Bangkok-Don Mueang

A Boeing 707-300 passenger plane, registered HL7406, was destroyed in an accident in the Indian Ocean, some 100 km off the coast of Myanmar. All 104 passengers and eleven crew members were killed. Korean Air flight 858 departed Baghdad, Iraq on a scheduled service to Seoul, South Korea. En route stops were planned at Abu Dhabi, UAE and Bangkok, Thailand. At 00:01 UTC Flight 858 departed Abu Dhabi, climbing to a cruising altitude of FL370. Last radio contact was at 05:01 UTC when the crew reported that they estimated reaching the TAVOY waypoint over the Andaman Sea at 05:22. Flight 858 was declared missing when it failed to arrive at the destination. On December 13, 1987 a local schooner found pieces of wreckage floating northwest off Tavoy, Myanmar. Korean Authorities, suspecting sabotage after the aircraft became missing, started checking on passengers who disembarked at Abu Dhabi and traced the suspects Mr.Hachiya Shinichi and Miss Hachiya Mayumi to Bahrain where they were apprehended while going through exit formalities at the airport. It was reported that they were found to be holding false Japanese Passports. While being held for interrogation, both committed suicide by taking poison capsules hidden in the cigarettes and Mr.Hachiya Shinichi died. Miss Hachiya Mayumi who survived the attempt was extradited to South Korea. It was reported that the passengers were found to be named Mr. Kim Sung-il and Miss Kim Hyon-hui of North Korean origin. For her role in the bombing Kim Hyun Hui was sentenced to death in March 1989. However, South Korean president Roh Tae-woo pardoned her in 1998.

Following an uneventful flight from Bangkok, the crew started the descent to Phuket Airport by night and good weather conditions. Four minutes after being cleared to descend to 3,000 feet, the pilot reported that he was unable to receive the DME signal. ATC asked the crew if he wanted to conduct a VOR approach to runway 09 but the captain preferred to attempt a visual approach to runway 27. On final, the aircraft struck a hill (800 feet high) and crashed about 18 km short of runway. The aircraft was destroyed and all 11 occupants were killed.

On approach to Bangkok-Don Mueang Airport, the crew encountered poor visibility due to heavy rain falls. Instead of landing on the main runway, the captain attempted to land on a small runway located near the military facilities. Misaligned, the aircraft landed in the adjacent grassy area. Upon touchdown, it lost its undercarriage, slid for few dozen meters, lost its both wings and tail and came to rest with one engine on fire. All eight occupants escaped injured.

On final approach to Bangkok-Don Mueang Airport, the crew encountered engine trouble when the airplane stalled and crashed in a rice paddy field located 12 km from the runway 19 threshold. Three occupants were killed while five others were injured.

After takeoff from Tokyo-Narita Airport while on a cargo flight to Bangkok, the crew reported technical problems with the engine n°3 after the n°6 carbon seal was worn, causing a loss of lubrication. The crew was cleared to return for an emergency landing but weather conditions were marginal and the visibility was limited. Following an approach to runway 16, the airplane was too high and passed over the threshold at a height of 500 feet. The crew continued the descent and the aircraft landed 1,700 meters past the runway threshold and bounced. After reverse thrust was applied on engine n°1, 2 and 4, the airplane veered off runway and struck a manhole, causing the nose gear to collapse. The airplane came to rest and was damaged beyond repair while all three crew members were uninjured. At the time of the accident, wind was from 210 to 350°, 11 knots gusting to 34 knots, visibility 2,200 meters, RVR 900 meters for runway 16 with heavy rain falls and fog.

On 27 April 1980, HS-748 Series 11, HS-THB was on a scheduled domestic passenger flight. The flight operated the route Bangkok - Khon Kaen - Udon - Nakhon Phanom - Udon - Khon Kaen - Bangkok. The departure flight was flight number TG221 which departed Bangkok International Airport at 0101 h, arrived Khon Kaen Airport at 0210 h, departed Khon Kaen Airport at 0233 h, arrived Udon Airport at 0251 h, departed Udon Airport at 0309 h, arrived Nakhon Phanom Airport at 0349 h. The return flight, flight number TG231, departed Nakhon Phanom Airport at 0408 h, arrived Udon Airport at 0448 h, departed Udon Airport at 0507 h, arrived Khon Kaen Airport at 0532 h, departed Khon Kaen Airport at 0550 h, ETA Bangkok International Airport at 0656 h. At 0559 h, after take-off from Khon Kaen Airport, the pilot reported to Bangkok Area Control Centre that he was climbing to 6 000 ft, ETA Korat at 0626 h, ETA Bangkok International Airport at 0656 h and requested ATC clearance to Bangkok International Airport via W6 - KT - W1 - BKK. Bangkok Area Control Centre cleared HS-THB to Bangkok International Airport via this route, to maintain FL 120 and asked the pilot to report when the aircraft reached FL 120.
- At 0614 h the pilot reported that HS-THB reached FL 120.
- At 0626 h the pilot reported that the aircraft was over KT.
- AT 0627 h Bangkok Area Control Centre informed the pilot that HS-THB was in radar contact, 5 miles northwest of KT.
- At 0642 h Bangkok Area Control Centre cleared HS-THB to descend to 8 000 ft and informed the pilot that the altimeter setting was 1 008 mb. This was acknowledged by the pilot.
- At 0644 h, Bangkok Area Control Centre advised the pilot to contact Bangkok Approach Control on 119.1 MHz.
- At 0644 h, the pilot contacted Bangkok Approach Control and reported that he was maintaining 8 000 ft. Bangkok Approach Control advised the pilot to descend to 6 000 ft and informed him that the altimeter setting was 1 008 mb. This was acknowledged by the pilot.
- At 0648 h Bangkok Approach Control advised HS-THB to descend to 6 000 ft.
- At 0651 h Bangkok Approach Control advised HS-THB to descend to 1 500 ft.
- At 0653 h the pilot reported that HS-THB had reached 1 500 ft.
- At 0654 h Bangkok Approach Control informed the pilot that HS-THB was 7 miles from the Outer Marker and cleared the aircraft to make an ILS approach to runway 21R. This was acknowledged by the pilot.
- At 0656 h Bangkok Approach Control advised the pilot to contact Bangkok Tower on 118.1 MHz but no answer from the pilot was received. Bangkok Approach Control tried to contact HS-THB until 0709 h but no answer was received. HS-THB operated in good weather conditions on both the outbound and return flights until, descending to runway 21R nearly at the airport, it encountered an area of rain. Later, HS-THB lost altitude rapidly. Many things in the passenger cabin fell to the cabin floor. It was raining with hail. Looking through the windows, some passengers saw grey clouds. Then the aircraft could maintain altitude. Thirty seconds later it again lost altitude, more severely than the first time. Finally it crashed into a paddy field and skidded forward about 510 feet. Fire occurred in both wings for a while. The accident site was 8 NM northeast of Bangkok International Airport.

After takeoff from Hong Kong-Kai Tak Airport runway 13, while climbing, smoke was seen from the rear of number 4 engine. The propeller was feathered and the crew contacted ATC. About a minute after takeoff, the crew requested the permission to return for an emergency landing on runway 31. After being cleared to descend to 2,000 feet, the airplane went out of control and crashed into the sea off the Waglan Island. The aircraft was destroyed upon impact and all four occupants were killed. They were completing a cargo flight from Hong Kong to UK with an intermediate stop in Bangkok.

While approaching Don Mueang Airport, the airplane crashed in unknown circumstances in an open field located in Lam Luk Ka, about 15 km east of the airport. All nine occupants were injured and the aircraft was destroyed.

While parked, the airplane was struck by a Royal Thai Force C-47 that just took off with 12 people on board. Both airplanes were destroyed. While the C-123 was empty, five people on board the C-47 were killed, seven others were injured.

Shortly after takeoff, the airplane went out of control and crashed on the tarmac, colliding with a parked Royal Thai Force Fairchild C-123K Provider registered L4K-2/16. Both airplanes were destroyed. While the C-123 was empty, five people on board the C-47 were killed, seven others were injured.
