I checked the thread this morning and was surprised and happy to see the replies. Thanks again guys. I don't claim to know everything about the Huey, (I have 500 hrs on type. All ag work and lifting) and I am open to the thought that it may have been "pilot induced", but after it happened a few times I double checked everything I was doing on the sticks and pretty much ruled that out. It wasnt a problem pulling 50psi getting the loads off the ground, and transition was ok.
We pushed her back in the hangar and the engineer is going to have a good think about things over the weekend...... Hopefully we can sort something next week. We do have a set of trans mounts coming from the states so I was thinking that was the problem. But I will show him the thread on the office puter on Monday. Maybe there will be things that will jog his memory.
Sat down with a bottle of James B Beams finest last night to settle the nerves and the world seems like a much better place this morning
Thanks again guys. Fly safe out there.
