8.6.2 CDL covers deficiencies in what?
Usually external items that affect aircraft PERFORMANCE.
(Aerodynamic fairings, reverser blocker doors, static discharges, etc)
- should usually have an associated PADD
CDL in AML is usually associated with what?
PADD
(Indicating loss in performance)
We had a CdL item once that didn’t have a PADD and it was actually wrong. As it should have some penalty.
What is interval A
Time interval as specified.
Calendar days:
Start is 00:01 on day after discovery

But!
Section 0 purpose and scope says:
PIC shall satisfy himself before the aircraft TAKESoff, that flight may commence in compliance with conditions of the MEL.
When is the MEL applicable up until?
Dispatch!?
Up until the time the aircraft moves under its own power (start of taxi).
If failure occurs after taxi but before take off, decision rests on PIC and good airmanship.
Consider (M), (O) and consultation with IOC also recommended.
Also consider that MEL’s do not account for multiple failures.
