A US Army Pilatus UV-20A collided in midair with a Cessna 182C during parachute jumping operations. The collision occurred about 4,800 feet mean sea level (msl) (2,800 feet above ground level (agl)) on the northeast side of runway 12 abeam the approach end. Both aircraft had made multiple flights taking jumpers aloft prior to the accident. The Pilatus departed runway 12 about 5 minutes prior to the Cessna’s departure on the same runway.

After the pilot dispatched two parachutists, the pilot commenced his descent to return to the airport. While on final approach, approximately 200 feet AGL, the engine lost power. The pilot attempted to land in a nearby open field rather than to attempt maneuvering around high power lines near the airport.
The certificated commercial pilot was conducting skydiving operations in the vicinity of the accident airport. After the airplane climbed to about 11,500 feet msl, all three of the skydivers aboard exited the airplane, and the pilot began a descent to return to the departure airport. The pilot said that while on approach, all engine power was lost, and emergency engine procedures did not restore engine power.
After the sky divers exited the airplane at 12,000 feet, the engine lost power while the airplane was descending through 10,000 feet. The pilot switched fuel tanks and engine power was reestablished. The engine again lost power at 4,000 feet and the pilot attempted a forced landing at his home base airport.
The pilot stated that as the aircraft descended, the engine was operating at 2000 rpm, and the selected manifold pressure was 15 in Hg, and at 8,000 feet he noticed that the engine had ceased operating. Prior to noticing that the engine had ceased operating he said everything had been normal, but as he maneuvered to land he felt he was too far down the runway to land safely, so he elected to perform a go-around.
The airplane nosed over in a cornfield during a forced landing after a total loss of engine power. The pilot reported he released the parachutists at 10,100 feet msl over the drop zone and started the descent to the south due to better cloud clearances and to keep clear of company traffic. He reported that he applied carburetor heat before descending.
After landing at night and stopping on the ramp, a passenger was seriously injured after walking into the propeller blade after exiting the aircraft.
A de Havilland DHC-6 and a Beech King Air 90 were to make a formation air drop of skydivers from 14,000 feet msl. The de Havilland was to be the lead aircraft with the King Air in trail. As the skydivers prepared to exit, the King Air was traveling faster than the de Havilland, and the pilot of the King Air had to pitch up and bank right to avoid the de Havilland.
The pilot and 21 jumpers were aboard the airplane for the local skydiving flight. The airplane took off to the north on the wet grass runway. Jumpers reported that during the initial takeoff climb, the aircraft assumed a “very steep angle of attack,” and described the pilot “winding the wheel on the lower right side of the chair clockwise, frantically,” and “busy with a wheel between the seats.”
The pilot of the skydiver dropping aircraft reported that the engine lost power at the end of his descent from the 12,000-foot drop altitude as the airplane approached a landing 3-mile base leg. When the engine lost power, he checked that the fuel selector was in the “both” tanks position, the mixture was in the “rich” position, and checked individual magnetos; all with no effect.
The airplane sustained substantial damage on impact with trees and terrain during a forced landing to a field following an in-flight loss of engine power. Skydivers had been dropped prior to the loss of engine power and the pilot reported no injuries. The pilot stated, “I climbed to 11000 [feet.] Was not getting usual climb rate. Before decent found I could not close cowl flaps. Decended to 6000 feet. Noticed eratic raise on manifold gage.
The pilot and eight parachutists were returning from a skydive meet. The pilot had obtained a weather briefing, which advised of instrument meteorological conditions at the destination, and filed a VFR flight plan, but it was never activated. Witnesses heard, but could not see, a twin engine turboprop pass over the airport, heading north out over the Great Salt Lake. They described the weather conditions as being a low ceiling with 1/4-mile visibility,
The flight departed with approximately 20 gallons of fuel in each fuel tank and offloaded skydivers at 10,500 feet, then descended to return with the throttle at idle, the fuel/air ratio leaned; and carburetor heat applied. At 2,000 feet, the pilot began to level off and, “realized I was having engine trouble and began my emergency procedures for an engine failure at altitude….”
After discharging three parachutists into a drop zone from about 12,000 feet mean sea level, the pilot attempted to return to the departure airport. The engine began surging as the airplane descended through 8,000 feet. The pilot continued the descent and entered the departure airport’s traffic pattern. He misjudged his distance from the runway, and when all engine power was lost turning onto the final approach leg he was unable to glide to the runway.
The flight had proceeded without incident until a visual approach was made to the destination airport, but a landing was not completed because of poor visibility due to ground fog. The pilot then requested vectors to another airport, and was advised by ATC that he was below radar coverage, and he could not be radar identified. The pilot stated he would proceed to a third airport;
The pilot reported that she taxied the aircraft to the grass covered run-up area in preparation for takeoff. As the aircraft moved over the grass, a ‘snapping’ sound was heard and the aircraft ’tilted back and to the right.’ The right wing and right side stabilizer contacted the ground.
After takeoff the pilot raised the landing gear and then had to take evasive action to the right to avoid a flock of birds. As he performed the evasive maneuver, he raised the flaps. The aircraft was slow, and he kept the nose down to build up speed for the climb. Just as he was to commence the climb, he caught a glimpse of a wire ahead. He pulled up rapidly, but contacted the wire with the right wing.
Prior to the day of the accident, the pilot had not flown out of the airstrip. During takeoff, the airplane traveled over a ‘soft spot’, and began to veer to the left. The pilot was unable to correct the turn, the airplane went off the left side of the runway and struck a tree. The runway was 1,515 feet long, 110 feet wide, and consisted of soft turf. Review of the pilot’s weight and balance calculations revealed that the airplane was approximately 300 pounds over the maximum gross takeoff weight.
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.
