Raytheon A36 N88855 accident near San Marcos, Texas

Probable cause

The pilot’s loss of control shortly after takeoff in instrument meteorological conditions for reasons that could not be determined based on the available information.

NTSB analysis

The pilot filed an instrument flight rules flight plan for the cross-country flight and received a departure clearance. A witness reported seeing the accident airplane taxi by his hangar before it departed and noted that the visibility at the time was less than the 1/4-mile reported by the airport’s weather observation facility. The airplane departed and was seen on radar before contact was lost shortly thereafter; the pilot never established radio communication with air traffic control. The airplane impacted terrain in a near-vertical attitude about 1/2-mile from the departure runway. Examination of the airplane did not reveal any pre-impact anomalies that would have precluded normal operation. Low instrument flight rules conditions prevailed in the area of the departure airport, including a cloud ceiling of about 300 ft above ground level.

The airplane’s sudden descent and near-vertical impact attitude are consistent with a loss of control shortly after takeoff; however, due to a lack of onboard data and complete radar data for the flight, the reason for the loss of control could not be determined based on the available information.
