Crew on board: 11, crew fatalities: 0, passengers on board: 224, passenger fatalities: 0, other fatalities: 0.
The listed crash cause is human factor. The aircraft departed Istanbul at 1818LT on March 3 on a scheduled flight to Tribhuvan International Airport (TIA), Kathmandu with 11 crew members and 224 passengers .The aircraft started contacting Kathmandu Control from 00:02 hrs to 00:11hrs while the aircraft was under control of Varanasi and descending to FL 250 but there was no response because Kathmandu Control was not yet in operation. The airport opened at its scheduled time of 00:15hrs. The aircraft established its first contact with Kathmandu Approach at 00:17 hrs and reported holding over Parsa at FL 270. Kathmandu Approach reported visibility 100 meters and airport status as closed. At 00:22 hrs the aircraft requested to proceed to Simara due to moderate turbulence. The Kathmandu Approach instructed the aircraft to descend to FL 210 and proceed to Simara and hold. At 01:05 hrs when Kathmandu Approach provided an updated visibility of 1000 meters and asked the flight crew of their intentions, the flight crew reported ready for RNAV (RNP) APCH for runway 02. The aircraft was given clearance to make an RNP AR APCH. At 01:23 hrs when the aircraft reported Dovan, Kathmandu Approach instructed the flight crew to contact Kathmandu Tower. Kathmandu Tower issued a landing clearance at 01:24 hrs and provided wind information of 100° at 03 knots. At 01:27 hrs the aircraft carried out a missed approach due to lack of visual reference. The aircraft was given clearance to proceed to RATAN hold via MANRI climbing to 10500 feet as per the missed approach procedure. During the missed approach the aircraft was instructed to contact Kathmandu Approach. At 01:43 hrs the aircraft requested the latest visibility to which Kathmandu Approach provided visibility 3000 m and Kathmandu Tower observation of 1000 meters towards the south east and few clouds at 1000 ft, SCT 2000 ft and BKN 10,000 feet. When the flight crew reported their intention to continue approach at 01:44 hrs, Kathmandu Approach cleared the aircraft for RNAV RNP APCH runway 02 and instructed to report RATAN. The aircraft reported crossing 6700 ft at 01:55 hrs to Kathmandu Tower. Kathmandu Tower cleared the aircraft to land and provided wind information of 160° at 04 kts. At 01:57 hrs Kathmandu Tower asked the aircraft if the runway was insight. The aircraft responded that they were not able to see the runway but were continuing the approach. The aircraft was at 880 ft AGL at that time. At 783 ft AGL the aircraft asked Kathmandu Tower if the approach lights were on. Kathmandu Tower informed the aircraft that the approach lights were on at full intensity. The auto-pilots remained coupled to the aircraft until 14 ft AGL, when it was disconnected, a flare was attempted. The maximum vertical acceleration recorded on the flight data recorder was approximately 2.7 G. The aircraft pitch at touchdown was 1.8 degree nose up up which is lower than a normal flare attitude for other landings. From physical evidence recorded on the runway and the GPS latitude and longitude coordinate data the aircraft touched down to the left of the runway centerline with the left hand main gear off the paved runway surface. The aircraft crossed taxiways E and D and came to a stop on the grass area between taxiway D and C with the heading of the aircraft on rest position being 345 degrees (North North West) and the position of the aircraft on rest position was at N 27° 41' 46", E 85° 21'29" At 02:00 hrs Kathmandu Tower asked if the aircraft had landed. The aircraft requested medical and fire assistance reporting its position at the end of the runway. At 02:03 hrs the aircraft requested for bridge and stairs to open the door and vacate passengers instead of evacuation. The fire and rescue team opened the left cabin door and requested the cabin attendant as well as to pilot through Kathmandu Tower to deploy the evacuation slides. At 02:10 hrs evacuation signal was given to disembark the passengers. All passengers were evacuated safely and later, the aircraft was declared as damaged beyond repair.

After touchdown, the aircraft encountered difficulties to stop. It overran and went down and embankment before coming to a halt. While the aircraft was destroyed, all 16 occupants were rescued.
Kalinga Airlines
Douglas C-47 Skytrain (DC-3)
During the takeoff run, the captain saw a man crossing the runway and decided to liftoff asap. He pulled on the control column and the aircraft rotated quickly. Unfortunately, the aircraft's speed was too low and it stalled before crashing few dozen yards farther. Two crewmen were killed while a third one was seriously injured. The aircraft was destroyed.
Indian Airlines
Douglas C-47 Skytrain (DC-3)
The landing at Kathmandu-Tribhuvan was completed at an excessive speed. On touchdown, the aircraft bounced several times before landing firmly. After few dozen yards, the pilot-in-command added power in an attempt to go around when the airplane overran and crashed into a ravine. Nineteen occupants were injured while 14 others plus one person on the ground were killed.
Indian Airlines
Douglas C-47 Skytrain (DC-3)
The crew started the descent to Kathmandu in poor weather conditions when the airplane crashed on a mountainous area located about 20 km from the airport. Following a navigational error on part of the pilots, the airplane followed a wrong approach path to Kathmandu Airport and went into the wrong valley. At the last moment, the pilot-in-command made a sharp turn to avoid the mountain but the aircraft stalled due to an insufficient speed and crashed on a rocky slope. The aircraft was destroyed upon impact and all 20 occupants have been killed.
Turkish Airlines - THY Türk Hava Yollari
Vickers Viscount
The aircraft was on a special flight from Ankara to London via Rome with Adnan Menderes the Prime Minister of Turkey and a party of Turkish Government officials on board. The aircraft left Rome at 13:02. TC-SEV called London Airways at 15:56 after passing Abbeville and was cleared by ATC to the Epsom Radio Range station, the holding point for London Airport. Because of poor visibility at destination London (Heathrow) Airport, the London Airport Commandant decided to inform the Turkish captain that he should divert to Gatwick. At 16:21 hrs the aircraft reported over the Epsom range and was given diversion instructions. At 16:27 it left Epsom for Mayfield, the holding point for Gatwick, where it was informed by Gatwick Approach Control that it would be positioned by radar for an ILS approach to runway 09. The latest weather report for Gatwick was given as wind calm, visibility 1.1 nm, mist, cloud 3 oktas at 600 feet, QFE 1036 mb. Over the Mayfield NDB at 4,000 feet the flight was instructed to steer a course of 280 and to descend to 2,000 feet. This was acknowledged. A further descent clearance was given to 1500 feet. The aircraft overshot the centre line slightly as it turned on to the ILS approach path. At 5nm from touchdown, the aircraft affirmed that it could continue on the ILS. TC-SEV was then asked to change to tower frequency and this request was acknowledged. This was the last communication with the aircraft. At a position of some 5 km from the runway threshold and 550 feet to the north of the approach path centre line, the aircraft contacted tops of trees 390 feet amsl at the edge of Jordan's Wood. The aircraft began to disintegrate as it descended through the trees at an angle of about 6 degrees from the horizontal until the wheels made contact with the ground. After rising again slightly the main part of the wreckage came to rest about 100 yards further on and then caught fire. The Prime Minister Adnan Menderes survived the accident with nine other people while 14 other occupants were killed, among them five crew members.
Swiss Dhaulagiri Expedition
Pilatus PC-6 (Porter & Turbo Porter)
The crew was completing a supply mission to the Swiss Dhaulagiri Expedition in the Himalaya Mountain Range and was leaving the Dambusch Pass to return to his base at Pokhara when the airplane crashed on takeoff. The right wing and the propeller were bent. While both crew members were uninjured, the airplane was abandoned in situ. Swiss people returned on site (5,200 meters high) in 1998 to recover the airplane that should repatriated in Switzerland. It is believed that a technical issue was the cause of the accident. Crew: Ernst Saxer, pilot, Emil Wick, copilot.
