A Cessna 208B Grand Caravan passenger plane, registered VT-NES, sustained substantial damage in a landing accident at Lengpui Airport (AJL), India. The aircraft was operating a non scheduled flight from Imphal to Lengpui with ten persons on board including the pilot. The aircraft took off normally from Imphal at 10:00 hrs and subsequently came in contact with ATC Lengpui at 10:23hrs. ATC Lengpui conveyed the latest available weather with visibility as 4500 m. The pilot requested special VFR which was approved by the tower controller. Visibility further dropped to 2000 m and the pilot preferred to enter a holding pattern, in coordination with ATC at 10 miles maintaining visual separation with terrain at an altitude of 6500 feet. The pilot thereafter without any communication with ATC reported downwind for runway 17 and subsequently reported for final. When the aircraft reported final, the controller after sighting the aircraft gave the landing clearance with wind as calm and runway surface wet. The aircraft touched down well past the threshold at a high speed with a remaining distance in which it was impossible to stop the aircraft. It climbed a 10 feet high platform constructed to install the Localizer antenna at the end of runway 17. As the speed of the aircraft was high, it continued past the localizer platform and fell in a ravine approximately 60 feet deep. All 9 passengers and the pilot escaped unhurt. There was no fire. Cause of the Accident: “The cause of the accident was inadequate skill level of the pilot to execute a safe landing during marginal weather condition.”
