Xair F wing warp mystery
An Xair F with two pob on a stabilized approach. The tochdown was hard. Due to the lack of communication between the pf and the pnf , after touchdown the throttle was set to full power and the aircraft veered off the runway surface. The throttle was finally moved to idle cut off position and the engine subsequently shut down.
the inspection showed no damage to undercarriage, no debris on the wing surface to indicate any strike of the wing surface.
A test flight was later conducted and it was noticed that the aircraft had a tendency to yaw towards the right once full throttle was opened.
On close inspection the right wing indicated a warp (downwards) from the wing root to the wing tip.
jst wondering how d warp occured?
