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

What is a CAMO
Continuing Airworthiness Management Organisation
Led by the MilCAM (Military Cont AW Manager)
Responsible for the big picture view of individual tail numbers (small overlap with TAA) ensure through life responsibility for aircraft.
Covered by EASA part M
They have 9 tasks!
9 Key Tasks of a CAMO
1) Develop & control Maintenance Programe (AMP)
2) Co-ordinate scheduled maintenance, apply SI(T)s & replace life-limited parts
3) Ensure quality of maintenance
4) Ensure all SI(T)s are applied
5) Ensure MMOs/AMOs manage faults correctly
6) Ensure weight & moment
7) Manage & archive all CAw records & the operator’s technical log
8) Manage embodiment of mods & repairs
9) Manage AW occurrence reports & follow up activity

0) Organisation
1) CAw Procedures
2) QS
3) Contracted maint
4) Mil AR procedures
Signed by the DDH
Each CAMO has their own CAME, detailing procedures, means and methods the CAMO will follow to ensure their work. Also includes: - List of Air Systems by tail no - General Organisation of the CAMO - CAw procedures - Quality System - Contracted Maintenance - Mil AR proceudres
Who is responsible for the CAMO?
MilCAM - Military Continuing Airworthiness Manager
Retains responsibility for all taskss.
Has a documented agreement of delegation (ICD) INTERFACE CONTROL DOCUMENT
DDH
CAMI?
CAM Instructions.
Temporary instructions in lieu of appropriate TI.
E.g. they will order an inspection of a number of aircraft for a suspected fault, passing on info to DT.
THEY ARE NOT INSTEAD OF SI(T)
CANNOT BREAK ADS rules
What is the MilAR(MAR)
Military Airworthiness Review
An annual review (or Baseline for BMAR) of A/C and records in order to validate AW.
“MOT”
Gives a MARC(ertificate) MOD Form 710
“DDH/AM(MF) shall ensure that the air system is not flown without a valid MARC”
Who carries out a MAR and how?
AR Team, who work alongside CAMO
A surveyor must have 10 years in CAw, 5 Years at super
(civvi equivalent EASA Cat B/C/ Form 4)
How:
- Records review
- Physical review
- Categorisation: Major (AW implication) Minor (unlikely AW) or Observation
3 types AW, Eng, Husbandry
- Rect of findings (corrective action plan)
- MAR report
- Issue MARC
What is an ICD
Interface Control Document
Delegates CAMO tasks to other organisations that do the role. E.g. Eng Records
Explain the CAMO QMS
CAMO Quality Management is the QMS of the CAMO. (nice job josh)
They are usually a WO who has direct access to the DDH.
What are SI(T)s?
Special Instructions (Technical) Temporary instructions issued by the TAA to authorise remedial action to correct a fault or potential fault that can impair the safety, serviceability, or operational capability of an air system.
Who develops/promulagates/manages SI(T)s?
TAA or commodity CE.
Written by the DT
Where are SI(T)s retained?
Topic 2 of ADS
And ERCs/logs cards
What types of SI(T) are there?
UTI - SI(T)s due within 14 days or 25 flying hours
RTI - all others
When are SI(T)s withdrawn?
When there’s a superseding SI(T)
When further application is not required
over-riding publication or design change

What is an RTS and what things are similar?
Release to service. Part of an ADS defines the limits of the air system. Includes the SOIU
Deviations/similar:
Cleared with limited Evidence (CLE) things that are probably safe but you don’t have evidence. Such as new weapons being carried onboard or things that are safe on other A/c. 5 years max!
Op Emergency Clearance: OEC. Held by ODH, operational requirements E.g. Marines on an Apache
Mil Permit to Fly: Pre release to service.
Explain the MACP
Mil Air System Certification Process.
Demonstrating a new air system or modified air system is still airworthy.
IEADRM
Identify Evaluate Agree Demonstrate Review Monitor
Explain Preventative Maintenance?
Aims to prevent faults before they occur rather than IRAN.
Servicing: Check/replenish consumables. e.g. BF/AF
Scheduled: every x hours or cycles these happen. E.g. Minor/Major. Can be OOP
Condition-based: as a result of findings from monitoring: Magplugs or NDT
Explain Corrective Maintenance
IRAN - Inspect and Repair As Necessary
Repairing whats needed to an airworthy standard, rather than restoring to “as new”
Who externally ensures quality of the CAMO?
MMA will audit the CAMO
CAMO QMS will do internally
Talk about CAMO non-compliance.
If non compliant:
Level 1: significant non-compliance w/ serious Air Safety Hazards
Level 2: non-compliance - poss AS Hazard
