Douglas C-47 Skytrain (DC-3)

Owned by the Colombian Air Force but operated by the Colombian Presidency, the aircraft was completing a charter flight from Popayán to Cali, carrying Felipe Herrera, Director of the Inter-American Development Bank (Banco interamericano de desarollo) and staff. Few minutes after takeoff from Popayán Airport, engine developed trouble and the crew decided to reduce his altitude and to attempt an emergency landing. The airplane crash landed in a prairie located two km from Piendamó, about 22 km northeast of Popayán, and came to rest. While all 12 occupants escaped uninjured, the aircraft was damaged beyond repair.

Prong 33 took off from Phù Cát on the afternoon of the 8th on a planned seven-hour RDF mission. However, just 20 minutes after take off the pilot radioed that he was returning to base because of a problem with the doppler navigation equipment. The aircraft landed safely and although the doppler was fixed, the aircraft weather radar was found to be unusable. Despite bad weather in the flight area, the pilot was told to take off again but to return before dark if the weather worsened. When the aircraft reached its intended area or operations it was found that the weather was too bad to operate safely sot 1st Lt Knight flew towards the coast to return to Phù Cát. The pilot was guided through bad weather towards Phù Cát by the GCA controller but during the approach, 1st Lt Knight reported an inverter fire followed by the loss of his gyros and attitude indicators. The GCA controller gave instructions to direct the aircraft to the airfield but radio and radar contact was lost during the approach. Search operations were hampered by bad weather and it was not until 12 October that the wreckage was located by a SAR helicopter about 15 miles southeast of Phù Cát. All six crew members were killed.

The airplane departed Londrina Airport at 1833LT on the last leg to São Paulo-Congonhas Airport on a flight from Campo Grande to São Paulo. About 50 minutes into the flight, the crew encountered technical problems and was forced to shut down the left engine and to feather its propeller. The captain was then cleared to return to Londrina for a safe landing as an emergency landing at Ourinhos Airport was not possible as it was not lighted at night. On final approach to runway 12 at Londrina Airport, the airplane went out of control and crashed in flames less than two km from the airfield. A passenger was seriously injured while 19 other occupants were killed. Few hours later, the only survivor died from his injuries.
