Great as usual!

The old Brackett Air Filter was extremely dirty and I could not get the gooey, sticky, varnish material off (used solvents, WD40, and Gunk) the housing to inspect for serviceability during the annual. So I purchased a new Brackett frame housing and filter. I tired another product from Aircraft Spruce call StrutWipe I use to clean the chrome strut surface. StrutWipe got the varnish off the frame and cleaned up the intake with no issue. It worked extremely well in cleaning up all dirty sticky areas. I was able to inspect for cracks in the frame and found the housing in great condition. I was able the return the new Brackett housing to Spruce with no issues and ordered just the filter. Both Brackett and StrutWipe are great products, worth every cent. Excellent service from Aircraft Spruce as always!

Everything we received in the order was on time and in perfect shape. Could have been better, except for you now having to charge New York State sales tax. Bummer.

Q: What is the difference between Brackett BA5110 and BA5110A?

Per the supplier: The BA-5110A has airlocks for mounting and they are STC'd for different aircraft than the BA-5110.

Q: How can I obtain the foam gasket seal which goes in between the filter housing and the carb heat box? A new assembly comes with one but don't see the gasket seals listed as replacement parts. Specifically, I'm looking for the gasket seal for Model BA-4106, Rev. D.

Yes, you can order just the gasket. Search part number BA4101 (BRACKETT AERO 4101 GASKET FOR BA-4106) on our website to order.

Q: Does the filter assembly produce type come with a filter element or will that have to be ordered separately?

The assembly will have an element included.

Q: Do you have the BA235E?

Yes, BA253E is our part number 08-14690. You can type 08-14690 directly into the search bar to go to the ordering page.
