The FAA last month released a final rule governing certification of transport-category (Part 25) airplanes for operation in icing conditions. The new rule, which takes effect October 9, effectively added new material to Part 25, Appendix C, the section that details the so-called icing envelope.
Mitsubishi MU-2B-35, Argyle, Fla., Sept. 1, 2006 – The NTSB determined the probable cause of the MU-2 accident to be the pilot’s inadvertent flight into thunderstorm activity that resulted in the loss of control, design limits of the airplane being exceeded and subsequent in-flight breakup.
The FAA yesterday released a final rule governing certification of transport-category (Part 25) airplanes for operation in icing conditions, effective October 9. In publishing the new rules, the FAA added new material to Part 25, Appendix C, the section that details the so-called icing envelope. The new Appendix C material, however, does not address the NTSB’s desire for the icing envelope to be expanded to include larger icing droplets.
A proposal to require California’s Santa Monica Municipal Airport (SMO) to measure jet taxi and idle times during a one-year period is dead, according to the National Air Transportation Association (NATA). “Assembly Bill 2501,” NATA said, “failed to gather enough votes for passage out of the California Senate Committee on Transportation and Housing.
While the debate continues to swirl on both sides of the Atlantic over the European Union’s scheduled imposition of a carbon dioxide (CO2) emissions trading program involving air travel, a new initiative to address the problem was launched in June at the Paris Air Show.
Swearingen SA-26AT, Jacksonville, Fla., Nov. 27, 2003 – The NTSB concluded that the commercial pilot of the SA-26 that crashed on an ILS approach to Craig Airport descended below decision height in low ceilings and fog. A factor was the pilot’s decision to attempt the instrument approach with weather below the prescribed minimums.
Jet Aviation Saarbrucken, Germany, recently performed extensive repairs on a Citation II that was heavily damaged by hail in just 15 seconds. The aircraft was on approach to Amsterdam Airport at an altitude of 10,000 feet when it encountered a hail storm. The aircraft, which was traveling at 250 knots, encountered hail stones “the size of tennis balls.”
NavAirWx has added live temporary flight restrictions (TFRs) to its moving-map and real-time weather display systems. The Mt. Kisco, N.Y., company uses satellite broadcast technology to provide “instantaneous access to current TFRs, with updates every 12 minutes.” Along with weather information updated on a five-minute cycle, “pilots now have complete and current conditions for every point along the route of flight,” according to NavAirWx.
Eurocopter AS 350B3, Yellow Pine, Idaho, Aug. 13, 2006–The NTSB determined that the U.S. Forest Service contract pilot’s intentional low-altitude flight and his failure to maintain an adequate altitude to clear the trees was the cause of the crash of the AS 350, which killed all four on board.
The FAA said last month that this summer it will greatly expand the airspace flow program (AFP), an initiative it implemented last summer to better manage airline delays associated with summer thunderstorms. In all, seven combinations were available for use last year, mainly to meter the flow of traffic to the Northeast. This year operators can expect 18 separate geographic possibilities when the program expands to the Midwest.
