Federal Aviation Administration August 13, 2012 – Federal Register Recent Federal Regulation Documents

We propose to supersede an existing airworthiness directive (AD) that applies to certain General Electric Company (GE) CF6-80C2 series turbofan engines. The existing AD requires replacement of the fuel tubes connected to the fuel flowmeter. Since we issued that AD, we received several additional reports of fuel leaks and two reports of engine fire due to mis-assembled supporting brackets on the fuel tube connecting the flowmeter to the Integrated Drive Generator (IDG) fuel- oil cooler. This proposed AD would require installing a new simplified one-piece bracket to eliminate mis-assembly. We are proposing this AD to prevent high-pressure fuel leaks caused by improper seating of fuel tube flanges, which could result in an engine fire and damage to the airplane.

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 any petition or its final disposition.

By Federal Register notice (See 77 FR 27835-27836; May 11, 2012) the National Park Service (NPS) and the Federal Aviation Administration (FAA) invited interested persons to apply to fill six upcoming openings on the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). The notice invited interested persons to apply to fill six vacancies representing commercial air tour operators (2), general aviation (1), Native American tribal (1), and environmental (2) concerns due to the incumbent members' completion of three-year term appointments on October 9, 2012. This notice informs the public of the persons selected to fill five of the six vacancies on the NPOAG ARC. Vacancies filled include the two commercial tour operator openings, the general aviation opening, the tribal opening, and one of the environmental openings. Since the previous notice did not draw enough responses from individuals for the remaining environmental vacancy, NPS and FAA are also using this notice to invite other interested individuals to apply for the remaining environmental opening. If you responded to the initial notice for the environmental openings, you will still be under consideration and need not re-apply.
