Runway Overrun During Takeoff of a PA-28R-201 at Beromünster (HB-PQY)

Incident Overview and Aircraft Details On 7 August 2014, a Piper PA-28R-201 with registration HB-PQY, operated by Motorfluggruppe Langenthal, experienced a runway overrun during a private VFR takeoff at Flugplatz Beromünster. The aircraft was piloted by a German national born in 1957, who held a private pilot licence (PPL(A)) with 377 total flight hours, including 367 hours on the accident type. ## Sequence of Events The aircraft took off from runway 34 in a short-field configuration with full power and three occupants. It briefly lifted off at 55–60 knots at approximately three-quarters to four-fifths of the runway length but then returned to the runway. The pilot decided to abort the takeoff due to the short remaining runway distance, set the throttle to idle, and applied full braking. The aircraft rolled past the runway end, turned slightly to the right, and came to rest in a grassy area adjacent to the runway. The landing gear collapsed just before the aircraft stopped. ## Investigation Findings The Swiss Accident Investigation Authority (SUST) conducted a summary report based on available statements, as no formal investigation was performed. Data from the Avidyne primary flight display, multi-function display, and Flarm collision warning device, along with wreckage examination, indicated that the engine was producing full power during the takeoff roll and that no technical cause was identified. The aircraft's maximum takeoff mass was 2,750 lb, with a center of gravity range of 82 to 91.5 inches from the reference point. At the time of the takeoff roll, the aircraft weighed 2,808 lb, and the center of gravity was at 91.3 inches. ## Damage and Injuries The aircraft sustained damage to the landing gear and propeller. There was no third-party damage. The pilot and two passengers were lightly or not injured, with no serious injuries reported.
