Airworthiness Directive · Amendment 39-10214 · Jetstream Aircraft Limited Jetstream Models 3101 and 3201 Airplanes
Jetstream Aircraft Limited Jetstream Models 3101 and 3201 Airplanes
Model 3101 and 3201 airplanes, serial numbers 693 through 870, certificated in any category, that have kit JK 2496 and modification JM 7537 installed.
This amendment adopts a new airworthiness directive (AD) that applies to Jetstream Aircraft Limited (JAL) Jetstream Models 3101 and 3201 airplanes that have kit JK 2496 and modification JM 7537 installed. This action requires installing magnetic latching relays on the ignition system because of the auto-ignition system becoming disabled when switching from ground power to the airplane's internal power. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by this AD are intended to prevent loss of the airplane's internal power connection to the auto-ignition system, which could cause loss of engine power and possible loss of control of the airplane.
