## Probable cause

the pilot's failure to maintain clearance.

## Sequence of events

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

- On ground/water collision with object, landing - aborted
  - object - runway light
  - clearance - not maintained, pilot in command (cause)

## Analysis

The accident occurred during the annual Experimental Aircraft Association's convention.  The pilot stated that he was cleared to land at the approach end of the runway behind another landing airplane.  After landing, he realized that he was over taking the other airplane and attempted to abort the landing.  During the abort he veered to the left to avoid a collision with the other airplane and impacted runway lights off the left side of the runway.

## Factual narrative

On July 25, 1995, at 1430 central daylight time, a Grumman AA-1B, N8976L, piloted by a private pilot, impacted a runway light on the left side of runway 27 (6,180' x 150' dry asphalt) during an attempted aborted landing at Oshkosh, Wisconsin.  The airplane sustained substantial damage.  The pilot reported no injuries.  The personal 14 CFR Part 91 flight was operating in visual meteorological conditions.  No flight plan was on file.  The flight departed Watertown, Wisconsin at 1245.

This accident took place during the annual Experimental Aircraft Association's convention.

The pilot stated that he was cleared to land at the approach end of runway 27, while traffic in front of him was instructed to land abeam the VOR site.  He said that during his rollout his airplane was over taking the airplane in front of him and to avoid a collision he attempted to abort his landing.  In the process, he veered to the left to avoid a collision and the wing impacted runway lighting to the left of the runway.  During the collision the airplane sustained substantial damage.
