Flight control work load
Not only the aileron bearings had to be changed often, but also the flight control PFCU's, I was working in the Hydraulic Bay at RAE "F" so was getting lots of work from XE531.
I was transfered to "A" Shed at the time of the engine failure, in charge of 2nd year apprentices and was detailed to take the lads out and map the runway and locate,identify and collect bits of the aircraft. This was too much of a job for one man and 10 apprentices.
