Abstract
A hand-held check fixture to indicate excessive play in a pitch change link ball joint is provided. The check fixture can include a first member for attachment to a first portion of the pitch change link, a second member for attachment to a second portion of the pitch change link, and a gage to indicate movement of the first member relative to the second member. The gage is adapted to indicate the clearance between a pitch change link ball bearing and a pitch change link knuckle in the axial direction and/or in the radial direction. The check fixture can assist in evaluating the flightworthiness of each pitch change link on a rotor assembly with relative ease and without requiring the complete removal of each pitch change link from the rotor assembly.
