On August 13, 2016, about 1100 central standard time, a Cessna TU206B airdrop configured airplane, N29225, registered to the pilot and operated by Gypsy Moth Skydive LLC of Benton, Kansas, sustained substantial damage during a forced landing after a loss of engine power while maneuvering in the vicinity of Skiatook, Oklahoma. All seven occupants, the private pilot and six passengers (parachutists), sustained minor injuries.
The airplane experienced a total loss of engine power during a skydiving flight. After the pilot switched the fuel tank selector from the left fuel tank to the right fuel tank position, the engine restarted. The pilot continued the flight. While returning to the departure airport and preparing for landing, the pilot switched the fuel tank selector back to the left fuel tank position because the fuel gauge indicated a greater fuel quantity.
The pilot of a Piper L-4 airplane reported that shortly after he started the taxi roll from the parking area, he initiated a shallow turn toward the taxiway. As he reached the taxiway he steered to follow the centerline, however, the airplane continued to turn to the right. He reported, in part, that the left brake inputs were not responsive and the airplane continued to the right and collided with a standing occupied Cessna.
The pilot was returning to the airport after releasing some skydivers. He was following a training airplane in the traffic pattern and was gaining on it, so he decided to extend his downwind leg. On final approach to runway 08, his airplane was still gaining on the other airplane. The pilot reduced power and raised the nose to reduce airspeed to 85 mph.
According to the pilot, she dropped her load of skydivers and was coming in for a landing. She “could see fog rolling in fast” and knew she “had to get…on the ground.” She “landed at a higher speed which is normally fine but because of the runway conditions, which were slick, [she] had minimal braking and ran out of 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.
A commercial plt was flying a group of parachutists for a skydiving club. The aircraft encountered turbulence during a climb to 4,500 feet agl. As the second jumper was exiting, the aircraft dropped and the parachutist struck the horizontal stabilizer. The outer four inches were bent downward and the assembly was pulled one inch from the fuselage. The plt made a normal landing and an inspection revealed some bulkhead damage in the tail section. The parachutist was not injured. Read the NTSB...
Both acft were operating in vfr conditions modified by slight haze, high overcast and low sun angle near airport. N6161m was performing lazy eight maneuvers in a normal practice area two miles east of airport; n8267q was in clockwise orbital descent for landing following a parachute jump plane. Radar data and witness informtion show that on east side of airport, n8267q deviated from orbit and proceeded southeast as n6161m completed north end of figure eight in right turn away from airport and proceeded south. Acft converged at about 30 degree closing angle with n6161m climbing and n8267q descending and collided at about 2500 ft agl. Read the NTSB...
The acft lost part of one blade of the propeller during the climb to cruise phase of operation. The passengers were skydivers so they used their parachutes in an exit of the acft as the airframe started to vibrate. The plt made a successful landing on the arpt without power. All the jumpers landed safety. Visual examination of the propeller showed that the blade had separated 10 to 12 inches outboard from the blade root. The fracture exhibited evidence typical of high cycle fatigue and overload stress. Read the NTSB...
