Department of Transportation January 6, 2010 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede an existing airworthiness directive (AD) for Rolls-Royce plc RB211-Trent 800 series turbofan engines. That AD currently requires replacing the fuel-to-oil heat exchanger (FOHE). This proposed AD would require replacing the FOHE on the RB211-Trent 500 and RB211-Trent 700 series turbofan engines in addition to the RB211-Trent 800 series turbofan engines. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product, and results from the risk of engine FOHE blockage. The MCAI describes the unsafe condition as:

This action amends Special Federal Aviation Regulation 106 (SFAR 106), Use of Certain Portable Oxygen Concentrator Devices on Board Aircraft, to allow for the use of four additional portable oxygen concentrator (POC) devices on board aircraft, provided certain conditions in the SFAR are met. This action is necessary to allow all POC devices deemed acceptable by the FAA to be available to the traveling public in need of oxygen therapy, for use in air commerce. When this rule becomes effective, there will be a total of 11 different POC devices the FAA finds acceptable for use on board aircraft, and passengers will be able to carry these devices on board the aircraft and use them with the approval of the aircraft operator.

The FAA invites public comments about our intention to request the Office of Management and Budget's (OMB) revision of a current information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on Information collected to provide services to aircraft inflight and protection of persons/property on the ground.
