Airworthiness Directives; Saab Model SAAB 2000 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB 2000 series airplanes, that requires modification of the airplane by coldworking fastener holes at the front and rear wing spars and by installing modified support angles for the lower trailing edge panel of the wing. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent fatigue cracking in the lower spar cap of the wing rear spar and in the lower skin at the wing front spar, just outside the nacelle, on the left-hand and right-hand side of the airplane, which could result in fuel leakage and consequent fire in or around the wing.
