Accident Overview
On 13 August 1967 at approximately 1640 local time, a Piper J3C aircraft registered as HB-OSM experienced a nose-over during landing at La Côte airfield in the canton of Vaud, Switzerland. The aircraft was operated by the Vaud section of the Aéro-Club de Suisse (Aé.C.S.) and was on a private direct flight from La Blécherette. The pilot and a female passenger were uninjured, while the aircraft sustained serious damage.
Aircraft and Pilot
The Piper J-3-C (serial number 12252, built 1944) was a tandem two-seat, high-wing monoplane with fixed landing gear and a tailwheel, powered by a 90-horsepower Continental C-90-8F engine. Its empty weight was 372 kg, and at the time of the accident, the takeoff weight was approximately 584 kg, slightly above the maximum of 580 kg. The center of gravity remained within prescribed limits. The aircraft had accumulated about 555 total flight hours, with the last 100-hour inspection completed on 7 August 1967.
The pilot, born in 1920, held an expired private pilot license (valid until 20 August 1965) and a special permit for training flights (valid until 20 August 1967). His total flying experience was about 188 hours over 841 flights, including 101 hours on the Piper J3C. His last medical examination on 12 August 1967 found him fit. The passenger had no aeronautical background.
Flight and Landing Sequence
The pilot intended to leave Switzerland on 14 August and needed to accumulate a few more flight minutes to renew his private pilot license before his special permit expired. Despite the permit restricting flights to training only (with an instructor or solo under supervision), he carried a passenger.
After an uneventful flight, the pilot arrived over La Côte airfield and performed a half-turn to observe the landing direction, but did not check the windsock. In turbulent conditions, he entered the turn left and aligned with runway 22. His approach was high and fast, and he landed long.
On the first touchdown, after the first half of the runway, only the main wheels contacted the ground. The aircraft bounced and floated about one meter above the surface, maintaining a tail-high attitude. It touched down a second time with the main gear and then nosed over abruptly after a few meters.
Damage
The propeller, vertical fin, and canopy were broken; the engine cowling and left wing leading edge were dented; the right wing and its bracing wires were twisted. Damage was assessed at about 40%. There was no ground damage.
Investigation and Cause
Brake tests showed they were effective but progressive. No mechanical anomalies were found. The pilot stated: "I hesitated to go around and, thinking I was too long, I braked, which caused the complete overturning of the machine." A witness reported that on the second touchdown, the pilot seemed tense and likely had his feet on the brakes.
The investigation determined that the pilot had 220 meters of runway remaining plus 150 meters of usable terrain before a wheat field. The slight overweight had no influence. The nose-over was attributed to the pilot's abrupt application of the brakes following a landing that was too long.
