S ECO / Cause of occurrence of an accident
3.1 Findings
Crew
Pilot and crew members have valid qualifications to carry out the flight in question, according to the submitted documentation for the execution of rescue flights,
The pilot did not suffer from medical changes that might be causal to the aviation incident in question.
helicopter
had valid documentation and showed no malfunction before and during flight,
before the critical flight, he / she fulfilled the conditions of airworthiness,
The CVR / FDR device has been exposed to large fire and radiant heat, which has seriously damaged memory chips,
The SANAV did not record the whole record after the take-off - it does not include the whole route from take-off to the crash moment but only about 40 seconds of flight, and the Security Commission could not assess the next flight until the helicopter fell,
there were no signs of any mechanical anomalies or impacts on the engine components,
Examining the KEU's research suggests that the technical condition of the helicopter before the accident and during the flight was not the cause of the occurrence of an airplane event. Both engines had normal operation until the event.
3.2 Air Accident Cause
a helicopter helicopter stretch during a flight in a downtrend at ground level,
the pilot did not have a safe height above the surrounding terrain after taking off.
3.3 Matching Causes
Performing rescue flights on demanding mountain terrain under specific conditions (astronomical night).
SAFETY RECOMMENDATIONS
Based on a safety investigation of the causes of the occurrence of an air accident
Bell 429 helicopter
OM-ATR
Which occurred on 07.09.2016
We recommend taking action:
ATE
During the investigation, the "operator" determined an increase in the dimensions of the HEMS landing areas overnight above the dimensions required by Commission Regulation (EU) 965/2012 of 5.October 2012,
Perform additional pilot training to address emergency situations at night in a dedicated workplace designed to simulate changes in global and weather conditions for flights without NVG and NVG.
