Requirement: 1. Test the smoke detectors for serviceability in accordance with British Aerospace, Regional Aircraft Limited, Service Bulletin SB.26-A38 Revision 1 dated
20 October 1998.
Note: This Inspection Service Bulletin has been classified Mandatory by the CAA(UK).
Compliance: 1. Prior to the 18 December 1998 and thereafter at intervals not to exceed 48 hours.
Incorporation of Mod No HCM56094A, B and C (SB 26-38-56094A, B and C) is terminating action for these repetitive inspections.
This Airworthiness Directive becomes effective on 16 December 1998.
Background: During in-service trouble shooting of the smoke detectors it was found that operation of the flight deck smoke detection test switch can give a serviceable indication, even though the detector light source filament is blown. This directive introduces terminating action and supersedes AD/BAe 146/62 which is cancelled.
