Plain English Summary

3/10 complexity

This directive requires owners/operators of certain Piper PA‑44 Seminoles (specified PA‑44‑180 and PA‑44‑180T serial ranges) to inspect the aileron balance weight fixings before the next flight and then at intervals ≤25 flight hours until a mandatory modification is carried out. The modification referenced in Piper Service Bulletin No. 725A must be completed within 200 hours time‑in‑service after 21 August 1981.

It matters because loose aileron balance weights can detach; owners/operators pay the costs, and the pilot‑in‑command may perform and certify the interim inspections.
