Spring 2020

 Spring is coming and it is getting busy with a few wing repairs, sailplane projects, wiring and panel upgrades and new 180 projects on the horizon. 

 2019 winter News

  Winter has come and it seems that I am keeping busy on my own projects and those of others. Every time a nice day rolls along my pace seems to pick up on my own plane. Lots of Jobs in the Q and some new opportunities are on the horizon for 2020.  As always Bentley Air is looking foreword to many adventures this summer with the family and my 180 with plans to visit the Idaho back country and soaring the local mountains as much as time permits.
