I installed the trimmer fuel mod on a bare fuselage. I would not want to do it with fabric on, but it could be done as previously stated. My plane still feeds more out of the left tank when on both. But all in all, I would do it again. I my memory serves me correctly you can just change the fuel valve under his STC. But I'm not sure.

As far as the Dakota valve STC, the installing IA determines compatability of the STCs.

I am trying to convince my IA of the merits of installing the Dakota valve on a Trimmer fuel system on a Clipper without going down the 337 route.
Could you you guide me to a reference for the above that I could present him with please?

FAA/PMA and STC'd part that replaces the same part number in the PA18, 20 and 22 via an STC. AC 23-27.

Why don’t you want him to do a 337? If it is an STC part, by definition it’s a major alteration.

Re: trimmer fuel valve
As always - thanks Steve.
I don’t want to go down the 337 route as the Jamaica New York FSDO is blanket not processing 337s for N reg aircraft based outside of the USA. Like me. I am trying to find a route around this.
I have heard that FAA Oaklahoma may accept a 337 directly or that any agreeable FSDO may also file for the 337. However I haven’t heard of a friendly or understanding FSDO as yet.

All 337s are sent directly to AFS750 in Oklahoma City when complete. No need to go to the FSDO unless for a field approval, and many FSDOs won’t do them anymore. Next bet is a DAR with field approval authority, or a DER that can approve data for major alterations.

I think you will be happy with the maule valve, the newer valves are nice but the maule valve will give you years a trouble free service. Its a good valve.

My mistake - inaccurate verbage. I meant that I understand Oaklahoma or an agreeable FSDO will process the 337 for a field approval. Regular repair 337 processing is not an issue. I have spoken to a DER based in the UK but he was talking in the region of $5k+ to work on a field approval based on follow on data from a previous approval eg. The Trimmer gear re-enforcing mod.
Sure the Maule valve is great but the satin finish and red handle of the Dakota valve meant one appeared in the post.

Boy if he is charging $5k, I’m really undercharging! I think the most I’ve charged for a DER approval is about $500.
