Training

The crew was completing a local training flight at Samarinda Airport. While on a fourth approach, the twin engine airplane stalled and crashed on a softball field located in the Segiri sports complex near the airport. Both pilots were injured and the aircraft was destroyed.

Crashed in unknown circumstances in the sea off Prachuap Khiri Khan while completing a local training flight. The pilot, sole on board, was killed.

The purpose of the flight was for the second pilot to perform an evaluation of the first pilot, who was recently designated by the operator as a backup pilot. Following several successful flights with and without passengers, the pilots discussed single engine operations, and the first pilot reduced the right engine's power to flight idle and feathered the propeller. During the final leg of the approach to landing, the airplane crossed over a fence near the runway threshold, and the first pilot pitched the airplane downward. The nose landing gear contacted the runway "hard," and the airplane began to bounce. After several bounces, the first pilot elected to abort the landing, increased power on the left engine to "full." As the first pilot pitched the airplane upward, it yawed to the right, "stalled," and impacted the ground.

The twin engine aircraft departed Pisco Airport on a local training flight with 13 people on board, among them one Guatemalan instructor and several pilots under training on this model recently purchased by the Peruvian Armed Forces. Seven minutes after takeoff, the instructor shut down the left engine to simulate a failure when control was lost. The aircraft crashed and burned. All 13 occupants were killed.

Prior to the accident flight, the air tanker airplane had flown 9 times on the day of the accident, for a total flight time of 5 hours and 46 minutes. The purpose of the flights was to provide recurrent training for pilots scheduled to conduct fire-fighting operations for the United States Department of Agriculture Forest Service (USFS) during the upcoming fire season. Pilots aboard the airplane during the earlier flights reported no mechanical problems with the airplane. As was the mission for other flights that day, the accident flight, the tenth flight, was a training flight to conduct practice drops of water over an area of rugged mountainous terrain located north of the airport. Aboard the flight were the captain, the copilot, and the company's Chief Pilot, who was providing flight instruction. The Chief Pilot had been on board all the flights that day. Radar data indicated that the flight departed the airport and proceeded about 10.5 nautical miles to the north where it began maneuvering in a manner consistent with the conduct of practice water drops. The data showed the airplane entering and then following a right-hand racetrack pattern oriented northeast-southwest, during which it appeared that practice drops were being made on the southwest leg. During the last minute of the flight, the airplane was on the northeast leg of the racetrack pattern, flying up a valley that was oriented northeast-southwest with uphill being to the northeast. The airplane's flight path was initially near the middle of the valley. During the last 36 seconds of the flight, the airplane's flight path began to deviate towards the rising terrain on the eastern side of the valley. The last two radar hits show the airplane at an altitude of less than 100 feet above ground level. The airplane had completed approximately 1.75 circuits of the racetrack when the data ended with the airplane at 2,900 feet msl, heading northeast. The initial impact point was located about 2,150 feet northwest of the last radar data point at an elevation of about 2,450 feet msl, indicating the airplane entered a left descending turn and completed about 90 degrees of turn between the last radar hit and the impact. No distress calls were received from the airplane. According to local authorities, witnesses observed a "fire ball" at the time of the accident. Examination of the wreckage site revealed that the airplane impacted on about a 304 degree magnetic heading in a 40 degree left bank with the left wingtip striking the ground first. The airplane was severely fragmented and a severe post crash fire burned most of the structure and surrounding vegetation. Remnants of the entire airplane were accounted for at the wreckage site. There was no evidence of pre-existing structural failures or impact with foreign objects in any of the wreckage. All four of the engines and propellers were found at the wreckage site. The engines did not have any indications of an uncontainment, case rupture, or pre-impact in-flight fire. All four engines had damage to the compressor and/or turbine rotors that was consistent with engine operation. The cockpit engine instrumentation gages indicate that all four engines were running at about 2,200 shaft horsepower at impact. Review of the airplane's maintenance records did not reveal any chronic issues with the airplane nor any system/component anomalies that would have contributed to the accident. The airplane was equipped with neither a cockpit voice recorder (CVR) nor a flight data recorder (FDR) and Federal Aviation Regulations did not require the airplane to be so equipped. The reason for the in-flight collision with terrain could not be determined.

Few minutes after takeoff from Niigata Airport, while flying in good weather conditions, the twin engine aircraft crashed on Mt Mikagura located about 55 km southeast of Niigata. All four crew members were killed. They were engaged in a local training mission.

Assigned to the 352nd Special Operations Group based at RAF Mildenhall, the four engine aircraft departed Tirana-Rinas Airport in the evening for a night training mission with the Albanian Army. While flying at low height, about 300 feet above the ground by night and using night-vision goggles, the crew elected to gain height while approaching a ridge. Unable to climb, the aircraft stalled and crashed in hilly and snow covered terrain. The aircraft was destroyed and all nine occupants were killed.

The pilot stated that the landing on runway 27 had initially been without incident. During the landing rollout, while the engines were in reverse and brakes were being applied, one of several deer which had entered the airport property, crossed the runway, and impacted the airplane's nose wheel. The impact threw the deer into the left propeller, and the propeller was detached and it punctured the fuselage.

The crew departed Harare Airport for a local night training flight. Shortly after takeoff, the twin engine aircraft lost height and crashed. Both pilots were killed.

The purpose of the flight was for the flight instructor to provide multiengine airplane training, in a late 1930's vintage amphibious airplane, to his brother, a single engine airplane rated private pilot. No published performance data was available for the airplane, and according to the flight instructor, much of what he knew about the performance of the airplane he learned from previous flights. Just after takeoff on the accident flight, and about 600 feet above ground level (agl), and as the pilot was retracting the landing gear and starting a left turn to the crosswind leg of the traffic pattern, the flight instructor retarded the right throttle in order to simulate a failure of the right engine. The pilot executed the procedures for an in-flight engine failure and the instructor looked out of the window to check for traffic in the airport traffic pattern. The flight instructor then heard the pilot state "I am at blue line but losing altitude." The flight instructor continued to scan for traffic and moved the right throttle forward to about the "half throttle" position. The pilot could not recall if he had adjusted either of the power controls after the initial application of power for takeoff. The airplane continued to descend, impacted the ground, and caught fire.
