Analysis

 

 

 

The flight instructor reported that during an instructional flight, he and his student were approaching a ridge line to conduct a practice pinnacle landing. The student pilot stated that as they were over the ridge line, the helicopter was struck by a wind gust, and it yawed to the right. He added left anti-torque pedal to correct the yaw, then the low RPM horn sounded, and the instructor took the flight controls. He lowered the collective and added forward cyclic to move away from terrain, however the helicopter landed hard in the snow and rolled onto its right side. The tail boom was substantially damaged. The instructor reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation.

Investigation Docket:

The National Transportation Safety Board (NTSB), established in 1967, is an independent federal agency mandated by Congress through the Independent Safety Board Act of 1974 to investigate transportation accidents, determine the probable causes of the accidents, issue safety recommendations, study transportation safety issues, and evaluate the safety effectiveness of government agencies involved in transportation. The NTSB makes public its actions and decisions through accident reports, safety studies, special investigation reports, safety recommendations, and statistical reviews.

The Independent Safety Board Act, as codified at 49 U.S.C. Section 1154(b), precludes the admission into evidence or use of any part of an NTSB report related to an incident or accident in a civil action for damages resulting from a matter mentioned in the report. A factual report that may be admissible under 9 U.S.C. § 1154(b) is available here.
