Federal Aviation Administration October 24, 2006 – Federal Register Recent Federal Regulation Documents

Pursuant to FAA's rulemaking provisions governing the application, processing, and disposition of petitions for exemption, part 11 of Title 14, Code of Federal Regulations (14 CFR), this notice contains a summary of certain petitions 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 the 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.

This document makes a correction to the final regulation published in the Federal Register on June 21, 2006. (71 FR 35760) This rule amended the airman medical certification standards to disqualify an airman based on an alcohol test result of 0.04 or greater breath alcohol concentration (BAC) or a refusal to take a drug or alcohol test required by the Department of Transportation (DOT) or a DOT agency.

The FAA proposes to adopt a new airworthiness directive (AD) for GE CF6-80C2B series turbofan engines with electronic control units (ECUs), installed on Boeing 747 and 767 airplanes. This proposed AD would require installing software version 8.2.Q1 to the engine ECU, which increases the margin to engine flameout. This proposed AD results from reports of engine flameout events during flight, including reports of events where all engines simultaneously experienced a flameout or other adverse operation. We are proposing this AD to provide increased margin to flameout and to minimize the potential of an all-engine flameout event, due to ice accretion and shedding during flight.
