receptor

[Ron Coleman]

I want to convert my A 65 air filter back to the original filter from the brackett air filter. The brackett filter has cost over over $100. to replace filters since I've started using them. The filters have a 2 year shelf life (stupid) and the airplane becomes not airworthy if the filter is out of date. With the old filter I just have to clean and oil it. True, it does leave oil in the cowling.

My problem is that I have to replace the receptors on the air box. The receptors were removed in order to mount the brackett. I need to identify the original receptors so that I can replace them. Does anyone know which the type, name or part number of the receptor? I hope that they are available from Aircraft Spruce or the like.

Re: receptor

I believe they are "Airloc" receptacles.

If no other replies I'll check my C-150 manual as I think they are the same.

Re: receptor

Try either Mil-spec products or Gen aircraft hardware, they both should stock them and they are airloc fasteners. Also Dan at reeve air motive I think has them in stock. Tim

Re: receptor

So why is it unairworthy after two years? Who says?

Re: receptor

The filters go bad after two years? Caaamon! I know people who would scrape the date off and fly onward! 100.00? Get Serious! Sell your T-Craft and buy a 195 Cessna or a Stearman! Get to know what maintenence money is all about! I ran brackett filters in two cessna 140's, liked em! Even with100 av gas prices as they are, T-crafts are cheap to fly!JC

I replace my Brakett filter at every annual for $8. It takes all of 2 minutes. I am happy with that.

Re: receptor

Wait til you get a real backfire and your cleanable filter caches on fire and you have to replace it. Bet it is a lot more than the 8 bucks.

By the way. I ordered a hot rod filter from Edelbrock for my Camaro. It is the same material and thickness as the bracket filter and just a little bigger. They rate it at 1000 cu.ft./minute. Suspect that means the bracket breathes pretty good itself.

Re: receptor

I guess I have been lucky. I have had my plane almost ten years and no back fires so far. I guess I will have to deal with the mess it causes when it happens. Besides replacing the filter, what else does it do?

Re: receptor

Something i always wandered about, is how does a fabric pleated air filter on an airplane let enough air into the engine when flying in a pouring down rain? I know they do, but i wander how? Marv

Re: receptor

The Brackett STC requires a new filter every year.

After about two years out of the package the foam starts to deteriorate/crumble.
I don't know about the shelf life in the plastic wrapper.

Re: receptor

If the engine backfires in the carb, you are required to replace the brackett foam filter. The backside of the foam may catch fire and burn into a black crud which may go through the carb.

None of that bothers me. The big deal is that the plane is not airworthy until the filter is replaced. If you don't have a filter on hand you don't fly the plane until you can find one ( good luck over a week end or holliday).

I'm going back to the original filter.

Re: receptor

The brackett filters are only about $4-6 bucks each and take about 5 minutes to change. I always keep a couple of spares on the shelf. Store them in a shaded place out of sunlight and they'll last forever in the plastic. If you don't have to use one between annuals then just use your spare during annual and order a new spare.

Re: receptor

Any kind of air filter can be damaged by a carb fire/backfire. I am not sure why one brand would have an advantage over another. I had a pretty long lived fire on the T once and finally got it out by starting the plane (now that I had it preheated LOL) and running the power up and sucking the fire in or blowing it out. That actually does work I discovered. Anyway, other than a bit of smudge on the cowl the air filter element was the only thing damaged. It was still intact but "crunchy" I can't imagine that a one pop backfire with no sustained fire would damage it at all. So pulling it out and taking a look would probably be all that is required. The Brackett filters are relatively inexpensive and do a good job filtering so I would never want to go back...

Re: receptor

Special thanks to Magman and astjp2 for the clews to finding the receptors that I need for my heat box and airfilter.
I know! I know! I'm probably wrong but here is what I found. The 1/4 turn twist lock receptors used on the airbox on some BC12 D Taylorcraft A-65 continental engines are "solid A-LOCK " receptacles. I have been told by several suppliers that the original receptors are not generally available. The originals were without rivet holes because they were ment to be welded in place. Aircraft Spruce has two rivet in types available that should fit. They are the Series #2 part # 04-00948 and part # 04-00951. (Almost $5.00 each).
The question is "why would I pay $20.00 plus shipping for parts to return to the original air filter?" The answer is "because I want to".

Although I hae enjoyed flying my minimax and carlson sparrow, I long to be aloft in a real airplane, my Taylorcraft... soon perhaps.
