Fall to Winter 2018

  Made it home from AK down the trench and crossing into the US at Dorthy Scott airport, it was a great flight only got stuck once. Now comes the task of working or maybe getting the work. Work is slowly coming in keeping the kids in shoes and a beer in my hand once in a while. In the process of tooling up to rebuild some wings and as always in the hunt for another project 180. Clyde is flying like a he was born on rails and climbs like iron thermal. My hanger is coming together, life is good, besides a great wife and kids what else could a man need when he has a hanger, 180 and all his tools in one place?

 2018 summer News

  John has taken the opportunity to fly a Beaver for a fishing lodge for the summer out of Katmi National Park. He flew his 180 that he just recently rebuilt up the Trench without a hitch. Working and flying the Beaver was somewhat like putting on an old pair of comfortable shoes that have been sitting in the closet for a long time, it feels like you just took them off. It has not been easy though as he spent the first 10 days working on the Beaver, that's what comes with being a mechanic as well. It is also has given him the opportunity to "Dial In" the plane before the season. Float flying is the best and even better when flying a Beaver unless you own a 180 that is....... He will be back in the hanger at the end of September where a customer is waiting on a ground loop repair on his 180. Check the "News" tab on the website for updates from Alaska.
