Study Notes
Maintenance and Operations Philosophy
- A philosophy exists to ensure safe operations during takeoff from maintenance bases or en-route stops.
- Operators must maintain close operational control to prevent dispatching aircraft with multiple Minimum Equipment List (MEL) items inoperative.
- Assessment of any interrelationships between inoperative systems is crucial to avoid safety degradation or added crew workload.
MEL Guidelines
- MEL is not designed for extended aircraft operation with unserviceable items.
- Repairs for unserviceable MEL items should be made at the nearest station capable of performing the work and must be completed at the flight termination station to avoid potential removals from service.
Exclusions from MEL
- Items affecting airworthiness, such as wings, flight controls, engines, and landing gear, are not included in the MEL.
- Non-essential items, including galley equipment and entertainment systems, that do not impact airworthiness, are also excluded.
Airworthiness Requirements
- All items impacting the aircraft's airworthiness or passenger safety must be operational and are not permitted to be included in the MEL.
Framing the MEL
- The MEL must be framed based on the Master Minimum Equipment List (MMEL) and include the latest revisions approved by the relevant regulatory authority.
- Customization of the MEL should consider operational specifications, aircraft configuration, modification status, and regulatory requirements.
- Deviation from flight manual limitations or emergency procedures is not permitted unless stated otherwise by the regulatory authority or flight manual.
Preamble and Rectification Intervals
- Operators must outline their philosophy for invoking the MEL in the preamble.
- The preamble should also specify defect rectification intervals as defined in the MMEL.
- MEL items are categorized into:
- Category ‘A’: Items requiring repair within the specified time interval in the remarks column.
- Category ‘B’: Items needing repair within three consecutive calendar days, excluding the day of malfunction recording.
