Abstract

A rotorcraft service fixture includes a fixture body and one or more rotor assembly connectors rigidly attached to or integral with the fixture body. The one or more rotor assembly connectors are sized and shaped to provide an interference fit with a portion of a rotor assembly of a rotorcraft to removably attach the fixture body to the portion of the rotor assembly. The rotorcraft service fixture also includes one or more support connectors rigidly attached to or integral with the fixture body. The one or more support connectors are sized and shaped to provide an interference fit with a partially detached component of the rotor assembly to immobilize the partially detached component during inspection or maintenance of the rotor assembly.
