Circumstances:
The aircraft was performing a special flight from Berberati to Bambari with an intermediate stop at Bangui, carrying a crew of three and Barthélemy Boganda, President of the Central African Republic and five members of his office. He was returning to the capital city after taking part to several discussions in Berberati. About 27 minutes after takeoff from Berberati Airport, while in cruising altitude, the right wing failed and detached. Out of control, the airplane dove into the ground and crashed in the savanna located near Boukpayanga. The airplane was totally destroyed and all nine occupants were killed.
Probable cause:
It is believed that the right wing detached in flight due to a structural failure caused by severe vibrations due to additional engines that were installed on this special Noratlas model.

Circumstances:
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.
Probable cause:
The evidence is insufficient to establish the cause of the accident. There is no indication however that this can be associated either with a technical failure of the aircraft or with a failure of the ground services. Thus it is believed the accident was the result of a controlled flight into terrain.

Circumstances:
The aircraft was on an official government flight from Rome, Italy to Yugoslavia, taking the Under Secretary of Foreign Affairs of Yemen to Belgrade. Four crew and four passengers were aboard. The flight departed Ciampino Airport (Rome) at 1645Z on an IFR flight plan and was to proceed via Viterbo, Pescara and Split to Belgrade. Due to the fact that the aircraft gave an impossible estimate for its ETA over Viterbo, Ciampino Tower, at 1729Z on its own initiative, notified the aircraft that it was on a bearing of 315°, which indicated that it was to the west of Viterbo. At 1736Z, YE-AAB advised it was over the Viterbo NDB giving its ETA at Pescara as 1817Z. At 1738Z the Tower cleared the aircraft to climb from 8,500 feet to 13,000 feet and requested it to transfer from VHF to HF for further en route navigation messages. The aircraft acknowledged, and this was the last effective radio contact. At approximately 1800Z the aircraft crashed on the western slopes of Monte Porretta at a height of 2,690 feet. All aboard were killed and the aircraft was destroyed.
Probable cause:
The accident was due to faulty conduct of the flight. The following factors were reported:
- Inadequately trained crew,
- Faulty use of the radio compass,
- Failure to request assistance of D/F facilities,
- Erroneous estimates,
- The pilot-in-command and the crew had an inadequate knowledge of the Italian and English phraseology to be used in ground-air-ground radio communications,
- Erroneous assessment of adverse weather conditions, particularly at the destination airport, bearing in mind the lack of adequate facilities under such conditions,
- Errors in compilation of the flight plan, error of approximately 12 minutes in estimated time for the Rome-Viterbo segment,
- Inaccurate indication of frequencies available in aircraft, in actual fact, the control frequency of the Rome ACC (120.1 Kc) was not available although it was essential for flight assistance,
- Inadequacy of charts covering the area along the route. It appears that there was no chart of Europe on board and the flight guide which was found in the wreckage was out of date.

Circumstances:
The aircraft, with TAROM color scheme but operated by the Romanian Government, was performing a flight from Bucharest to Moscow-Vnukovo with an intermediate stop at Kiev, carrying a Romanian delegation. The approach to Vnukovo was completed by night and after he cleared the inner marker, the pilot established a visual contact with the runway lights and continued the approach. At this time, he was contacted by ATC who instructed him to maintain level as his altitude was insufficient. Shortly later, at a height of about 10 to 15 meters, the airplane struck trees and crashed in a wooded area located 500 meters short of runway and 130 meters to the left of the extended centerline. Three crew members and one passenger, the Romanian Minister of Foreign Affairs Gregore Preoteasa were killed while 12 other occupants were injured, among them the futur President Nicolae Ceaucescu.
Probable cause:
The accident was the consequence of a succession of errors on part of the flying crew during the final approach that was continued at an insufficient altitude. The pilot-in-command took the decision to continue the approach procedure despite a warning message from ATC and because he established a visual contact with the runway lights. Due to low visibility and an insufficient height, this led the aircraft to struck trees and to crash. A lack of training and competences analysis was considered as a contributing factor.

Circumstances:
Christened 'Mount Pinatubo', the airplane departed Cebu City past 0130LT bound for the capital city, carrying journalist, members of the government and Ramon Magsaysay, President of the Republic of The Philippines. While climbing by night, the right engine lost power then failed. The crew was unable to maintain a safe altitude when the airplane struck the slope of Mt Manunggal located about 35 km northwest of the Airport. Rescuers arrived on the scene in the early morning and a passenger, a journalist of the 'Philippine Herald' was seriously injured and evacuated while 25 other occupants were killed.
Probable cause:
The accident was the consequence of the failure of the spindle drive shaft on the carburetor that snapped during climb, causing the right engine to fail.
