     Define an Ageing Aircraft

An operational aircraft approaching the end of
its design life assumptions
          The Big Question

Does Australia have an ageing aircraft
The Big Answer

We don’t know!
Ageing Aircraft Management Plan

         AAMP Background

CASA initiative in response to Government
Aviation White Paper on need to increase
focus on Australia’s ageing aircraft fleet

AAMP Approved by CASA Strategic Priorities
Committee 25 Feb 2010
      Australian Situation (2005)
The age of the Australian aircraft fleet is increasing:

   Single and multi-engined fixed wing average age 30 years*

   Multi-engine piston aircraft category, over 97% are older
   than the typical 20 year design life*

   Percentage of multi-engine piston aircraft over 40 years has
   increased from 2% in 1995 to 7% in 2005*

   Increased use of older jet aircraft in regional areas (mining
                                * ATSB Report B20050205 – “How Old is Too Old?”
Consider the...VW Beetle
         Ageing Car Analogy

Volkswagen Beetle:
  Designed and first produced in the late 1930’s
  Production ceased Australia in mid 1970’s
  Examples seen on Australian roads could be
  anywhere between 35 – 70 years old
  Cheap to buy
  Increasingly expensive to maintain
  Crashworthiness (Certification) standards
  significantly inferior to that of today
           Ageing Car Analogy

As a percentage of total vehicles, there are relatively
few VW Beetles, Kombis, Chrysler Chargers, EH
Holdens, Datsun 120Ys etc. on the road today

By comparison – Australian skies have a higher
percentage of aircraft that could be considered the
flying equivalent of the cars mentioned above, with a
significant percentage still doing commercial work
             Scope of the AAMP

Effects of ageing aircraft fleets is not fully quantified
or understood
AAMP scope to consider the following aspects:
   Reliability/Availability/Maintainability (RAM)
At what point does the increase in the age of an
aircraft result in unacceptable consequences?
           AAMP Big Picture

AAMP is a CASA project planned to run
in 3 Stages:
  Stage 1 – Scope the magnitude of the ageing
  aircraft issue & recommend risk mitigation
  strategies to CASA management as required
  Stage 2 – CASA Implementation of Stage 1
  Stage 3 – On-going yearly review of effectiveness
  of implementation strategies
              AAMP Focus

Structural fatigue

Wiring systems
Mechanical systems

Maintenance programs
         Existing Regulations

CAR 38 – Part 4A Maintenance
  CASA may give directions relating to the
  maintenance of Australian aircraft for the purposes
  of ensuring safety of air navigation
  CASA may direct the holder of the certificate of
  registration for an aircraft for which there is an
  approved system of make...a
  change to the system that will correct a specified
  deficiency in the system
      AAMP Strategy – Stage 1

AAMP Project is planned to:
  Take six months
  Involve extensive industry consultation
  Make use of external consultants
  Scientific application of risk management concepts
  Identify target aircraft/fleets/market segments
  Prioritise these target aircraft/fleets/segments
  Recommend risk/consequence mitigation
  strategies to highest risk elements
         Industry Consultation

Industry representative bodies
CASA specialists
Industry specialists
Government Agencies
Maintenance organisations
Engineering organisations
Insurance representative
Specialist military advice
     AAMP Timeline – Stage 1

AAMP Stage 1 results will be presented to CASA
Senior Management in December 2010 for

CASA Senior Management will decide scope and
magnitude of any Stage 2 implementation

Magnitude of Stage 3 on-going support dependant on
scope of Stage 2
      AAMP Strategy – Stage 2

Potential considerations for Stage 2 may include
CASA reviews of:
  Systems of Maintenance
  Categories of Operation
  Airworthiness Directives
  Supplemental Inspection Documents (SIDs)
  Supplemental Inspection Program (SIPs)
  Training & Education
     Desired Outcome of AAMP

Develop an ageing aircraft policy

Identify critical ageing aircraft issues

Minimise effects of ageing aircraft issues on
Australian travelling public

Assist in developing pro-active regulations and
advisory material
Safe Roads Skies for All
