The incident happened around 12.55pm yesterday, November 12, when a gyropcopter he was flying came down in a field near Avoch, on the Moray Firth after it had been flown from Inverness.
The 67-year old man was pronounced dead at the scene.
His identity has yet to be confirmed.
Detective Inspector Brian Geddes of Police Scotland said: “Our thoughts remain with the family and friends of the man who sadly lost his life, and we will have officers providing support at this difficult time.
“Enquiries into the circumstances of the incident are ongoing. We have already spoken to a number of people who witnessed the crash, however, we are appealing to anyone we haven’t spoken to, to get in touch.
“I would also urge anyone who might also have images or video footage of the gyrocopter in the air or during the incident to please contact police either via 101, quoting incident number 1385 of 12 November, or via the online portal set up for this incident.”
The UK Government’s Air Accident’s Investigation Branch announced this morning that they are sending a team to investigate the accident.
A spokesperson from the investigation branch said: “We have been notified of an accident involving a gyrocopter near Avoch, Scotland.
"A team of inspectors are on their way to commence an investigation.”
Police detectives have also set up an online portal to encourage members of the public to submit information.
The Major Incident Public Portal (MIPP) is a website that gives the public access to a form so they can send information directly to the major incident teams based at the Scottish Crime Campus.
