Minimum Equipment List (MEL) SOLUTIONS
An MEL lets you operate safely with certain items inoperative, under defined conditions and rectification intervals. We produce MMEL aligned, CASA Delegate approved MELs tailored to your aircraft and operation.
CASA DELEGATE PREPARED AND APPROVED AIRCRAFT SPECIFIC MINIMUM EQUIPMENT LISTS ACROSS AUSTRALIA
A NEW APPROACH TO MINIMUM EQUIPMENT (MEL) LIST SERVICES
Direen Aviation is introducing a more structured way for operators to obtain and maintain an approved Minimum Equipment List.
Moving beyond the traditional one-off MEL drafting model, the Direen Aviation MEL service range gives operators clear pathway options — from CASA Delegate approved MEL foundation support through to fully supported preparation, stronger post-issue protection, and digital-ready MEL data integration.
All packages are structured to produce a MEL tailored to the aircraft and operation presented by the client, supported through Direen Aviation’s in-house delegate approval process.

New MEL Development
Aircraft specific MELs developed from the MMEL and tailored to your operations, then directly approved by a CASA Delegate.
Direen Aviation develops complete, aircraft-specific Minimum Equipment Lists aligned with the applicable MMEL and tailored to each operator’s requirements. This includes operational and maintenance procedures, rectification intervals, configuration considerations and formatting to CASA standards.
A Direen Aviation CASA Delegate issues MEL approvals directly, delivering fast, compliant outcomes without the need for separate CASA submission.
MEL Amendments & Revisions
Keep your MEL aligned with aircraft changes, MMEL updates and operational needs with fast delegate-approved amendments.
MELs must be regularly maintained to reflect aircraft configuration changes, MMEL updates and evolving operational needs. Direen Aviation provides timely MEL amendments and revisions to ensure continued compliance and operational practicality.
Our CASA Delegate can approve amended MEL content directly, reducing administrative delays and providing operators with faster regulatory certainty.
MEL Extensions
Where permitted, MEL intervals may be extended. Direen Aviation’s CASA Delegate can assess and approve MEL extensions to maintain operational continuity.
Certain MEL items may be extended beyond their original rectification interval when justified and permitted under the MEL. Direen Aviation’s CASA Delegate can evaluate extension requests, assess airworthiness and operational risk, and issue MEL extension approvals directly where appropriate.
This service is particularly valuable for remote-area operations, aeromedical missions, FIFO logistics or unexpected maintenance constraints or extended parts delivery times.
DIRECT CASA DELEGATE MEL APPROVAL
A Direen Aviation CASA Delegate can develop, assess and approve your Minimum Equipment List (MEL) directly. This removes the need for separate CASA submissions, reduces delay and provides clear, fast regulatory outcomes for your operation.
