Our Fleet

MASA operates one of the nicest fleets of gliders and tow planes in the United States. Flight training is done using three two seat gliders, while the club also owns two single seat gliders for the further training of post solo students and the enjoyment of the general membership.
Having an outstanding stable of gliders is only part of M-ASA’s success. You need to have a means to launch the gliders. M-ASA does this using three tow planes. Two Piper PA-25 Pawnees do the majority of the glider launches. A Piper PA-18 rounds out the towing fleet by providing the ability to train tow pilots and maintain proficiency.


Schleicher ASK 21

M-ASA operates two ASK 21s manufactured by Alexander Schliecher GmbH & Co in Germany. These gliders were purchased new from the factory in 2017. M-ASA took delivery over Thanksgiving 2017 and promptly put them into operation that weekend. Their docile handling promises to make these a favorite of our students and instructors for many years to come.
