Federal Aviation Administration October 27, 2010 – Federal Register Recent Federal Regulation Documents

We are revising an earlier proposed airworthiness directive (AD) for the products listed above. That NPRM proposed to retain the inspection requirements of AD 2009-09-09 and add a terminating action for the repetitive inspection requirements. That NPRM resulted from the manufacturer developing a modification that, when incorporated, would terminate the repetitive inspections required by AD 2009-09-09. Since we issued the earlier NPRM, the manufacturer revised the service information to include additional airplane serial numbers into the Effectivity section and revised the modification kit instructions. This action revises that NPRM by adding airplanes to the Applicability section and incorporating new service information. We are proposing this supplemental NPRM to retain the inspection requirements of AD 2009-09-09 and add a terminating action for the repetitive inspection requirements using the revised service information. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

This establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
