Calcutta

The single engine aircraft departed New Delhi at 0842LT on an ambulance flight to Bangkok with two pilots and three doctors on board. A refueling stop was completed at Calcutta Airport. At 1903LT, en route to Bangkok-Don Mueang Airport, the crew contacted ATC and requested permission to divert to Kamphaeng Saen Airport due to an emergency. The permission was granted and the crew initiated the descent when the aircraft disappeared from radar screens at 1916LT. The burned wreckage was found an hour and 30 minutes later, at 2048LT, in a wooded area located few km from runway 22L threshold. All five occupants were injured while the aircraft was destroyed. Few hours later, the copilot died from his injuries.

While descending to Calcutta-Dum Dum Airport, the crew encountered poor weather conditions over the border with Bangladesh when control was lost. The airplane crashed in an open field located in Khulna, some 55 km southeast of Dum Dum Airport and was destroyed upon impact. All 44 occupants were killed.

Indian Airlines Corporation, Caravelle, VT-DPP, while on scheduled domestic passenger service from Calcutta Airport to Palam Airport on 15 February 1966, undershot the runway while attempting to land under conditions of poor visibility due to fog at Palam, with the result that it struck a cement pillar and subsequently several other obstructions until it came to rest on its belly near the threshold of the runway in use. Fortunately, all crew and passengers were able to get out before the aircraft was consumed by the fire which had broken out as a result of the earlier impact with obstructions. Some of the passengers received injuries and burns of varying degrees. Unfortunately, two passengers succumbed to their injuries subsequently. The aircraft was completely destroyed.

On approach to Bombay-Santa Cruz Airport, the crew encountered poor weather conditions with heavy rain falls. On short final, due to lack of visibility, the captain decided to make a go around. While trying to climb, the airplane stalled and crashed near the runway end. All 46 occupants were evacuated while the aircraft was destroyed. It is believed the climb speed was insufficient, causing the aircraft to stall and crash.

Few minutes after takeoff from Silchar Airport, the crew encountered bad weather. The aircraft went out of control and crashed near the village of Santoshpur. A crewman was killed while two other occupants were injured. It appears the accident occurred in poor weather conditions with thunderstorm activity, turbulences and downdrafts.

The aircraft took off from Calcutta-Dum Dum Airport on a scheduled freighter service flight at 0546 hours Indian Standard Time and set course for Guwahati, carrying a crew of three. At 0722 hours, the aircraft contacted Air Traffic Control, Guwahati, on radio telephony and reported flying under visual flight rules, 25 miles away from Guwahati Airport at an altitude of 6 000 feet. The Air Traffic Control Officer on duty passed the altimeter setting to the aircraft, cleared it to descend under VFR and instructed it to call when ten miles from the airport. The aircraft asked for a bearing on frequency 119.7 (Homer) at 0725 hours and a bearing of 045° class 'A' was given. This was confirmed as correct by the aircraft, which also reported being 15 miles from the airport at a height of 3 000 feet at that time. The next contact with Guwahati Tower was at 0727 hours when it reported being at a distance of 10 miles from the airport. Landing instructions were passed to the aircraft and it was asked to call again on joining circuit. There was no further communication with the aircraft. At approximately 0729 the duty officer at the tower noticed black smoke at the top of a patch of fog to the south of the airport. Repeated calls were made to the aircraft on 118.1 Mc/S and 6 440 Kc/S but no response was received. At about the same time persons in Tarapati village saw the aircraft hit some arecanut trees, crash in a field and burst into flames. The captain and the copilot died instantly and the radio officer died en route to the hospital. The aircraft was destroyed.

On final approach, the aircraft was too high and instead of making a go around, the pilot-in-command preferred to land and increased the rate of descent. As the end of the runway was approaching, he raised the undercarriage and completed a belly landing. The aircraft slid for dozen yards before coming to rest. The crew was uninjured while the aircraft was damaged beyond repair.

Shortly after takeoff from Calcutta-Dum Dum Airport, while in initial climb, the port engine failed. The aircraft pitched up, stalled and eventually crashed in a coconut grove located about one km from the airfield. All three crew members and two passengers were killed while six other occupants were injured. The aircraft was destroyed.

Because taxi lights were too dim to use at night, the crew had to use the landing lights while taxiing. Both lights had to be alternated left and right to avoid a meltdown by using a switch behind the captains seat. In a left hand turn the captain took his left hand off the steering wheel to select another landing light. The steering centered, and then the aircraft right wheel bogies ran off the paved surface. Engine power was applied on the two right engines, causing the bogie struts to be forced up and into the wing structure causing much damage.
