Casualties unknown

Aircraft crashes shortly after takeoff from Morgan Airport due to turbulence and downdraft (N3809P)

Morgan, UT, US

On April 3, 1987, a Piper PA-22-150 (registration N3809P) operated by John D. Compton was involved in an aviation accident near Morgan, UT. Investigators recorded the probable cause as: The pilot's inability to maintain altitude and airspeed due to moderate turbulence and a downdraft while operating near gross weight. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft departed Morgan Airport near gross weight in strong crosswinds, encountered moderate turbulence and a downdraft, and impacted the ground shortly after reaching 100 feet AGL.

What happened

The pilot departed from Morgan Airport with an aircraft that was loaded near its maximum gross weight. The departure occurred under conditions featuring relatively strong crosswinds. Following a successful initial climb, the aircraft reached approximately 100 feet above ground level (AGL). Shortly thereafter, the pilot reported encountering moderate turbulence accompanied by a downdraft. These atmospheric conditions made it impossible to maintain the desired altitude and airspeed. Consequently, the aircraft impacted the ground in close proximity to the departure end of Runway 21.

The investigation

The available source material does not provide specific details regarding mechanical examinations or post-accident forensic findings. The narrative focuses exclusively on the operational sequence and environmental conditions observed during the flight phase leading up to the impact.

Findings

Several critical factors contributed to the accident. The aircraft was operating near its gross weight limit, which can significantly degrade climb performance and stall margins. Additionally, the presence of a relatively strong crosswind at departure likely increased the workload on the pilot and affected the aircraft's handling characteristics. The encounter with moderate turbulence and a downdraft immediately after takeoff removed the margin for error. The inability to maintain altitude and airspeed in these conditions led directly to the loss of control and subsequent impact with the terrain.

Safety message

Pilots must carefully calculate weight and balance before flight, especially during takeoff operations. Operating near maximum gross weight reduces climb performance and resilience against adverse weather. Awareness of wind shear, turbulence, and downdrafts is essential for maintaining safe flight paths during the critical initial climb phase.

Probable cause

The pilot's inability to maintain altitude and airspeed due to moderate turbulence and a downdraft while operating near gross weight.
