The International Cessna^® 170 Association

Hello Everyone,

After my plane came out of annual it had a new placard placed next to the tach. "Avoid continious engine operation between 2150 and 2350 RPM" Only issue I have is that I cannot find that in my paperwork. I'm running the C145. Is this corrrect ? If so - I need to make new ones as the white paper stuck to the black overlay looks awful.

Thanks ....

Kyle

What propeller do you have?

George, It's a McCauley 7654

Well, I'd ask the IA why he put it there then. The only restriction on the McCauley DM/MDM (1A170) is if it's installed on a Franklin...and even then the caution range is different than what you say is placarded.

OK - many thanks

Kyle, if you don't have it already, the TCDS is available for download in the members section (of the website - not the forum). The RPM restrictions are contained within the document. It's also available from faa.gov.
