Avionics Cooling Fan

This little puppy seen mounted to the bottom of the pilots side of the floorpan,
helps keep the GPS/Com and Transponder units cooled so they don't have a melt down.

Garmin says you don't have to install one of these but they highly recommend it because keeping the unit cooler adds to it's life. At some $4,200 bucks I wasn't going to balk at the cost and weight of the cooling fan. Iv'e gotta admit I just about gagged when I saw the price of the little blower unit at a modest $185.00 dollars, but what the hell that's chump change compared to having to replace one of the units in the avionics stack. The Bendix King Transponder didn't have an inlet for cooling and it just receives what the GPS/Com unit sheds for cooling but one day I'll make an adapter and run it its own cooling line if I ever see it warrants it.

Homer's in July 2001 was a nice 97 degree average temperature. The temps in the gloss black instrument pod plus the engine running must be somewhere around 140 degrees or more.

We had to drill the rivets back out that hold the pilots side kick plate on to mount this thing. To mount it we used 3/16 aluminum rivets with large diameter thin flat heads so the kick plate wouldn't end up having to much of a bulge in the center of it.
