 |
|
While giving a biannual to a friend in the 10 this morning, we were stalling the aircraft. At times we got slow enough to get the prestall buffet. When I looked back at the right hoizontal stab and elevator, I could see a lot of movement. Considering that the IO360 RV10 (220RV?) had 1000+ hours of landings and stalls in training, this may be a reason for the cracks forming. We inspect each annual and have found no cracks or even wrinkles.
We also found that the aircraft becomes slightly unstable near the stall prior to the buffet and a slight sink rate developes, therefore we plan to use this to avoid the pre stall buffet and subsequent shaking of the tail.
Stall occurred at 53 KIAS with half flaps and 2400#

There were a lot fewer than 1000 hours on N220RV and a lot of history that went with the creation of the SB. Just glad no one else found any. John #40600
