Plain English Summary

3/10 complexity

Requires inspection of the propeller governor arm on specified SIAI Marchetti S205 (S/Ns up to 5-406) and S208 (S/Ns up to 4-64) aircraft per SIAI MARCHETTI Service Bulletin 205B43A, and allows fitting a steel governor arm (P/No. 260-13-274-01) as terminating action. Initial compliance is within 25 hours time in service from 10 November 1994, then every 50 hours. The AD responds to reported cracking because failure can cause loss of propeller control; owners/operators must pay for and carry out inspections and any replacement.
