The Interstate Aviation Committee Investigation team has completed the investigation of the accident with R-66 RA-06354 helicopter owned by System Leasing 24 CJSC occurred in the Moscow region (RF) on 21.08.2015.

Most probably the accident with Robinson R-66 RA-06354 helicopter was caused by the pilot's control inputs resulted in rotorcraft placing into low-G conditions (the weightless or close to it state) and the right roll development.

The PIC’s actions to recover from a low-G situation were inconsistent with the Pilot’s Operating Handbook provisions, which led to the high vertical speed descent and helicopter impact with ground.

Appropriate safety recommendations based on the investigation results were developed.
