Aviation Maintenance


Our shop at Midstate Aviation can maintain Part 91 and Part 135 aircraft to include annuals, 100-hours, and routine maintenance.


We have a limited repair station for pitot/static and transponder checks as required by CFR 91.


Our maintenance staff includes an in-house Airframe & Powerplant Mechanic (A&P), certified Inspection Authority (IA), and Piper fleet operator status.


Ed Beeson, Director of Maintenance, has over 30 years of hands on experience and was awarded WA State Division of Aviation: Mechanic of the Year.



Whether you live in central Washington, or just happen to be flying through, the Midstate team is here to help you with your aviation needs.

Open from 8am-5pm Monday through Saturday, closed Sundays.  We offer self-serve 100LL and jet fuel, and have a jet fuel truck available for fueling during business hours.

Feel free to send us an email, or give us a call.

We're happy to answer any questions you may have.
