This AD requires owners/operators of BAe Jetstream Series 3100 aeroplanes (c/n 601–749) to modify the engine/throttle system per BAe Service Bulletin 27-JM7561 Rev 1 so take-off power cannot be achieved while any gust lock is engaged. It was issued after an attempted take-off with a partially engaged gust lock; operators must arrange and pay for the work and comply by 30 April 1989.

Amdt 1

Gust Lock/Throttle Interlock 2/89 DM

Applicability: Series 3100 constructors numbers 601 to 749. Requirement: Action in accordance with BAe SB 27-JM7561 Rev 1. Compliance: Prior to 30 April 1989.

Background: There has been an incident where take-off was attempted with the rudder gust lock partially engaged. Incorporation of this SB ensures that take-off power cannot be achieved without all three gust locks having been disengaged. Rev 1 of the Service Bulletin provides amended rigging instructions for those aircraft that could not physically meet the initial requirement.
