Summary
The FAA is revising an earlier proposed airworthiness directive (AD) for Airbus Helicopters Model SA330J helicopters that proposed to require replacing certain left-hand (LH) and right-hand (RH) hydraulic pumps. The NPRM was prompted by reports that bolts that attach the cover of the hydraulic pump were broken. 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.
