I am trying to verify if the STC covers the 66 F model. If so, does anyone know of good installation shops in the eastern US region? I'm located in VA. My last emails with Duncan say that only the 'long body' is covered by the STC, and that they are working with BK to get the new STC approved for C through K models. I've asked Duncan for an update, as I'm ready to purchase as soon as the STC is updated. 1

I've emailed Duncan Aviation, who hold the STC, for clarification, as they've repeatedly told me that they had to withdraw the STC for Mooney's earlier than the 'L' model - e.g., only 'Long Body' Mooneys are currently covered. To be clear, I'm REALLY hoping the issue with the brackets have been resolved and the STC is cleared for all models....
ProtoFly Posted Wednesday at 06:51 PM Report Posted Wednesday at 06:51 PM Just to update my own comments: Duncan has confirmed that the STC is still good for all Mooneys, but there's a bit of a catch: One or more of the brackets for the servos will need to be modified, depending on the airframe. SOME A&P/IA's are OK with this, and consider it to be a minor modification, and some may not be OK with this. Updated brackets are in the 'approval' process, so be aware that you may or may not have to get a field approval for the bracket modifications. Thinking it might be time for me to order up an autopilot...would like to get it installed sooner rather than later, as long as I don't have to go the 'field approval' route.... 1
