## Abstract

The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This AD requires repetitive detailed inspections of the aft fuselage frames for any discrepancies, and any applicable corrective actions. This AD is prompted by reports of corrosion found on the aft fuselage frames due to the ingress of water or liquid. We are issuing this AD to detect and correct corrosion of the aft fuselage frames, which could result in reduced structural integrity of the fuselage.
