Was getting ready to go to the field a few years back..airplanes were up on a shelf...stepped on the lower shelf to get the Mid Star 40 from the upper shelf..all is well airplane in hand...turned and looked before I stepped...hand slipped and down I came..let go of the airplane..but I still knocked the horizontal stab off.....Hangar rash happens..since you weren't in flight..It was hangar rash...tough break, I hope you are up and flying soon...by the way nice dead stick
