## Abstract

This amendment adopts a new airworthiness directive (AD) that applies to Raytheon Aircraft Company (formerly Beech Aircraft Corporation) Models 58P and 58PA airplanes. This action requires inspecting for cracks in the right-hand (RH) upper and lower longeron near the second RH cabin window, inspecting for missing rivets in the cabin structure (longeron) adjacent to and aft of the second RH cabin window, repairing any cracked structure or reinforcing the longeron if it is not cracked, and installing rivets, if missing. Reports of cracks in the upper and lower longeron and missing rivets that are supposed to secure the frame, splice, and longeron together prompted this action. The actions specified by this AD are intended to prevent structural cracking to the cabin caused by missing rivets, which if not corrected, could cause decompression injuries to passengers, structural failure of the fuselage, and loss of the airplane.
