New Delhi, March 1 -- The VSR Aviation chartered jet carrying Maharashtra's deputy chief minister Ajit Pawar crashed as the crew attempted to land in visibility of 3,000 metres, against a legal minimum of 5,000 metres for visual flight, the preliminary investigation report has stated. All five people aboard the Learjet 45XR - including two pilots, a cabin attendant and two passengers - were killed when the aircraft came down to the left of Runway 11 at Baramati airport, struck trees and was engulfed in fire. The Aircraft Accident Investigation Bureau's preliminary report found that visibility at the time of landing was 3,000 metres and this was conveyed to the pilots. Visual Flight Rules, which govern aircraft not equipped or cleared for instrument approaches, require a minimum of 5,000 metres. "The visibility reported at Baramati at the time of landing of aircraft was well below the minima required for VFR flight which is 5000 meters," the report states. But the report also identified what it called systemic flaws. The figure itself was not formally measured. Baramati has no meteorological facility. Visibility was estimated by a ground instructor manning one of the airfield's two temporary towers, who determined the distance by consulting a hand-drawn chart identifying permanent structures at varying distances around the airfield. That estimate was passed to the crew of VT-SSK as they descended toward Baramati. The crew continued the approach. On their first attempt, the pilots reported being "visual with terrain" but unable to sight the airfield itself, and executed a go-around - a procedure in which a crew abandons an approach and climbs away to try again....
