Now for today’s topics:

Listen to the episode to hear about a couple challenging issues on a Cirrus SR22 aircraft.

First, the TVS’s, or “Transient Voltage Suppressors.”

There are two different types of these TVS’s. One type is installed in the wiring bundle and is hard to see because it’s mostly covered with heat shrink. The other type is a device about 2 1/2 inches square and about 1/2 inch or so thick. The inline type, along with the corresponding fuses, is pictured in the red circle.

These are used to help guard against lightening strike damage. In this particular airplane, the manual indicates there are 10 TVS’s. Each one has its own fuse, and is to be visually checked at the annual inspection.

Here’s a closer view of a couple of the fuses for this system.

The various TVS’s are located in different areas, including some in the center console area, accessible by removing the panel near the copilot’s left leg.

That’s one topic we discuss in this episode (Transient Voltage Suppressors.)

The second topic is seatbelt airbags.

The AmSafe system includes an EMA (electronic module assembly,) one inflator for the pilot seat and one inflator for the copilot seat, inflatable airbags incorporated into the seatbelts, and the wiring to connect all these components, including a test plug.

The test plug is used at the annual inspection. A test box is connected to the test plug, and the tester gives a pass/fail indication of the various parts of the system.

We talk about this system in today’s episode as well.
