Plain English Summary

2/10 complexity

This AD mandates replacement of certain Generator Control Units on affected BAe 146 series aircraft, to be carried out per BAe 146 Mandatory Alert Service Bulletin 24‑A97 and completed by 17 November 1991. It targets operators/owners of aircraft within the AD’s applicability because the GCUs may fail to detect a single‑phase feeder open circuit, risking inaccurate instrument readings. Compliance requires parts, maintenance time and associated downtime.
