Continued or continuing airworthiness: which one is actually your responsibility?
The two words get used interchangeably, including by people who are contractually
responsible for one of them. They are not the same thing, and they do not belong to
the same organisation.
Continued airworthiness belongs to the design. It covers:
◆ The type certificate holder, not the operator
◆ The aircraft type, not your individual tail number
◆ Service Bulletins, repair designs and design changes
◆ The Airworthiness Directive, once the Agency mandates it
Continuing airworthiness belongs to the aircraft. It covers:
◆ The owner, or the operator in commercial air transport
◆ Your aircraft, serial number by serial number
◆ The maintenance programme, and the evaluation of every AD and SB against your fleet
◆ The records, and the airworthiness review behind every ARC
One keeps the design safe. The other keeps your aircraft safe. The Airworthiness
Directive is the exact point where one becomes the other: the design organisation
writes it, and your CAMO decides what it means for the aircraft parked on your stand
tonight.
Only one of those two is a responsibility you can delegate. Continued airworthiness
stays with the people who designed the aircraft. Continuing airworthiness stays with
you, and a CAMO carries it on your behalf. That is the side Dedalus Aviation Services
works on.
Behind Every Safe Landing.
To the CAMO managers reading this: from the moment an AD is published, how long does
it take you to know whether it touches your fleet? Same day, or same week?
