Abstract

A vane arm assembly (100) for a gas turbine engine (20) includes a vane stem (108) having a circumferential groove (120) axially spaced from an outer end of the vane stem. The assembly also includes a vane arm (102) defining an arm aperture (140) that the vane stem is disposed within. The assembly further includes a mechanical fastener (112) retaining an axial position of the vane arm in the axial direction. The assembly yet further includes a retention clip (114) having a base portion (126) and at least one clip arm (128), the base portion defining a clip aperture (130) that the vane stem is disposed within, the base portion disposed within the circumferential groove of the vane stem to couple the retention clip to the vane stem, the at least one clip arm including a retention member (168) engaged with the vane arm to provide redundant axial retention of the vane arm.
