Maintenance Practices Flashcards
Describe the MSG?
Maintenance tasks to maintain reliability, continued airworthiness and safety built into design of aircraft
What is MRB? What does it do
Maintenance review board.
Approved maintenance program before it can be used
Who creates the maintenance responsibilities?
Shared between NAA, Airline and Airline regulator
What does the Certification Maintenance Coordination Committee do?
Assess whether items should be:
- Certificate of Maintenance Requirement (CMR)
- Airworthiness Limit Items (ALI)
- Safety Systems Assessments (SSA)
Who is in the MRB?
NAA, Design Organisation, Manufacturer
What does the MRB do?
Assist design organisation in establishing approved initial maintenance program for the aircraft (MRBD)
What is ISC?
Industry Steering Committee
What does ISC do?
Develop polices and procedures for development of MSG-3 Maintenance requirement
What is MSG-3
Maintenance Steering group.
Using maintenance as a means of restoring safety & reliability back to their inherent design levels through better failure analysis and a continuous airworthiness maintenance program
What are the 6 different ISC Working groups?
WG1 Flight controls, hydraulic WG2 Environment and Int. Systems WG3 Fuel, Power plants and APU WG4 Avionics, Electrics WG5 Airframe Structure WG6 Zonal
What is in MRBD?
Systems inspections and Checks Structural Inspections and Checks Zonal Inspections ALI (Airworthiness Limit items) CMR (Certificate Maintenance requirement) MMEL CDL (Config Deviation List) SIP (Structural Integrity Program CPCP (Corrosion Preventative and Control) STC (Supplementary Type Certificate)
What type of maintenance is servicing?
- OC (On conditioning)
- Replenishment of fluids, lubrication parts, cleaning, checking tyre pressure or fluid levels
What is preventative maintenance?
Carried out with scheduled activities
Aim is to prevent defects
What is corrective maintenance?
Correcting defects or applying MEL
Often unscheduled
With preventative maintenance, what type of checks are minor checks
