Changing the prop on an EASA aircraft

[wrench1]

BB:

Yes, but…

Since the TCDS doesn’t differentiate between the -0-60 and -0-62 versions you can use that “62” prop on your plane. But you could also adjust your “60” prop toward a “62”.

You might gain better cruise, but you’ll lose a bit of climb also. It is what it is.

The Archer IIs are all under the same TC model variant. Basically the "same" plane.

So while you could physically tweak your ’77 model toward a ’78 model, you’ll be hindered by RPM limits and performance charts for your serial number aircraft. Ironically, TCDS Note 11 and 24 allows a ’78 model owner to remove his spinner and some fairings effectively slowing the aircraft down to a ’77 model speed.

Maybe look for a STC’d Fairing Kit that has a supplement allowing the use of the ’78 Archer limitations??

Maybe post on the US Piper Owners forum for some input?

Contact Piper itself. Maybe they have a Service Bulletin or Letter that provides a means to get the ’78 model performance out of a ’77 model???

Then again… you can always upgrade to an Aero L-39 for improved cruise performance….

PS: I was told there is a possible Hartzell STC prop option for a PA-28. Cheaper than MT??
