Sofema Aviation Services (SAS) www.sassofia.com considers the process to develop the scope of activities to be undertaken by the Maintenance Control Centre (MCC)
Introduction
The MCC sits between the Operations Control Centre (OCC) and Aircraft Maintenance Organisation (AMO) including:
- Base Maintenance
- Line Maintenance
- Outstation Maintenance
The MCC essentially provides a range of services to meet the operators objective and at the same time satisfying associated regulatory requirements. (note – there are not direct regulatory requirements – why is this so?)
Instructions for Continued Airworthiness (ICAW) for Each of the Aircraft and Engine Types Supported
To enable support for a range of activities it is necessary to have access to a full set of Type Certificate Holder (TCH) core related aircraft documentation:
- Aircraft Maintenance Manual (AMM)
- Illustrated Parts Catalogue (IPC)
- Wiring Diagram Manual (WDM)
- Structural Repair Manual (SRM)
- Standards Practices (SPM)
- Non-Destructive Testing (NDT)
As well as access to a myriad of support manuals related to Engine / APU and Component Maintenance.
Aircraft Maintenance Program (AMP)
Controlling the Aircraft Maintenance Program is typically the responsibility of CAMO Maintenance Planning Group – Managing The Short Term Maintenance Planning Tasks typically sits within the MCC Group.
Access to Aircraft Technical Log (ATL) DATA
To manage the ongoing status of the aircraft requires details of the Journey Details (hours Cycles & Landings) all Pilot Reports (PIREPS) as well as the status of any deferred defects.
Responding to Airworthiness Directives
The purpose of an AD is to provide notification of unsafe conditions, non-conformity with the basis of certification and other conditions affecting the airworthiness of the aircraft.
- ADs mandate actions to ensure the continued safe operation of an aeronautical product, and they may prohibit flight until corrective action is carried out.
- Ultimately, it is the operator through either the CAMO or MCC who must ensure that the operator’s aircraft remain in compliance with all applicable airworthiness directives and other mandatory maintenance requirements.
Service Bulletin Assessment
- Upon receipt of recommendations issued by the aircraft, engine, propeller and component manufacturers, which may be in form of service bulletins or equivalent documents, CAMO Engineering or MCC shall review those recommendations and make the determination of whether compliance is appropriate.
Summary of Engineering Related Tasks
- Review of manufacturers Service Bulletins, maintenance manual revisions, Airworthiness Directives etc.
- Awareness Regarding Operating experience/environment/aircraft configuration/mod status.
- Recurring defects/reliability program/addition of new aircraft/dispatch system.
Defect Control & Management
Except in the case of aircraft operating in accordance with the Minimum Equipment List (MEL) – The operators’ CAMO / MCC is responsible to ensure that all defects are rectified before the further flight of the aircraft.
- Any defect that is considered reoccurring (for example has occurred three times or more within the past month or the past 15 flight segments (whichever period is the shortest) must be flagged as a recurring defect and appropriate action taken.
- An investigation of the affected system should be considered, taking into consideration all previous occurrences of the defect and the actions taken to correct them.
- Any Maintenance or Troubleshooting itself should be recorded as a maintenance action regardless of whether such action rectifies the defect.
Tooling & Material Control
To maintain an effective aircraft maintenance control process, a cooperative working relationship must exist between production and supply.
- Effective maintenance of complex aircraft systems cannot be accomplished without an adequate material supply program.
- A material control process is required to ensure the timely availability of tooling & equipment in support of AOG, Minor & other ad hoc (defect rectification) maintenance activities.
