Operation of the aircraft without certain secondary airframe and engine parts is possible as indicated in Master Configuration Deviation List (MCDL). Any part not included in this list must be considered as necessary.

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

The MCDL maintenance procedures are published in the AMM.

Use of high-speed tape

When items require high-speed tape, the MCDL dispatch conditions are assessed considering that the tape is in the correct position and in good condition.

According to A320F AFM, Unless otherwise specified in the MCDL item or the relevant AMM task, a visual inspection of the high-speed tape must be made at a regular interval that must not exceed 3 calendar days.
