The FCU was a bone of contention over a year ago, its mentioned back a few pages in this never ending thread.
Its an item that was giving problems then. One of the reasons most starts went to Emergency Governor had to do with this item. We call that a big red X (grounding authority) Its also something that when repair is required it has to be sent back to an authorized repair station, mainly for the Calibration. Shade Tree Mechanics were only allowed to box it up to be shipped out....They know that in CT
Putting in a -11 engine means its the UH-1D category vs. -13 for the UH-1H. That requires a new Airworthiness Certificate (at Least under FAA rules), but since they dont have one anyway, who cares.
As to the tailboom, just remember there are only four bolts that hold that puppy on there. Part of the preflight requires a hands on check to see that there is no seperation between the body of the aircraft and the tailboom. If it hit as hard as you mentioned the tail stinger may be bent, if thats so the area where it attaches should have damage. We used to paint tail stingers and "he who comes home with paint missing (and it is acceptable) buys the beer." I know of one actual autorotation where the idiot rotated so far that he got the tail rotor instead of the stinger. That was just the beginning of his problems.
Also HUEYS DO NOT backfire. Thats usually something attributable to a failing engine.
Last but not least SACAA seems out of the picture after getting their ass whipped in the courts.
Again we see that that Huey is one aircraft thats hard to hurt......
