece Part Records (from 0 to n). There will be one Piece Part Record per replaced or
reworked part.

Standardized Record Formats Contained in this Section

The component or Line Replaceable Unit (LRU) REMOVAL RECORD. This Standardized Record Format
(SRF) is for collecting LRU removal data identified by part number, serial number and Commercial And
Government Entity (CAGE) code as well as the aircraft from which it was removed and the details
surrounding why the LRU needed to be removed. It is to be completed by an aircraft operator or third
party repair facility or whomever is removing the defective or high time component.


The SHOP FINDING RECORD. This SRF is for collecting and exchanging LRU shop repair/teardown
findings. It is to be completed by an aircraft operator’s repair shop, third party repair facility or original
equipment manufacturer for the purpose of detailing the findings associated with an LRU that enters a
shop.

             Key fields will link the LRU Removal Record to the Shop Finding Record.


The PIECE PART RECORD. This SRF is for collecting defective or suspect Shop Replaceable Units
(SRU’s) and other piece parts associated with the shop received LRU. It is to be completed by an aircraft
operator’s repair shop, third party repair facility or original equipment manufacturer for the purpose of
detailing the findings associated with an LRU that enters a shop.

             One field will link the Shop Findings Record to the Piece Part Record.


The AIRCRAFT HOURS AND LANDINGS RECORD. This SRF is for detailing the total flight hours and
total cycles of an operator’s fleet. It is for the purpose of calculating reliability measures such as Mean
Time Between Unscheduled Removals (MTBUR), Mean Time Between Failure (MTBF), etc. It is to be
completed by an aircraft operator using one record per aircraft.


Later in this section the data terms and formats for the LRU Removal Record, Shop Finding Record, Piece
Part Record, and Aircraft Hours and Landings Record will be detailed including the definition of each field
and its length.

Removal/Findings Flow Chart
The following flow chart is intended to illustrate the logic used to categorize components that have been
removed from an aircraft and have undergone a shop investigation.

The Spec 2000 Reliability Working Group has noted that our industry has difficulty with the various
nuances of the terms MTBUR and MTBF. This diagram was developed to define these terms using a flow
diagram approach instead of using words. This flow chart is important when populating the Failure/Fault
Found, Failure/Fault Induced, Failure/Fault Confirms Reason for Removal fields contained in the Shop
Findings Record.

LRU REMOVAL RECORD STRUCTURE
PURPOSE
This Record is for collecting LRU removal data identified by part number, serial number and Commercial
And Government Entity (CAGE) code as well as the aircraft from which it was removed and the details
surrounding why the LRU needed to be removed. It is to be completed by an aircraft operator or third party
repair facility or whomever is removing the defective or high time component.


INPUT CONTENTS AND SEQUENCE
An Lru Removal Record is including up to three types of Segment Identifier Codes (SEG). Only one
occurrence of each type is allowed.
The removed LRU segment (RLS) is mandatory in all data transmission. The Next Higher Assembly
segment (NHS) and Installed LRU segment (ILS) are optional.

1.           Record Type Code (RTC) (/)

                          Always coded "33"

2.           Change Code (CHG) (/)

3.           Supplier Code (SPL) (/)

                          Reporting organization must send its cage code. Code ZZZZZ if the reporting organization
                          has no cage code (transmission of RON - Reporting Organization name - then required) or
                          if the reporting organization is the Operator (RON not required in this case).

4.           Operator Code (OPR) (/)

                          Use 3 digit ICAO code only. Code ZZZZZ if no ICAO code exists (bizjet operator for
                          instance), transmission of name -WHO- is then required.

5.           Aircraft_Model_Code (AMC) (/)

6.           Aircraft Identification Number (AIN) (/)

                          Code ZZZZZ if submitting Aircraft Registration Number- REG- or Operator Aircraft Internal
                          Identifier- OIN- when AIN not sent.
                          However use of AIN (serial number assigned by the aircraft manufacturer) is strongly
                          recommended.

7.           Removal Reason Text (RMT) (/)

8.           Part Removal Date (RED) (/)

PROCEDURES
Several data conditions applicable to various portions of this section are of prime importance to the
methods of transmitting data. The data conditions are broken into the following categories:

● Update Change Codes

●     Multiple Occurrences of a Text Element Identifier (TEI)

●     Data Set Groups

Each of the above data conditions will be explained in detail in the pages that follow.

Each record is variable in length. To illustrate the examples, a record may be represented on several lines
in this document. Therefore realize that a continuation of a record on the next line does NOT depict a
break in the record.

If alpha "O" is encountered in a numeric field, it will be converted to a numeric zero.

If a supplier duplicates a TEI that is only required once, the record will be rejected if the data element is
mandatory. If the duplicated TEI is conditional, only the data element will be rejected except as noted in
the data audit section. This same rejection procedure will be used when multiple occurring TEI's are
applied and the allowable number exceeds the limit.

To establish some of the rules stated in this section it has been assumed that both the sender and the
receiver are maintaining their own data base.

Update Change Codes
Change Codes are transmitted with each record to indicate the type of change being requested. To keep
the change management as simple as possible there are three Change Codes - New, Total Replacement,
and Delete - that are allowed in reliability applications.
The changes are managed at the record level only (not at the segment or data element level).

NEW - CHANGE CODE = N

When establishing a new record, all mandatory data elements must be present. All other conditional data
elements can be added if needed.

TOTAL REPLACEMENT - CHANGE CODE = T

When Change Code T is used, the existing data base record will be replaced in total at the receiver. If the
record does not exist , the record will be added to the data base. All mandatory data elements are required
to do a total replacement. Conditional data elements are included as required.

DELETE - CHANGE CODE = D

A delete is accomplished by providing a Change Code of D. All mandatory data elements are required to
do a delete. All conditional data elements in the existing data base record will be deleted as well.

The following diagram explains the use of the N, D, T values to manage changes to the record.

If the change does not involve a key data element, for instance adding/modifying a conditional data
element or modifying a non key mandatory data element, the revised record is transmitted with a change
code of T.

Update Change Codes (Change Code T)

T -The Change Code of T is used to totally replace a record. Revising an already sent record may be
effected by submitting a complete replacement record, change coded T. This technique simply overlays
the current record on file with the replacement record. If the record does not exist on the central file, the
record will be added to the data base.

When the "T" Change Code is used, all mandatory data elements must be restated.

Multiple Occurrences Of A Text Element Identifier in LRU Removal Record
Only one TEI in LRU Removal Record can have multiple occurrences :

Total Time Text (TTM)

TTM can have up to 6 occurences. Multiple occurrences of the above TEI must appear consecutively in
the record.

When a supplier changes any data with multiple occurrences, all occurrences which should remain on the
receiver Data Base must also be transmitted. The receiver will delete all existing occurrences and insert
the new information transmitted by the sender.


Data Set Groups
Data set groups are a method of collecting groups of information together within a Text Element Identifier
(TEI). There is one data set group which apply to LRU Removal Record :

Total Time Text (TTM)

When a supplier changes any data within the TTM data set group, all sets which should remain on the
Data Base, must also be transmitted. The receiver will delete all existing TTM records and insert the new
information transmitted by the sender.

If the change does not involve a key data element, for instance adding/modifying a conditional data
element or modifying a non key mandatory data element, the revised record is transmitted with a change
code of T.

Update Change Codes (Change Code T)

T -The Change Code of T is used to totally replace a record. Revising an already sent record may be
effected by submitting a complete replacement record, change coded T. This technique simply overlays
the current record on file with the replacement record. If the record does not exist on the central file, the
record will be added to the data base.

When the "T" Change Code is used, all mandatory data elements must be restated.

Multiple Occurrences Of A Text Element Identifier in Shop Findings Record
Only one TEI in Shop Findings Record can have multiple occurrences :

Total Time Text (TTM)

TTM can have up to 6 occurences. Multiple occurrences of the above TEI must appear consecutively in
the record.

When a supplier changes any data with multiple occurrences, all occurrences which should remain on the
receiver Data Base must also be transmitted. The receiver will delete all existing occurrences and insert
the new information transmitted by the sender.


Data Set Groups
Data set groups are a method of collecting groups of information together within a Text Element Identifier
(TEI). There are two data set groups which apply to Shop Findings Record :

Shop Finding Text (FIT)

Total Time Text (TTM)

When a supplier changes any data within the FIT, and TTM data set groups, all sets which should remain
on the Data Base, must also be transmitted. The receiver will delete all existing FIT, or TTM records and
insert the new information transmitted by the sender.

Create Aircraft Hours & Landings Record-Update Change Codes (Change Code N)
N - To establish a new aircraft hours and landings record, the Change Code of N is applied. The minimum
data elements required to establish a record are:

Record Type Code

Change Code

Supplier Code

Operator Code

Aircraft_Model_Code

Aircraft Identification Number

Report Month

Aircraft Cumulative Total Flight Hours

Aircraft Cumulative Total Cycles

Note : The specification allows some of the above mandatory elements to be coded as ZZZZZ when not
transmitted. In this case it is required to send the corresponding conditional data element when the record
is created. If this requirement is not met, the record is rejected (refer to data audit section further in this
chapter).

When revising a LRU Removal Record two situations may occur.

If the change involves one of the key element of the record, the existing record must first be deleted (using
change code D), then the modified record is submitted as a new record (change coded N).

If the change does not involve a key data element, for instance adding/modifying a conditional data
element or modifying a non key mandatory data element, the revised record is transmitted with a change
code of T.

Update Change Codes (Change Code T)

T -The Change Code of T is used to totally replace a record. Revising an already sent record may be
effected by submitting a complete replacement record, change coded T. This technique simply overlays
the current record on file with the replacement record. If the record does not exist on the central file, the
record will be added to the data base.

When the "T" Change Code is used, all mandatory data elements must be restated.

SUPPORTING TECHNICAL INFORMATION

Coding of Removal Type Code (TYC)
This data element is the key and direct entry for computation of reliability values (MTBR, MTBUR, and then
various MTBFs). Referring to figure 4 (Removals/Findings Flow Chart) earlier in this chapter the following
diagram (figure 6) specifies how Removal Type Code (TYC) must be coded in each situation that may
occur. Strict adherence to this diagram is required to allow an accurate computation.

                                 was due to either hardware or software.

For position 1 the use of dash ("-") is not allowed.

Referring to figure 4 (Removals/Findings Flow Chart) earlier in this chapter the following diagram (figure 7)
specifies how positions 1, 2, and 3 of FIT must be coded in each situation that may occur. Strict adherence
to this diagram is required to allow an accurate computation of reliability (MTBF(J), MTBF(N), MTBF(C)).

The ability of the repair shop to populate all positions above depends upon the results of tests and
analyses performed by the repair shop, but it also heavily depends upon information that the shop is
provided with. This information is transmitted through LRU Removal Record with the main following data
elements : Removal Reason Text (RMT), Maintenance Action Text (MNT), Fault code (FLT), Aircraft
Message Text (AMT). Although some of these data elements are conditional it is highly recommended to
send them.

Data Audits
Each data field or relationship audit found to be in error as a result of these audit routines should be
identified by the receiver as one of the following:

1.           Rejection of the entire record

2.           Rejection of a conditional segment

3.           Rejection of a conditional TEI

All audited data regardless of audit message should be reported to the supplier in writing as soon as
possible.
An entire record rejection, conditional segment reject, or conditional TEI reject should not be updated in the
receiver's file as applicable.

In order to maintain the integrity of the receiver's data base all audit reports should be returned to the
supplier within ten (10) working days following receipt of the file.

The following lists indicates the audit by record type (i.e. LRU Removal Record, Shop Findings Record,
etc.)


RELIABILITY DATA AUDITS

Note: All data field characteristics, definitions, structure, remarks and audits can be found in the ATA
Common Support Data Dictionary (CSDD). Any exceptions will be indicated in the "Type Audit" column.

The "Action" column indicates the action to be taken in the event of an error condition in order to maintain
compatibility between the user's and transmitter's databases.

SPEC 2000 Modification Request                Draft chapter 11-Reliability data collection/exchange (5 May 2000)                          76
TEI IN-FRONT METHOD

Introduction
The section 1 details the specification of the different records needed for component reliability data
collection based on the traditional Spec2000 method of transmitting data.
This paragraph proposes an alternate method that would allow companies wishing to use common PC
based spreadsheets or database software to still participate to reliability data exchange.
This method uses the exact same data elements as defined by the data dictionary including their Text
Element Identifier (TEI).


The Method
Assuming that a file is being transmitted as an ASCII text file.

1-The first line should define the type of data being transmitted, e.g. one of the following:
LRU Removal Record : /RTC 33/
Shop Findings Record : /RTC 34/
Piece Part Record : /RTC 35/
Aircraft Hours and Landings Record : /RTC 36/

2-The second line should contain a list of the TEI of the parameters being transmitted (leaving out those
optional parameters that have not been opted for) separated by the Spec2000 delimiter (/).
The structure of the records as defined in the relevant paragraphs is entirely applicable.

3-Then following this line would be all the records of the selected type for the month, each record
containing data for one event and contain data for each parameter as specified in the second line in the
same order as the parameters specified, one record per line.

Note: The second line would list the maximum number of parameters intended to be populated by the
supplier of the data. Then in the following data lines, if an optional field has no data for a particular event,
the field could be left blank – which would be captured by having two delimiters following each other (//).

The above file can easily be imported into most common spreadsheets software, and the second line
being a statement of the variable names, would enable the file to be imported into a database software
through an appropriate query.

Example
Figure 8 shows a sample removal file submitted by an operator in ASCII text format. Figure 9 shows what it
would look like if imported into a spreadsheet software.
In this example the transmission includes only the mandatory data elements of the record (refer to LRU
Removal Record Structure section).
