What Happened
On January 8, 2003, Air Midwest Flight 5481, a Beechcraft 1900D registered N233YV, crashed shortly after departing runway 18R at Charlotte-Douglas International Airport in North Carolina. The two pilots and 19 passengers were killed. One person on the ground sustained minor injuries. The airplane struck a maintenance hangar and was destroyed by impact and fire.
The scheduled US Airways Express flight was headed to Greenville-Spartanburg International Airport in South Carolina. Conditions at Charlotte were visual, although the flight operated on an instrument flight rules flight plan. The difficulty developed during takeoff, before weather or an instrument approach became a factor.
The airplane had flown multiple legs the previous day. The accident pilots had operated six of those legs, and another crew flew it to Lynchburg that evening and back to Charlotte the next morning. The returning crew reported no unusual behavior. That history gave the flight crew an airplane that had recently completed ordinary service, but it did not establish that its elevator travel or loading was safe for this departure.
Before leaving the gate, the pilots completed the weight-and-balance paperwork. A ramp agent reported 23 checked bags and eight carry-on bags. Two checked bags were estimated at 70 to 80 pounds each. The agent said he told the captain some bags were heavy, and that she indicated a child on board allowed room for the additional weight. These were the agent’s recollections, not measured weights for every bag.
At about 8:35 a.m., the crew checked the flight controls. The recorded control-column movement corresponded to full nose-up elevator but only 7 degrees of nose-down elevator. The airplane taxied to runway 18R and received takeoff clearance at about 8:46:18. The captain flew; the first officer set the takeoff power.
During acceleration, the elevator was at the recorded nose-down limit. The pitch attitude then began increasing, and the trim moved in the nose-down direction. The captain called for the landing gear to come up. By about 8:47:03, at roughly 90 feet above the ground, the airplane was pitched 20 degrees nose up and traveling at 139 knots. Both pilots were now trying to bring the nose down.
The crew applied forceful nose-down commands. The airplane continued pitching up, reaching 54 degrees nose up at about 8:47:13. A sound consistent with the stall warning appeared on the cockpit recording. The captain transmitted an emergency call, but the aircraft was already moving through a rapidly changing combination of pitch, bank, and airspeed.
At about 8:47:19, the airplane was roughly 1,150 feet above the ground. The recorder showed a left roll reaching 127 degrees and an airspeed as low as 31 knots. The nose then dropped steeply. Control inputs changed as the crew attempted to recover, but the remaining sequence lasted only seconds. The recording ended at about 8:47:28, with the airplane descending nose down and banked right.
Investigation Findings
The NTSB found two problems acting together: the elevator system had been rigged incorrectly, and the airplane’s center of gravity was substantially aft of its certified limit. The result was a loss of pitch control during takeoff.
The flight-control check is an important part of the evidence. The crew moved the controls, but the elevator did not have its intended nose-down authority. A control column moving through a range did not mean the elevator was moving through the correct range. The recorded positions connected the cockpit input to the limited control-surface response.
The aft center of gravity compounded that reduced authority. The loading condition increased the challenge of controlling pitch at the same time that the elevator system could not provide the proper nose-down response. Describing the accident as only a loading error or only a maintenance error would omit half of the mechanism identified by the Board.
The recorder also separated pilot intention from aircraft response. At about 90 feet above the ground, the pilots were forcefully commanding nose-down movement. The continued pitch increase did not mean they had chosen to climb at that attitude. Their commands and the airplane’s motion were moving in different directions.
Earlier uneventful flights did not disprove the defect. They showed that the airplane had flown with previous crews and loading conditions without a reported problem. The accident flight brought together the restricted elevator travel and an aft loading condition in a way that exceeded the available pitch-control margin.
The Board identified organizational contributors across maintenance and loading. Air Midwest’s oversight of work at Huntington, its maintenance procedures and documentation, and its weight-and-balance program all contributed. The quality-assurance inspector did not detect the incorrect elevator rigging. FAA average-weight assumptions and FAA oversight of the airline’s maintenance and weight-and-balance programs were also included.
Those findings place the maintenance release, inspection process, and loading calculation in the same accident chain. None was merely background information. Together, they determined whether the crew received an airplane whose controls and balance would let it respond normally during takeoff.
NTSB Probable Cause
the airplane’s loss of pitch control during take-off. The loss of pitch control resulted from the incorrect rigging of the elevator system compounded by the airplane’s aft center of gravity, which was substaintially aft of the certified aft limit.
Contributing to the cause of the accident were (1) Air Midwest’s lack of oversight of the work being performed at the Huntington, West Virginia, maintenance station; (2) Air Midwest’s maintenance procedures and documentation; (3) Air Midwest’s weight and balance program at the time of the accident; (4) the Raytheon Aerospace quality assurance inspector’s failure to detect the incorrect rigging of the elevator control system; (5) the Federal Aviation Administration’s (FAA) average weight assumptions in its weight and balance program guidance at the time of the accident; and (6) the FAA’s lack of oversight of Air Midwest’s maintenance program and its weight and balance program.
Safety Lessons
The maintenance lesson is to verify the actual control-surface travel after rigging work using the applicable maintenance procedure. Cockpit movement, a successful previous flight, and a general impression that the airplane flew well are different kinds of evidence. They cannot replace a required dimensional or travel check.
The loading lesson is to treat weight and balance as a control issue. The center-of-gravity limit is part of the airplane’s demonstrated handling envelope. A calculation is only as reliable as the loading information and assumptions behind it, and unusual baggage needs to be handled through the approved loading process rather than informal offsets.
For flight departments and operators, the case supports independent checks that can catch a common mistake before it reaches a takeoff. Maintenance oversight, required inspections, and a dependable loading program protect the same flight from different directions. The cockpit crew should not have to discover the combined failure of those barriers just above the runway.

Frequently Asked Questions
Q: Why did Air Midwest Flight 5481 pitch up after takeoff?
A: The NTSB found that incorrect elevator rigging limited pitch control and that the airplane’s center of gravity was substantially aft of its certified limit. The two conditions combined during takeoff.
Q: Did the Flight 5481 pilots try to lower the nose?
A: Yes. Recorded data showed forceful nose-down commands while the airplane continued pitching upward. The aircraft reached a recorded 54-degree nose-up attitude.
Q: Where did Air Midwest Flight 5481 crash?
A: The Beechcraft 1900D crashed on Charlotte-Douglas International Airport property after departing runway 18R on January 8, 2003. All 21 people aboard died.
