Intro to Maintenance

Typical life of today's aircraft

• 5yrs

• 10yrs

• less than 20yrs

• more than 25 yrs

Can a base maintenance Task be performed in a line maintenance environment?

• never

• always

• if the environmental conditions allow the safe performance of the task and subject to the A/W authority authorization

The business generated by the aircraft maintenance today is

• less important than a/c sale

• as important as a/c sale

• negligible

• not interesting the aircraft manufacturer

When operating the aircraft, what is the airlines’ main goal

• minimize maintenance cost

• optimize operational reliability of a/c

• an optimized a/c availability and reliability for revenues at reasonable cost

3 strategies to minimize in-service interruptions and delays

• Line maintenace

• LRU

• MMEL

• Base maintenance

• Redundancy

items shall be ensured to get cert to perform maintenance according to EASA part 145?

• Infrastructure and Tools

• Personnel and Documentation

• Hangar and Training center

• Spares and Organization

Objective of Maintainability Analysis

• To identify and overcome any shortcomings in Aircraft Design that would impact
  Maintainability objectives and performance
  

• To identify all maintenance tasks and intervals
  

• To identify Safety issues and candidate maintenance requirements
  

• To reduce future maintenance costs
  

Q10) Maintainability Analysis are performed (1pt):

• Only during aircraft development ; when the aircraft is operated, it is too late to change
  the design
  

• Only during the in-service life of the aircraft when airlines identify some trouble with the
  maintenance tasks
  

• Both during development (initial design) and in-service life (design changes)
  

Where difficult maintenance situations are shown to exist:

• The DMU (Digital Mock Up) with incorporation of a Human Simulation (Manikin) will be
  used to demonstrate the difficulty that has been highlighted.
  

• Prototypes will be manufactured on all parts to perform realistic check
  

Which of the following elements IS NOT addressed by the maintainability analyses

• Structures

• systems

• systems installation

• manufacturing tools
