Screaming eagle STC

[Supereri73]

Is this STC still available anywhere? Is a 244hp M20S still able to be upgraded to 310hp with a gross weight increase?

Mooney owns the 310hp stc, so yes you can get it at an msc.  There’s apparently some debate about the gross weight increase.  See the classifieds section on the eagle that was recently for sale for info.

The STC is clear - it says that any R or S with the STC must be operated in accordance with the AFMS.  The AFMS clearly states that MGW is 3,368 Lbs.
