Flight Enhancements Electric Step mod

[Keith20EH]

Hi Vintage fans, 

I just removed my vacuum pump, in prep for the Garmin auto pilot.  I installed the Flight Enhancements electric step in place of the vacuum driven servo to raise and lower my step.  The Kit and instructions were very good and complete.  I only had to buy about 10 feet of wire, a switch and a fuse holder for the required 1 amp fuse.  The install went well, slightly more than the estimated 5 hours.  I used the air line as conduit to run the wire from the servo to a separate switch on my panel.  I wanted the step to be operated after start and when taxiing in, not on the beacon or master switch, which is an option.  The hardest part was removing the bracket the Brittain servo mounted to with a cut off wheel.  (Very careful to not grind into anything other than the bracket).  Here are a few picture to any one interested.

Nice job!

BTW, after removing vac pump, filters hoses, regulator, servo, etc and adding electric servo, my empty weight dropped about 5 lbs to 1639.5

Nice work Keith!

Great pirep for Rob’s / flight enhancement’s electric step servo mod.

inviting @takair to cruise by…

The 5Lbs is interesting…

So what are you doing with the old step actuator??

[Keith20EH]

Now the old step servo resides on my shop museum shelf next to the removed gyro instruments, vacuum pump and and other assorted fossils.

Welcome aboard Bri!

See note above for another available step actuator…

Then compare the economics of replacement between the two options…

I've got it too Works great

I'm looking for an AP experienced (even once) with the vacuum, step removal, and the electric step installation somewhere in New England or the Northeast.  Any references? 

This is a great (and timely) pirep!   

The avionics shop that installed our GFC500 and GI275s completed the step wiring from the beacon switch to the tail and removed the vacuum AI from the panel, but the vacuum removal and step installation still need to be completed.  ...so there'll be one more step servo on a hangar museum shelf soon.
