## Probable cause

the pilot misjudged distance and altitude and failed to attain the proper landing touchdown point.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Overrun, landing
  - distance/altitude - misjudged, pilot in command (cause)
  - proper touchdown point - not attained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ground
  - ground loop/swerve - encountered, pilot in command

## Analysis

The glider landed long, went into the overrun area and ground looped.  The pilot was tow launched from runway 8.  Winds were light (5-15 knots) and variable.  Upon reentering the airport traffic pattern he followed landing traffic for runway 26.  On final approach for runway 26 he was at 350 feet and had 1,500 feet of runway remaining below him.  He landed long and touched down approximately 30 feet from the departure end of the runway pavement.  The glider continued to rollout into the grass overrun.  About 20 mph, the left wing touched the ground, and the glider ground looped to the left, damaging the left wing and fuselage.

## Factual narrative

On December 23, 2004, at 1145 Hawaiian standard time, a Schweizer SGS 1-26B, N2751Z, landed long and collided with terrain at Dillingham Field, Waialua, Hawaii.  Honolulu Soaring Club operated the glider, piloted by a private glider pilot, under the provisions of 14 CFR Part 91.  The pilot was not injured, and the glider was substantially damaged.  Visual meteorological conditions prevailed, and a flight plan had not been filed.  The flight originated at 1110 from Dillingham Field.

The pilot stated in the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2) that he was tow launched from runway 8.  Winds were light (5-15 knots) and variable.  Upon reentering the airport traffic pattern he followed landing traffic for runway 26.  He approached runway 26 at 350 feet and had 1,500 feet of runway below him.  He landed long, touched down approximately 30 feet from the departure end of the runway pavement, and continued to rollout into the grass overrun.  About 20 mph, the left wing touched the ground, and the glider ground looped to the left, damaging the left wing and fuselage.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
