What the Course is About

On the ground, an aircraft is considered “airworthy” when its “physical state matches its design”, and so it is considered to be in a good condition for a safe operation. However, you can also achieve an acceptable level of safety for an aircraft which has known failures –  and this is where the Minimum Equipment List (or MEL) comes in. The MEL is the operator’s tool which provides an approved way to determine the required conditions under which a flight can be commenced safely with inoperative equipment.

The Minimum Equipment List is a document which needs to be customised for a specific aircraft and required approval from respective National Aviation Authorities. The operator is ultimately responsible for the MEL customisation.

This course  follows EASA regulation, and covers most of the basic principles of MELs. It is aimed for aviation professionals who require a deep understanding of the regulation behind MELs together with know-how and good practices for how to customise and acquire approval for an MEL. The course is also ideal for other aviation professionals who want to deepen their knowledge on the subject.

Target Audience

This course is intended for aviation personnel who are responsible for customising MELs. It is also ideal for experienced MEL users, looking for a better understanding of MEL regulations and the customisation process. This course can also be used to complement operators’ training programmes to fulfil MEL training as stated in AMC1 ORO.GEN.110(e).
