Circumstances:
The flight crew, an airline transport certificated captain, and a commercial certificated co-pilot, were flying a restricted category, icing research equipped airplane in instrument meteorological icing conditions under Title 14, CFR Part 91. The purpose of the flight was to locate icing conditions for a prototype helicopter's in-flight icing tests. While in cruise flight, the airplane encountered icing conditions, and had accumulated about 1" of ice on the leading edges of the wings. The captain reported that he activated the wing deicing pneumatic boots, and the ice was shed from both wings. About 4 minutes after activating the deice boots, both engines simultaneously lost all power. The crew attempted several engine restarts, but were unsuccessful, and made a forced landing on frozen, snow-covered terrain. During the landing, the airplane struck several small, burned trees, and sustained substantial damage. The airplane's ice control system is comprised of two separate systems, one an anti-ice, the other, a deice. The majority of the wings' surfaces are deiced by pneumatic, inflating boots. The inboard section of the wings, directly in front of the engine air inlets, and the engine air inlets themselves, utilize a heated, anti-ice surface to preclude any ice accretion and potential for ice ingestion into the engines. The anti-ice system is not automatic, and must be activated by the flight crew prior to entering icing conditions. A researcher in the aft cabin photographed the airplane's wings before and after the activation of the deice boots. The photographs taken prior to the deice boot activation depicted about 1" of ice on the wings, as well as on the anti-ice (heated) inboard portion of the wings. The photographs taken after the deice boot activation revealed that the ice had been removed from the booted portion of the wings, but ice remained on the inboard, anti-ice segment. An engineer from the airplane's manufacturer said that if the anti-ice system was activated after ice had accumulated on the wings, it would take 2-4 minutes for the anti-ice portion of the wings and engine inlets to heat sufficiently to shed the ice. A postaccident inspection of the anti-ice components found no anomalies, and there was no record of any recent problems with the anti-ice system. The flight crew reported that the anti-ice activation switch is on the captain's side, and they could not recall if or when the anti-ice system was activated. They stated that they did not discuss its use, or use a checklist that addressed the use of the anti-ice system. A section of the airplane's flight manual states: "Failure to switch on the [anti-ice] system before ice accumulation has begun may result in engine damage due to ice ingestion." An inspection by an NTSB power plant engineer disclosed catastrophic engine damage consistent with ice ingestion.
Probable cause:
The pilot's improper use of anti-icing equipment during cruise flight, which resulted in ice ingestion into both engines (foreign object damage), the complete loss of engine power in both engines, and an emergency descent and landing on tree covered terrain. Factors associated with the accident were the icing conditions, inadequate crew resource management, and failure to use a checklist.

Circumstances:
During the takeoff climb, the airplane turned sharply right, went into a steep bank and collided with terrain. The airplane began a right turn immediately after departure and appeared to be going slow. A witness was able to distinguish the individual propeller blades on the right engine, while the left engine propeller blades were indistinguishable. The airplane stopped turning and flew for an estimated 1/4-mile at an altitude of 100 feet. The airplane then continued the right turn at a steep bank angle before disappearing from sight. Then the witness observed a plume of smoke. White and gray matter, along with two ferrous slivers, contaminated the chip detector on the right engine. The airplane had a rudder assist system installed. The rudder assist provided additional directional control in the event of a loss of power on either engine. The NATOPS manual specified that the rudder assist switch should be in the ON position for takeoff, landing, and in the event of single-engine operation. The rudder boost switch was in the off position, and the rudder boost actuator in the empennage was in the retracted (off) position. The owner had experienced a problem with the flight controls the previous year and did not fly with the rudder assist ON. The accident flight had the lowest acceleration rate, and attained the lowest maximum speed, compared to GPS data from the seven previous flights. It was traveling nearly 20 knots slower, about 100 knots, than the bulk of the other flights when it attempted to lift off. The airplane was between the 2,000- and 3,000-foot runway markers (less than halfway down the runway) when it lifted off and began the right turn. Due to the extensive disintegration of the airplane in the impact sequence, the seating positions for the three occupants could not be determined. One of the occupants was the aircraft owner, who held a private certificate with a single-engine land rating, was known to have previously flown the airplane on contract flights from both the left and right seats. A second pilot was the normal copilot for all previous contract flights; his certificates had been revoked by the FAA. The third occupant held an airline transport pilot certificate and had never flown in the airplane before. Prior to the accident flight, the owner had told an associate that the third occupant was going to fly the airplane on the accident flight.
Probable cause:
The flying pilot's failure to maintain directional control following a loss of engine power. Also causal was the failure of the flight crew to follow the published checklist and use the rudder assist system, and the decision not to abort the takeoff.

Circumstances:
Two Tupolev TU-16K of the Soviet Air Force departed Zavitinsk Air Base on a weather reconnaissance mission. Registered CCCP-07034 and CCCP-07514, both military airplanes were carrying a crew of six. While cruising at an altitude of 5,220 meters in good weather conditions, the TU-16 registered CCCP-07514 collided with an Aeroflot Antonov AN-24. Registered CCCP-46653, the AN-24 was completing flight SU811 from Yuzhno-Sakhalinsk to Blagoveshchensk with an intermediate stop in Komsomolsk-on-Amur, carrying 27 passengers and five crew members. It departed Komsomolsk-on-Amur Airport at 1456LT for the second leg of the trip and was cleared to climb to 5'200 meters. Both aircraft entered an uncontrolled descent and crashed in an uninhabited area located about 70 km east of Zavitinsk. Both aircraft were totally destroyed. All six crew members of the TU-16 were killed as well as 31 occupants on board the AN-24. Three days after the accident, a man aged 20 who was seating in the AN-24 was found slightly injured in the taiga.
Probable cause:
It was determined that the collision was the consequence of a poor organization and management of flights in the area of the Zavitinsk and the non-compliance of the published procedures. The collision was made possible by a lack of interaction, coordination and communication between the civilian and military air controllers.

Circumstances:
The four engine airplane departed Hao Island Airport runway 12 at 0500LT for a weather reports mission of seven hours and 40 minutes. During initial climb, both right engines n°3 & 4 lost power simultaneously. The pilot-in-command was able to complete a low pass over the airport before the airplane went out of control and crashed into the sea few hundred meters offshore. The aircraft was destroyed and all six occupants were killed.

Cpt Parage, navigator,
Adj Hecq, refueling operator.
Passengers:
- Adj Langlais, weather specialist,
1st Mst Saucillon, weather specialist.
Probable cause:
It is believed that the loss of power on both right engines was the consequence of a bleed valve failure. Nevertheless, investigations revealed several engine problems on other aircraft operated in the area, probably due to an excessive exposure to a salty environment.

Circumstances:
The airplane was engaged in a weather survey mission over the Baltic sea and was carrying two passengers and a crew of six. While returning to his base at Kaliningrad-Khrabrovo Airport, the crew failed to set the altimeter properly, causing the aircraft to approach the land at an insufficient altitude. In low clouds, the pilot-in-command did not realize his altitude was too low when the airplane struck trees, lost height and crashed in flames 200 meters further onto a school. The airplane was totally destroyed by impact forces and a post crash fire as well as the school building. All eight occupants on board the aircraft were killed as well as 27 people on the ground, 23 children and three adults. Two other children were seriously injured.
Probable cause:
Wrong altimeter setting caused the aircraft to fly at an insufficient altitude. Lack of visibility due to low clouds and poor ATC assistance was considered as contributing factors.

Circumstances:
The crew departed Stalingrad-Gumrak Airport for a regional meteorological mission. While flying in marginal weather conditions at an altitude of 4,000 meters, the captain decided to climb to 5,200 meters and allowed the rest of the crew to execute non-compliant maneuvers. The aircraft went in stall conditions then entered a dive. The captain elected to regain control but the aircraft crashed in a huge explosion in a snow covered field located in Pervoye Maya, about 85 km northeast of Stalingrad-Gumrak Airport. The aircraft disintegrated in impact and all five crew members were killed.
Probable cause:
Due to insufficient experience, the captain decided to allow the crew to engage in a non-manageable situation that led the aircraft to stall and to crash.
