Ruidoso-Sierra Blanca

The commercial pilot had filed an instrument flight rules flight plan and was departing in dark night visual meteorological conditions on a cross-country personal flight. A witness at the departure airport stated that during takeoff, the airplane sounded and looked normal. The witness said that the airplane lifted off about halfway down runway 24, and there was "plenty" of runway remaining for the airplane to land. The witness lost sight of the airplane and did not see the accident because the airport hangars blocked her view. The wreckage was located about 2,400 ft southeast of the departure end of runway 24. Examination of the accident site indicated that the airplane impacted in a nose-down attitude with a left bank of about 20°. A left turn during departure was consistent with the airport's published instrument departure procedures for obstacle avoidance, which required an immediate climbing left turn while proceeding to a navigational beacon located about 7 miles east-northeast of the airport. Examination of the wreckage did not reveal any evidence of preimpact mechanical malfunctions that would have precluded normal operation. The pilot had reportedly been awake for about 15 hours and was conducting the departure about the time he normally went to sleep and, therefore, may have been fatigued about the time of the event; however, given the available evidence, it was impossible to determine the role of fatigue in this event. Although the circumstances of the accident are consistent with spatial disorientation, there was insufficient evidence to determine whether it may have played a role in the sequence of events.

The pilot departed on runway 06 with zero degrees of flaps. A witness said that she noticed that the airplane appeared to wobble and shudder, and immediately went into a steep right bank turn right after takeoff. The airplane then went into the clouds which were 200 to 400 feet agl. Radar data indicated that the airplane made several 90 degree turns prior to impacting the mountainous terrain 2.55 nm from the departure end of the runway. The pilot normally used 20 degrees of flaps for takeoff. A test pilot said that the airplane handles significantly different during takeoff if zero degrees of flaps are used verses 20 degrees of flaps. The upper cabin's entry door was found, with the locking handle and locking pins, in the closed position. No preimpact engine or airframe anomalies, which might have affected the airplane's performance, were identified.

While departing on a cross country flight the aircraft was observed to have an abnormally long takeoff roll and to rotate abruptly to a higher than normal nose attitude. Initial climb was followed by settling with a high nose attitude and the aircraft crashed approximately one mile beyond the departure end of the runway. The main cabin door was found in the unlocked position and the lower half was found near the beginning of the wreckage path with impact damage. The top half was found further down the wreckage path and had sustained fire damage. The Aerostar has an observed drag and pitch performance degradation if the cabin door opens during takeoff run. A passenger was seriously injured while two other occupants were killed.

Shortly after takeoff from Ruidoso-Sierra Blanca Regional Airport in nil visibility, the twin engine airplane struck trees and crashed in flames. The wreckage was found a day later and both occupants were killed.
