'''Indian Airlines Flight 257''' was a flight on 16 August 1991 that crashed on its descent into [[Imphal]], [[India]], killing all 69 occupants.
==Accident==
The flight, operating on the [[Kolkata|Calcutta]]-Imphal route, crashed into Thangjing hills, about {{convert|37|km|mi nmi|abbr=}} south-west of the Imphal airport. The aircraft had started the short flight from Calcutta around 12:00 pm and it began a descent into Imphal airport at around 12:41 pm. Visibility at that time was {{convert|7|km|mi nmi||abbr=}}. Imphal airport lost contact with the aircraft just after 12:45, at {{convert|1500|m|ft}} altitude on the Instrument Landing System. The search and rescue efforts were hampered by bad weather conditions and a hilly and slushy terrain.<ref>{{Cite web|url=https://parliamentofindia.nic.in/ls/lsdeb/ls10/ses1/18190891.htm|title=Accident of Indian Air Lines Aircraft near Imphal|date=1991-08-18|website=parliamentofindia.nic.in|access-date=2019-06-30}}</ref>
==Investigation==
The probable cause of the crash was attributed to an "error on the part of the Pilot-in-Command in not adhering to the operational flight plan and ILS let down chart and not realizing that his early descent to {{convert|10000|ft|m|-3}} and turning right for outbound leg without reporting overhead VOR would result in loss of time reference and as such misplace him in the hilly terrain. The Pilot-in-Command's action may have been influenced by his extreme familiarity with the terrain".<ref>{{Cite web|title=ASN Aircraft accident Boeing 737-2A8 Advanced VT-EFL Imphal Municipal Airport (IMF)|url=https://aviation-safety.net/database/record.php?id=19910816-1|last=Ranter|first=Harro|date=|website=aviation-safety.net|publisher=Aviation Safety Network|access-date=2019-06-30}}</ref><ref>{{Cite web|title=Accident to Indian Airlines Boeing 737 Aircraft VT-EFL on 16th August 1991 Near Itnphal, Manipur|url=https://dgca.gov.in/digigov-portal/Upload?flag=iframeAttachView&attachId=130615405&mainAccidentReports|last=|first=|date=|website=dgca.gov.in|publisher=[[Directorate General of Civil Aviation (India)]]|format=PDF|access-date=2020-05-25}}</ref>
