Plain English Summary

2/10 complexity

Operators of BAe 146 aircraft fitted with lift‑spoiler jacks P/N P308‑45‑0002 or P308‑45‑0102 must have the lift‑spoiler “unlocked” indication inspected/serviced per British Aerospace Mandatory Inspection SB 27‑137 by the next scheduled microswitch check or by 31 Dec 1994, unless already done. The AD implements the manufacturer’s fix for a reported dormant failure of the indication system; compliance and costs fall to the aircraft operators.
