Federal Aviation Administration October 19, 2009 – Federal Register Recent Federal Regulation Documents

This notice contains a summary of a petition seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

The FAA assigned the Aviation Rulemaking Advisory Committee (ARAC) a new task to provide advice and recommendations to the FAA about the current ARAC process. This notice informs the public of the new ARAC activity.

We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 757 airplanes. This proposed AD would require replacing the power control relays for the fuel boost pumps and override pumps with new relays having a ground fault interrupt (GFI) feature. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent damage to the fuel pumps caused by electrical arcing that could introduce an ignition source in the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

We are revising an earlier proposed airworthiness directive (AD) for all Boeing Model 757-200, -200PF, -200CB, and -300 series airplanes. The original NPRM would have required an inspection of the two spring arms in the spin brake assemblies in the nose wheel well to determine if the spring arms are made of aluminum or composite material, and repetitive related investigative/corrective actions if necessary. The original NPRM resulted from reports of cracked and broken aluminum springs. This action revises the original NPRM to include a parts installation paragraph and to provide options for terminating the repetitive actions. We are proposing this supplemental NPRM to detect and correct cracked or broken springs. A cracked or broken spring could separate from the airplane and result in potential hazard to persons or property on the ground, or ingestion into the engine with engine damage and potential shutdown, or damage to the airplane.

This action establishes Class E Airspace at Spencer, WV. This action enhances the safety and airspace management of Boggs Field Airport, Spencer, WV.

This action amends Class E airspace for the Peoria, IL area. Additional controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAP) at Mount Hawley Auxiliary Airport, Peoria, IL. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at Mount Hawley Auxiliary Airport.

This action amends Class E airspace for the St. Louis, MO area. Additional controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAP) at Spirit of St. Louis Airport, St. Louis, MO. Also, this action makes minor adjustments to the geographic coordinates for the Lambert-St. Louis International Airport, St. Louis VORTAC, and the Foristell VORTAC. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at Spirit of St. Louis Airport.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Reports have been received of finding corrosion at the Frame 29 wing-to-fuselage attachment lug plate joint. This condition, if not detected and corrected, could result in a degradation of the structural integrity of Frame 29 and the wing-to-fuselage attachment.
