Plain English Summary

3/10 complexity

This airworthiness directive requires owners/operators of Piper PA-44-180T aeroplanes (specified serial numbers) to follow Piper Service Bulletin No. 847 to reposition and securely support the ammeter shunt so the 20-gauge ammeter wires do not carry mechanical loads. Compliance is required within 100 hours time-in-service after 31 December 1986 to address reported loose or shorting ammeter connections that could lead to electrical failure or cockpit fire.
