Circumstances:
The airplane departed Taipei-Songshan Airport bound for Kaohsiung. Fourteen minutes later, while cruising at FL220, radar contact was lost with the airplane and the crew did not send any distress message. The airplane entered an uncontrolled descent, suffered an explosive cabin decompression, partially disintegrated in the air and crashed in Sanyi, in the Miaoli County. Debris scattered on a large area (10 km2) and all 110 occupants were killed, among them the Japanese writer Kuniko Mukōda.
Probable cause:
Extensive corrosion damage in the lower fuselage structures, and at a number of locations there were corrosion penetrated through pits, holes and cracks due to intergranular corrosion and skin thinning exfoliation corrosion, and in addition, the possible existence of undetected cracks because of the great number of pressurization cycles of the aircraft (a total of 33,313 landings), interaction of these defects and the damage had so deteriorated that rapid fracture occurred at a certain flight altitude and pressure differential resulting rapid decompression and sudden break of passenger compartment floor beams and connecting frames, cutting control cables and electrical wiring. And eventually loss of power, loss of control, midair disintegration.

Circumstances:
After takeoff from Kaohsiung Airport, while climbing, the crew encountered technical problems with the right engine. The captain informed ground about his situation and was cleared to return for a safe landing. He quickly realized he could not make it so he reduced his altitude and attempted and emergency landing. While flying a low height over a dense wooded area, the airplane went out of control and eventually crashed in flames in an open field located near Tainan. The aircraft was totally destroyed and all 36 occupants were killed. The aircraft crashed 12 minutes after its takeoff from Kaohsiung Airport, bound for Taipei-Songshan Airport.
Probable cause:
It is believed that the right engine failed in flight. For undetermined reason, the crew was unable to feather the propeller that was windmilling, causing high drag and the loss of control.

Circumstances:
Flight No. 10 operated by Civil Air Transport was a scheduled international flight from Taipei to Hong Kong and return. The accident occurred on the return trip from Hong Kong to Taipei. The aircraft departed Hong Kong at 2018 hours local time. At 2045 hours it reported to Taipei Area Control Centre over Yellowtail, a compulsory reporting intersection, at flight level 29 000 ft. At 2059 hours it reported over Makung VOR, and was then cleared to descend to 11 000 ft. At 2111 hours it reported over Hsinchu (PO) NDB at 11 000 ft and was cleared to descend to 5 000 ft crossing Taoyuan (GM) NDB and to 2 000 ft crossing Linkuo outer marker for a straight-in ILS approach to runway 10. The current Taipei weather information was also given to the pilot at that time. At 2118 hours the aircraft reported approaching Linkuo outer marker at 2 000 ft and was cleared to continue its ILS approach and to contact Taipei Tower. The aircraft reported to Taipei Tower and requested landing instructions. The tower controller advised the pilot to continue his ILS approach to runway 10, gave him the surface wind and the altimeter setting and requested him to report approach lights in sight. The pilot acknowledged all this information. From that moment, even though repeated attempts to contact the aircraft were made by Taipei Tower and Taipei Area Control Centre, no further communication was received from the aircraft. Then, right after, Taipei Area Control Centre was informed that the aircraft had crashed in the vicinity of Linkou, about 8 miles west of Taipei City. Three crew members, 18 passengers and one person on the ground were killed. The aircraft was destroyed. It was found during the investigation that the left hand pilot seat was not occupied by the assigned pilot-in-command, but by another Senior Pilot of Civil Air Transport.
Probable cause:
The "Senior Pilot" who was actually at the controls failed to maintain proper altitude while approaching the Linkou outer marker and the aircraft was far below the required altitude; consequently the aircraft could not intercept the glide path. When the radio altimeter warning light came on, while the aircraft descended to an altitude of 350 ft, the pilot failed to take corrective action in time. The wheels touched the ground and the aircraft rolled on the ground for about 200 metres. The aircraft was then pulled up in the air but it hit trees and a farm house and subsequently crashed. It was concluded that this accident was caused by careless operation in piloting the aircraft. According to the Flight Plan and documents of this flight, the pilot-in-command was properly assigned. Although the above-mentioned "Senior Pilot" held an appropriate licence with a rating for Boeing 727 aircraft, he was neither the assigned pilot-in-command nor a pilot under training on this flight. It was concluded that in allowing him to perform the functions of pilot- in-command, the assigned pilot-in-command of this flight, was also at fault.

Circumstances:
Thai Airways International Flight 601, a scheduled passenger service from Taipei International Airport, Formosa, to Hong Kong International Airport, departed from Taipei at 0540 hours with an estimated enroute time of 1 hour 27 minutes, and an endurance of 4 hours 19 minutes. The flight was made at flight level 260 and was entirely normal except that, because of turbulence expected from a severe tropical storm, the passenger seat belts were on for the majority of the flight. No turbulence of any importance was in fact experienced. At 0638 hours, when approximately 170 miles from Hong Kong, Flight 601 made contact with Hong Kong airways control and received clearance to descend to flight level 70. At 0658 hours they contacted Hong Kong approach control, which later cleared them to descend to 2 500 feet using an altimeter setting (QNH) of 999 mb, and informed them that there was a heavy rain shower at Hong Kong and that the visibility was very reduced to 2 km. The co-pilot flew the aircraft manually from the right-hand seat, whilst the Captain monitored the approach from the left hand seat and handled the R/T communications, the third pilot, who was acting as the system operator, also monitored the flight instruments. Rhe approach controller provided radar guidance to position the aircraft for an ILS approach to runway 31 and when it was at about 8 miles from touchdown, cleared the pilots to contact the precision controller. This controller cleared them to continue their ILS approach, informed them that there was heavy rain at the field and told them the overshoot procedure to be adopted should this become necessary. The aircraft remained well within the approach safety funnel 2° either side of the localiser centerline and 1/2° above or below the glide slope, until 3 miles from touchdown, the PAR controller having provided information on weather, overshoot instructions and distance from touchdown as shown on the R/T transcript at Appendix C. In his 3 miles distance advisory, the PAR controller informed the pilot that he was just a little to the right; this appeared to be corrected and the aircraft returned to the centre line. At about 2 3/4 miles, the aircraft descended momentarily below the glide slope safety funnel but returned quickly towards the glide slope before the PAR controller had made any advisory comment. At 1 1/2 mile the aircraft was again a little right of centre line and at this time also interference from the heavy rain began to obscure PAR reception, firstly in elevation and, shortly after one mile, also in azimuth. Correlation of the flight recorder readout and the R/T transcript indicates that-approximately 2 seconds after receiving the 1 1/2 mile advisory that he was a little to the right, the co-pilot made a left turn of 14°. Eight seconds later, the PAR controller advised him that he was coming back to the centre line and almost immediately he began a right turn of similar dimensions. Five seconds after this, the PAR controller save the 1 mile advisory and the information that the aircraft was going left of centre after which the aircraft increased its rate of turn to the right. On hearing the 1 mile advisory, the captain reinforced it by telling the co-pilot to move to the right and a moment or two later, when looking across the cockpit, saw the sea about 100 ft below through the copilot's side window. He immediately attempted to make a pull-up, but the aircraft struck the surface, bounced slightly, and settled on the water about 3 925 ft before the ILS reference point of runway 31 and about 100 ft left of the ILS centre line. According to the survivors the impact was not unduly greater than that of a heavy landing but the starboard wing and undercarriage broke away, the latter ripping open the underside of the fuselage; in addition, the rear end of the fuselage broke open. As a result of this damage the aircraft sank very rapidly and 14 of the passengers did not escape from the fuselage and were drowned, 6 were dead on arrival at hospital, 4 were missing and later found drowned. The remaining passengers and the crew were rescued by nearby surface vessels and a helicopter.
Probable cause:
The causes of the accident were:
- The pilots did not adhere to the Thai Airways procedure for a 'Captain monitored' approach in bad visibility,
- The captain did not monitor the approach adequately,
- The copilot mishandled the aircraft after descending below minimum altitude,
- Downdraughts may have contributed to the height loss which resulted from this mishandling.
