The NTSB today released the preliminary report for last Tuesday’s fatal crash of the Spectrum 33 prototype. According to the Safety Board, witnesses said the airplane entered a right roll almost immediately after takeoff from Spanish Fork Airport, Utah. The roll continued to about 90 degrees right wing down when the right wingtip hit the ground.
On Monday, the FAA issued a proposed Airworthiness Directive that would mandate a one-time 80-manhour detailed inspection of the flight-control systems on Raytheon Beechcraft King Air C90A, B200, B200C, B300 and B300C turboprops. The proposed AD is the result of a report of "nonconformities" by an FAA Manufacturing Inspection District Office.
Raytheon Aircraft said it is working with the FAA, NTSB, Transport Canada and Pratt & Whitney Canada to determine the root cause of three Beechjet dual engine flameouts in less than two years (see "Third dual flameout raises questions about Beechjet," AINonline).
The FAA had planned to deliver Operations Specifications C082 on calculating new landing-distance safety margins by June 30, but it is still in a draft version.
A Falcon 900 (N699BG) owned and operated by Erg Aviation II overran Runway 1 during landing at Greenville Downtown Airport, S.C., on July 17, but was stopped by the Engineered Materials Arresting System (EMAS), preventing possible injuries and damage. The pilot told the NTSB that during the approach the anti-skid system had to be tested twice to produce the correct indication.
NBAA and the National Air Transportation Association (NATA) expressed concern about the FAA’s June notice requiring the addition of a 15-percent landing-distance safety margin. NBAA and NATA believe that the FAA is bypassing the normal regulatory process.
The FAA is expected to push back “a few weeks” the implementation dates for the 15-percent runway safety margin requirement. A four-week delay, for example, would require air carriers to submit compliance procedures to their POI by October 1, with implementation required by November 1.
The NTSB on Friday released to the FAA its formal recommendations (A-06-42 and A-06-43) resulting from its investigation into the fatal crash of a Challenger 600 during takeoff from Montrose, Colo., on Nov. 28, 2004.
In the last 10 years, business aviation safety has improved dramatically. During this period, the entire industry has been the subject of numerous equipment and procedural requirements intended to reduce accidents. But have these requirements indeed improved safety or were they just financial, maintenance and procedural headaches for the thousands of operators who were forced to comply?
In the aftermath of four dual flameouts involving P&WC JT15D-powered Beechjets, the NTSB on Friday issued an urgent recommendation to help prevent further incidents on Beechjets and a broader recommendation calling on the FAA to work with engine and airplane OEMs to develop an ice detector for new engines, as well as for retrofit.
