A spokesperson with the Royal Canadian Air Force says its too soon to say if there will be any modifications made to the Snowbirds Tutor jets.

Speaking on the NL Morning News, David Lavalee says any modifications to the aircraft used by the Snowbirds for almost 50 years would be done at a higher level.

“Really what we have done is implement largely operational restriction,” he said.

“For example, we’ve implemented some minimum flight speeds and altitudes that the aircraft should be operating at whenever possible. We have also implemented some minimum runway lengths. We’ve also put in some restrictions where only mission essential personnel will be flying in the aircraft.”

He adds the planes will also be subject to more frequent maintenance.

“They are going to be looking at the engines a little more closely, doing a little bit more preventative maintenance and some inspections more often than we normally would,” Lavalee said. “All these things taken together, add up to an ability to reduce risk down to a level where we can allow the fleet to resume flying and get them back up in the air and get them training again.”

The Snowbirds have been grounded since a May 17 crash, though the fleet is expected to leave Kamloops soon after the planes were cleared to fly again.

In teh days after the crash, Prime Minister Justin Trudeau says there are “very good questions” being asked about the safety of the Snowbirds, after a deadly crash in Kamloops on Sunday.

Two Snowbirds Tutor jets will be leaving Kamloops at 9 a.m. tomorrow, September 1, heading back to home base in Moose Jaw, Saskatchewan, subject to weather and operational requirements.
