Rotorcraft service fixtures

A rotorcraft service fixture comprising:

• a fixture body;
• one or more rotor assembly connectors rigidly attached to or integral with the fixture body, the one or more rotor assembly connectors 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;
• one or more support connectors rigidly attached to or integral with the fixture body, the one or more support connectors 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;
• and
• wherein the one or more rotor assembly connectors and the one or more support connectors comprise a flexible thermoplastic polyurethane material or an elastomeric polymer.

A method for servicing a rotorcraft, the method comprising:

• providing a rotorcraft service fixture, wherein the rotorcraft service fixture comprises:
• means for removably attaching to a rotor assembly of a rotorcraft;
• and
• means for supporting a first component of the rotor assembly, the means for supporting rigidly coupled to the means for removably attaching and configured to immobilize the first component relative to a second component of the rotor assembly after the first component is partially detached from the rotor assembly during inspection or maintenance of the rotor assembly;
• and
• wherein the first component includes a rotor strap pack and the second component includes a pitch housing, and wherein the means for removably attaching is shaped and sized to couple to the pitch housing and one or more dampers;
• or
• wherein the first component includes a pitch link and the second component includes a swashplate, and wherein the means for removably attaching is shaped and sized to couple to the swashplate before the pitch link is partially detached from the rotor assembly;
• attaching a first connector of the rotorcraft service fixture to a portion of a rotor assembly of a rotorcraft;
• partially detaching a component of the rotor assembly;
• and
• immobilizing the partially detached component using a second connector of the rotorcraft service fixture during inspection or maintenance of the rotor assembly.
