Federal Aviation Administration January 6, 2012 – Federal Register Recent Federal Regulation Documents

This action proposes to remove Class E Airspace at Southport, NC, and establish Class E Airspace at Oak Island, NC, as new Standard Instrument Approach Procedures have been developed at Cape Fear Regional Jetport/Howie Franklin Field. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport. This action also would recognize the airport name change to Cape Fear Regional Jetport/Howie Franklin Field and update the airport's geographic coordinates.

We are adopting a new airworthiness directive (AD) for all Model 737 airplanes. This AD was prompted by a report of extensive corrosion of a ballscrew used in the drive mechanism of the horizontal stabilizer trim actuator (HSTA). This AD requires repetitive inspections, lubrications, and repetitive overhauls of the ball nut and ballscrew and attachment (Gimbal) fittings for the trim actuator of the horizontal stabilizer; various modification(s); and corrective actions if necessary; as applicable. We are issuing this AD to prevent an undetected failure of the primary load path for the ballscrew in the drive mechanism of the HSTA and subsequent wear and failure of the secondary load path, which could lead to loss of control of the horizontal stabilizer and consequent loss of control of the airplane.
