Federal Aviation Administration April 20, 2011 – Federal Register Recent Federal Regulation Documents

We propose to supersede an existing airworthiness directive (AD) that applies to the products listed above. The existing AD currently requires revising the Limitations section of the airplane flight manual (AFM) to advise the flight crew of procedures to follow to ensure that a fuel filter impending bypass condition due to gross fuel contamination is detected in a timely manner. Since we issued that AD, a new design change has been developed that will correct an error in the operating program software (OPS) of the engine indication and crew alerting system (EICAS). This proposed AD would require installing new OPS (Version 7) of the EICAS in the EICAS computers. This proposed AD would also require various concurrent actions, depending on the airplane configuration, including installing a certain EICAS OPS version, making wiring changes, replacing the audio accessory unit, replacing certain handsets and EICAS computers, changing EICAS computer connector keying, and loading Operational Program Configuration (OPC) software. This proposed AD also retains the existing AD provision that relieves certain airplanes (those equipped with certain EICAS OPS versions) from the proposed requirements. Accomplishment of the new proposed actions would terminate the requirements of the existing AD. We are proposing this AD to prevent malfunction and thrust loss on both engines, which could result in a forced off-airport landing.

This action amends Class E airspace at Point Lookout, MO, to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at M. Graham ClarkTaney Field Airport, Point Lookout, MO. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires inspecting the fuselage surface for corrosion and cracking behind the external adapter plate of the antennae installation, and repair if necessary. This AD was prompted by a report of a crack found behind the external adapter plate of the antennae during inspection. Similar cracking was found on two additional airplanes, and extensive corrosion was found on one airplane. We are issuing this AD to detect and correct corrosion and cracking behind the external adapter plate of the antennae of certain damage-tolerant structure, which could result in reduced structural integrity and consequent rapid depressurization of the airplane.

The FAA proposes to rule and invites public comment on the release of land at the Houma Terrebonne Airport, Houma, Louisiana. The property consists of two small parcels of land, together with all the improvements situated thereon, and all the rights, ways, privileges, servitudes and advantages thereunto belonging or in anywise appertaining. This land is located approximately 4,700 feet west of the Houma Terrebonne Airport, of Houma, Louisiana. The land in question was acquired by the Terrebonne Parish on June 17, 1958, through provisions of the Federal Property Administrative Services Act of 1949 (63 Stat. 765), the Surplus Property Act of 1944 (58 Stat. 765) as amended thereby. As airport owner, the Terrebonne Parish has requested to release two parcels in an effort to obtain additional funding for airport improvement at the Houma Terrebonne Airport. As part of this release, this parcel will change from aeronautical to non-aeronautical use and be limited to some type of commercial or industrial use under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).
