The pilot stated that he was at 12,500 feet, preparing for a four-mile parachute jump run, when he had initial indications of a power/fuel problem. He said he told the skydivers to exit, then initiated a descending spiral to land, during which time the fuel flow became erratic. He said both engines ceased operating at 3,000 feet, and he did not account for the northwest wind, and crashed short of the runway.
The pilot stated that while descending through 6,000 feet msl, the engine lost power. The pilot reported that when he enriched the mixture, the engine regained power. He stated that he left the mixture full rich; however, when the airplane was at 600 feet and turning to base, the engine lost power again.
During its takeoff roll from a sod runway, the airplane’s pilot said a deer was running toward the airplane from its right side. The pilot said she ‘…throttled back and hit the brakes…[and the airplane] ground looped.’ Ground scars on the runway confirmed that the airplane made a left-hand, 180 degree turn that resulted in a collapsed right main landing gear and the outboard half of the right wing was bent upward about 20 degrees.
Witnesses reported that the single-engine airplane’s takeoff and climb appeared to be normal. As the airplane climbed through 400 feet, a puff of black smoke was observed emanating from the right side of the engine compartment. The airplane nosed up slightly, then nosed down turning about 360 degrees before descending rapidly from view.
While landing, the nose landing gear collapsed, and the airplane went off the left side of the runway. Four bolts secured the nose landing gear. Two of them were missing, and rust was evident in the slots where the bolts were originally secured. The pilot was able to recover one of the bolts. Examination of the bolt revealed that shearing was evident, consistent with a secondary failure.
The pilot reported that after takeoff he saw an approaching thunderstorm and returned to the airport to land on runway 21. The pilot stated that when he arrived at the airport there was a 90-degree crosswind. He estimated that the wind was 120 degrees at 25 knots, with 5-10 knot gusts. The pilot further reported that as the airplane touched down, ‘a gust of wind kept the wheels from settling so I could not brake effectively,’ and the aircraft ran off the end of the 3,000-foot-long runway and impacted a fence and a ditch.
The aircraft was landing on runway 36 when the right main landing gear separated. The aircraft departed the right side of the runway and came to rest. The pilot and passenger were not injured. Inspection revealed a fracture of the right spring landing gear leg about one inch outobard of the fuselage skin.
The airplane impacted the terrain approximately 2,065 feet south of the departure end of runway 22. Damage to the cockpit section of the wreckage indicated a nose down crush angle of approximately 80 degrees. The wreckage path was on a 208 degree heading, and the distance from the initial impact to the location of the empennage was about 142 feet. The cockpit and cabin were destroyed by post impact fire.
The pilot said he was landing on runway 25 and encountered a dust devil on touchdown. The airplane veered off the runway and into the dirt area beside the pavement, collapsing the right main landing gear.
The aircraft was being flown to the Aero Park Airport in Menominee Falls, Wisconsin, after having been used for parachute activity at the East Troy Municipal airport. The aircraft collided with power lines 110 feet above the ground and subsequently impacted the ground 0.25 statute miles east-northeast of the approach end of runway 23.
The airplane quickly became airborne and started an extremely steep climb for several hundred feet, which was followed by an equally steep descent until the airplane collided with terrain. The airplane had just completed one jump flight, and a different pilot fueled the airplane in preparation for the accident flight. The airplane was configured with one seat on the left side for the pilot and a 2-inch pad with seat belts for up to four skydivers.
While climbing through 600 feet after takeoff, a loud bang was heard and a hole appeared in the top of the engine cowling. Oil leaked from the engine and covered the windshield. The engine did not stop running, but did loose power. A forced landing was landing was made in a field and the nose landing gear collapsed during rollout.
Following the 12th sport parachute jump of the day, which occurred after sunset, ground witnesses observed the airplane descend into the ocean in a left wing low, nose down attitude. They did not hear the engines sputtering or popping, or see the airplane make any erratic movements during its descent.
The airplane departed on a parachuting flight with 5 parachutists on board. Several witnesses reported hearing the airplane during climb out. Each witness described smooth engine noise, brief ‘sputtering,’ and then a total loss of engine power. The airplane descended straight ahead at the same pitch attitude, then the nose dropped, a parachutist exited, and the airplane entered a spiraling descent.
The pilot stated that after four parachutists had boarded the airplane, he began to taxi away from the gate. The pilot stated that the airplane traveled about 25 yards on the upward sloping grass terrain when the right main landing gear collapsed. Examination of the landing gear revealed a break approximately 10 inches from the inboard end of the landing gear leg at a point where it is clamped to the fuselage structure.
