Airworthiness Directive · Amendment 39-10502 · British Aerospace (Jetstream) Model 4101 Airplanes
British Aerospace (Jetstream) Model 4101 Airplanes
Jetstream Model 4101 airplanes, constructors numbers 41004 through 41079 inclusive; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace (Jetstream) Model 4101 airplanes, that requires a one-time inspection for corrosion of electrical connectors in certain areas on the pressure bulkhead and rear baggage bay areas, and repair, if necessary; and installation of improved sealing. 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 the accumulation of moisture inside the electrical connectors, which could result in a short circuit and consequent autopilot disconnect, or a latent failure of the stick pusher system.
