A 32-year-old advisory circular still used as the basis for showing compliance with in-flight icing protection rules is currently undergoing an “extensive” revision, and the FAA has published a draft version of it for comments. The objective of the revision, said the agency, is to provide a “uniform and modern” means of compliance with regulations for ice-protection requirements.
Weather satellites equipped to detect emergency locator transmitters helped rescue an estimated 1,500 sailors, hikers, downed pilots and others around the world last year, according to the National Oceanic and Atmospheric Administration. Its satellites, along with Russia’s Cospas satellites, form an international search-and-rescue system. NOAA said the 171 U.S.
CESSNA CARAVAN 208B, ROCKFORD, ILL., DEC. 17, 2002–At 10:51 p.m., Caravan N277PM crashed while on the ILS approach to Runway 7 at the Greater Rockford Airport (RFD). The pilot was killed and the airplane was destroyed. The Part 135 nonscheduled flight, operated by Planemasters as Flight 1627, was transporting cargo for UPS and was operating in IMC on an IFR flight plan, from Decatur Airport (DEC), Ill.
As I prepared to write this column the television and radio news programs were reporting on the recent spate of business aviation accidents. One of the widely reported accidents that caused considerable concern at the NTSB was the November 28 crash of the Challenger 601 in Montrose, Colo. In this accident the NTSB is investigating airplane performance issues, including the possibility of upper-surface wing ice contamination.
Cessna 208B Grand Caravan, Naches, Wash., Oct. 7, 2007–The commercial pilot and nine passengers died when the Caravan crashed in the mountains near Naches, at 7:59 p.m. No flight plan was filed for the flight from Star, Idaho, to Shelton, Wash., and the pilot did not obtain a weather briefing. There was an airmet for icing, low-level turbulence and mountain obscuration.
MITSUBISHI MU-2, LEWISTON, IDAHO, FEB. 11, 2000–“The pilot failed to follow the flight manual procedures and did not engage the continuous ignition system, resulting in both engines flaming out when ice blocked the air induction system.
KING AIR B-200, PIQUA, OHIO, AUG. 24, 2001–The chief pilot for the Hartzell Propeller Co. waited for a chartered King Air to shoot the approach into the Piqua Airport after the turboprop circled while waiting for fog to dissipate. As he heard the airplane on final approach, the Hartzell pilot heard the “terrible sound of impact” followed by silence. The King Air’s ATP-rated pilot died in the crash.
Mitsubishi MU-2B-40, Bunnell, Fla., Aug. 25, 2006–The NTSB determined that the crash of the MU-2 resulted from an inadvertent encounter with thunderstorms. The commercial pilot, cruising at FL280, had received a sigmet about convective activity. His onboard weather radar was working, and Jacksonville Center was equipped with Nexrad-derived weather displays, which indicated weak to moderate echoes above FL240.
The National Weather Service has awarded a team led by L-3 Enterprise IT Solutions a $43 million contract to upgrade Nexrad radar sites. Consisting of 171 weather radars positioned across the U.S. and a handful overseas, the sites collect data on local weather phenomena, which are then used to predict convective activity.
