Airworthiness Directives; Saab Model SAAB 2000 Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Saab Model SAAB 2000 airplanes. This AD requires an inspection for cracking of the fastener holes in the front and rear spars, a modification of the fastener holes of the front and rear spars and the rear spar web, and related investigative/corrective actions if necessary. This AD is prompted by a report of cracking of certain fastener holes in the lower spar cap of the rear spar and in the lower skin at the front spar. We are issuing this AD to prevent cracking of the front and rear spars, which could result in fuel leakage and consequent reduced structural integrity of the wing structure.
