A glider pilot inadvertently retracted the landing gear instead of deploying spoilers, leading to a high-speed touchdown and intentional ground loop to avoid a berm. The glider was destroyed and the pilot sustained minor injuries.

Incident Overview

A glider pilot executed a high parasite drag maneuver during landing. On approach, the pilot realized the glider would overshoot the first half of the runway and elected to land on the second half. While reaching for the spoiler handle, the pilot mistakenly pulled the gear handle, inadvertently retracting the landing gear.

Touchdown and Evasive Action

The glider touched down on the runway at approximately 70 knots. Fearing a head-on collision with a berm at the end of the runway, the pilot intentionally ground looped the glider. The aircraft struck the berm at a 90-degree angle to the left.

Damage and Injuries

The glider was destroyed in the event. The pilot received minor injuries.
