Said AC, nose gear doors would open during flight, pull the lever up and they would immediately close then re-open a short time later(2 mins?). As I understand there are two different actuators under the front engine, one, right inside the gear doors and another larger actuator that moves the nose gear itself.
My question is replacing the "o" rings in either actuator. What would be the hours involved with each? Second question, would replacing the nose gear actuator o rings solve the gear doors drooping during flight?
Fire away.
Thank you!
