Thanks. We found corrosion in the pin M in the plug horses coller . We repaired the pin and the problem resolved.

Hi there after changing propeller #1 we did reindexing but engine #1 doesn't go to over speed . RPM fixed at 100% with Fuel flow 2400. So the pitch lock can't intervene . As operation effected. _change the synchrophaser. _change the valve housing. _Change the propeller assembly. _ change the engine #1 . _ Continuity and insulation measurements between valve housing and syn . But still the same problem. (Engine #1 doesn't pitch lock) Any solution please.
