A stock PA-18 has incredible performance but with the 180hp engine it takes it to a complete other level of performance.

Both conical and dynafocal engine options are approved. Below is a list of the approved engine options:

Conical: C1A, C1C, C1E, C1G, C2A, C2C, C2D, C2E, C4P

Dynafocal: A1A, A1D, A1P, A2A, A2D, A2E, A4D, A4N, A4P

Any other O-360 series engine that is converted to one of the above models in accordance with Lycoming instructions is able to be used with this STC.  The STC is for paperwork only.  The purchase of this STC includes SA02751CH (McCauley Propeller 1A200FA) which is also paperwork only.

The STC requires Rubbert Aircraft Services Lower Cowling STC (SA03035CH) and Engine Baffle STC (SA03034CH) to be installed. Airforms engine baffling is now approved as an alternate to the Rubbert baffling. Since the Airforms baffling is PMA’d, we just approved the installation of their left hand oil cooler baffle. The rest of their baffling is ok to install under their authorization in place of the Rubbert baffling.  Please contact Rubbert Aircraft Services at 701-847-3008 for current pricing on all of their parts and STC’s or Airforms for their current pricing.

Customers who wish to save $100, can get a discount by mailing us a check for $1500.  The website will NOT take off the discount of a $100 on your invoice, we will do that on our end when we process your order.  Please let us know if you have any questions!

**We have worked with Rubbert Aircracft Services for a many years. Randy Rubbert, owner of Rubbert Aircraft Services, has been making parts for PA-18’s for over 30 years. His cowling, airbox, and baffling makes the 180hp conversion really complete, and many people have gone to Randy for their 180hp conversion parts. His parts have long been known as excellent quality and a favorite in the PA-18 community. We are happy to work with Randy and offer this modification for all model PA-18 and PA-19 aircraft.
