What year did Mooney start using electric speedbrakes on Bravo's

What year did Mooney switch from vacuum driven to using electric speedbrakes on Bravo's. Still educating myself.

 

Thanks,

I dont know the answer, but i can narrow it down. It was pre 1999.

The Ovations started with electric brakes in 1994…

If that helps any….

Hmm, 252 came with them from the beginning, so 1986

In 1986 the 252 speed brakes were vacuum. He's asking when the M20M went from vacuum speed brakes to electric.

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.

Yeah, just noticed he asked about electric.  Reading before coffee.

i am pretty sure a quick call to Precise will tell you when they introduced electric. that will narrow it down.

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.

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.

My Bravo, Serial number 27-0106, a 1991 model, has electric speedbrakes.
