The Transportation Safety Board of Canada said the USA -registered, single-engine, six-seat Piper PA-32 airplane crashed about 5 p.m. Wednesday in a wooded area of Kingston, Ontario, about 90 miles (145 kilometers) southwest of Ottawa on the Ontario-New York border.
The Houston resident who piloted a plane that crashed in Kingston, Ont., on Wednesday night, killing all seven aboard, had recently purchased the aircraft in Texas, in part to take his family on trips.
Bobomurod Nabiev, identified as this man in a 2013 Facebook post, died along with his wife in the small-plane crash in Kingston earlier this week.
Previous to the crash, there was once communique between the pilot and Kingston Flight Carrier Station.
He said his brother moved to the United States from Uzbekistan at least 15 years ago.
"We were waiting for the call when they landed", said Basti.
"We are in shock".
The Transportation Protection Board in Canada introduced Thursday that 4 adults and 3 kids died within the devastating crash, and 5 of the sufferers have been American citizens.
"All of us are just devastated".
Basti said Oblokulov had "pretty good experience" flying airplanes and the trip was Oblokulov's first time flying in Canada.
A spokesman for Canadian Forces Base Trenton, meanwhile, said a military helicopter dealt with high winds while it searched for the crash site.
Earlier in the day, TSB spokesperson Chris Krepski offered his condolences to the families of the deceased.
"He was very friendly, very outgoing and well-liked", he said "We're all sad any time something like this happens". We need to take the time necessary to document and examine the aircraft.
