Federal Aviation Administration August 23, 2007 – Federal Register Recent Federal Regulation Documents

The FAA is revising an earlier proposed airworthiness directive (AD) for certain Boeing Model 747-400, 747-400D, and 747-400F series airplanes. The original NPRM would have required replacement of an electronic flight instrument system/engine indicating and crew alerting system (EFIS/EICAS) interface unit (EIU) located on the E2-6 shelf of the main equipment center with a new or modified EIU. The original NPRM resulted from two instances where all six integrated display units (IDUs) on the flight deck panels went blank in flight. This action revises the original NPRM by reducing the compliance time for replacing the EIU. We are proposing this supplemental NPRM to prevent loss of the IDUs due to failure of all three EIUs, which could result in the inability of the flightcrew to maintain safe flight and landing of the airplane.

This action will revise Class E airspace at Hoquiam, WA. Controlled airspace is necessary to accommodate aircraft using the Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Bowerman Airport. This will improve the safety of Instrument Flight Rules (IFR) aircraft at the Bowerman Airport, Hoquiam, WA.

This Rule 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.

The FAA is requesting public comment on the Town of Sanford, Maine's, request to convey approx. 2.58 acres of Airport property from aeronautical use of non-aeronautical use. The property is located on Gatehouse Road, Sanford, Maine. York County Registry of Deeds, book/ page/date 1113/303 12/30/47 & 1116/1 7/15/48. The property was acquired under AIP Project No. 3-23-0044-20. In exchange the airport will receive 2.9 acres of land for aeronautical purposes. The disposition of proceeds from the disposal of airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999.
