Aviation Accident Summary WPR10CA035

Angwin, CA, USA

Aircraft #1

N1721T

PIPER PA-28-140

Analysis

The pilot reported that he positioned the airplane for the night takeoff approximately 1/4-mile from the start of Runway 34. He attempted to activate the runway lights using the radio; however, he had selected an incorrect frequency. He used his landing light and positioned the airplane where he believed the runway was located. As the airplane approached 65 miles per hour, he saw grass and dirt. His passenger requested that he stop the airplane; however, the pilot felt that his options were better if he continued the takeoff. The passenger continued to request that he stop the airplane and the groundspeed was about 80 miles per hour. The pilot further reported that the passenger’s seat was positioned further back than his and that the passenger was pulling the yoke aft and her feet were pushing on the rudder pedals. The airplane then impacted a fence. Later activation of the airport lighting system revealed no operational anomalies when the correct radio frequency was selected.

Factual Information

The pilot reported that he positioned the airplane for the night time takeoff approximately 1/4-mile from the start of runway 34. He attempted to activate the runway lights using the radio; however, he had selected an incorrect frequency. He used his landing light and positioned the airplane where he believed the runway was located. As the airplane approached 65 miles per hour, he saw grass and dirt. His passenger requested that he stop the airplane but in his opinion, he felt his options were better if he continued the takeoff. The passenger continued to request that he stop the airplane and the groundspeed was about 80 miles per hour. The pilot further reported that the passenger’s seat was positioned farther back than his and that the passenger was pulling the yoke aft and her feet were pushing on the rudder pedals. The airplane then impacted a fence. Later activation of the airport lighting system revealed no operational anomalies when the correct radio frequency was selected.

Probable Cause and Findings

The pilot's failure to properly identify the runway surface for takeoff and his subsequent failure to abort the takeoff when he realized he was not on the runway. Contributing to the accident was the pilot’s failure to select the appropriate radio frequency to activate the runway lights.
