## Probable cause

The pilot's premature extension of the speed brakes on landing resulting in the glider colliding with trees short of the runway.

## Sequence of events

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

- In flight collision with object, landing
  - object - tree(s)
  - speed brakes - improper use of, pilot in command (cause)
  - descent - premature, pilot in command

## Analysis

The pilot was on approach for landing and prematurely deployed the speed brakes resulting in the glider descending short of the runway and colliding with trees.

## Factual narrative

On December 9, 2000, at about 1555 eastern standard time, a Grob G102, registered to Seminole Flying & Soaring Inc., operating as a 14 CFR Part 91 personal crashed short of Seminole Lake Gliderport (6FLO), Clermont, Florida. Visual meteorological conditions prevailed and no flight plan was filed. The glider sustained substantial damage. The private pilot reported no injuries. The flight originated from 6FLO about 1 hour before the accident.

The pilot stated he was on approach for landing at 6FLO. He deployed the airbrakes too early and the glider collided with trees short of the runway.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
