Well for a while anyway!
Who was the genius that elected
NOT to change the tail rotor gearbox prior to the air test following repairs.
Seems the unchanged gearbox got smoking hot and showed ugly signs of not being serviceable and after it cooled down enough to be touched....was changed.
I wonder if the tail rotor drive shaft was changed?
Would the Eurocopter (Aerospatiale) tech manual set forth a "sudden stoppage" inspection procedure? Surely, the damage incurred during this incident would have justified such an inspection and component changes for everything involved.
Or am I being over cautious here?
Anyone in the loop that can explain just how that decision was arrived at?
Lt. Fubar in post number 61 of this thread posted the following.....
Well the fan was disaligned at the impact, so all of the blades will have to be replaced, the whole fenestron gearbox checked, repaired, or replaced, the duct will have to be replaced, so is the whole skin. Than the drive train, whole tail section checked for cracks, bends, material strains. Don't know where the tail fan drive train goes in the EC155, so that parts will have to be checked also.
Too cut it short - the while tail will have to striped down, checked and every component repaired/replaced. The whole thing is very serious - many fast-spinning, precise-machined, very important parts out there
