WAKE FOREST, N.C. – Plane Dynamix has acquired Art Mattson’s line of FAA approved airframe and engine STCs for Piper PA-28 series aircraft.
“Art was synonymous with improving Cherokee performance and safety and we are thrilled to be able to bring his creations back to the Piper community,” said Dan Benedix, pilot partner, Plane Dynamix. “Having his daughter, Pam join us and keep the Mattson name associated with these outstanding STCs just felt right. We couldn’t imagine trying to do it without her.”
“I’m very excited to have my father’s legacy carried on by someone with a great passion for aviation,” Mattson said.
Benedix said that many of Mattson’s STCs are available for immediate shipment. These STCs include:
- Gap seals, which improve the laminar air flow over the wing and stabilator.
- Engine upgrade certificates that provide the industry’s only unrestricted 10-horsepower upgrade for the Lycoming O-320.
- Propeller tip modifications for the Sensenich propellers. This mod reshapes the tips to reduce drag and increase the propeller blade’s efficiency.
He also said that Mattson’s line of Vortex generators and stabilator tips for improved wing and stabilator performance are also available for pre-orders, with anticipated delivery dates in early December of this year.

Wouldn’t it be both more effective and cheaper to sell the Cherokee and use the proceeds to just buy a Bonanza?
Not when you start feeding and maintaining the Bonanza.
You can feed and maintain the Bonanza with the ongoing cost of the STC’s.
But I get your drift Greg.
Most STC’s are a onetime expense, not recurring.
I’ve owned several Cherokees and a Bonanza. They are very very different airplanes. In my experience a Bo will cost lots lots more to feed and maintain. But it is a first class ride!
