Plain English Summary

4/10 complexity

This airworthiness directive requires owners/operators of specific Piper PA‑31 aeroplanes (listed serial numbers) to remove the fuel control panel, inspect wiring and the fuel crossfeed line for chafing, replace damaged items, and reroute/secure the line using Piper Service Bulletin No.278 and Kit No.760216. It imposes tight compliance deadlines and is intended to address chafing that could cause fuel leaks or electrical faults, so affected operators must arrange inspections, parts and modifications.
