Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
This AD applies to Gulfstream Aerospace LP Model Gulfstream 100, Astra SPX, and 1125 Westwind Astra airplanes, certificated in any category, serial numbers 004, and 011 through 158 inclusive.
We are adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream 100, Astra SPX, and 1125 Westwind Astra airplanes. This AD was prompted by a report indicating that the main entrance door (MED) opened during flight, and by the determination that the "CABIN DOOR UNLOCK" crew alerting system (CAS) message may extinguish before the handle latch pin is fully engaged. This AD requires accomplishing an updated rigging procedure for the adjustment of the MED microswitch. We are issuing this AD to address the unsafe condition on these products.
Within 12 months after the effective date of this AD: Do an updated rigging procedure for the adjustment of the MED microswitch, in accordance with the Accomplishment Instructions of Gulfstream G100 Service Bulletin 100-52-312, dated January 15, 2016.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
