Student Pilot Crash During Takeoff Due to Fatigue and Crosswind (N6509L)

Snohomish, WA, US

On July 28, 1986, a Cessna 152 (registration N6509L) was involved in an aviation accident near Snohomish, WA. Investigators recorded the probable cause as: The pilot's premature rotation during takeoff due to fatigue and lack of experience, resulting in a loss of control off the runway.

A student pilot with minimal solo experience attempted takeoff in a quartering tailwind. Fatigue and premature rotation led to a leftward veer off the runway onto uneven terrain.

What happened

The accident occurred during the takeoff phase of flight when a student pilot was attempting to depart from the airport. The prevailing weather conditions included a quartering tailwind, which presented significant handling challenges for an inexperienced aviator. As the aircraft accelerated down the runway, it began to veer noticeably to the left of the centerline. Recognizing the deviation, the pilot attempted to correct by rotating prematurely before reaching the appropriate airspeed or rotation speed.

This early rotation caused the aircraft to lose forward momentum and settle back onto the ground. Instead of clearing the runway environment, the aircraft drifted further to the left, leaving the paved surface entirely. It impacted uneven terrain adjacent to the runway, resulting in substantial damage to the airframe. The pilot's lack of experience was a critical factor; at the time of the accident, he had accumulated less than one hour of solo flight time.

The investigation

Examination of the circumstances revealed that the pilot was suffering from fatigue during the operation. This physical state likely impaired his decision-making and reaction times. The combination of inadequate solo experience and a challenging wind condition contributed to the loss of control during the critical takeoff roll. The premature rotation was identified as the immediate mechanical cause of the ground impact.

Findings

The primary contributing factors to this accident were the pilot's fatigue and his limited flight experience. The attempt to depart in a quartering tailwind without sufficient skill or awareness exacerbated the situation. The decision to rotate early, rather than continuing the takeoff roll to achieve proper speed, directly led to the aircraft settling back onto the ground off the runway.

Safety message

Pilots must ensure they are well-rested before flight operations. Student pilots should be particularly cautious when operating in crosswind or tailwind conditions and must adhere strictly to recommended rotation speeds rather than attempting early liftoffs.

Probable cause

The pilot's premature rotation during takeoff due to fatigue and lack of experience, resulting in a loss of control off the runway.
