Runway Departure Due to Loss of Control in Crosswind Conditions (N21677)

Palo Alto, CA, US

On March 10, 1990, a Piper J3 (registration N21677) operated by West Valley Flying Club was involved in an aviation accident near Palo Alto, CA. Investigators recorded the probable cause as: The pilot's failure to maintain directional control during landing due to wind conditions, which resulted in a runway departure. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 8 related events involving the same aircraft type or operator are linked below.

A pilot lost control of the aircraft during landing on runway 30 due to strong crosswinds, resulting in a departure from the paved surface and collision with terrain. No mechanical issues were reported.

What happened

The pilot was conducting a landing operation on runway 30 when the event occurred. At the time of touchdown, wind conditions were variable, with speeds ranging from 8 to 12 knots coming from directions between 230 and 280 degrees. These winds created significant crosswind components for the runway heading.

Upon contacting the runway, the pilot reported an immediate inability to maintain directional control of the aircraft. Despite active attempts to correct the trajectory and regain control, these efforts proved unsuccessful. The aircraft continued its path off the paved surface and collided with the surrounding terrain.

The investigation

Following the incident, the pilot provided a statement regarding the circumstances leading up to the collision. The pilot explicitly reported that there were no known mechanical malfunctions or problems with the aircraft prior to the impact. This indicates that the airframe and propulsion systems were operating within normal parameters at the time of the event.

Findings

The primary factor contributing to the accident was the loss of directional control during the landing roll. The environmental conditions, specifically the wind speed and direction relative to the runway alignment, exceeded the pilot's ability to keep the aircraft aligned with the runway centerline. The failure to maintain control resulted in the aircraft leaving the designated landing area.

Safety message

Landing operations in variable wind conditions require careful assessment of crosswind components. Pilots must ensure they are proficient in crosswind techniques and aware of their aircraft's limitations regarding gusty winds. Proper configuration and timely decision-making are critical to maintaining control during the most vulnerable phase of flight.

Probable cause

The pilot's failure to maintain directional control during landing due to wind conditions, which resulted in a runway departure.
