Lockheed C-130 Hercules

The aircraft departed Huambo-Albano Machado Airport on an humanitarian mission to Saurimo under call sign UNO806 on behalf of the United Nations Organization. Five minutes after takeoff, while climbing, the aircraft was shot down by a surface-to-air missile and crashed in a field located near the village of Vila Nova, about 40 km from Huambo. The aircraft was destroyed and all 14 occupants were killed.

While parked at Chaklala AFB, the aircraft was destroyed by fire after being struck by another Pakistan Air Force Hercules C-130. The aircraft was empty at the time of the accident.

The crew was engaged in a local post maintenance test flight. While taxiing, the crew lost control of the airplane that collided with a parked Pakistan Air Force C-130. A major fire occurred, destroying both aircraft. All five crew members were killed while the second aircraft was empty.

The four engine aircraft departed Elefsis AFB near Athens on a short flight to Tanagra AFB, carrying five crew members. The aircraft was dispatched at Tanagra AFB to pick up a contingent of 80 soldiers who should take part to the SAR operations following the crash of an Ukrainian Yak-42 on December 17 in the region of Katerini, Central Macedonia. While cruising in a limited visibility due to foggy conditions, the aircraft struck the slope of Mt Pastra located about 24 km southwest of Tanagra Airbase. The wreckage was found few km southeast of the village of Erythres. All five crew members were killed.

The crew was completing a local training mission at Taipei-Songshan Airport. On approach, the crew encountered poor weather conditions with heavy rain falls. The captain decided to initiate a go-around procedure when control was lost. The aircraft crashed few km short of runway and was destroyed. All eight occupants were killed.

While approaching Niamey Airport, the aircraft went out of control and crashed near the village of Sorey, about 10 km southeast of the airport, bursting into flames. The aircraft was destroyed and all 14 occupants were killed.

The aircraft departed Milwaukee-General Billy Mitchell Airport on a flight to Howard AFB, Panama City, with an intermediate stop in Tegucigalpa, carrying 10 crew members and a load consisting of foods and electronics. At Tegucigalpa-Toncontin Airport, the aircraft landed 2,000 feet past the runway threshold in a 50° flaps down configuration. Unable to stop within the remaining distance, it overran and crashed on a road and a bridge, bursting into flames. Three crew members were killed and seven others were injured.

The aircraft was completing a flight from Dezful to Mashhad, carrying 80 passengers and eigh crew members, most of them soldiers, officers and family members. While descending to Mashhad Airport, the crew informed ATC about the failure of an engine. Shortly later, the aircraft struck the slope of a mountain located in the Mashhad-Neyshabur Mountain Range. The wreckage was found about 24 km west of the airport. All 88 occupants were killed.

Based upon digital flight data recorded (DFDR) information, the mishap aircraft departed Portland IAP at 1720 PST on 22 Nov 96 on an instrument flight rules (IFR) flight en route to North Island Naval Air Station. The purpose of the sortie was to conduct an overwater navigation evaluation. King 56 began the sortie with a normal takeoff, departure and climbout. One hour and 24 minutes after takeoff in level flight at FL 220 the mishap sequence began with the engineer commenting on a torque flux on the number 1 engine. Nothing on the cockpit voice recorder (CVR), the DFDR, or the survivor’s testimony suggested any unusual events prior to the engineer’s comment. Over the next three minutes, the operations of all four engines became unstable and eventually failed. Crew actions during these critical three minutes are known only by verbal comments on the CVR and the survivor’s testimony. The following discusses what we know of those actions. The engineer called for n°1 propeller to be placed in mechanical governing. This would normally remove electrical inputs to the propeller through the synchrophaser. The pilot then called for all four propellers to be placed in mechanical governing. This action was consistent with treating this emergency as a four-engine rollback. There is no indication on the DFDR or the CVR as to whether or not the crew selected mechanical governing on any of the remaining three propellers. At the same time the crew was analyzing the emergency, they also declared an in-flight emergency with Oakland ARTCC and turned the mission aircraft east to proceed toward Kingsley Field, Klamath Falls, OR, approximately 230 miles away and approximately 80 miles from the coast. The Radio Operator radioed the USCG Humboldt Bay Station and notified them of the in-flight emergency. During the turn toward the shore the number 3 and number 4 engines once briefly recovered most of their torque. These increases are recorded by the flight data recorder. When the RPM on number 3 (the aircraft’s last functioning engine) finally decreased below 94% RPM the last generator producing electrical power dropped off line due to low frequencies. As a result, at 1846 Pacific Standard Time all electrical power was lost. After a brief period, power was restored to the equipment powered by the battery bus. From this point on, the aircraft glided to the attempted ditching. There is no record of that portion of the flight, except the survivor’s testimony.The outboard wing sections and all four engines separated from the center wing section that in turn separated from the fuselage. Subsequently, the engines and fuselage went straight to the ocean floor at a depth of approximately 5500 feet. The outer wing and the center wing sections floated on the surface for several days and sank more than 50 nm from the impact location. The radio navigator was rescued while 10 other crew members were killed.

The aircraft departed Jackson Hole Airport at 2245LT on a flight to New York-JFK, carrying eight crew members and a U.S. Secret Service agent. The purpose of the flight was to transport a U.S. Secret Service communications vehicle to New York after President Bill Clinton spent some vacations in Jackson Hole. Five minutes after takeoff, while climbing by night, the four engine aircraft struck the slope of Mt Sleeping Indian (Mt Sheep - 3,427 metres high) located about 18 km southeast of the airport. The aircraft disintegrated on impact and all nine occupants were killed.
