The baggage compartment STC used to be held by a company known as O&N Fabrications. They did a lot of work with auxiliary fuel tanks in a lot of models. What they were really known for was taking a P210 airframe and mating it up with a turbine. It was called the Silver Eagle. Anyway... O&N went out of business a few years ago and Griggs Aircraft Refinishing bought them out. Yes... the same folks that painted Woodstock. Anyway... they bought out all of the STCs that O&N held and are still currently selling them.

(Figuli is the Man!)

If anyone is interested I have a extra pair of cessna 150 long range tanks. (Moat)

There are only a few special additional parts that are needed to install these in stock wings.

Mainly the Flap Bell crank supports (2 right and 2 left). I do have a extra pair of new old stock right flap bell crank supports and have located the extra pair of left at a suppler.

The other parts (L section, hat sections (from a 170 wing), tank covers (had the originals Digitized and can be laser cut from 2024T3 .040,) can be fabricated to make standard wings to stock patrol wings.. With some work..

You end up with stock long range tank wings that can be installed with only a 337.

No STC needed and the fuel is not in the cockpit.

PM me if you have interest in the extra pair of LR tanks.

Michael I just sent you a PM.

Do you know if the stock patroller wing tanks were an option on the '59 models?? My neighbor has them in his '59 150 but that doesn't necessarily mean its stock...
I would really like to do this conversion for my 150/150. The Del-Air STC is $5000 plus the $$$ for installation. I think converting to stock patroller tanks would be about the same amount of work with much less money for parts.

Well in 1960 was the first year they introduced the patroller with long range tanks.

So your neighbors plane was most likely produced late 1959 or is a 1960 or someone put LRT wings on it.??

Since it is a stock cessna part putting on the wings needs a IA that is comfortable with the installation and will document it in a 337.

Chris at Del Air is not selling the STC since his welder died and yes the parts are expensive and installation is not cheap..

Even with all the parts for a stock set of tanks it will cost and it will cost less than the Del-Air but it still is a good amount of work.

If you can do sheet metal work, Rivet, derivet have the tools and someone that you can work and you do a lot of the work,
it will be easily manageable..

To just farm it out yes it will cost $$$.

Here's what a modified wing for LRT's looks like so you have a point of reference.

It's work for sure but it's pretty basic work. Guys that do sheet metal and structural repair work for a living would find it to be just another day at the office.



Jim

thanks Jim for the pictures.
Had a nice conversation with Michael -
I have decided that to modify my wings is to much of a project for my mechanic and I to take on because of how long the plane would be down.
Michael suggested buying a second set of wings and working on them as time allows and swapping wings when completed which isn't a bad idea but still outside my comfort zone.
Thank you Michael for your time going over all these options with me.
