There are NO legal led direct replacement bulbs!

Nope. The incandescent bulbs that have always been in our Mooneys are the same ones at the auto part store. No PMA on them.

The boxes mine come in say TSO.

There is an error in Excel called Circ-redun

"There are a couple of important differences. One difference is that an FAA-PMA part carries a requirement for the PMA holder to document to the FAA where this part can be used on the aircraft, engine, or propeller. The PMA holder must also include this information on the PMA supplement letter and parts packaging. This information is referred to as the part’s “eligibility.”

With a TSO part, the installer makes the decision on where the part is used. Another thing that is different between a PMA part and a TSO part is the nature of their approval. A PMA holder must demonstrate to the FAA that the part that is being produced is equal to or better than the original (OEM) part it replaces. In contrast, a TSO-produced part must only meet minimum prescribed FAA-mandated standards or requirements."

As a owner as the logic follows from the first post we must make sure there is FAA data before installing something on our certified plane.  No data no can be installed.  We are finding out that the tungsten bulbs have no FAA data

Much more apropos!

These PSA paddle bulbs are something I haven't seen before. Like the old bass sitting amongst the weeds and a shiny spinner bait trolls by, I'm interested.

I want wireless tire pressure monitoring.  Garmin has it.  I wonder how illegal that would be.

I can't imagine anyone would give you grief for using these. It says that they only work on metal stems. Our tubes have rubber stems. They are probably using the stem as part of the antenna system. I believe these work on the LF RFID frequency.

Lots of Cirrus owners tried them, and took them off. They don't work reliably, and worse, have been known to deflate the tire.

Get the airstop tubes. Seriously minimizes the number of times you will check the air pressure.  and they are FAA compliant and last a long time.

How can a valve cap deflate a tire?

The valve cap cannot read tire pressure unless it has access to the air inside the tire. It does this by depressing the schrader valve in the valve stem. Then, the Chinese rubber seal in the transmitter leaks, and voila, you have a nice flat upon landing that ruins your fairing, tire, and wheel, and wallet.

Yea, I figured that out right after I wrote that post. I wouldn't use them.

i have used the preflight, look at tire method for 35 years. It seems to work fine.

I can second this. They really work.
