Douglas C-47 Skytrain (DC-3)

The crew was completing a local training flight at Yellahanka AFB. After touchdown, the airplane bounced several times, went out of control, veered off runway and came to rest in flames. A crew member was killed while two others were injured.

Flight 739 was a scheduled domestic flight from Bogotá-El Dorado Airport to Pasta-Cano Airport. It was scheduled to depart Bogotá at 0615 hours local time; however, when the crew reported to the Avianca operations office at 0550 hours they were advised that Eldorado Airport was closed owing to thick fog. The airport was reopened to operations at 0750 hours. At about 0830 hours Flight 729 was observed to have commenced taxiing and entered the runway system without having received a clearance to do so. The flight was then given instructions for Runway 30 but further transmissions on 121.9 mc/s were not acknowledged. The flight was subsequently contacted on 118.1 mc/s and the pilot stated he had confused instructions with those given to another aircraft. Take-off was made on runway 10 and when over the threshold of Runway 12 the aircraft commenced a very steep turn to the left in a nose-high attitude. Recovery was effected and the aircraft departed at 0838 hours on a VFR flight plan. After the take-off and climb the flight left the Bogota tower frequency and subsequently contacted Bogota Control and Route Control on 5589 Kc/s. The following position reports were received: 12 500 ft over Guataqui at 0842 hrs, over El Paso at 0902 hrs, over Tuluá at 0924 hrs; at 8 500 ft over Cali, at 0942 hrs, and at 8 500 it over Santander at 0948 hrs estimating Dos Rios at 1014 hrs. No position report for Dos Rios was received. The Tuluá position report was transmitted to Cali as follows: "Tuluá 0922 descending to 8 500, estimating Cali 0942". As the message was very weak the flight was requested to confirm its departure and position; it reported on route frequency 5476.5 KC/S its departure as 0825/38. The flight was then requested to change to VHF frequency 119.1 for radio contact when approaching Cali. It did so but as its signals were not heard it returned to the route frequency stating that it would remain on that frequency since it had not been able to establish contact on the VHF frequency. At 1030 hrs Cali requested information on the flight from Pasto, which reported that the flight had not arrived and there was no information about it. From 1030 hrs onwards the aircraft was called on all available frequencies but no reply was received. An alert phase was declared at 1100 hrs and followed by a distress phase at 1125 hrs. The wreckage of the aircraft was found on 3 January 1967 after 11 days of searching. It had crashed and caught fire at an elevation of approximately 11 600 ft on the southern slopes of Tajumbina Peak (elevation 13 572 ft) in the El Descanse Police Inspectorate. Coordinates of the site of accident were 1° 20' 30" N 76° 47' 30" W. The accident occurred at approximately 0956 hrs on 24 December 1966. The aircraft was destroyed by impact forces and a post crash fire and all 29 occupants have been killed.

Crashed on takeoff for unknown reason. There were no casualties.

Shortly after takeoff from Saigon-Tan Son Nhat Airport, while climbing, the crew informed ground about the failure of the left engine and elected to return for a safe landing. On final approach, as he was unable to lower the landing gear, the captain decided to make a go-around and completed a circuit. While on a second approach, the airplane went out of control and crashed in a rice paddy field located few km from the runway threshold. All 25 passengers and 6 crew members were killed. The left propeller was feathered at the time of impact.
Crew:

Lt Col William Affley Lynch,

The aircraft was used in psychological warfare role. It was fitted with loudspeakers for the delivery of propaganda messages. In flight, an engine failed, forcing the crew to attempt an emergency landing in an open field. The aircraft was damaged beyond repair while all four crew members were rescued.

The aircraft took off from Tenerife airport at 0821. After two minutes of flight the propeller of the left engine began overspeeding. The pilot-in-command applied the normal overspeed procedures, but obtained no response to the manoeuvre. He then actuated the feathering mechanism but this also was ineffective and as the aircraft was losing height he was obliged to ditch it approximately one mile from the coast, since the orography of the locality made a landing impossible. The ditching took place normally. The aircraft remained afloat approximately five minutes and then sank carrying with it one of the passengers who refused to abandon it and who had impeded the evacuation of the other passengers and resisted the efforts of the pilot-in-command and hostess to get him to safety.

While on a training flight, the crew encountered an unexpected situation and was forced to attempt an emergency landing. The airplane went out of control and crashed in flames in a prairie located in Tuzla, southeast of Istanbul. Five crew members were killed and four others were injured.

Crashed in unknown circumstances at Altamira Airport, killing all six crew members.

The crew was completing a local training flight at Santa Lucía Airbase. While flying in the vicinity of the airbase in a limited visibility due to fog, the airplane collided with a Mexican Air Force North American T-28 Trojan registered 793. While the pilot of the Trojan was able to make an emergency landing, the C-47 went out of control and crashed, killing both pilots.

Shortly after takeoff from Al Azaiba Airport, the airplane encountered difficulties to gain height. It struck trees, stalled and crashed 500 meters past the runway end. All 20 occupants were rescued while the aircraft was damaged beyond repair.
