Control of Deferred Items and History
How does your Airline control deferred items ?
In your deferred items list how do you know if the same item has been closed as fixed.
The item may have a history of being fixed and then reappears again.
The MEL Cat C items get closed but then come back again.
How long does your company keep the technical log history of maintenance defects ?
You can write up a item such a BSCU 1 Fault in the A 320 and it gets closed by one engineer Ground Test ok, the other investigates and finds the wiring problem.
Say you want to look back into the history of a deferred item in your company but the tech log book is not on the aircraft ?
Curious to policies on these questions on different airlines.
