What happened
On May 22, 2001, a Piper PA28A 181 Archer III, registration OY-PAASX, arrived at Weston Aerodrome following a flight from Denmark via the United Kingdom. Upon arrival, the pilot initially prepared for an approach to Runway 07 based on local wind indicators. However, after communicating with the airfield clubhouse, the pilot was advised to use Runway 25 instead.
Due to a nearby housing estate and local turbulence, the pilot conducted a high approach to Runway 25. In an attempt to correct the excess altitude, the pilot pushed the nose down, which likely increased the aircraft's speed. The pilot subsequently performed the flare without applying additional power. This maneuver, combined with a tailwind of approximately 5 to 10 knots, caused the aircraft to float significantly down the runway. The aircraft touched down only 200 metres from the end of the pavement. Despite heavy braking, the aircraft could not stop within the remaining distance, overran the runway, and struck a boundary hedge and wire fence. The impact caused substantial damage to the wing leading edges, propeller, and engine cowling, though both occupants escaped without injury.
The investigation
The investigation examined the flight path, meteorological conditions, and airfield procedures. Investigators confirmed that the aircraft was airworthy and that no mechanical failures contributed to the event. The analysis focused on the pilot's approach profile and the accuracy of the wind information provided by the airfield. It was noted that the clubhouse, which provides advisory information, is situated in a sheltered area, making it difficult to accurately estimate wind speed from windsock movement alone. Furthermore, the investigation looked into the airfield's preference for Runway 25, which is often used to minimize noise for local residents.
Findings
- The final approach was performed at an excessive height and speed.
- The combination of a steep approach, high airspeed, and a tailwind led to a late touchdown with insufficient runway remaining for braking.
- The pilot failed to initiate a go-around despite recognizing the high approach and the presence of a tailwind.
- The advice provided by the airfield regarding the active runway may have been based on an inaccurate assessment of the wind.
- The use of a down-wind runway contributed to the excursion.
Safety action
- Weston Aerodrome was advised to consider installing an anemometer to allow for more precise measurement of wind speed and direction.
