Boeing 787 pilots last week conducted the program’s first stall tests–in which pilots intentionally reduce power to both engines and then recover normal flight speeds–as part of the initial airworthiness program for the airplane. Additional stall tests will take place throughout the flight test period.
Jim Deuvall has written and published a handy primer on aircraft performance that can help pilots expand their understanding of how jets perform.
In 2008, the FAA issued new rules affecting pilots who fly the remaining fleet of more than 350 Mitsubishi MU-2 twin turboprops.
Socata TBM700, Kennesaw, Ga., July 15, 2008–The NTSB attributed the fatal crash of the single-engine turboprop to the pilot’s failure to maintain airspeed during final approach, which resulted in an aerodynamic stall. The aircraft was destroyed and its pilot killed when it rolled inverted and collided with trees short of the runway at Cobb County-McCollum Field.
Vero Beach, Fla.-based Piper Aircraft said it is delaying first deliveries of the single-engine PiperJet from the fourth quarter of 2012 until the second quarter of 2013. To compensate for the delay, Piper favorably changed contract terms for PiperJet customers, including maintaining the price at $2.19 million and changing the CPI escalator date from Oct. 1, 2007, to the beginning of this month.
While no one at Boeing would dare admit to any level of satisfaction with the two-and-a-half years of delays to the 787-8, the program’s chief mechanic, Justin Hale, might be one of the few people within the company who can say it has helped make his job easier.
Coincidental to the early taste of winter weather the Northeast received in mid-October, NBAA–in conjunction with local airport user groups and state business aviation associations–sponsored a pair of cold-weather operational seminars aimed at exploring the challenges and threats presented by in-flight and ground icing, as well as runway contamination.
• In January 2006, two pilots flying an American Eagle Saab 340 out of San Luis County Regional Airport in San Luis Obispo, Calif., nearly lost control after the autopilot shut off during icing conditions on climb-out. The Saab 340 lost 5,000 feet during the recovery.
Ever since the crash of American Eagle Flight 4184 (an ATR 72) in Roselawn, Ind., on Oct. 31, 1994, the NTSB has been recommending that the FAA enact a new rule that the Board believes might have prevented these accidents. As a result of the crash of Flight 4184, the NTSB recommended that the FAA “prohibit the use of the autopilot” during encounters with icing conditions.
Safe Flight Instrument (Booth No. 5130) has been selected to provide the speed-control system for Quest’s Kodiak turbine single.
