Beschrijving:
Air Midwest flight 5481, a Beechcraft 1900D, crashed shortly after takeoff from runway 18R at Charlotte-Douglas International Airport (CLT, North Carolina, USA. The 21 occupants aboard the
airplane were killed.
The accident airplane had undergone a detail six (D6) maintenance check between the night of January 6 and the morning of January 7, 2003. During this check the elevator cable tension was adjusted.
In the process the elevator control system was incorrectly rigged, restricted the airplanes elevator travel to 7 airplane nose down, or about one-half of the normal downward travel. This error was not detected prior to release to service.
The airplane returned to service on the morning of January 7 and flew a total of nine flight legs before the accident flight.
At 08:37 the aircraft was ready for taxi for a flight to Greenville-Spartanburg Airport, South Carolina, USA. At 08:46 the flight was cleared for takeoff from runway 18R. One minute later, immediately after the landing gear had been retracted, the nose pitched up to 20. Both crew members reacted with surprise and the captain asked the first officer to help him.
Both flight crew then attempted forcefully push the nose down. The nose continued to pitch up to 54 and the stall warning horn sounded. The aircraft's nose dropped and it rolled 127 to the left.
The airplanes roll attitude then stabilized at about 20 left wing down; the pitch attitude began to increase. About 08:47:24 the airplane rolled right through wings level, and the pitch attitude increased to about -5. The nose dropped again and the airplane struck a US Airways maintenance hangar and came to rest about 1650 feet east of the runway 18R centerline and about 7600 feet beyond the runway 18R threshold.

It appeared that, aside from the limit nose down elevator travel, the aircraft had an excessive aft center of gravity due to substantially inaccurate weight and balance calculations.

Probable Cause:

PROBABLE CAUSE: "The airplanes loss of pitch control during takeoff. The loss of pitch control resulted from the incorrect rigging of the elevator control system compounded by the airplanes aft center of gravity, which was substantially aft of the certified aft limit. Contributing to the cause of the accident was: (1) Air Midwests lack of oversight of the work being performed at the Huntington, West Virginia, maintenance station; (2) Air Midwests maintenance procedures and documentation; (3) Air Midwests weight and balance program at the time of the accident; (4) the Raytheon Aerospace quality assurance inspectors failure to detect the incorrect rigging of the elevator system; (5) the FAAs average weight assumptions in its weight and balance program guidance at the time of the accident; and (6) the FAAs lack of oversight of Air Midwests maintenance program and its weight and balance program."

Veiligheidsmaatregelen
On January 27, 2003 the FAA issued Notice N8400.40 requiring a number of operators of 10 to 19 passenger seat aircraft to validate the Weight and Balance Control Program to sample passenger weights, carry-on baggage weights, and checked baggage weights for part of their flights.
The survey showed that the average passenger weight was higher than the estimates by 20.63 pounds, carry-on bags were higher by 5.72 pounds and domestic checked bags by 3.81 pounds. Consequently, on May 12, the FAA reported it is adding 10 pounds to its estimate for passengers and five pounds to luggage (Notice 8300.112). This notice was cancelled by the publication of AC 120-27D August 11, 2004.
