Scheduled Revenue Flight

The crew was performing flight SU831 from Moscow-Bykovo to Simferopol with intermediate stops in Chernigov and Kirovograd. En route, he encountered turbulence while cruising in poor weather conditions. While cruising at an altitude of 2,700 meters, the crew requested to ATC the permission to modify his altitude but this was denied due to heavy traffic. Despite he was uncleared, the captain started to climb in marginal weather conditions. Shortly later, at a height of 2,950 meters, the II-14M collided with a Soviet Air Force AN-12BP registered CCCP-08525. En route from Kedainiai (Lithuania) to Ryazan, this aircraft was carrying 91 soldiers and a crew of 5 back to their base, and was the third AN-12 of a formation of three. The collision occurred when the top of the tail of the AN-12 struck the base of the fuselage of the II-14. Both aircraft went out of control, dove into the ground and crashed in a field, 800 meters from each other. All 120 occupants on both aircraft were killed.

Following an uneventful flight from Mexico City, the crew started the descent to Monterrey-General Mariano Escobido Airport. In a visibility reduced by heavy rain falls, the crew initiated a turn to the left to intercept the glide. After passing over the Monterrey VOR, the aircraft descended with a rate of 1,500 feet per minute when, at a speed of 250 knots, it struck the slope of Cerro del Fraile located some 23 km from the airport. The aircraft disintegrated on impact and all 79 occupants were killed. The wreckage was found at an altitude of 1,800 meters few hours later.

On final approach to Reggio de Calabre Airport, the pilot-in-command failed to realize his altitude was insufficient when the right main gear struck a concrete wall located along the Agata River canal. The approach was continued when upon touchdown, the right main gear collapsed. Out of control, the airplane crash landed, lost its tail and came to rest on runway 15. A passenger was killed while nine others were seriously injured.

While parked at Asunción-Presidente Stroessner Airport, the airplane was partially destroyed after being collided by a Pilatus PC-6 that crashed on takeoff and burned. Two of the four occupants on board the PC-6 were killed. The CV-240 was empty at the time of the accident.

At approximately 1935 hours EST on 6 May, 1969 an Aero Commander 500S aircraft, registered VH-EXT, struck the ground and crashed 2 miles west of Warracknabeal Aerodrome, Victoria, while making an approach to land at that aerodrome. The aircraft was owned and operated by Executive Air Services Pty. Ltd. of Melbourne and at the time of the accident it was engaged on a scheduled passenger commuter service between Essendon and Warracknabeal. The pilot, Allan James WALKER, and one passenger received minor injuries. A second passenger, the only other occupant, was seriously injured. The aircraft was virtually destroyed by impact forces. The pilot, aged 28 years, held a Current Commercial Pilot Licence, which was endorsed for the Aero Commander type of aircraft. He was the holder of a Class One Instrument Rating and this rating had been renewed after a flight test on 2 April, 1969. His total flying experience amounted to 5427 hours and of this, 966 hours had been flown on Aero Commander aircraft. He had recorded totals of 335 hours of instrument flying and 292 hours of night flying. The aircraft was operating under a current certificate of airworthiness and there is no evidence to indicate that the aircraft was other than in an airworthy condition. There is no evidence that the gross weight of the aircraft and the position of the centre of gravity were other than within the specified limits throughout the flight. The weather at Warracknabeal at the time of the accident was fine. There was no cloud and the wind was from the south east at 10 to 15 knots. The night visibility, that is, the distance at which prominent lighted objects could be seen and recognised, was reported to be 20 miles but it was a very dark night and there was virtually no visible horizon. The aircraft departed Essendon at 1836 hours using the procedures applicable to flight under the Instrument Flight Rules. The night to Warracknabeal at 6,500 feet was uneventful and the pilot commenced descent when the aircraft was approximately 40 miles from that destination. During the descent he observed the lights of the town of Warracknabeal and the lighting at the aerodrome. After entering the circuit the pilot commenced a downwind leg for a landing towards the east on runway 08. He made a left turn onto base leg and noted the indicated altitude as 1, 000 feet and at that altitude the clearance between the aircraft and the local terrain should have been slightly more than 600 feet. On the base leg of the circuit the pilot was unable to see the runway lights and being unsure of his position, he elected to conduct a go around. He did not retract the undercarriage, which had been extended earlier in preparation for landing, and the pilot continued the second circuit at 1, 000 feet indicated altitude rather than climbing to establish 1, 000 feet terrain clearance which would have been the normal procedure. He flew over the non-directional beacon, which is located approximately 300 yards north of the western end of the runway on which he intended to land arid he then positioned the aircraft for the downwind leg of the circuit.

On final approach to Irkutsk-Intl Airport, the airplane crash landed 600 meters short of runway threshold and was damaged beyond repair. There were no casualties.

Flight 160 was a scheduled international flight from Buenos Aires, Argentina to Santiago, Chile. The aircraft took off at 2356 hours GMT from Ezeiza Airport, with an IFR flight plan for airways AJG 82 and UG-14, and left the Buenos Aires terminal area via the Mariana intersection, its route taking it over Junín, Villa Reynolds, El Pencal, Mendoza, Juncal and Tabón. The flight level was 310 (31 000 ft). Before flying over Juncal, the aircraft was cleared by the Mendoza Control Centre to descend and maintain flight level 260 (26 000 ft) and after passing Juncal, it was cleared by the Santiago Control Centre to descend and maintain level 250 (25 000 ft) and to pass the Tab6n NDB at flight level 150. It was also given the Santiago weather report, announcing 4/8 nimbostratus at 450 m and 8/8 altostratus at 2 400 m. At 0135 hours, the aircraft passed over Juncal at flight level 260 and then left this level for FL 150; it gave 0142 hours at its estimated time of passage over Tabón NDB and subsequently reported that it was passing through FL 180 (18 000 ft). At 0141 hours, the aircraft passed Tabón NDB and left FL 150 for FL 70 (7 000 ft) and gave 0142 hours as its estimated time of arrival over Colina NDB. Prior to that, Santiago Centre had cleared the aircraft to FL 70 at the Pudahuel Airport ILS outer marker. The aircraft subsequently reported to the Control Centre that it was passing through FL 70; the Centre acknowledged receipt of the message and cleared the flight to make an ILS approach and to change to frequency 118.1 for communication with the Pudahuel Control Tower. The aircraft passed over Colina NDB at about 5 500 ft and continued to descend intercepting the ILS (glide slope) beam at about 4 500 ft, one min 20 sec after passing FL 70. It continued its descent at a rate of about 1 500/2 000 ft/min and descended below the minimum height of 2 829 ft at the outer marker without either the pilot or the co-pilot noting this and on apparently correct indications from the Flight Director. The aircraft continued descending and passed below the minimum height of 1 749 ft published for Pudahuel Airport when suddenly the warning light on the radio altimeter lit up. At this very moment the aircraft levelled off, but its wheels touched the ground and it landed in a field 2 kms north of the ILS outer marker, suffering heavy damage, but without serious injuries to passengers or crew. The accident occurred at 0144 GMT on 28 April, 2144LT on 27 April.

On final approach to Takoradi Airport, both engines stopped simultaneously. The pilot-in-command elected to make an emergency landing when the airplane crash landed few km short of runway threshold. A passenger was killed while few other passengers were wounded, some of them seriously.

For unknown reason, the airplane landed on its left main gear first on runway 07 at Phan Thiêt Airport. After touchdown, control was lost. The airplane veered off runway to the left, struck an earth mound and came to rest. All 31 occupants escaped uninjured while the aircraft was damaged beyond repair.

After touchdown at Manila Airport, the crew encountered difficulties to stop within the remaining distance. The airplane overran, lost its undercarriage and came to a halt 75 meters farter. All 31 occupants escaped without injuries while the aircraft was damaged beyond repair.
