## Probable cause

THE PILOT'S FAILURE TO COMPENSATE FOR WIND CONDITIONS DURING A CROSSWIND LANDING. THE CROSSWIND WAS A FACTOR.

## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - weather condition - crosswind (contributing factor)
  - directional control - not maintained, pilot in command
  - compensation for wind conditions - inadequate, pilot in command (cause)
- Overrun, landing - flare/touchdown
- On ground/water collision with object, landing - roll
  - object - wire,transmission
  - object - tree(s)

## Analysis

DURING A FULL STOP LANDING ATTEMPT, THE AIRPLANE BOUNCED TWICE AT TOUCHDOWN AND THE PILOT LOST CONTROL OF THE AIRPLANE WHEN HE ENCOUNTERED A CROSSWIND. THE AIRPLANE VEERED OFF THE RUNWAY AND COLLIDED WITH A UTILITY LINE AND A TREE. THE NEAREST WEATHER REPORTING FACILITY RECORDED THE WINDS AS 140 DEGREES AT 8 KNOTS. THE PILOT REPORTED THE WINDS AT THE ACCIDENT AIRPORT EASTERLY AT 10 KNOTS, GUSTING TO 15 KNOTS. THE PILOT DID NOT REPORT A MECHANICAL PROBLEM WITH THE AIRPLANE.

## Factual narrative

On April 9, 1994, at 1530 eastern daylight time, a Beech C-23, N6639C, collided with the ground during an attempted landing to runway 21 at Collegedale Municipal Airport, Collegedale, Tennessee. Visual weather conditions prevailed at the time of the accident, and  the personal flight operated under 14 CFR Part 91, with no flight plan filed. The airplane sustained substantial damage, and the pilot and passenger received minor injuries. According to the pilot, the flight departed Cincinnati, Ohio, at 1230 hours.

During a full stop landing attempt, the airplane bounced twice at touchdown and the pilot applied power to start a go around. The pilot confirmed that power was added in an attempt to salvage the landing. He further stated that a gust of wind, approximately fifteen knots, pushed the airplane off the runway, and he lost control of the airplane. The airplane collided with utility lines, a tree, and the ground. No mechanical problems with the airplane were reported by the pilot.

## 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.
