					FAA Form 337
  Training
             Welcome!

This class is to provide you with a basic
 understanding of the FAA Form 337.

You will learn the uses of this form and
 information about completing some of
 the blocks.
On the next few slides we will see the
   front and back of the Form 337.
 At the top of the form itself are
 INSTRUCTIONS:

    See FAR 43.9, FAR 43 Appendix
 B, and AC 43.9-1 …for instructions…
 It also states that:
“This report is required by law. Failure
 to report can result in a civil penalty
 for each such violation.”
The current version of FAA Advisory
Circular 43.9-1() provides instructions
for completing FAA Form 337, Major
Repair and Alteration (Airframe,
Powerplant, Propeller, or Appliance).
 FAA Form 337 is used to document
two things, and only two things:


       Major repairs

     Major alterations
This means that you need to know how
 to determine what is a major repair or
  major alteration. That is outside the
   scope of this class (actually, it is a
           class all by itself!).
A comment about documenting major repairs.

 Due to an exception in Part 43, Appendix
 B(b)2, a Repair Station may document a
 Major Repair using a signed copy of the
 work order in lieu of the Form 337.
 So there may be occasions when you
 perform a major repair and don’t issue a
 337. This is based on customer
 preference. We will use either a 337 or the
 work order to document a major repair,
 depending on what the customer wants.
    Appendix B TO PART 43 states:

“Execute FAA Form 337 at least in
duplicate;”
“Give a signed copy of that form to the
aircraft owner;”
“Forward a copy of that form to the FAA
Aircraft Registration Branch in Oklahoma
City, Oklahoma, within 48 hours after the
aircraft,….is approved for return to
service.”
The Duncan Aviation RSGOM states:
 “An original signed FAA Form 337 is
 provided to the aircraft owner or
 operator. A copy shall be sent to the
 FAA in Oklahoma City and a copy is
 stored with the work order.”

Duncan Aviation minimum requirements:
 One original, Two copies.
             Item (Block) 1
States “Aircraft”.
A 337 can only be issued to an aircraft!
Not a component part. Doesn’t make any
difference if you worked on a cabinet,
engine, prop or other appliance. The 337
is for the aircraft the item is installed on.

This affects “send in” or spare
components in a big way. Here’s how….
NOTE:
When a major repair or major
alteration is made to a component
part, items (blocks) 1, 2, and in some
cases 5 will be left blank and the
original and duplicate copies of the
form (337) will remain with the part
until it is installed on an aircraft.
Example
         So let’s understand this.

We can perform a major repair or
alteration to a spare part. We can fill out
all of a 337 (including signing it) except
items 1 and 2. The part can sit in the
warehouse for weeks or months. The
person who installs the part onto an
aircraft fills out items 1 and 2 and then
has 48 hours to forward a copy of the
completed 337 to the FAA after approving
the aircraft for return to service.
             Item (Block) 1
Nationality and registration mark:
 The FAA only accepts 337s for US
 registered (N) aircraft. If you are
 providing a “courtesy” 337 for a
 foreign registered aircraft, don’t bother
 sending a copy to the FAA. They
 won’t take it. The FAA only maintains
 information for US registered aircraft.
         Item (Block) 3


     For FAA Use Only.

Block 3 is used by the FAA for field
             approvals.

           Field what??
Field approval refers to a method of
approving the data for a major repair
or major alteration. When this method
is used by the person completing the
337, all data is submitted to the FAA
for approval. Once the FAA has
approved the data, they will sign in
block 3 showing their approval. This
is commonly referred to as a field
approval.
If you need to use the field approval
   method, here’s a tip:
 Get your data approved before you do
 the job!
 There is nothing quite as discouraging as
 fixing up an airplane in a way you think is
 great, only to have the FAA disagree and
 want it done another way! And that could
 happen if they don’t agree with your data
 on a field approval.
           Item (Block) 6
Conformity Statement!

 When you sign this, you are taking full
 responsibility that you know what was
 done and that it conforms to the data
 and Part 43 maintenance
 requirements!

 At Duncan Aviation, the person signing
       here must be an Inspector
Block 6 asks for the name and address of
the person (agency) who did the work, the
kind of agency (mechanic, repair station,
etc), their certificate number, the date they
finished the work and their signature.
Duncan inspectors sign as agents of
Duncan Aviation. When signing on behalf
of Duncan, we check the box next to
“Certificated Repair Station” and use the
repair station number, not your personal
certificate number.
Notice the statement in box “D”. This is
what you are certifying when you sign.



You are certifying that the repair or
alteration conforms to the description (or
data) shown on the back of the 337 along
with any attachments.
Thus, you are making the conformity
statement for the repair or alteration.
              Item (Block) 7
Approval for Return to Service!

 This is the block where the repair or
 alteration is either Approved for return to
 service, or Rejected for return to service.
 If you’re involved with installing a part that
 has a 337 with it, make sure that item 7 is
 checked Approved!
Where block 6 says the work conforms to
the data, block 7 says it has been
inspected and is approved for return to
service (also called RTS approval)

      (RTS = Return To Service)

Conformity and RTS approval are two
separate steps.
Notice the first line. It says the unit was
 inspected and then gives you the choice
 to declare it “Approved” or “Rejected”


 One of these boxes must be checked!
 (Hopefully “Approved”) But you must
 inspect the work before you know if it can
 be approved. Does this mean you
 personally must go and look at the repair
 or alteration and verify every single
 detail?
                     No.
HOWEVER:
 If you do not personally inspect every
 detail, you absolutely have the
 responsibility to ensure that properly
 authorized Duncan Aviation inspectors
 signed off on their respective portions of
 the job.
 As a repair station, our system allows an
 inspector to review individual squawks stamped
 by other qualified inspectors as a means to
 determine airworthiness.
Once a date is put in block 7, you
started a countdown!
You have 48 hours to get a copy in
the mail to the FAA.

              EXCEPT

for send in items (those 337s will be
 mailed by the person installing the
 item on the aircraft.)
          Item (Block) 8
Description of Work Accomplished

    Sounds self explanatory, right?

 And to some degree, it is. Describe
 the work in sufficient detail that a
 person unfamiliar with the job can
 understand what was done.
Other things that we want to include in the
   Description of Work Accomplished:
The FAA Approved Data that was
 used.
Any change to the Weight and Balance
 data.
ICA (Instructions for Continued
 Airworthiness) information.
Any Flight Manual Supplements.
     Instructions for Continued
            Airworthiness

Generally these usually apply to
major alterations, but some major
repairs may affect the Inspection
Program the aircraft is following!
So, if you have performed a major
alteration, the FAA wants to ensure
the owner/operator has the necessary
knowledge to maintain the “altered
product”.

You must put in some type of
information that tells the operator how
to inspect and maintain this alteration
you just signed off.
          * Thank You *
That completes the training on FAA
Form 337. You now have knowledge
of when this form is used, and how to
review one to ensure all information is
there, and what to do with the
completed form.

If you have any other questions, feel
free to ask any Chief Inspector or
Quality Department Inspector.
