Federal Aviation Administration May 4, 2010 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for certain Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F airplanes. This AD requires a one-time installation of electrical bonding jumpers for the fill valve controllers of fuel tanks. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent point-of-contact arcing or filament heating damage in the fuel tanks, which could result in fuel tank explosions and consequent loss of the airplane.

This document corrects a typographical error that appeared in airworthiness directive (AD) 2002-23-20 that was published in the Federal Register on November 29, 2002 (67 FR 71098). The typographical error resulted in an incorrect part number. This AD is applicable to Model FALCON 900EX and MYSTERE-FALCON 900 airplanes. This AD requires repetitive operational tests of the flap asymmetry detection system to verify proper functioning, and repair if necessary; repetitive replacement of the inboard flap jackscrews with new or reconditioned jackscrews; and repetitive measurement of the screw/nut play of the jackscrews on the inboard and outboard flaps to detect discrepancies, and corrective action if necessary. This AD also requires revision of the Airplane Flight Manual.

This action amends Class E airspace for Emmetsburg, IA, adding additional controlled airspace to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAPs) at Emmetsburg Municipal Airport, Emmetsburg, IA. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

This action amends Class E airspace for Mapleton, IA, adding additional controlled airspace to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAPs) at James G. Whiting Memorial Field Airport, Mapleton, IA. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

The FAA proposes to rule and invite public comment on the release of land at the Reading Regional Airport, Reading, Pennsylvania under the provisions of Section 47125(a) of Title 49 United States Code (U.S.C.).

The FAA is superseding an existing airworthiness directive (AD) for CFM International, S.A. CFM56-5B series turbofan engines. That AD requires reviewing exhaust gas temperature (EGT) monitoring records to determine EGT margin deterioration, and for airplanes where both engines have greater than 80 [deg]centigrade (C) of EGT margin deterioration, borescope-inspecting the high-pressure compressor (HPC) of both engines. That AD also requires removing from service any engine that does not pass the borescope inspection and, if both engines pass, replacing one of the engines with an engine that has 80 [deg]C or less of EGT margin deterioration. That AD also requires continuous monitoring of EGT margin deterioration on engines in service to prevent two engines on an airplane from having greater than 80 [deg]C of EGT margin deterioration. This AD:
