NTSB Factual Report


On February 4, 2001, about 1218 central standard time, a Watson Steen Skybolt, N50BW, piloted by an airline transport pilot, was destroyed on impact with terrain while performing a low altitude maneuver near the pattern for runway 33 at Camdenton Memorial Airport (H21), near Camdenton, Missouri. The personal flight was operating under 14 CFR Part 91. Visual meteorological conditions prevailed at the time of the accident. No flight plan was on file. The pilot and passenger were fatally injured. The flight departed from Carrollton Memorial Airport, near Carrollton, Missouri, at time unknown, and was destined for H21.

A witness stated:

Aircraft made a pass down runway 15 (clearing pass) and started a

climbing turn to right and I assumed he would make a left base for

runway 33. I rushed to finish what I was doing as I was waiting for

him. My next awareness was he had crashed - [the airport manager]

came and told me. The wind at the time was 260 degrees at 9 knots

gusting to 17 knots. With these conditions there are very bad wind

shear conditions from about end of 33 for about 1 mile south up to

about 400 feet. Doing landings with students I have had up to 200

feet altitude loss and a loss of 10 to 15 knots indicated airspeed. This

always occures with westerly winds 10 knots or greater.

Another witness stated:

On Sunday, 02/04/01, at approximately 12:00 to 12:20 hrs I was

sitting in the parking lot of Speedline Technologies on S. Hwy 5. I

observed a white double winged airplane coming from the north and

appeared to be taking off from the runway of the Camdenton Memorial

Airport. As the plane traveled southbound and gained altitude, it rolled

over once doing a 'Barrel Roll'. Immediately after that the nose of the

plane went up into the air and then looped back over it's self doing a

'loop-d-loop'. It appeared that the plane then went nose first into the

tree line where I lost sight of it. I contacted Camden County Sheriff's

Department Dispatch and advised them that there was a possible plane

crash at the airport, but I was not sure as to where it was. At that time

myself and [a witness] drove down county Rd. 5-120 trying to locate

that crash. Unable to see it from the road, we then started walking

towards the runway. ... I observed the plane that I had seen flying

earlier on the ground just off the asphalt and facing towards the north.


The pilot was an airline transport pilot. He held a Third Class Medical Certificate dated April 20, 2000. On his application for that medical certificate, he listed his total pilot time to date as 25,678 hours and 20 hours in the past six months. That application did not show any visits to health professionals within the last three years. That application asked, "Do You Currently Use Any Medication (Prescription or Nonprescription)?" The answer "No" was checked for that question.

The pilot's medical records were reviewed. The records showed that the pilot visited a doctor on June 23, 1999. The records stated that the pilot complained "of depression with significant rage." His treatment plan included a "prescription for CELEXA." These records did not show that the patient was a pilot.


The airplane was a Watson Steen Skybolt, serial number W-001. The airplane's special airworthiness certificate was issued on May 12, 1994. The last found annual condition inspection was dated June 22, 1999. The tachometer entry at that condition inspection was 435 hours. The tachometer read 488.44 hours on-scene.


At 1215, the Lee C. Fine Memorial Airport, near Kaiser Lake Ozark, Missouri, weather was: Wind 320 degrees at 9 knots gusting to 17 knots, variable from 260 degrees to 010 degrees; visibility 10 statute miles; sky condition broken 3,600 feet; temperature 7 degrees C; dew point -2 degrees C; altimeter 30.08 inches of mercury.


The airplane was found approximately 28 feet east of runway 33's taxiway and approximately 424 feet north of the beginning of that taxiway's pavement. The airplane's heading was approximately 320 degrees and its directional gyro was found indicating 340 degrees. The airplane was found with its propeller impacted approximately two feet down into terrain. The terrain was found to be soft and it contained various sized rocks. The terrain rose in elevation on the side of the airplane's left wing. The upper wing was crushed downward. The engine was found under the airplane's upper wing. Both main landing gear were found crushed rearward and outward. The lower engine cowl was crushed upward and rearward. The empennage was found twisted, downward and to the right, aft of the rear seat. Both propeller blade backs exhibited chordwise scratches and their leading edges contained nicks. (See appended photographs)

An on scene investigation was performed. Continuity was established to the flight control surfaces. Control continuity was established to the engine. The engine produced a thumb compression and suction at all cylinders and valve train continuity was confirmed. A blue liquid was found in the fuel servo. The magnetos were found to produce spark to 11 of 12 leads. No anomalies were found.


The Boone/Callaway County Medical Examiners Office performed an autopsy on the pilot on February 6, 2001.

The Federal Aviation Administration (FAA) Civil Aeromedical Institute prepared a Final Forensic Toxicology Accident Report. The report indicated:

0.314 (ug/ml, ug/g) CITALOPRAM detected in Blood

CITALOPRAM present in Liver

0.157 ug/mL, ug/g N-DESMETHYCITALOPRAM detected in Blood


0.011 ug/mL, ug/g DI-N-DESMETHYCITALOPRAM detected in Blood

0.65 ug/mL, ug/g DI-N-DESMETHYCITALOPRAM detected in Liver


The parties to the investigation included the FAA and Textron Lycoming.

The aircraft wreckage was released to a representative for Universal Loss Management insurance.

NTSB Probable Cause

The pilot not maintaining altitude/clearance from terrain during the low altitude maneuver. Factors were the wind gusts and the low altitude maneuver the pilot performed.
