Investigation team of the Interstate Aviation Committee has completed the investigation of the accident with "Cosmos"
US-15LЗ RA-0412G ultralight trike occurred in 2 km to the south-east from Kezmino locality, Sursky district, Ulyanovsk region (RF) on 29.05.2009.
According to the Investigation team's conclusion:
"Fatal accident with "Cosmos" US-15LЗ RA-0412G ultralight trike occurred due to its collision with forest plantation trees that was caused by untimely climbing maneuver during recovery from "crop-dusting run".
Probably contributing factor could be pilot's performance impairment due to:
– insufficient pilot's training for crop-dusting;
– crop-dusting at the aircraft not certified for this type of aviation works;
– violation of preflight rest schedule requirements by pilot;
– application of banned chemicals during filed treatment;
– pilot operation without personal protective equipment;
– flight operation in brain bucket 5A with lowered color filter".
