This is the latest and greatest from Duncan. Looks like it is held up at Bendix.
Hi Scooter
Yeah, this is hard to stomach and I am sad for Mooney operators.... I wish we could get some traction with upper management at the OEM to get this pushed forward...but this is where we are at the moment...
The original STC drawings and installation instructions have been revised by Duncan Aviation Engineering, which was sent off to Bendix King in June of 2025.
BK Engineering has been evaluating the revised Duncan information (for several months now), and once that evaluation is completed, BK Engineering will ask the BK ODA to approve this additional data "as approved supplemental data to use with the original STC".
We are hoping to have the BK ODA approve on this revised data the end of Quarter 4 of 2025, but additional parts have to be designed, manufactured and added to the original STC kits (which won't happen until approximately the end of Quarter 1 of 2026).
Thanks
