On Monday 30 June 1941, in Chokurdakh on the Indigirka River, a PS-7 seaplane of Dalstroy aviation had an accident during take-off. No one was injured in the accident.
Investigation and cause
Causes
The person responsible for the accident was named as the chief of Chokurdakh airfield, D. I. Mikhaylov, who violated the "Manual of Flight Service on the Marine Lines of the Civil Air Fleet", since he did not organise an inspection of the airport's water area before the aircraft's take-off.
