6. Subpart A
SUBPART A - General
Basic scope statement for DASR M
Establishes the measures to be taken to ensure that airworthiness is maintained, including maintenance
Specifies the conditions to be met by organisations involved in continuing airworthiness management

7. Subpart B SUBPART B – Accountability
The Operating Organisation is accountable for the continuing airworthiness of an aircraft
The Operating Organisation shall be a CAMO (Subpart G)
The Operating Organisation shall:
have an internal DASR 145 approval
or contract/task (through a CAMO) an approved 145
Master/slave relationship - CAMO is the master, AMO is the slave
Contains flexibility to contract/task maintenance organisations deemed equivalent to DASR 145
Access requirements for the Authority
Occurrence reporting
Key Differences/Similarities to TAREG System
TAREG has provisions for other than TAREG AMOs to conduct maintenance
Occurrence reporting in DASR is regulated only for conditions that endanger flight safety.
Key Differences/Similarities to TAREG System
TAREG has provisions for other than TAREG AMOs to conduct maintenance
Occurrence reporting in DASR is regulated only for conditions that endanger flight safety. TAREGs arguably require deeper level of reporting - Ref c where AMOs are required to report conditions including those that do not directly endanger flight safety.
M.A.201(g) - Maintenance of military aircraft, and components thereof shall be carried out by a DASR 145, or equivalent 145, AMO. AMC GM
AMC 201(g)
This is a placeholder for AMC that will explain those approvals considered equivalent to DASR 145 and activities to be conducted by a CAMO prior to authorising the conduct of maintenance by a DASR 145 equivalent Approved Maintenance Organisation (where the NMAA has already conducted recognition activities of an NAA or external NMAA). Where the NMAA has not conducted recognition activities of an NAA or external NMAA the AMC will clarify how equivalence should be demonstrated by the CAMO to the satisfaction of the NMAA.
The NMAA expectation is that this clause will cover maintenance organisations operating under the following:
A commercial 145 maintenance organisation under an ICAO based 145 maintenance approval (such as a CASR 145, FAA 145 Repair Station or EASA 145 Approved Maintenance Organisation)
A military or commercial maintenance organisation under an EMAR 145 regulatory framework. Current airworthiness recognition activities within Air and Space Interoperability Council (ASIC) nations (US DoD, CA, NZDF, UKMoD, ADF) are underway to recognise maintenance structures against EMAR 145 principles .
M.A.201(l) - By derogation to paragraph (g) and (h)2, the NMAA may agree to an alternative approach for a maintenance organisation to demonstrate its capability, equivalent to DASR 145, to perform maintenance of military aircraft and components thereof, in lieu of holding a DASR 145 approval
AMC M.A.201(l)
This is a placeholder for AMC that will explain how a CAMO can demonstrate to the NMAA the suitability of a maintenance organisation where compliance with 201(g) is not possible or feasible.
The NMAA expectation is that this clause will cover maintenance organisations in the following scenarios:
A military or commercial maintenance organisation operating under an NMAA construct that is not recognised against an EMAR 145 framework.
A commercial maintenance organisation performing specialised maintenance activities which cannot be conducted under an existing DASR 145 AMO (using sub-contractor provisions in 145.A.75). This scenario only applies when the lead DASR 145 AMO does not have its own expertise to determine that the sub-contractor meets the necessary standards.

8. CAMO Tasks Aircraft Continuing Airworthiness Record System
Accomplishment of Maintenance
Aircraft Maintenance Program
Management of Defects
Airworthiness Review
Pre-Flight Inspection
Reliability Program
Analysis of AMP
CAMO Tasks
Occurrence Reporting
Aircraft Tech Log
Airworthiness Directives
Maintenance Check Flights
Modification, Repair & Inspection
Coordinate scheduled maintenance
Weight & Balance/ Symmetry Checks
From a technical perspective, the CAMO is ‘responsible’ for the continuing airworthiness of the aircraft under its control (serial numbers).
The MTC Holder is accountable for the ‘continued airworthiness’ of the Military Type Certificate for that type of aircraft..
The CAMOs job is to manage the aircraft in such away to ensure it remains:
airworthy (true to the MTC),
fit for task
usage is optimised.

9. DASR M – Continuing Airworthiness Management tasks
Key Differences/Similarities to Current System
DASR M – CAMO responsibility
Current System Equivalent
Aircraft Maintenance Programme (AMP)
– includes error capturing methods
Broadly equivalent to TMP, PSS and AMM
IMIs
Reliability Programme/Analysis of AMP
Changes driven from failure reporting and usage data
Accomplishment of Maintenance
Maintenance contracts, SLA, Maintenance release
Coordinate scheduled maintenance
CAMM2, Maintenance Coordination, Fleet Planning
Mods, repairs and inspections
IA/SR, Fleet Planning, CCB

11. Subpart C – Deferred Defects

12. Subpart G
DASR M – SUBPART G - CONTINUING AIRWORTHINESS MANAGEMENT EXPOSITION (CAME)
Scope of work
Organisation chart showing chains of responsibility
Procedures specifying how CAMO ensures compliance with DASR M
List of approved AMPs
List of all contractors/tasked organisations
Names of all Operating Organisations to which the CAMO provides support
Key Differences/Similarities to TAREG System
CAME will consist of/reference a combination of elements contained in AMO MMP and AEO EMP. It will also detail a number of processes that are currently conducted but not regulated, e.g. fleet planning.

13. DASR M – SUBPART H – CERTIFICATE OF RELEASE TO SERVICE
Subpart H is applicable to DASR 145 equivalent maintenance organisations
DASR 145 AMO CRS issued in accordance with DASR 145
DASR 145 equivalent AMO (M.A.201(g) and (l) clauses) CRS issued in accordance with Subpart H
Aircraft certificate of release to service
Component certificate of release to service
Key Differences/Similarities to TAREG System
CRS is broadly equivalent to maintenance certification under TAREG
Aircraft CRS is broadly equivalent to maintenance release

14. DASR M - SUBPART I – MILITARY AIRWORTHINESS REVIEW CERTIFICATE (MARC)
Aircraft airworthiness review, including a review of the aircraft records and a physical survey of the aircraft
Valid for one year, can be extended twice
Findings
MARC may be issued by a CAMO (with privileges), by airworthiness review staff (approved by the NMAA) or by the NMAA, depending on the situation
Key Differences/Similarities to TAREG System
Airworthiness Reviews are not conducted in TAREG system. The closest comparison is Navy’s annual husbandry checks.

15. CAMO Key Positions
