252/Encore conversion STC

[gyrene]

There is a lot of conversation about the 252/Encore conversion but no mention of an STC. I am having my -MB overhauled next month (Western Skyways) and am considering the engine conversion. The folks at Western Skyways say the conversion is simple and straightforward but since they are doing the install they are looking for the STC. Any information/insight would be most helpful.

PM Parker or call Don Maxwell's shop who performed the conversion for Parker a few years ago.

There is no STC for the conversion. An STC would be required if it was a mod done by other than the Mooney Factory. This is a retrofit to the existing TCDS and authorization comes from 2 Mooney drawings - one for the brakes and one for the engine. You have todo the brakes first or with the engine - can operate it with just the engine. If you weren't already planning on doing this before the engine I am afraid you are in for a bit of a shock at the cost to buy all new Mooney parts for the brake mod. See my other post/thread on the details using the search function. It explains the mods. The engine is the easy part.

Yep. The brakes and the gear doors are the expensive part. Also you'll need new flight control counterweights.

your engine will become a TSIO-360-MB/SB

Best to handle this at a Mooney Service Center. 

Some of the brake parts were available from Aircraft Spruce for cheaper than Mooney list price.
