 SCHEDULE OF AIRWORTHINESS DIRECTIVES

 British Aerospace BAe 146 Series Aeroplanes

AD/BAe 146/50 Generator Control Unit 8/94

 Applicability: All series BAe 146 aircraft.

            Requirement: Action in accordance with Avro International Aerospace Mandatory Inspection Service Bulletin S.B.24-103 dated 24 March 1994.

            Note: CAA(UK) AD 014-03-94 refers.

 Compliance: Prior to 30 November 1994.

            Background: The CAA(UK) have advised that investigation of in-service generator control unit (GCU) failures has highlighted the possibility that GCUs repaired or rectified by workshops other than GEC-Marconi, may have the under-frequency trip level set too high. This Directive requires the one time inspection of GCUs for possible incorrect under-frequency trip level settings and, if necessary, adjustment of the settings. The CAA(UK) compliance time is extended by two calendar months.
