Configuration Deviation List (CDL)


A configuration deviation list (CDL) is a list established by the organization responsible for the type design with the approval of the State of Design which identifies any external parts of an aircraft type which may be missing at the commencement of a flight, and which contains, where necessary, any information on associated operating limitations and performance correction. (ICAO Annex 6: Operation of Aircraft)

The CDL is usually prepared by the aircraft manufacturer and is part of the Aircraft Flight Manual (AFM).

The CDL should not be confused with the MEL (MEL).

Regulations and supplementary information concerning the CDL are contained in JAR-OPS 1.
