The Indian Airlines Flight 257 (flight number IC257 ) was a domestic flight of the airline Indian Airlines from Kolkata Airport to Imphal Municipal Airport .

plane
The aircraft involved in the accident was a Boeing 737-2A8 Advanced, which was 13 years and 9 months old at the time of the accident. The machine was assembled at the Boeing plant in Renton, Washington , and made its maiden flight on November 17, 1977, before being delivered to Indian Airlines in the same month. The aircraft had the factory number 21497, it was the 504th Boeing 737 from ongoing production. The machine was certified with the aircraft registration VT-EFL . The twin- engined , narrow -body aircraft was equipped with two Pratt & Whitney JT8D-17A engines. At the time of the accident, the machine had completed 29,729 operating hours in 33,574 take-offs and landings.
On January 12, 1978, the same machine on Indian Airlines Flight 117 was involved in a fatal incident when a person was caught and killed while landing at Hyderabad Airport .
the accident
The flight started at Calcutta Airport at 11:54 a.m. and initially went without incident. The flight time should be 60 minutes. At 12:34 pm, the descent began to Imphal . The visibility at this point was 7 kilometers. The crew was cleared to descend from an altitude of 29,000 feet (approximately 8,840 meters) to 10,000 feet (approximately 3,050 meters). Air traffic control lost radio contact with the aircraft at 12:45 p.m., at which point its altitude was 4900 feet (approx. 1500 meters) according to the ILS radar. It turned out that the pilot had flown the machine 23 miles southwest of Imphal into the Thangjing hills. All 69 occupants were killed in the accident.
Cause of accident
The investigators found the cause of the accident to be an error on the part of the pilot in charge who did not follow the flight plan and the map for the ILS approach during the approach. As a result, he was not aware that the premature descent to 10,000 feet and the unannounced flying of a right turn would lead to a shift in the reference times, which would lead him astray into a hilly area.
Salvage
The search for the wreck and possible survivors was made difficult by the weather conditions and the muddy and hilly terrain. Ultimately, all 69 inmates could only be rescued dead.
consequences
Indian Airlines paid the families of each adult crash victim ₹ 500,000 Indian rupees and ₹ 250,000 for the child on board.
