Maintenance Programm


Maintenance of each aircraft (except parachutes and hang-respectively para glider) shall be organised in accordance with an aircraft maintenance programme.
The aircraft maintenance programme establishes the measures to be taken to ensure that airworthiness of an aircraft is maintained, including maintenance. The aircraft maintenance programme shall contain details of all maintenance to be carried out and shall be subject to periodic reviews and amended accordingly when necessary.

The aircraft maintenance programme must establish compliance with:
  • instructions for continuing airworthiness issued by the holders of the type-certificate, restricted type-certificate, supplemental type-certificate, major repair design approval, ETSO authorization or any other relevant approval, such as
    • Maintenance Review Board Report (MRBR)
    • Maintenance Planning Document (MPD)
    • Operations Manual (wie AMM, EMM, ...)
    • Service Life Limits (LL)
    • Airworthiness Limitations (ALI)
    • additional instructions for continuing airworthiness due to changes/modifications to the aircraft (e.g. STC, EMZ, EB, ...)
    • zusadditional instructions for continuing airworthiness due to repairs
    • technical bulletins (SB, SL,TM, ...)
    • operational requirements (e.g. ETOPS, LOVA, ...)
  • instructions and notices issued by the competent authority, e.g.
    • Airworthiness Directives (AD)
    • National Airworthiness Directives (LTA)
    • Airworthiness Notices (LTH)

IHP Preparation and Approval

Austro Control GmbH provides an optional form for the preparation of an IHP according M.A.302 of Regulation (EU) 1321/2014.

Template Maintenance Programme Part-M

The Maintenance Programm (IHP) and all subsequent revisions must be approved
  • by Austro Control GmbH or
  • by a CAMO / CAO with an indirect approval privilege.

AMP Preparation and Approval

For complex motor-powered aircraft and/or aircraft used in commercial air transport the preparation of an Aircraft Maintenance Programme (AMP) document acc. M.A.302 of Regulation (EU) 1321/2014 is necessary.
Austro Control GmbH provides the following standardised checklists for the preparation of an AMP:
  • The Aircraft Maintenance Programme Checklist provides a guideline for the preparation, content and structure of an Aircraft Maintenance Programme (AMP) and also serves as an “AMP Compliance Checklist” related to Appendix I of AMC M.A.302 and AMC M.B.301 (b) - “Content of the maintenance programme” of Regulation (EU) 1321/2014.
The Aircraft Maintenance Programme Checklist should be enclosed in the AMP whenever the Aircraft Maintenance Programme (AMP) will be directly approved. The “Operator Section” needs to be completed respectively a reason if something is not applicable must be stated.

The specific points and procedures shall be either covered in the AMP (aircraft- or fleet-specific) or in the CAME (across the fleet). Therefore, provide the AMP- and/or CAME-reference number (only the reference to the AMP or CAME is insufficient).
  • The AMP Additional Inspections List contains a summary of all additional requirements from national regulations (such as laws, acts, LTA, LTH, ...) and other EU-specifications (such as Air OPS, CS, SIB, ...)
The AMP additional Inspections List shall as well be provided including the compliance & tracking tool task references and shall be enclosed or attached to the AMP and kept up-to-date. If a listed maintenance measure is not applicable, a reason must be stated.

The Aircraft Maintenance Programme (AMP) and all subsequent revisions must be
  • submitted to Austro Control GmbH for approval or
  • approved by a CAMO / CAO with an appropriate indirect approval privilege.
This is applicable for aircraft registered in Austria; for aircraft which are operated under a 83bis agreement the relevant requirements are outlined in the individual 83bis agreement.

AMP / IHP Indirect Approval

If the continuing airworthiness is managed by an organisation which is approved according
  • Section A Subpart G of Annex I (Part-M) or
  • Annex Vc (Part-CAMO) or
  • Annex Vd (Teil-CAO) (only for IHP)
to Regulation (EU) 1321/2014 (CAMO / CAO) or
  • if a limited contract between the operator and such an organisation acc. M.A.201 (i) (3) is established (only for IHP)
the aircraft maintenance programme and its revisions can be approved through an indirect approval process. This procedure needs to be outlined tin the handbook (CAME / CAE) and needs to be approved by the authority.

(Only applicable when both the aircraft and the CAMO / CAO are under supervision by the same EASA member state)

Annual Review

The aircraft maintenance programme shall be subject to periodic reviews (at least annually) and amended accordingly when necessary. These reviews shall ensure that the programme continues to be valid in light of the operating experience and instructions from the competent authority whilst taking into account new and/or modified maintenance instructions promulgated by the type certificate and supplementary type certificate holders and any other organisation that publishes such data in accordance with Annex I (Part-21) to Regulation (EU) 748/2012.
  • IHP: the annual review shall be confirmed and enclosed to the aircraft records after completion
  • AMP shall be reviewed according to the following (and if necessary adapted) list and enclosed in the CAME including the relevant procedures: Annual Review Checklist

Reliability Programme

For complex motor-powered aircraft, when the maintenance programme is based on maintenance steering group logic (MSG-3) or on condition monitoring, the aircraft maintenance programme shall include a reliability programme.
  • The purpose of a reliability programme is to ensure that the aircraft maintenance programme tasks are effective, and their periodicity is adequate.
  • A reliability programme provides an appropriate means of monitoring the effectiveness of the maintenance programme.
Detailed procedures about the reliability programmes (normal and simplified) shall be included across the fleet into the CAME.

A reliability compliance according to Appendix I to AMC M.A.302 and AMC M.B.301 (b) (Content of the maintenance programme), point 6 shall be demonstrated to Austro Control GmbH.

Simplified Reliability Programme

For small fleets (< 6 LFZ aircraft of the same type) a simplified reliability-monitoring-programme - see also LTH 60A - may be applied and shall be included in the CAME cross-fleet.

For all aircraft which are
  • not within the scope of Part-M and
  • not within the scope of LTH 43C icw § 48 ZLLV 2010 (Annex I-A/C)
the Maintenance Programme (IHP) and all subsequent changes shall in accordance with ML.A.302 (b) either be
  • declared by the owner where the continuing airworthiness of the aircraft is not managed by a CAMO or CAO; or
  • approved by the CAMO or CAO responsible for managing the continuing airworthiness of the aircraft.
This means that Austro Control GmbH will not approve any maintenance programmes according Part-ML and will also not accept applications for Part-ML maintenance programmes.
 
The responsibility for the maintenance programme lies with
  • the owner or operator who is responsible for managing the continuing airworthiness or
  • the CAMO or CAO with which a contract for managing the continunng airworthiness has been established.
 
Templates for the preparation of a Part-ML maintenance programme can be found in AMC2 to ML.A.302 in the EASA Acceptable Means of Compliance (AMC) and Guidance Material (GM) for Annex Vb (Part-ML) to Regulation (EU) 1321/2014. Austro Control GmbH provides a fillable template for a Part-ML maintenance programme:

Template Maintenance Programme Part-ML

Maintenance programmes approved prior to the inception of Part-ML remain valid. All changes or deviations to the maintenance programme require a re-issue (approval or declaration) of the maintenance programme acc. Part-ML.

Note:
Also one-time deviations to a Part-ML maintenance programme must either be approved by the responsible CAMO / CAO or declared by the owner / operator.
