Plain English Summary

2/10 complexity

This AD requires urgent fuel‑system modifications to certain Piper PA‑25 Pawnee crop dusters fitted with New Zealand Airwork wing‑tank kits (AW 396, 397, 401) to prevent engine failures caused by unequal tank air pressure and resulting fuel starvation. It affects owners/operators of those aircraft, who must alter the fuel system to meet CAR 3.446 (and ANO 101.17 para. 5.12 for ag planes). Modifications were required by the earlier of 100 flight hours after 30 Sep 1986 or 31 Dec 1986.
