As a kid I flew for Forest Protection Limited, based in Fredericton, New Brunswick, and at that time the Company was the largest civilian operator of TBM Avengers in the world. I did not fly the TBM - I was what they called a birddog lead.
Due to new rules about spraying insectiside, I believe the Company fllew it's last season in the mid '70s. i have no idea where the fleet if airworth Avengers ended up.
