Bombardier Inc. is in talks to sell its CRJ regional jet program to Mitsubishi Heavy Industries Ltd., a move that would end the Canadian industrial champion's involvement in commercial aircraft.

Both sides confirmed they were in discussions after the Air Current reported Wednesday that negotiations were at an advanced stage. The aviation blog said an agreement could be announced as early as the Paris Air Show, which starts June 17.

Mitsubishi said no decision had been made, while Bombardier said any agreement would be subject to further analysis by its own management and due diligence by the Japanese manufacturer.
