It's been a while since I had much to report on the Apache so now that we are making headway I'm probably overdoing it... but I like to see the progress!

This is the "prototype" for the new sub panel. We will eventually replace the "switch breakers" with more typical circuit breakers but for now they are being used as we build the panel. The hardest part will be adding the starter buttons on the far left. After this panel is completed we will make some major changes to add new tach, manifold pressure and Graphic Engine Monitor gauges.

It was a tough month for my mechanic and me schedule wise so virtually nothing got done for a while. However, eventually things calmed down enough to get back on the "upgrades"


The engine cover has been finished and looks great. Of course as soon as the nacelle goes on you won't see it!


The interior is torn apart getting everything done.


The new sub panel will allow the pilot to actually see the circuit breakers and switches! In primer as it is being test fit.

Checking the fit of the new top of the "cooling box"


We had a new top made for the box that directs the cooling air over the left engine as the old one was getting too patched to fix.


The sub panel is being test fit. We will make more changes before it is installed but this is close to the final configuration (we think!).

Another case of "while we are in there" as we make improvements to the "cooling box" around the engines on the Apache. We have only worked on the left engine so far but we anticipate more of the same on the right. We are also making a new "sub panel" for the circuit breakers and switches on the left side for the pilot. A lot of switches were simply hidden and out of sight and the old switch breakers were not a good choice anyway.

Left engine has all CHT and EGT wires installed for new Insight G2 installation.

After a long "dry spell" we are making good progress on the Apache again. The wiring for the left engine is complete for the EGT and CHT wiring. We will still have to add the Carb Temp probe and Fuel Flow installation to the engine but this is a good place to celebrate! We are going to do some rebuild work on the engine cooling box that Piper used for baffles. Several of the sides of the baffle box are cracked too badly to fix so they will be replaced. A few other spots will be patched and reinforced.

I am pretty pleased so far with the installation as everything has been included. The Insight G2 seems to be a very good deal for the money as they include all the needed parts for installation.

Copper starter wire was the trigger for this whole upgrade! Left starter wire going in.


Digital gauges means lots of wires!


No project can be run without the proper fuel... in this case Dunkin coffee!


The Apache sign was a fun gift for Christmas from my family!

Unfortunately we had to take a huge amount of time "off" due to life events intervening. However, the work on the Apache has begun again and we got a good start today. The left starter cable has been pulled and is connected to the starter. We are working on the other wiring harnesses to install the new manifold pressure gauges, tachometers, GEM and more. The Apache is going digital! The circuit breaker panel / starter panel is being redesigned. We will install new tracks for the pilots seat. New digital OAT probe for OAT/TAS/Wind readout on the G5. Oh, and shoulder harnesses and new wing/nacelle fairings. We figure that should keep us busy for a while!

Upgrading the Apache means buying more "stuff". Seat tracks aren't very sexy but something you really need to work properly. So new(er) tracks are going in as we do other work. The seats are already out so it's another "while we are in there" upgrade. I got these from John Talmage of Diamondaire and he did a nice job of refurbishing them.
