CARNATION, WA, USA
N149BT
Ben Travis KITFOX IV
While in a cruise flight configuration the aircraft's engine started to lose power and eventually quit. The pilot executed a forced landing in a crowned hay field. Upon touchdown, the aircraft bounced, momentarily became airborne, then touched down a second time. In an effort to stop, the pilot intentionally ground-looped the aircraft. The aircraft came to rest in a irrigation canal that paralleled the hay field. The aircraft's main landing gear and both wings were substantially damaged. A post accident inspection of the engine revealed a large crack in the impulse line running from the engine's crankcase to the pulse fuel pump. A technical representative from Rotax Engines stated that a breech of this type in the impulse line would result in a failure of the pulse fuel pump.
On May 24, 1999, about 1705 Pacific daylight time, a Travis Kitfox, N149BT, registered to and operated by the pilot, was substantially damaged during an off-airport forced landing following a sudden loss of engine power. The accident occurred approximately one mile northeast of Carnation, Washington. The private pilot and his passenger were uninjured. No flight plan was filed and visual meteorological conditions prevailed for the 14CFR91 personal/pleasure flight. The flight originated from Sequim Valley airport, Sequim, Washington, approximately 1405 PDT.

Loss of engine power due to a cracked engine impulse line, which disabled the fuel pump. A factor was the intentional ground loop by the pilot.
