McFarlane Aviation, a Victor Sierra company, is pleased to announce the acquisition of three Supplemental Type Certificates (STCs) from P. Ponk Aviation, a respected developer of high-performance upgrades for legacy Cessna aircraft.

P. Ponk’s STCs have long enhanced the performance and reliability of Cessna 170, 180, 182, 185, and 206 models. The acquisition complements McFarlane’s extensive line of PMA airframe parts for these same aircraft and reinforces its commitment to supporting the general aviation community.

Norma Knopp, Co-Owner of P Ponk Aviation, states “It is with great sadness that I announce the recent passing of my husband and partner Steven Knopp.  He would want our customers – our friends – to continue receiving P Ponk parts with the same product support and service they have come to depend upon.  I am  thrilled to partner with McFarlane Aviation to continue building on the legacy that P. Ponk has established over the years.  Our STCs have a long history of improving performance and reliability for aircraft owners, and working with McFarlane ensures that tradition will continue.”

“These proven designs align perfectly with McFarlane’s focus on supporting legacy airframes with high-quality, cost-effective solutions,” said Mike Polanis, President of McFarlane Aviation. “We’re proud to continue P. Ponk’s tradition of innovation and deliver ongoing support to Cessna owners and maintenance professionals.”

The acquired STCs include:

  • PSK1101 – Main Landing Gear Kit (Cessna 170, 180, 185, L-19)
  • PPA1201 – Inboard Landing Gear Attach Angle (Cessna 170, 180, 185)
  • PPA1301-1 / -2 – Outboard Gear Box Brackets, LH/RH (Cessna 170, 180, 185)
  • PPA1401 – Rudder-Elevator Hinge Bearing (Cessna 180, 182, 185, 206)
