Plain English Summary

2/10 complexity

This AD requires owners/operators of SIAI Marchetti F260/F260B/F260C/F260D aircraft (serial numbers up to 749) to inspect and secure the aileron balance-weight screws per Service Bulletin 260‑B52.

Initial inspection is within 10 flight hours after 23 Sept 1987 and repeat inspections every 50 flight hours to prevent detached weights, which can cause severe aileron flutter and possible loss of control.
