Training

The crew was completing a local training flight at Khartoum-Haj Yusuf Airport. Following several touch-and-goes completed successfully on runway 18, the crew landed the airplane and elected to takeoff when the captain encountered difficulties to raise the flaps from 40° to 16,5°. In such conditions, he decided to reject the takeoff procedure and initiated an emergency braking manoeuvre. The aircraft skidded on runway, overran and lost its right main gear before coming to rest against the ILS antenna for runway 36. Both pilots escaped uninjured while the aircraft was damaged beyond repair.

The crew was completing a local training flight at Jaipur-Sanganer Airport. After touchdown, the twin engine aircraft skidded on runway, veered off runway and came to rest. Both pilots escaped uninjured while the aircraft was damaged beyond repair.

Two Rockwell T-39N Sabreliner operated by the US Navy registered 165522 and 165525 departed Pensacola-Forrest Sherman Field for a training mission. In unknown circumstances, while cruising over the Gulf of Mexico, about 60 km offshore, both aircraft collided and crashed in the sea. All seven crew members on board both aircraft were killed. Debris were found about 64 km offshore, distant 10 km from each other.

The crew departed Twentynine Palms on a local training flight. Shortly after takeoff, the engine n°1 failed. The aircraft encountered difficulties to gain height when the engine n°4 lost power. The crew attempted an emergency landing in a sandy area located about 4,5 km past the runway end. All eight crew members escaped uninjured while the aircraft was damaged beyond repair.

Crashed in unknown circumstances in trees while completing a local training flight at Fort Bliss AFB. All four crew members were rescued, among them two were injured.

The mishap aircraft, call sign Pacer 43, was conducting pattern work operations during an off-station training mission at Ellsworth AFB, SD (RCA). Shortly before impact, the mishap crew was conducting a simulated single-engine approach to runway 31 at Ellsworth AFB. Subsequent analysis showed that there was a significantly greater amount of fuel in the left wing and left wing tip tank than the right. The gross fuel imbalance resulted from an unmonitored transfer of fuel from the right wing and right wing tip tank to the left that was initiated by the crew approximately nine and one-half minutes before impact. As the aircraft approached the point when it would normally transition to a flare, it leveled off and began a climbing turn to the west, toward the tower. It did not touch down prior to the turn, but veered left immediately during the flare, and then rolled back to wings level momentarily as it climbed. The heavier left wing, and application of power to the right engine for the go-around, caused the aircraft to roll back into a steeper left turn, stayed in a climbing left turn with the bank continuing to increase until il rolled through more than 90 degrees of bank. As the aircraft reached the highest point of the climb (approximately 450 feet), the bank angle was more than 90 degrees, and perhaps slightly inverted as the nose dropped and the aircraft began to descend. The aircraft impacted the ground in a grassy field.

The crew was completing a training flight from Zagreb to Slavonski Brod and back. After touchdown at Zagreb-Pleso Airport, the single engine airplane went out of control, nosed down and came to rest. All three occupants were rescued, among them one was slightly injured. The aircraft was damaged beyond repair.

The twin engine aircraft departed Moulins-Montbeugny Airport in the morning on a training flight to Clermont-Ferrand, carrying two passengers and two pilots. The goal of the flight was to extend the IFR rating of the pilot in the left seat. Following a stop in Clermont-Ferrand, the crew returned to Moulins. Over Moulins, the crew was cleared by ATC to leave the frequency and reported his intention to perform several manoeuvres in the area of Moulins Airport for a period of 30 minutes. Three touch-and-go were conducted on runway 26 then the crew continued at an altitude of about 2,000 feet when the aircraft became unstable on its roll axis. It nosed down and crashed in a wooded area called 'Bois de Bordes' located 7 km north of the airport, bursting into flames. The aircraft was totally destroyed and all four occupants were killed.

During a forced landing the left wing struck a light standard pole, and the airplane came to rest inverted after colliding with a fence. The purpose of the flight was to conduct recurrent training to include emergency procedures. On the accident flight the certified flight instructor (CFI) initiated a simulated engine failure after takeoff during the initial climb out. The student advised the tower, and turned crosswind at 700 feet agl. The student set up for landing, which included lowering the landing gear and adding 10 degrees of flaps. On short final, descending through 400 feet agl, both the CFI and student realized they would not make the runway. Both pilot's advanced the throttle, to arrest the descent and perform a go-around. There was no corresponding response from the engine. During the final stages of the emergency descent, the pilot maneuvered the airplane to avoid a work crew at the airport boundary fence and the airplane collided with the light standard pole and a fence. An airframe and engine examination discovered no discrepancies with any system. Following documentation of the engine and related systems it was removed and installed in an instrumented engine test cell for a functional test. The engine started without hesitation and was operated for 44 minutes at various factory new engine acceptance test points. During acceleration response tests, technicians rapidly advanced the throttle to the full open position, and the engine accelerated with no hesitation. A second acceleration response test produced the same results. According to Textron Lycoming, there were no discrepancies that would have precluded the engine from being capable of producing power.
