Total fatalities:
55
Circumstances:
Shortly after takeoff from runway 13 at Baotou Airport, while in initial climb, the aircraft encountered difficulties to maintain a positive rate of climb. It stalled, collided with a small house and eventually crashed in the icy lake of the Nanhai Park. The wreckage was found about 2 km from the airport and all 53 occupants were killed as well as two people in the house.
Probable cause:
Loss of lift and subsequent stall after takeoff due to an excessive accumulation of ice and frost on wings, tail and fuselage. It was determined that the aircraft remained parked outside, on the ramp, all preceding night by negative temperature and that the crew failed to deice the airplane prior to takeoff.

Circumstances:
On October 14, 2004, about 2215:06 central daylight time, Pinnacle Airlines flight 3701 (doing business as Northwest Airlink), a Bombardier CL-600-2B19, N8396A, crashed into a residential area about 2.5 miles south of Jefferson City Memorial Airport, Jefferson City, Missouri. The airplane was on a repositioning flight from Little Rock National Airport, Little Rock, Arkansas, to Minneapolis-St. Paul International Airport, Minneapolis, Minnesota. During the flight, both engines flamed out after a pilot-induced aerodynamic stall and were unable to be restarted. The captain and the first officer were killed, and the airplane was destroyed. No one on the ground was injured.
Probable cause:
The National Transportation Safety Board determines that the probable causes of this accident were:
1) the pilots' unprofessional behavior, deviation from standard operating procedures, and poor airmanship, which resulted in an in-flight emergency from which they were unable to recover, in part because of the pilots' inadequate training;
2) the pilots' failure to prepare for an emergency landing in a timely manner, including communicating with air traffic controllers immediately after the emergency about the loss of both engines and the availability of landing sites; and
3) the pilots' failure to achieve and maintain the target airspeed in the double engine failure checklist, which caused the engine cores to stop rotating and resulted in the core lock engine condition.
Contributing to this accident were:
1) the engine core lock condition, which prevented at least one engine from being restarted, and
2) the airplane flight manuals that did not communicate to pilots the importance of maintaining a minimum airspeed to keep the engine cores rotating.
