Federal Aviation Administration January 2011 – Federal Register Recent Federal Regulation Documents

We are superseding an existing airworthiness directive (AD) for the products listed above. This 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 earlier MCAI, Brazilian Airworthiness Directive 2007-08-01, effective September 27, 2007, describes the unsafe condition as:

We are adopting a new airworthiness directive (AD) for the products listed above. This 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:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive high frequency eddy current inspections for cracking on the hinge bearing lugs of the left and right sides of the center section ribs of the horizontal stabilizer, and related investigative and corrective actions if necessary. This AD was prompted by reports of cracks found on either the left or right (or in one case, both) sides of the center section ribs of the horizontal stabilizer. We are issuing this AD to detect and correct cracking in the hinge bearing lugs of the center section of the left and right ribs, which could result in failure of the hinge bearing lugs and consequent inability of the horizontal stabilizer to sustain the required loads.

We are superseding an existing airworthiness directive (AD) that applies to the products listed above. This 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:

We are adopting a new airworthiness directive (AD) for the products listed above.

The MCAI describes the unsafe condition as:

The FAA has issued a ROD for the Philadelphia International Airport (PHL), Capacity Enhancement Program (CEP), Environmental Impact Statement (EIS). The City of Philadelphia, the airport sponsor, owns and operates PHL and had requested FAA consider ways to accommodate existing and forecasted aviation demands. The purpose of the CEP is to enhance airport capacity in order to accommodate current and future aviation demand in the Philadelphia Metropolitan Area during all weather conditions. This ROD sets forth FAA's final determination and environmental approvals for the federal actions necessary to implement the CEP at the airport.

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to the products listed above. The agency docket No. and the engine type in the subject heading and paragraph (c) in the Summary section and the Regulatory text are incorrect. This document corrects that error. In all other respects, the original document remains the same.

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.

We are revising an earlier proposed airworthiness directive (AD) for the products listed above. That NPRM proposed replacing the power control relays for the fuel boost pumps and override pumps with new relays having a ground fault interrupt (GFI) feature. That NPRM was prompted by results from fuel system reviews conducted by the manufacturer. This action revises that NPRM for all airplanes by proposing to require an electrical bonding resistance measurement for certain GFI relays to verify that certain bonding requirements are met. This action also revises that NPRM by proposing to require, for certain airplanes, an inspection to ensure that certain screws are properly installed, and re-installing longer screws if necessary. We are proposing this supplemental NPRM 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. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

The FAA amends its regulation concerning the process for requesting a waiver of the mandatory separation age of 56 for Air Traffic Control Specialists in flight service stations, enroute or terminal facilities, and the David J. Hurley Air Traffic Control System Command Center. Under this final rule, Air Traffic Control Specialists will no longer be required to certify they have not been involved in an operational error (OE), operational deviation (OD), or runway incursion in the past 5 years. The rule will streamline the waiver process and bring it into conformance with current FAA OE and OD reporting policy.

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.
