Thanks for correcting me Hoverbover. You are right. Keep it in trim and that problem will not appear unless the conditions are right.. .. .Not sure if this applies for the whole tailboom, but when the test pilot (do not remember his name)lost the tailboom during testing, he used the collective to keep the attitude under control and get it to the ground without being a lawn dart. He gave a lecture about it where I work and it was pretty interesting.. .. .There is also a rumor running around about several other cracks in different locations other then the one the AD covers. If so, MD is doing a pretty good job covering it up.. .. .Last I heard about the GAO report, the YSAS fixed most of the problems (covered it up).
