The Agusta A109C helicopter VT-VKS, suffered an accident during an emergency landing at Birsa Munda Airport at 06:54 UTC. The helicopter was airborne from Birsa Munda for Kuchai helipad under Special VFR conditions at 05:46 UTC with six persons on board, including the Chief Minister of Jaharkhand and two pilots. The flight was uneventful till its arrival overhead Kuchai.
While turning for finals the pilot felt loss in left rudder control. On checking the Tail Rotor (TR) effectiveness, left rudder control was found completely ineffective. The helicopter nose had offset to the right and the pilots were unable to align it with flight path. The PIC decided to return to Birsa Munda Airport for an emergency landing on the runway. He attempted a forward speed landing after trying out several approaches wherein the helicopter started yawing to the right on short finals. It turned through 180 degrees, and continued turning further. The helicopter toppled to its left after impacting the runway surface. It was substantially damaged. The occupants received serious injuries. There was no fire. The accident occurred during daylight.
Probable Causes and Contributing Factors
1 The accident was caused due to the malfunction of TR Pitch Control Mechanism due to unwinding of Ring Nut from Duplex Bearing Support Sleeve in absence of the locking wires.
2 Retention of negative TR blade pitch made pilot handling difficult during the landing.
3 Improper handling of the emergency by the pilot was a contributed factor.
