Training

The crew was performing a local training flight at Decatur Airport, consisting of touch-and-go maneuvers. On final approach to runway 24, the instructor elected to simulate a failure of the right engine. Anticipating the touch-and-go procedure, the instructor deactivated the yaw damper system while the aircraft was about 10-20 feet above the runway. As the speed increased, the instructor called out 'speed' twice when the copilot reduced the power on the left engine. The aircraft rolled to the right, causing the right wingtip to struck the ground. The aircraft went out of control, veered off runway and came to rest, bursting into flames. Both pilots escaped with minor injuries while the aircraft was destroyed.

The crew of the missing airplane was conducting a local area familiarization flight under Title 14, CFR Part 91. At the time of the flight, visual meteorological conditions prevailed, with occasional moderate turbulence forecast for the area. The airplane was routinely contracted for animal and bird counts, and the flight was to include low level flight simulating such a mission. The three occupants of the airplane were the pilot, company check pilot, and another company pilot riding along as a passenger. Both the pilot and the check pilot held airline transport certificates, and were experienced in the make and model of the accident airplane. The airplane was equipped with a satellite position reporting device that updated position, groundspeed, and altitude every 2 minutes. Radar and GPS track information indicated the accident airplane was flying low and slow along a peninsula coast over a saltwater inlet, and turned toward the center of the inlet. The track stopped about 3 miles offshore. The data indicated that while flying along the inlet, the airplane descended to 112 feet above ground level (water), and climbed as high as 495 feet, which was the airplane's altitude at the last data point. The airplane's groundspeed varied between 97 and 111 knots. The area of the presumed crash site experiences extreme tides and strong currents, with reduced visibility due to a high glacial silt content. An extensive search was conducted, but the airplane and its occupants have not been located. An examination of the airplane's maintenance logs did not disclose any unresolved maintenance issues.

The crew was completing a local training flight at Semarang-Ahmad Yani Airport. On final approach, the twin engine aircraft crashed in unknown circumstances in a pond located 500 metres short of runway 13. Both pilots were killed.

The private pilot receiving instruction and his flight instructor departed on runway 06 with a headwind of 17 knots gusting to 23 knots. Witnesses said that the pilot had transmitted on Common Traffic Advisor Frequency the intention of practicing a loss of engine power after takeoff, and turning 180 degrees to return to the airport. Another witness said that the airplane pitched up 30 degrees while simultaneously banking hard to the right in an uncoordinated manner. He said that as the airplane rolled to the right, the nose of the airplane yawed down to nearly 45 degrees below the horizon. Subsequently, the airplane's wings rolled level, but the aircraft was still pitched nose down. He said the airplane appeared to be recovering from its dive. A witness said that the airplane appeared to be in a landing flare when he observed dirt and grass flying up behind the aircraft. He said the airplane's right wing tip and engine impacted terrain, and a fire ensued that consumed the airplane. Examination of the accident site revealed that the airplane's right wingtip hit a 10 inch in diameter rock and immediately impacted a wire fence 10 inches above the ground. Approximately 120 feet of triple wire fence continued with the airplane to the point of rest. No preimpact engine or airframe anomalies which might have affected the airplane's performance were identified. The weight and balance was computed for the accident airplane at the time of the accident and the center of gravity was determined to be approximately one inch forward of the forward limit.

The twin engine aircraft departed Santo Antonio Airport on a local training flight, carrying four pilots. While on approach to runway 29, the aircraft went out of control and crashed in the sea few km offshore. All four occupants were killed.

The aircraft was conducting stop-and-go landings on Runway 36 at the airport in La Ronge, Saskatchewan. On short final approach for the third landing, the aircraft developed a high sink rate, nearly striking the ground short of the runway. As the crew applied power to arrest the descent, the autofeather system feathered the left propeller and shut down the left engine. On touchdown, the aircraft bounced, the landing was rejected, and a go-around was attempted, but the aircraft did not attain the airspeed required to climb or maintain directional control. The aircraft subsequently entered a descending left-hand turn and crashed into a wooded area approximately one mile northwest of the airport. The first officer was killed and two other crew members sustained serious injuries. The aircraft sustained substantial damage. The accident occurred during daylight hours at 1245 central standard time.

The commercial certificated pilot was positioning the multi-engine, retractable landing gear airplane for a corporate passenger flight under Title 14, CFR Part 91, when the accident occurred. Upon landing at the destination, the pilot aborted the landing, and after climbing to about 100 feet agl descended, impacting in a canal. A witness who was not looking towards the runway, reported hearing the sound of a twin engine airplane approaching with the engines at reduced power, and then heard a scraping noise similar to the recent gear-up landing he had witnessed. Looking toward the runway, he said the airplane was midfield, left of the runway centerline, about 20 feet in the air with the landing gear retracted, and that he saw a cloud of dust, and heard what he thought was full engine power being applied. He said the airplane climbed to about 100 feet agl, and disappeared from view. Another witness with a portable VHF radio tuned to the unicom frequency, reported hearing the pilot say he was "doing an emergency go-around." The airplane descended striking utility poles, and impacted in a saltwater canal. An examination of the airport runway revealed a set of parallel propeller strike marks. The left and right sets of marks were 109 and 113 feet long, and the mark's center-to-center measurement is consistent with the engine centerline-to-centerline measurement for the accident airplane. No landing gear marks were observed. The airplane's six propeller blades had extensive torsional twisting and bending, as-well-as extensive chord wise scratching and abrasion. Several of the blades had fractured or missing tips. An examination of the cockpit showed the landing gear retraction/extension handle was in the up/retracted position, and the landing gear extension warning horn circuit breaker was in the pulled/tripped position. The landing gear emergency extension handle was in the stowed position. The nose landing gear was damaged during final impact, and was not functional. During the postimpact examination, both the left and right main landing gear were stowed in the up and locked/retracted position. The landing gear were released/unlocked and operated appropriately using the emergency extension handle. An examination of the left and right main landing gear showed no damage to the wheel doors, leg doors, wheels, or tires. All linkages and locking devices were undamaged, and appeared to function normally.

The right main landing gear collapsed on landing. According to the flight crew, after departure they preceded to Mountain Air Airport, where they performed a "touch-and-go" landing. Upon raising the landing gear following the touch-and-go landing, they got an "unsafe gear" light. The crew stated they cycled the gear back down and got a "three green" normal indication. They cycled the gear back up and again got the "gear unsafe" light. They diverted to Greensboro, North Carolina, and upon landing in Greensboro the airplane's right main landing gear collapsed. After the accident, gear parts from the accident airplane were discovered on the runway at Mountain Air Airport. Metallurgical examination of the landing gear components revealed fractures consistent with overstress separation and there was no evidence of fatigue. Examination of the runway at Mountain Air Airport by an FAA Inspector showed evidence the accident airplane had touched down short of the runway.

The crew departed Chattanooga-Lovell Field on a training flight to Pensacola-Forrest Sherman Field NAS, Florida. About 20 minutes into the flight, while cruising at low altitude, the aircraft contacted a tree and crashed a mile further on the slope of Mt Johns, near Villanow, Georgia. All four occupants were killed.

The airplane stalled on short final approach, and it impacted the ground. The purpose of the flight was for the student to receive dual flight instruction to become more acquainted with the airplane's handling characteristics. The student met with his certified flight instructor and received a briefing regarding the upcoming lesson involving, in part, takeoff and landing practice. The instructor directed his student to perform a simulated engine out approach, and engine power was reduced as the airplane glided toward the airport. The student entered a close in downwind approach and, at the direction of the instructor, then performed a left circling turn onto the base and final approach legs. The landing gear was lowered, and the student questioned the instructor regarding whether they could glide all the way to the runway. The instructor advised his student to maintain 90 knots airspeed. During the descent, as the airplane turned from the close in base leg onto the final approach leg, the instructor told his student "don't bank." The student rolled the wings level. Immediately thereafter, the left bank began a second time and the instructor again said, "Don't bank." The student replied, "I'm not." The instructor applied engine power and right rudder to reduce the left bank. The airplane stopped rolling left, and then rolled into a right bank, whereupon the right wing impacted the ground. At no time did the instructor direct his student to release the airplane's flight controls.
