No problems here with the linear actuators. Two high-time A/C well over 5000 hrs, total with 4 A/C about 15000 hrs. and I believe 5 actuator replacements since we started with the AB/AW139 in Jan. 2006.
Important is preventing the wiring from sharp bends, databusses don't like that.
Talking about crappy linear actuators: what about the Hamilton Standard actuators in the S-76 models? TBO is 2500 hrs. Every time an actuator makes it to its TBO we get cake from the management ....... we don't eat much cake over here
