On July 14, 2015 about 1456 central standard time, a Cessna 1959 year model 182B skydive equipped airplane, N2764G, registered to Cook Aviation of St. Louis, Missouri, was substantially damaged when it impacted terrain after the pilot bailed out (via donned parachute) due to flight control problems.
On May 9, 2014, about 1400 eastern daylight time, a Pacific Aerospace Corp 750XL, N750SS, experienced a left main landing gear separation following a hard landing and subsequent go-around at Warrenton Air Park
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 stated that he departed the airport with six parachutists for a jump flight. As the airplane approached 1,000 feet above ground level, he noticed that the airplane wasn’t climbing. He checked the engine gauges and noticed that the engine analyzer was flashing “CHT” and the cylinder head temperature was 454 degrees F. As the pilot pitched the nose down and turned back to the airport, he heard a muffled “thud” sound and saw white smoke pour from the engine.
The pilot said that he normally flew the airplane with the fuel selector positioned to the right main fuel tank during skydiving operations. However, on the day of the accident, maintenance was performed on the airplane, and three engine run-ups were performed using the left main fuel tank.
According to the pilot, as he taxied the airplane to the runway for takeoff, the left main landing gear collapsed. Examination revealed that the left main landing gear had fractured and completely separated from the airplane about 6 inches outboard of its attachment point at the airframe.
The pilot received an unsafe landing gear indication for the left main landing gear when he configured the airplane for landing. He cycled the gear and then attempted a manual extension, both without success. The pilot then completed the landing on the nose and right main landing gear. A post accident examination of the left main landing gear actuator revealed that the supports for the actuator bearings lacked lubrication and that the bearings displayed wear due to inadequate lubrication.
The flight departed to the east with four skydivers for a local jump. One witness stated that, immediately following the takeoff, about 200 feet above ground level, a “percussive” pop from the engine was heard. Two witnesses stated that the right wing dropped, and the airplane impacted the ground.
During flight at 10,000 feet above ground level, the engine began to vibrate and run rough. Shortly thereafter, a loud bang occurred and oil was present on the windscreen. The pilot attempted a forced landing, and during the forced landing, the airplane landed short of the runway and impacted a ditch.
The Beech King Air had undergone maintenance that included a landing gear disassembly and inspection in preparation for the airplane’s sale. Following the landing gear inspection, the left main landing gear strut was overfilled to an extension that exceeded maintenance specifications due to the strut not being able to maintain the manufacturer’s specified pressure/extension.
The pilot was departing from a soft, dry, 2,200-foot turf airfield using soft/short field procedures. After becoming airborne, the airplane settled back onto the runway, became airborne, and settled onto the runway a second time. At this time the right main wheel separated and the landing gear strut dug into the terrain spinning the airplane around and bringing it to an abrupt stop.
The airplane used for the skydiving operation was equipped with a foot step just above the right wheel, which the skydivers used to launch from the airplane. As the last of four skydivers stepped on the foot step, the right main landing gear fell away. The pilot reported that after he flew around for about 1 1/2 hours to burn off fuel, he intended to perform a low pass over the runway before coming around to land.
The private pilot stated that he was at an altitude of 3,500 feet when the engine stopped producing power. He made a forced landing to field and struck a cedar post with the airplane’s nose wheel and subsequently flipped over resulting in structural damage to the vertical stabilizer
The pilot reported that there were no observed anomalies with the left wing prior to the flight. During the flight, which was conducted as a local parachute operation, the pilot performed a descending turn. The left wing’s aileron bound when the pilot attempted to level the bank. The pilot declared an emergency.
The pilot reported that the airplane, which was used for sky diving operations, was climbing through 7,000 feet mean sea level (msl) when he heard an explosion followed by a metal grinding noise coming from the engine section of the airplane. He felt the airplane vibrate, and smoke began to fill the cabin. He reported that the engine was not producing any power so he shut the fuel off and performed procedures to rid the cabin of smoke.
On July 29, 2006, about 1345 central daylight time, a de Havilland DHC 6 100, N203E, registered to Adventure Aviation, LLC, and operated by Skydive Quantum Leap as a local parachute operations flight, crashed into trees and terrain after takeoff from Sullivan Regional Airport, near Sullivan, Missouri. The pilot and five parachutists were killed, and two parachutists were seriously injured.
The airplane took off with its third lift of skydivers for the day. The engine began to run roughly at rotation, and due to the speed of the airplane, and the lack of remaining runway, the pilot elected to continue the takeoff. The pilot initially turned toward a public roadway for a forced landing, but the airplane continued to climb under partial power, so he maneuvered back to the airport for a downwind landing on the runway.
During takeoff roll, the airplane’s right landing gear tire blew. The left wing raised up and the airplane drifted right. The pilot shut down the power. The pilot then stated that the right wheel caught the raised grass area on the edge of the runway. The airplane’s tail swung to the right and the right landing gear collapsed.
The airplane lost engine power during descent. The 1,127-hour pilot elected to perform emergency engine out procedures and prepared for an emergency landing. After impact, the pilot observed the right engine nacelle engulfed in flames, which then spread to the fuselage. Review of the engine logbook revealed the engine was being operated in excess of 1,000 hours of the manufacturer’s recommended time between overhauls of 3,600 hours.
Witnesses observed the airplane depart to the north, and experience a partial loss of power during the takeoff climb. The airplane then began a turn to the left, and initiated what appeared to be a right base entry for a landing on runway 20. The airplane continued the turn, past 270 degrees, and as it flew beyond the end of the runway, the engine appeared to regain power and the airplane began a climb.
A witness reported that the airplane touched down within 1,000 feet of the runway threshold. The airplane rolled about 200 feet, and the nose gear collapsed. The airplane then veered left and came to rest inverted. The witness added that the nose gear collapse left scrape marks on the runway. Examination of the airplane revealed that the upper link of the nose gear torque knee had failed.
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 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.
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.
