Plain English Summary

4/10 complexity

This Airworthiness Directive requires operators of specified SAAB SF340A and SF340B aeroplanes to carry out modifications and inspections per SAAB service bulletins to prevent selection of power levers below the flight idle stop in flight. It sets firm compliance deadlines and, by Amendment 1, delays a compliance date to 30 June 1997 because modified power quadrants were unavailable. The directive targets aircraft owners/operators of the listed serial numbers and matters because the work addresses a cause of at least one accident and several incidents.

Background: The manufacturer has advised that power levers have been selected below the flight idle stop position whilst the aircraft was airborne. This has resulted in an aircraft accident and several other incidents of uncontrolled aircraft flight.

Amendment 1 defers the compliance date to 30 June 1997 following advice from the Swedish CAA that due to a lack of modified power quadrants compliance by 31 December 96 could not be achieved.

The original issue of this Airworthiness Directive became effective on 17 May 1995.
