A private pilot reported that his glider sustained structural damage during a hard landing in strong and gusty crosswind conditions at the departure airport. The pilot noted difficulty controlling the glider due to less than optimal use of dive brakes.

Accident Overview

A private pilot experienced a hard landing in a glider, resulting in structural damage to the forward fuselage and empennage. The pilot had departed from the same airport approximately 1.5 hours prior on a personal flight under Title 14, CFR Part 91. At the time of departure, a SIGMET was active for forecast and reported severe turbulence, and strong surface winds were reported at adjacent airports.

Landing Conditions

Upon return, the pilot reported that surface winds and turbulence had increased significantly. He estimated a 50-degree crosswind at 15 knots, with gusts to 29 knots. During the landing attempt, the glider encountered continued turbulence, and the pilot stated that the glider landed hard on the nose.

Pilot's Remarks

In his written report to the NTSB, the pilot noted that the difficulty in controlling the glider during landing was most likely exacerbated by his less than optimal use of the dive brakes. He also remarked that flights into such conditions should only be attempted by very experienced pilots.

Damage

The hard landing caused structural damage to the forward fuselage and empennage of the glider. No other injuries or damage were reported.

Probable cause

Difficulty controlling the glider during landing due to less than optimal use of dive brakes, as noted by the pilot.
