He advanced the throttles "a little further," but when he did so, the left main landing gear dropped off the left side of the runway into soft mud. Subsequently, the airplane veered off the runway to the left, the nose gear collapsed, and the airplane stopped in the mud. The fuselage and engine firewalls sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that during the takeoff roll on a narrow runway about 70 to 80 knots, he noticed that the engines were not at full power. The pilot further reported that he advanced the throttles "a little further," but when he did so, the left main landing gear dropped off the left side of the runway into soft mud. Subsequently, the airplane veered off the runway to the left, the nose gear collapsed, and the airplane stopped in the mud. The fuselage and engine firewalls sustained substantial damage. The pilot did not report any preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: N795DE (not matched to a registry record) - Reported make and model: BEECH B200 (UNDESIGNAT) - Category: Airplane - Serial number: BB-1510 - Engines: P&W PT6A turbo prop; P&W PT6A turbo prop - Damage: Substantial damage - Flight: Positioning, Part 91 - Operator: Optimal Aviation Services - Registered owner: Devine Organics LLC. - Airworthiness certificate: Standard, Normal - Departed: 5CA7, Five Points, CA - Destination: VIS, VISALIA, CA - Airport: 5CA7, Agro-West, runway 16, 3,000 × 40 ft, asphalt - Equipment: Stall warning system, Auto-pilot, Electronic primary flight display ## Flight crew As NTSB recorded them.

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.
