Plain English Summary

2/10 complexity

Requires a yellow arc marking (12–18 psi) on the left and right engine fuel pressure gauges of Aerostar (Piper/Ted Smith) Model 601 and 601P aircraft, to be applied within 100 hours time-in-service after 30 November 1980. Owners/operators must ensure compliance.

This one‑off, visible cockpit marking aims to reduce engine‑failure risk from excessively lean mixtures; the owner/operator bears the cost and scheduling, and no instrument replacement is mandated.
