Niko182 Posted November 30, 2022 Report Share Posted November 30, 2022 I dont know the answer, but i can narrow it down. It was pre 1999. Quote Link to comment Share on other sites More sharing options...

He's asking when the M20M went from vacuum speed brakes to electric. Quote Link to comment Share on other sites More sharing options...

Still educating myself. Thanks, In 1989 when the M20M (TLS) was introduced it had vacuum speed brakes. I owned serial number 27-0007 which had vacuum brakes, which were called Descent Control Devices. The 1993 TLS, serial number 27-0150 that I owned had electric speed brakes, so somewhere in between 1989 and 1993 they switched from vacuum to electric. If I remember correctly though it was just the 1989 models that had vacuum speed brakes. Someone with a 1990 model will chime in I'm sure. 1 Quote Link to comment Share on other sites More sharing options...

kortopates Posted December 2, 2022 Report Share Posted December 2, 2022 i am pretty sure a quick call to Precise will tell you when they introduced electric. that will narrow it down.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Fly Boomer Posted December 2, 2022 Report Share Posted December 2, 2022 It’s been a couple of days since I read this topic from the beginning, but I can say that a 1989 M20K has vacuum speed brakes. Quote Link to comment Share on other sites More sharing options...
Marc_B Posted December 2, 2022 Report Share Posted December 2, 2022 I don't have the answer but I DO have the Precise Flight 100 series (original electric speed brakes). Here is the STC that at least shows when they were approved. Looks like late 1988, but I'm not sure what the 1991 revision was regarding.
