I would like to see the data for when the engineers tested the engines to failures. that graph would be the most useful and accurate. The larger number of engines tested the better the data. Great video and love all your videos.
I have a question regarding your comment about never starting an engine unless you need to- Earlier on, you say that an engine not being flown is just as hard on it as anything. At what point would running an engine just to keep it moving periodically offer returns in terms of longevity? In other words, If I have a plane that I know isn’t being flown, would it be better to run that engine every couple weeks for a little bit, to keep things lubricated and moving? If so, how long between runnings would it be before it is worthwhile? Every couple weeks? More frequent? Less frequent? Thank you for your presentation. I find it very insightful.
No, just running an engine on the ground for 15 minutes is worse than just letting it sit. The plane needs to be flown at normal power, and get up to full operating temperature. If the airplane is unairworthy for an extended period of time, then you need to preserve the engine with the manufacturers procedure.
Cold starts do make me cringe, more so with aircraft than other engines. I was a flight instructor and mechanic at a local flight school...winter days= several cold starts per day. (Hmmm, did they get 1500 hrs per day of wear?) The o320's, 360's, and 235's held up very well. They were run hard, I'm sure a fair bit of cruising at near 100% power. Many were well past tbo.
Are there links to this particular Tanis finding? We addressed this specifically with Tanis and theirrecommendation was to leave it plugged in. The cited the example of one of their test aircraft that they left plugged in all the time and it went up to a month between flights in the colder, bad weather months here in Minnesota. They said when they finally tore it down at around 3000 hrs. (if I recall correctly), they said it came apart easily with no signs of rust anywhere in the engine. So I'm confused by the conflicting advice. We fly our Cherokee 2-3 times a week and choose to leave it plugged in so it is guaranteed to be warm when needed.
Here’s a question, I’m a student pilot owner whose having difficulty with both my medical certificate and scheduling with a flight instructor to fly. It’s been over a month since my last lesson, and it appears it’ll be mid January before I can schedule my next lesson. My aircraft is in the Mojave desert, and is an O-320 Lycoming powered Piper Tri-Pacer. I wish I could just take it up, but that’s not an option due to delays in getting my medical. Other than flying is there any non-pickling options to minimize wear and corrosion in the engine?
Alana, Hi... I live in Rosamond. My plane is hangered, and your tri pacer should be too. Here in the high desert you don't have to worry about rust, but possibly dirt or dust because of the winds. I would say work hard and get signed off for solo, then you can fly at your convenience. Sorry to hear about your medical problems, I hope that gets straightened out soon. In the mean time, don't turn the prop over " to circulate the oil" or do ground runups. Pickling is not necessary, but do go and "visit" your plane often and talk to it nicely....Best of luck, and maybe see you at Mojave for Kathy Hansen's flying next weekend. All the Best, Ron
Hello, I've listened to you guys for years now. Do you guys have a podcast so I can listen to the media without having to have my phone screen on? Thanks!
I am looking at a 59 Piper Commanche 180 that has sat in its hanger for 9 years without ever being started. It is located near Calgary Alberta. Somewhat of a dryish climate. Is this a walkaway aircraft ?
Get a pre-buy inspection and find out. Likely, any of the rubber hoses etc will need replacing, but a detailed inspection will tell you most if not all of what you need to know.

The main takeaways I've gotten from this are:
-Fly often
-Fly Rotax
Flame on, my dudes.
Excellent video. Thanks for sharing!

"Throw a hundred dollar bill out each side" I laughed pretty hard at that one :)

Alana, I am a student pilot owner as well. It has turned out to be such a headache!!

Can this be applied to Turbine engines ?

why disuse is harmful for engines? A engine is protected by something when it is running?
When it is running regularly, oil helps to seal and protect the engine componenets
@@DeadstickAdventures Hope there is an auto program, which runs the engine 1hour if there have been 1 week of disuse.
