Least Favorite Maintenance Tasks
Ha. But don't know if a lobotomy was enough with some items. Never seen a Peugeot/Renault box but have seen pic-tickets or the part itself stamped with vehicle brands on AS parts. The factory nose external load mirrors were everyday truck mirrors and the Lama ones I saw had Renault stamped on the back of the mirror. But no different than the Castrol oil used for EC135 transmission, same stuff for a Mercedes except for that LBA sticker on the back and an increase in price. Not a bad thing really as they've used vehicle parts rebranded as aircraft parts in aviation for eons.
S76 used Dexron II in the main gearbox, automotive transmission fluid.
I dont see a problem with using commercial parts if suitable. Its the price mark up that is the problem!!!
Nothing wrong with the use of non aviation specific parts if approved by the authority, once flew a brand new fixed wing whose production fuel cap came from a Ford Falcon as did the coil spring used on the nose wheel. The Dextron oil was developed for GM and its automatic transmissions, we had problems using it in the 76 as after some hours had been accrued in hot weather we suffered a loss of oil pressure yet the oil still passed all the specification tests, presumption by the scientific folk was that in being forced through the transmission oil jets the long chain molecules were being chopped into shorter chains, I'd have thought that would make for a loss of viscosity but apparently not. We swapped to Mobil Jet, no further problems.
The 3 dynamic absorbers in the nose & under the cockpit seats of a CH-47 were no fun to replace - heavy & awkward. Sounds like they finally got rid of them in the F models & are using a much lighter active unit.

A bit off thread, but there was a famous case in the RAF when the venerable Whirlwind was still on SAR duties. A new fitter straight out of training reported in, and the sergeant said, "Right lad go and do a Kerosene wash on that engine" so lad goes and gets a compressor wash rig, and fills it with neat Kerosine, after fitting the rig to the engine, the pilot says OK after lighting to ground idle, the lad turns the rig on full, the result can be imagined.
It was the sergeant who got the severe rep, he should have checked the lad knew what he was doing.
Another much older RAF story is of a fitter cleaning a Magneto in a bucket of Avgas, he spun it over, thus destroying an aircraft.

Greaed Heads....ah....memories of bales of greasy rags from wiping down Alouette and Llama rotor heads.....tail booms and tail rotors.
Then there was the added pleasure of undoing the mess and out of balance issues from leaking grease seals.
Loved flying them....but rag wiping was a full time job it seemed.

Ah yes.....the stack bearings and do remember the put the tail rotor blades on in the correct direction of rotation!
