Plain English Summary

3/10 complexity

Requires all Beechcraft 65 and 70 (Queen Air) aeroplanes—except those modified under Excalibur STC No. SA444SW or fitted with Lycoming IO‑720‑A1A/A1B engines—to have powerplant fire detection and extinguishing systems acceptable to the Civil Aviation Safety Authority. Owners/operators must pay for installation or rework (the Hawker de Havilland system at Drawing No. 05‑D‑567 needs additional work); two supplier kits are noted as conforming. Compliance was required before further flight after 31 December 1986.
