Airworthiness Directives; Robinson Helicopter Company Model R44 Helicopters

This amendment adopts a new airworthiness directive (AD) that is applicable to Robinson Helicopter Company Model R44 helicopters. This action requires removal of the push-pull tube sleeve guide assembly (sleeve guide) and replacement with a push-pull tube roller guide assembly (roller guide); and, inspections of the push-pull tube sleeves for signs of wear and replacement as necessary. This amendment is prompted by a report of an operator experiencing binding in the cyclic control system caused by torn heat-shrink material (material) on the cyclic push-pull tubes binding in the sleeve guide. The actions specified in this AD are intended to prevent binding in the cyclic control system and subsequent loss of control of the helicopter.
