Douglas DC-6

On final approach to Mérida-Licenciado Manuel Crecencio Rejon Airport, the four engine aircraft stalled and crashed few dozen yards short of runway threshold. All 29 occupants were injured and the aircraft was destroyed.

The crew was completing a local training mission at Oakland International Airport. After touchdown, the pilot-in-command started the braking procedure when control was lost. The airplane veered off runway before coming to rest. While all four crew members were uninjured, the aircraft was damaged beyond repair.

After touchdown at Al Hudaydah Airport, the crew started the braking procedure when control was lost. The airplane veered off runway, lost its undercarriage and came to rest. There were no casualties but the airplane was written off.

The approach to Tegucigalpa-Toncontin Airport was completed in strong NNE winds. After touchdown on runway 01, the airplane went out of control, veered off runway, lost its undercarriage and came to rest in flames in a drainage ditch. All three crew members escaped uninjured while the aircraft was destroyed by fire.

While cruising in marginal weather conditions on a cargo flight from Beirut to Frankfurt, the four engine aircraft disappeared from radar screens after it struck the slope of Mt Parnon located in the Peloponnese province, at the border between Laconia and Arcadia districts. The wreckage was found about 27 km east of Sparta. All five crew members were killed.

The aircraft had taken off from Brussels at 0010 hours GMT on 18 February 1966 on a cargo flight to Milan-Malpensa, Italy, to transport 214 calves. The flight was routine until the aircraft arrived over the Saronno VOR/NDB at 0148 hours. It was then cleared by Milan ACC to fly directly to the Malpensa radio beacon with a 6 000 ft "clearance limit" and to contact Malpensa APP directly. The aircraft was duly transferred to this latter unit at 0150 hours. At 0153 hours the aircraft was over NDB Malpensa at 6 000 feet and was cleared by Malpensa APP to carry out a STANDARD/ILS (SIA) approach procedure to runway 35R. The aircraft was also provided with complete meteorological data for Malpensa Airport; runway visibility was given as 250 m. The aircraft left the 6 000 ft level at 0153:20 hours outbound on track 1550 as specified in AIP/ITALY MAP/050/1. At 0157:33 hours the pilot reported on approach inbound (352°) at 4 000 feet. At 0159:49 hours the Malpensa airport PAR controller provided the pilot with the current parameters: distance 7 NM/on track/ on the glide path. At 0200:44 hours the pilot reported 2 000 ft at the outer marker. It was cleared by Malpensa APP to land on runway 35R and instructed to report runway in sight. The ground/air/ground communications log indicates that the approach procedure was being carried out correctly and at 0202:50 hours the radar controller informed the pilot that he was over the approach end of the runway. This was the last contact between the aircraft and the control services. The aircraft had actually carried out a night-time final approach phase procedure in extremely critical visibility conditions because of fog, and in such conditions it had crossed the threshold of runway 35R deviating about 8° to the right in relation to the runway centre line; it then continued alongside the runway for about 2 400 m and struck the top of a group of trees beyond which it crashed to the ground approximately 3 000 m from the runway threshold and 435 m from its centre line. The aircraft caught fire following fuel spillage after impact with the ground. All the occupants were killed and the cargo was destroyed.

During the takeoff roll at Huntsville Airport, when V1 speed was reached, the pilot-in-command started the rotation when the nose gear retracted. The airplane sank on its nose, slid for several yards, overran and came to rest 300 feet further. All 16 occupants were evacuated safely while the aircraft was damaged beyond repair.

Flight 21 was a scheduled domestic flight from Vancouver, British Columbia, to Whitehorse, Yukon Territory via Prince George, Fort St. John, Fort Nelson in British Columbia and Watson Lake, Yukon Territory. At 1442 hours PST, the aircraft took off on an instrument flight plan for Prince George, via Victor 300 and Blue 22 airways. In the vicinity of Hope, north-bound on Blue 22 airway, it was sighted by CPA Flight 22 and communication was established. Shortly afterwards at 1517 hours Flight 21 requested and received clearance to proceed from its position north of Hope direct to Williams Lake, which track would pass to the west of Ashcroft. At 1529 hours, it reported to the Vancouver Air Traffic Control Centre that it had passed Ashcroft at 1527 hours at 16 000 ft and was estimating William Lake at 1548 hours. This transmission was acknowledged by the Vancouver Centre. At 1538 hours, Vancouver Centre called Flight 21 and did not receive a reply. About two minutes later, three "mayday" calls were heard by Vancouver Centre. At approximately the same time a four-engined aircraft, subsequently identified as Flight 21, was observed by witnesses flying in the clear over the Gustafson Lake area about 20 miles west of 100 Mile House, B.C. The aircraft appeared to be in normal flight when an explosion was heard, following which smoke was observed and the tail separated from the fuselage. The main portion of the wreckage assumed a nose down attitude and spiraled to the left until it crashed into a wooded area about 4.5 miles north of Gustafson Lake. The accident occurred at 1541 hours. There were no survivors among the 52 occupants.

During the takeoff roll at Cebu Airport, one the undercarriage failed. The airplane sank on runway and slid for several yards before coming to rest. There were no casualties but the aircraft was written off.

AAXICO Airlines, Inc., Douglas DC-6A, N6579C, operating as AAXICO Flight No. 1416B, a regularly scheduled Civil Air Movement (CAN) cargo flight, crashed during an approach to a landing at Whiteman Air Force Base (AFB), Knob Noster, Missouri, at approximately 0601 c.s.t., on May 18, 1965. The crew of three, the only persons on board, escaped uninjured. The flight scheduled from Hill AFB, Ogden, Utah, to Offutt AFB, Omaha, Nebraska, with several scheduled stops at various Air Force Bases en route, departed Tinker AFB, Oklahoma City, Oklahoma, on an Instrument Flight Rules (IFR) flight plan at 0446 c.s.t., for Whiteman AFB. Shortly after departure the flight canceled IFR and continued in accordance with Visual Flight Rules (VFR). The flight approached Whiteman AFB from the south and was cleared for a straight-in visual approach to runway 36. At this time a line of thunderstorms was located to the west of the field, portions of which were moving across the approach end of the runway obstructing the crew's sighting of the base and runway. The flight continued the approach, encountering heavy rain which reduced visibility to the point that visual contact with the ground was lost. The aircraft struck the trees 4,204 feet short of the runway threshold and 740 feet to the right of the extended runway center-line while on a magnetic heading of 020 degrees. The aircraft continued to the ground, shearing the landing gear, the No. 4 engine and right outer wing panel, and slid approximately 1,200 feet on the bottom fuselage surface. Ground impact ruptured the right wing fuel tanks spilling fuel along the wreckage path which resulted in a ground fire of short duration. The left inboard tanks ruptured causing a fire which destroyed the fuselage interior.
