Glider Pilot Disoriented After Tow Release Lands on Ultralight Strip (N3204F)

EL Mirage, AZ, US

On May 18, 1984, a Let L-13 (registration N3204F) was involved in an aviation accident near EL Mirage, AZ. Investigators recorded the probable cause as: The pilot's loss of situational awareness and disorientation after release from the tow line, which led to the selection of an inappropriate landing site. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A glider pilot became disoriented while searching for lift after a tow release and inadvertently landed on a narrow ultralight strip, striking a tree with the tail.

What happened

The pilot of a glider reported that following a release from the tow line, he encountered difficulty locating thermal lift. In an effort to concentrate on finding rising air currents, he became disoriented relative to the runway location. When he decided to return to the airport, he inadvertently selected a narrow strip of ground designated for ultralight vehicles rather than the main runway. After touching down, the pilot swerved to avoid a tree, causing the glider's tail to strike the ground.

The investigation

The investigation focused on the pilot's account of the flight sequence and the physical evidence at the landing site. The primary finding was the discrepancy between the intended airport runway and the actual landing area selected by the pilot. The mechanical examination confirmed that the damage was consistent with a tail strike during an evasive maneuver to avoid a stationary object.

Findings

The incident highlights the risks associated with spatial disorientation in gliding operations, particularly when the pilot is heavily focused on performance metrics like lift detection rather than situational awareness. The selection of an inappropriate landing site indicates a loss of orientation regarding the airport's layout and available facilities. The subsequent collision with the tree was a direct result of the pilot's attempt to correct the trajectory after realizing the error in the landing site selection.

Safety message

Pilots should maintain continuous situational awareness, especially during the critical phase immediately following tow release. It is essential to balance the search for lift with navigation and orientation to the airport environment to prevent inadvertent landings in unsuitable areas.

Probable cause

The pilot's loss of situational awareness and disorientation after release from the tow line, which led to the selection of an inappropriate landing site.
