AMM Task
 

This is probably a stupid question, but I'll ask anyway...

Take, for example, AMM TASK 71-13-00-200-010 ('Detail Inspection of the FCDs') for the A318/19/21/21. This task is not stated in the MRB or the associated MPD.

What is, therefore, the reason for this task being there?

Obviously inspections of the cowling are required, but I want to know what drives such an inspection to be in the AMM when it isn't instructed by the MRB/MPD.

Many Thanks

Hi Gen,
I've just looked at the AMM and it states the following:-
TASK 71-13-00-210-010
General Visual Inspection of the Fan Cowl Hinge Fittings
1.

Reason for the Job

Refer to the MPD TASK: 711300-03


Cheers

The only stupid questions are the ones that aren't asked :ok:

The MPD doesn´t give it all...
 

GEnxsux,

A few more possibilites for "orphan" AMM tasks:

- There used to be an MPD / MRBR item in previous issues (or even other aircraft models!); AMM taks hasn´t been deleted.
- There will be a MPD / MRBR item in the next revision of these documents, but the AMM revision comes in advance (not bearing the MPD ref. as it doesn´t exist at that time).
- The AMM task is a TSM task.
- The AMM task is associated to the MEL (De-/Reactivation procedure).
- The task gives instructions for "routine" / "non-routine" work that is not driven by the maintenance programme, e. g. inspection of certain A330/A340 LP-valve actuators for correct dimensions at installation.

I suppose there are many more routes...! Maintaining airplanes is a lot more complex than the MPD makes us believe... ;)

Cheers,
