Airworthiness Directive · Amendment 39-12902 · Gulfstream Aerospace LP Model Astra SPX and 1125 Westwind Astra Series Airplanes
Gulfstream Aerospace LP Model Astra SPX and 1125 Westwind Astra Series Airplanes
All Gulfstream Aerospace LP Model Astra SPX and 1125 Westwind Astra series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all Gulfstream Aerospace LP Model Astra SPX and 1125 Westwind Astra series airplanes, that requires revising the Airplane Flight Manual to advise the flightcrew to don oxygen masks as a first and immediate step following a cabin altitude alert. This action is necessary to prevent incapacitation of the flightcrew due to lack of oxygen. This action is intended to address the identified unsafe condition.
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.
