Plain English Summary

2/10 complexity

This directive mandates that specific Piper PA‑31-325 C/R and PA‑31‑350 aeroplanes receive the elevator balance weight modification specified in Piper Service Bulletin No. 500. Affected owners/operators must have the work done by a qualified maintenance provider within 100 flight hours after 30 July 1976.

It matters because compliance is regulatory (owners pay for parts, labour and downtime), restricts operation until completed, and creates concentrated demand for authorised maintenance and parts suppliers for the listed serial-numbered aircraft.
