Revisions to Digital Flight Data Recorder Regulations for Boeing 737 Airplanes and for All Part 125 Airplanes
The FAA amends the regulations governing flight data recorders to increase the number of digital flight data recorder parameters for all Boeing 737 series airplanes manufactured after August 18, 2000. This change is based on safety recommendations from the National Transportation Safety Board following its investigations of two accidents and several incidents involving 737s. The rule also adopts a prohibition on deviations from flight recorder requirements for all airplanes operated under part 125.
Airworthiness Directives; Rolls-Royce plc RB211 Trent 500 Series Turbofan Engines
We are adopting a new airworthiness directive (AD) for the products listed above. This 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. The MCAI describes the unsafe condition as:
Air Traffic Procedures Advisory Committee
The FAA is issuing this notice to advise the public that a meeting of the Federal Aviation Administration Air Traffic Procedures Advisory Committee (ATPAC) will be held to review present air traffic control procedures and practices for standardization, revision, clarification, and upgrading of terminology and procedures.
Special Conditions: Spectrum Aeronautical, LLC Model 40; Lithium Polymer Battery Installation
This action proposes special conditions for the Spectrum Aeronautical, LLC Model 40 (S-40) airplane. This airplane will have a novel or unusual design feature associated with the installation of lithium polymer (Li-Poly) batteries for emergency, main, and auxiliary power unit (APU) applications. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; MD Helicopters, Inc. Model MD900 Helicopters
This document supersedes AD 2008-18-52 and publishes in the Federal Register an amendment adopting Emergency Airworthiness Directive (AD) 2008-22-53 which was sent previously to all known U.S. owners and operators of MD Helicopters, Inc. (MDHI) Model MD900 helicopters by individual letters. This AD requires turning ON both Vertical Stabilizer Control System (VSCS) switches and turning OFF the autopilot (AP/SAS) switch; pulling certain AP/SAS circuit breakers; installing a placard near the AP/SAS master switch; installing an airspeed limitation placard on the instrument panel; and making changes to the Rotorcraft Flight Manual (RFM). This AD is prompted by 4 occurrences in which the left VSCS adapter tubes failed on the MD900 helicopters and the vertical stabilizer became uncontrollable, resulting in reduced yaw control of the helicopter. There were no injuries, but in one occurrence, due to the high speed quick yaw, the helicopter lost a window and a door. The actions specified by this AD are intended to prevent loss of yaw control and subsequent loss of control of the helicopter.
Airworthiness Directives; Boeing Model 777-200LR Series Airplanes Powered by General Electric (GE) Model GE90-110B Engines, and Model 777-300ER Series Airplanes Powered by GE Model GE90-115B Engines
We are revising an existing airworthiness directive (AD) that applies to certain Boeing Model 777-200LR and -300ER series airplanes. That AD currently requires revising the airplane flight manual to prohibit takeoffs at less than full-rated thrust. This new AD reduces the applicability of the existing AD. This AD results from a report of two occurrences of engine thrust rollback during takeoff. We are issuing this AD to prevent dual-engine thrust rollback during the takeoff phase of flight, which could result in the airplane failing to lift off before reaching the end of the runway or failing to clear obstacles below the takeoff flight path.
Notice of Passenger Facility Charge (PFC) Approvals and Disapprovals
The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub. L. 101-508) and Part 158 of the Federal Aviation Regulations (14 CFR part 158). This notice is published pursuant to paragraph d of Sec. 158.29.
