The FAA is revising an earlier proposal for Robinson Helicopter Company (Robinson) Model R66 helicopters that proposed to require replacing a certain part-numbered tail rotor (T/R) drive shaft yoke assembly (yoke assembly) and inspecting for sealant. The NPRM was prompted by reports of T/R drive shaft forward hanger bearing failures. This action revises the NPRM by expanding the applicability, changing the proposed requirements, and correcting nomenclature. Since this imposes an additional burden over that proposed in the NPRM, the FAA is reopening the comment period to allow the public the chance to comment on these changes.
