the [instrument] gauges and noticed that the rotor revolutions per minute (RPM) was below the green arc. The student stated that despite his attempts to regain rotor RPM by lowering the collective and adding throttle, he was unable to do so. The student added that he then initiated an autorotation to an open field and land- ed. The helicopter subsequently rolled over on its left side, which resulted in sub- stantial damage.

WPR13LA303 - PRELIMINARY INJURIES: 1 SERIOUS
On June 28, 2013, about 1310 moun-
tain daylight time, a Bell 206L-3 helicop- ter, N868H, was substantially damaged following impact with terrain while maneu- vering near Missoula, Montana. The com- mercial pilot was seriously injured. The helicopter was registered to and operated by a commercial helicopter operator in accordance with 14 Code of Federal Regulations Part 133 as a proficiency check flight. Visual meteorological condi- tions prevailed at the time of the accident, and a flight plan was not filed. The heli- copter had departed the Missoula International Airport (MSO), about 1200. In a post-accident interview with the National Transportation Safety Board
(NTSB) investigator-in-charge (IIC), the pilot stated that while in the process of demonstrating water drops, he made a shallow approach with the long line buck- et attached, and when the bucket entered the water something didn’t feel right; he thought he was settling with power. The pilot further stated that he tried to descend into good air, but when the line tightened the nose of the helicopter dipped forward and down. The pilot revealed that when he pulled aft on the cyclic to correct, he felt the main rotor strike the tail, which resulted in the helicopter spinning to the left. The aircraft subsequently impacted the water and came to rest upright. The helicopter sustained substantial damage to its tail boom, tail rotor drive shaft, and undercarriage.
