On June 5, 1993, at approximately 1445 central daylight time, a Bell-Transworld Helicopter Corporation 47G-2, N9238Z, was substantially damaged when it collided with trees during an uncontrolled descent, near Wynne, Arkansas. The aircraft, owned and operated by Jimair, and flown by a commercial pilot, was on a local aerial application flight. There was no flight plan filed and visual meteorological conditions prevailed throughout the area. The pilot, the sole occupant, was not injured. According to the pilot, he was about to finish seeding a field with rice when he pulled up from a swath run and the engine lost power. The pilot stated that as he pulled up, the engine "bogged down" and lost power, but did not quit totally. He further stated that the aircraft began to settle toward the ground and collided with trees. The aircraft subsequently impacted the ground. According to information received from the operator, post-accident inspection revealed that the engine had experienced a magneto failure.
PARTIAL POWER LOSS DUE TO THE FAILURE OF ONE MAGNETO. A FACTOR WAS THE LACK OF SUITABLE TERRAIN FOR THE FORCED LANDING.
