Scroll down to see a video about scat hose installation.

Recently, I got an email from Jeremy Zawodny, and he told me a story about his Glastar airplane, which is powered by a Lycoming O-320 engine.  He experienced a partial power loss soon after takeoff, and when he pulled the carb heat, the power was restored.  Listen to today’s episode to hear the rest of the story.

Here are some pictures of Jeremy’s induction airhose:

Well done Jeremy, in replacing that worn hose!  And thanks for letting us share your story!

There was an SAIB (Special Airworthiness Information Bulletin,) that was issued awhile back that talked about air hoses on Piper airplanes.  Here’s a link for that SAIB… it’s worth taking a look at and checking your air hoses, whether you have a Piper, or some other type of aircraft.

It seems there is a mistake in the bulletin about the part number for the air duct they talk about.  Here’s a picture of one part number air duct that is used for some Pipers:

 

Remember, there are 4 different types of air hoses (ducts) that we talked about in this episode:

  1. Scat –  Single layer red/orange color high temp hose with thread on the outside and steel wire on the inside.
  2. Sceet – Same as Scat, except double layer fabric, with the steel wire between the layers.
  3. Cat – Single layer black lower temp hose with thread on the outside and steel wire on the inside.
  4. Ceet – Same as Cat, except double layer fabric, with the steel wire between the layers.

If you own an airplane, go check your air hoses in the engine compartment, and make sure they are in good condition and none are about to collapse.

Finally, here’s a YouTube video I just posted, about how to install the most common type of scat hoses I’ve seen in airplane engine compartments.
