Thanks for doing this, I love to see a new resource for our Skymasters! That said, will this be legal to install on a Part 135 operated 337?

When I get the PMA approval it will be. I should be sending the data package to FAA engineering this week, then itís wait time and back and forth with them.

I am having 100 units made and I do expect my first five evaluation units in about 14 days. The balance of 95 units will follow.

Pricing will be in the 250-300 dollar range. Those that want to do the owner produced part scenario can get them rather quickly.

Dan,

I am definitely interested ASAP. Please let me know when you have them available and what you need from me.

Thanks,

Tripp

First 5 units scheduled for delivery Dec 18. Units will be universal for P models and unpressurized models. The two .070 holes for the pitot head are in different positions between the pressurized and unpressurized models.

Confusing statement - "Units will be universal for P models and unpressurized models"

but then you say - "The two .070 holes for the pitot head are in different positions between the pressurized and unpressurized models."

So which is it? Are they universal, or will you be producing two versions?

What I am trying to say is the heater is universal for both versions. The heater will have two sets of holes (.070) one set is used for P models, and the other set used for un-pressurized.

The holes for a pressurized aircraft are .050 from the center line of the part, .600 inches apart.

The un-pressurized aircraft has the top hole .100 from the center line (yes the front hole will look like a Mae West), and the lower hole is .150 from the center line, these holes are also .600 apart.

These dimensions are from the SE1230-7 template as described in ME75-6.

Installation will be using two #50 drill bits (supplied) that you will put in your existing holes, peel off the release paper from the back of the heater and slide down over the the two #50 bits which will align the heater to the aluminum pitot block. One wire from the heater will be RTV'd down the channel on the pitot block to the Thermo Disc temp controller, the other wire will connect to the aircraft blue power wire. Once this is completed you will leave the #50 bits in place, place RTV on the heater unit and install in the strut fairing. When the unit is installed in the strut fairing with the two screws, then the #50 bits will be removed. These instructions are what is described in the maintenance manual, and ME75-6 Replacement Procedure, and Figure 1, Pitot Head Replacement 337, F337, T337G, FT337G

So the long and the short of it, instead of making two different parts, all four of the .070 holes are incorporated into one part making it a universal fit when installed, RTV will seal the extra set of holes.

Can you post a picture when you have one? A photo always helps.

I'll definitely take one!

Happy to go the "owner produced" route.



Leighton.
