Final rule; request for comments.
Summary
We are adopting a new airworthiness directive (AD) for all DASSAULT AVIATION Model Falcon 10 airplanes. This AD requires a one- time inspection for cracking of the right-hand (RH) and left-hand (LH) inboard flaps, and replacement if necessary. This AD was prompted by reports of cracking found on the inboard end plate (rib) of the RH inboard flap. We are issuing this AD to detect and correct such cracking, which could lead to complete fracture of the rib and loss of integrity of the flap structure, resulting in loss of control of the airplane.
