Petition for Exemption; Summary of Petition Received
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.
Airworthiness Directives; Bell Helicopter Textron Canada Models 206L, L-1, L-3, L-4, and 407 Helicopters
We propose to adopt a new airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (BHTC) helicopters. 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 Aviation Authority of Canada with whom we have a bilateral agreement states in the MCAI:
Airworthiness Directives; McDonnell Douglas Model DC-10-10 and DC-10-10F Airplanes, Model DC-10-15 Airplanes, Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) Airplanes, Model DC-10-40 and DC-10-40F Airplanes, Model MD-10-10F and MD-10-30F Airplanes, and Model MD-11 and MD-11F Airplanes
We are revising an earlier proposed airworthiness directive (AD) for certain transport category airplanes identified above. The original NPRM would have required modifying the fuel boost pumps. The original NPRM resulted from a fuel boost pump found with blown thermal fuses and a fractured thrust washer. This action revises the original NPRM by referring to new service information, which would require more work. We are proposing this supplemental NPRM to prevent failure of the fuel boost pumps, which could lead to the potential of ignition sources inside fuel tanks. This condition, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Agusta S.p.A. Model AB 139 and AW 139 Helicopters
We propose to adopt a new airworthiness directive (AD) for Agusta S.p.A. Model AB 139 and AW 139 helicopters. 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 European Aviation Safety Agency (EASA), the Technical Agent for Italy, with which we have a bilateral agreement, states in the MCAI:
Revisions to Cockpit Voice Recorder and Digital Flight Data Recorder Regulations
This final rule amends cockpit voice recorder (CVR) and digital flight data recorder (DFDR) regulations affecting certain air carriers, operators, and aircraft manufacturers. This final rule increases the duration of certain CVR recordings, increases the data recording rate for certain DFDR parameters, requires physical separation of the DFDR and CVR, improves the reliability of the power supplies to both the CVR and DFDR, and requires that certain datalink communications received on an aircraft be recorded if datalink communication equipment is installed. This final rule is based on recommendations issued by the National Transportation Safety Board following its investigations of several accidents and incidents, and includes other revisions the FAA has determined are necessary. These changes to CVR and DFDR systems are intended to improve the quality and quantity of information recorded, and increase the potential for retaining important information needed for accident and incident investigations.
