What happened
The pilot initiated a descent toward the airport, reaching the minimum descent altitude of 740 feet mean sea level. Visual contact was established approximately one-half mile east of the airfield. To align with the runway, the pilot executed a slip maneuver to reduce speed and gain height control, positioning the aircraft within 200 feet of the runway threshold.
Upon touchdown in the middle of the runway, both main landing gear wheels locked up immediately. The friction caused the aircraft to nosed over onto its nose. Following the incident, the pilot stated that they may have had their feet on the brakes at the moment of touchdown, which likely contributed to the wheel lockup.
The investigation
Investigation of the accident site and aircraft condition confirmed the nosed-over position. Examination of the landing gear indicated that both main wheels were locked upon impact with the runway surface. No mechanical failure of the braking system prior to touchdown was identified in the available records.
Findings
- N12345 (aircraft registration) sustained substantial damage to the nose and forward fuselage due to the nosed-over position.
- The pilot reported applying brake pressure during the initial phase of ground roll.
- Weather conditions three minutes after the accident were reported below approach minimums, indicating potential runway contamination or reduced visibility.
- Wheel lockup on touchdown was the primary mechanical factor leading to the loss of directional control and subsequent nosed over.
Safety message
Pilots should avoid applying brakes during the initial phase of landing roll unless absolutely necessary for speed control. Applying brakes at touchdown can cause wheel lockup, especially on wet or contaminated runways, leading to a loss of directional control and potential nosed-over accidents.
