Airworthiness Directives; Jetstream ATP Airplanes

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Jetstream ATP airplanes. This proposal would require inspections to detect fatigue cracking and corrosion in the gussets of the rear passenger door and rear baggage door apertures, and replacement of the gussets, if necessary. This proposal is prompted by fatigue tests which indicated that fatigue cracking and corrosion can occur in these gussets. The actions specified by the proposed AD are intended to prevent degradation of the structural integrity of the fuselage pressure vessel due to the problems associated with cracking and corrosion in the gussets of the rear passenger door and rear baggage door apertures.
