Study Notes
Minimum Equipment List (MEL)
- The MEL is specific to each aircraft and must not be used on any other aircraft, even of the same type.
- MEL is created using the Master MEL (MMEL) provided by the aircraft manufacturer and can be more restrictive but never less so than the MMEL.
- Exceptional permission to operate outside the MEL can be granted by the CAA, but not beyond MMEL limits.
- The Aircraft Commander decides on dispatching with multiple unserviceabilities, considering advice from specialists.
- Engineers must thoroughly review any maintenance requirements when invoking the MEL.
Configuration Deviation List (CDL) & Dispatch Deviation Guide (DDG)
- The CDL outlines any airframe components that may be missing at the time of dispatch; all non-listed parts must be present.
- The Master DDG integrates FAA MMEL and AFM CDL documents and incorporates recommended maintenance and operational procedures for dispatching aircraft with inoperative or missing equipment.
- Operators use the Master DDG as a reference to develop their own MEL.
Continuing Airworthiness
- Continuing Airworthiness encompasses all actions necessary to maintain an aircraft in a condition that is airworthy, as it was when built.
- The manual is designed for overhaul technicians in workshop settings rather than general aircraft mechanics.
Structural Repair Manual (SRM)
- The SRM contains essential information for identifying and repairing damage to aircraft structures.
- Tradesmen can use the SRM to assess damage and determine allowable limits and appropriate repairs.
- SRMs are generic for each aircraft type and not tailored to specific operators.
Master Minimum Equipment List (MMEL)
- The MMEL is developed by the Type Certificate holder and approved by the relevant authority, aiming to enhance aircraft utilization and thereby support economic air transportation.
- It lists equipment items related to airworthiness that may be inoperative while maintaining an acceptable safety level under certain conditions.
Minimum Equipment List (MEL)
- The MEL details significant unserviceable or inoperative items or systems affecting aircraft airworthiness at the time of dispatch.
- It includes operational limitations or maintenance actions applicable to the aircraft operating with defective systems.
- Any component not listed as unserviceable must be serviceable prior to dispatch, and defects must be logged and placarded if necessary.
- Operators compile the MEL which requires approval from the CAAS.
- Engineers achieving qualifications through this framework only receive Cat C privileges, while those holding B1 or B2 retain their additional privileges.
Air Operator Certificate Requirements (AOC)
- The Certificate of Maintenance Review (CMR) requires a signatory to confirm maintenance completion, compliance with mandatory inspections, rectification of defects, and issuance of necessary Certificates of Release to Service.
Certificate of Release to Service (CRS)
- A valid CRS must be issued before an aircraft can fly, certifying that maintenance tasks have been adequately completed.
- Certification can only be made by qualified personnel and must detail the work done and the certifier.
- No certifications are allowed if known defects could compromise flight safety.
- All aircraft components must possess a valid CRS before installation.
- Copies of each CRS and related maintenance data must be provided to the aircraft operator.
Maintenance Certification & Technical Logs
- Certifications for work done on an aircraft are recorded in the aircraft's technical log.
- For base maintenance checks, certification occurs on a worksheet which is then logged; components require certification on an Authorised Release Certificate.
