'Problem' aircraft and systems were very much dependent on MoD's (or A.M.'s) PE or equivalent. Two examples - the civilian Viking noted,and took remedial action for, wing spar cracks. The same problem, obviously, was occuring in the Valetta but no remedial action was taken until one of the 'Pigs' out of Aqaba folded its wing. All grounded and inspected - out of our 14 squadron aircraft 12 had cracked main spars and skin wrinkles.
On S&R Whirlwinds we used to have frequent 'birdcaging' on the winch cables because of poor cable 'lay'. At the 'Wastelands' meeting to discuss/remedy this, I mentioned, in passing, that we had occasional hyd motor 'pauses', easily solved by reselection but the focus immediately changed to the less important matter. We did, eventually get the Lebus drum but it could easily have been diverted.
