Airworthiness Directives; Jetstream BAe Model ATP Airplanes

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Jetstream BAe Model ATP airplanes. This proposal would require repetitive inspections to detect damage of the antenna mounting reinforcing plates and surrounding fuselage skin. If any damage is detected, the proposed AD would require replacement of the reinforcing plate with a new reinforcing plate and/ or repair the surrounding fuselage skin, which would terminate the repetitive inspection requirements. This proposal is prompted by reports of corrosion found at the antenna reinforcing plates, which was caused by the ingress of water at the plates. The actions specified by the proposed AD are intended to prevent such corrosion, which could result in reduced structural integrity of the fuselage pressure vessel.
