About three seconds later, the captain stated, "This thing ain't gonna...hold altitude. <<4349812783118A4AB642A9941A095D86>]>> 0000206109 00000 n At 9:32 p.m., the crew was level at 24,600 feet, when a third pitch up was recorded on the flight data recorder, which produced a rate of climb that briefly peaked at 9,000 feet per minute. The airspeed was now 150 knots, and the pitch was almost twice what it should have been. At 15,000 feet, approximately six minutes after takeoff, the crew initiated a second pitch up maneuver so severe that it produced a rate of climb of 10,000 feet per minute. 0000205403 00000 n 0000205821 00000 n
First discovered in the CF34 engines in 1983, a test profile was developed for new airplanes to fly to determine whether the engines were susceptible to core lock. 0000003801 00000 n If the pilot does not take the proper corrective action, or if the situation deteriorates, then a stick pusher activates. 0000204834 00000 n GE, the engine manufacturer, testified that as long as an airspeed of 240 knots was maintained, the core would continue to spin. 0000207041 00000 n 0000216079 00000 n 0000138365 00000 n 0000110444 00000 n 0000171263 00000 n 0000203623 00000 n 0000203865 00000 n 0000215209 00000 n 0000208182 00000 n 0000205982 00000 n 0000073917 00000 n 0000006790 00000 n 0000206261 00000 n 0000207591 00000 n It is common practice to expect — and demand — that pilots operate the equipment and the flights that are flown under Part 91 the same way they do under Part 121, even though there are no passengers on board.The crew of Flagship 3701, a Bombardier Canadair CRJ 200, did not, and they paid for it with their lives.The captain, age 31, was an airline transport pilot with 6,900 hours of total flying time, of which 5,055 hours were flown as a pilot in command. Another topic sparked some questions regarding the 2004 Pinnacle Airlines Flight 3701, the RJ that climbed to FL410. The stick pusher produces a strong, forward movement of the control column, with enough force to pry the control column from an unprepared pilot's hands. 0000217538 00000 n %PDF-1.6 %���� 0000207136 00000 n

At an altitude of only 190 feet agl, the crew initiated an extreme pitch up of the aircraft that peaked at 22 degrees of pitch; standard takeoffs in the Canadair Regional Jet 100/200 using the takeoff mode of the flight director are done at approximately 15 degrees of pitch. 0000205159 00000 n The airplane was on a repositioning flight3 from Little 0000006452 00000 n But every once in a great while, there is an event that can be discussed only using harsh criticism. A solid-state cockpit voice recorder (CVR) was sent to the National Transportation Safety Board™s Audio Laboratory for readout. 1476 171 In normal operations, the auxiliary power unit (APU), which also has a generator, is not used unless one engine generator is deferred.

In the event of an impending stall, a stick shaker activates. 0000209446 00000 n 0000214305 00000 n startxref Being in the wrong seats did not help, and the ADG, which is an extremely noisy distraction, probably made it difficult to hear.The double-engine failure checklist calls for an immediate airspeed of 240 knots, which provides a modicum of glide performance and also keeps the engines and the ADG propeller rotating. 0000206409 00000 n 0000007061 00000 n 0000170914 00000 n We're gonna be...coming down in a second here."

As far as foul language goes, that's not un-common in a flight deck. 0000205646 00000 n The crash of Pinnacle Airlines (call sign "Flagship" and now doing business as Northwest Airlink) flight 3701 on October 14, 2004, is such an example. In the event of an emergency, such a lack of common sense can snowball into a real problem. 0000213315 00000 n 0000212564 00000 n It is an attitude, an approach to your job, an adherence to procedures and protocols. During the climb, the airspeed had declined from 203 knots at 37,000 feet to only 163 knots at 41,000 feet. At this point, the airplane is trying to protect itself, doing what it can to prevent a full stall from developing.Only five seconds after rotation, the crew of Flagship 3701 made a control input that was severe enough to activate both the stick shaker and -pusher. I've encountered it a couple of times during various training sessions.
