SO2 ORAL BOARD RAP 2 Flashcards
What are the levels of maintenance?
Forward: REACTIVE, Sqns
Forward Support: Bays
Depth: Planned/programmed
Explain types of Forward Maint
Corrective
E.g. IRAN: Inspect and Repair As Necessary
Preventative:
Servicing
Scheduled
Condition Based
What are the types of Authorisations?
- Generic: Trade and Rank based
- Nominated: MAMP Ch2.1 P2.1 Operational/maint Necessity
- Local: From AESOs/AEROs for tasks not in MAMP
What are Eng Auths
Engineering Authorisations are the legal document giving individuals responsibility and permission to do work.
EXPAND:
Recognise competence
Generic auths given from MAMP Ch0.6 / AP100B
What types of Servicing are there?
AF/BFs 28 days Condition Based: - NDT - Magplugs
What are the abnormal operating conditions?
And how would these change maintenance?
Hot Cold Humid Salty Sandy/dusty Not being flown?
Define Failure
Maximum degradation of performance of a component
No longer performs its function to a set standard.
What are the failure modes?
Corrosion Cracking (stress fracture) Fatigue Overload Mechanical Wear ANYTHING THAT DEGRADES AN AIRCRAFT
Found in Master Maintenance Schedule
What happens if you lose an Engineering Record Card?
Quarantine item, talk to Lvl J, MilCAM and TAA/DT.
TAA can decide if it will be used and eventually another ERC can be issued with duplicate stats of fleet leader.
What are the latitudes of component life and why do we have them?
Informs the MMO what type of components can be predicted or deferred with which authorisations.
Cannot be done at Stn level:
Fatigue
Provisional
Explosive
What are the pros & cons of deferment?
Pros:
- use it for longer with less work?
- Save money
- “maintain operation capability”
Cons:
- penalty maintenance
- risk to life
What are the pros & cons of anticipating maintenance?
Pros:
- Get work done that needs to be done later, could be while have spare workforce or before going on op/ex
Cons:
- Do work early so lose that many hours of use out of component before buying a new one or doing maintenance work on it
What is Part 145?
European Standard of Maintenance organisation:
Think Red tractor on your milk
What is an AMO?
Approved Maintenance Organisation.
Approved by the MAA MAOS (maintenance approved organisation scheme)
use Part 145 as their set of standards for proof of quality work
They submit a MOE to prove they good
What is an MMO?
Military Maintenance Organisation
What would a potential AMO need to give to the MAOS?
MOE
Maintenance Organisation Exposition
Proof of good work and practices e.g. supervision and quality
Signed by the CEO
What is contingency Maint? (Expedient Repair)
In Operational or Combat conditions: ODH may hold the risk of contingency maintenance that is the bare minimum work required to make an aircraft airworthy
What are the QRs that relate to Engineering?
QR 639: MilCAM
640: OC Eng/ Principal Eng
641: Eng Mgrs
642: producers and supervisors
QR 640
Principal Engineer
Advice Management of resources Ensuring standards and practices Compliance with orders Personnel Procedures Safety
When and How can you not follow an MP
Exemption
Waiver
Alternative Acceptable means of compliance
Basically with a form of some kind from the TAA, you can.
What is an ISTA and what is contained?
Instructions for Sustaining Type Airworthiness. Major part of the ADS
Topics:
include Maintenance manual, mod instructions, SI(T)s, schedules, repair, weapon loading, diagrams, ground handling
What is an ADS and what is contained?
Aircraft Document Set
Aircrew publications
ISTA
Release to service.
What is the ASSC
Air System Safety Case
Structured argument with proof and evidence that states an air system is safe to operate.
Owned by the (SRO) Senior Responsible Owner (while operating is the ODH)
SOIU, Military Type Certification, proof of hours without fuking up
Part of the ASMS
Explicitly addresses HF
What are ADH responsibilites?
Manage Air Safety via ASMS They are SQEP persons Ensure RtL is ALARP and tolerable Personal duty to protect life and reduce risk They are held responsible
DDH low-med
ODH med-high
SDH high-VHigh
What are the 4 pillars of AW
CRIS
Competence
Recognised Standards
Independence
Safety Management System
Air Safety Principles
Leadership
Independence
People
Simplicity
What are the MAA Assurance Principles
(RMIPOF) Risk Based Assurance Minimal Regulatory Burden Independence Proportionate sanctions regime Optimisation Feedback
Continuing Airworthiness
Maintaining AW of individual aircraft, how that one tail number is in a “state for safe operation”
Type Airworthiness
Maintaining AW of a fleet of aircraft through life,
including the upkeep of design and data.
What is Part 145
A set of EASA standards that AMOs must stick to, in order to become or stay as AMOs.
Like to think of them as like the red tractor symbol on milk.
Explain the Risk to Equipment Chain? (DE&S)
DE&S CEO
DG Air
OCD (Operating Centre Director) holding a group of LoAA
TAA/TAM Single LoAA
Eng Authorities (e.g. Landing gear Eng Auth)
