AW55-50/51SN Planet Repair

The AW 550 SN planet is a two bushings design. The bushing next to the gears is poorly supported. It spins in its housing, and until now has ruined the planet. We carefully bore the housing and install a one piece bushing. The bushing area now has plenty of support.

To see the cause of this failure check our repair of the AW 55-50&51SN cases.
