Superior Air Parts' Bill Ross has written a great booklet on taking care of aircraft recips. It apparently went like hotcakes at Oshkosh and they've decided to make it available to the general public in .pdf form. Great data from a great builder.

Interesting article. Noticed this quote in there: wink

“Oil analysis should never be used as a snapshot in
determining the internal engine health.”

I was just reading online the other day about the careful and precise operating techniques required on the early Mooney M20K 231 Continental turbo's with the fixed wastegate or whatever. Sheesh !! Lot to stay on top of and that's just for a single. Apparently Mooney improved it all in 1986 and beyond with the 252's LB engine and an automatic wastegate setup, as well as numerous other improvements both engine and airframe.

And then there's this, gleaned from the interwebs ...

---------------------

DEDICATED TO ALL THOSE WHO WORKED ON OR FLEW BEHIND ROUND ENGINES

We gotta get rid of those turbines, they're ruining aviation and our
hearing.

A turbine is too simple minded, it has no mystery. The air travels
through it in a straight line and doesn't pick up any of the pungent
fragrance of engine oil or pilot sweat.

Anybody can start a turbine. You just need to move a switch from "OFF"
to "START" and then remember to move it back to "ON" after a while. My
PC is harder to start.

Cranking a round engine requires skill, finesse and style. You have to
seduce it into starting. It's like waking up a mistress. On
some planes, the pilots aren't even allowed to do it.

Turbines start by whining for a while, then give a ladylike poof and
start whining a little louder.

Round engines give a satisfying rattle-rattle, click-click, BANG, more
rattles, another BANG, a big macho [censored] or two, more clicks, a lot more
smoke and finally a serious low pitched roar. We like that. Remember
Jimmy Stewart nursing that engine to life in "Flight Of The Phoenix "?
It's a GUY thing.

When you start a round engine, your mind is engaged and you can
concentrate on the flight ahead. Starting a turbine is like flicking
on a ceiling fan. Useful, but hardly exciting.

When you have started his round engine successfully your Crew Chief
looks up at you like he'd let you kiss his girl, too!

Turbines don't break or catch fire often enough, which leads to aircrew
boredom, complacency and inattention. A round engine at speed looks
and sounds like it's going to blow any minute. This helps concentrate
the mind!

Turbines don't have enough control levers or gauges to keep a pilot's
attention. There's nothing to fiddle with during long flights.

Turbines smell like a Boy Scout camp full of Coleman Lamps.

Round engines smell like God intended machines to smell.

I thought I would add this link to FAA powerplant manuals (and other manuals). They have updated the maintenance manuals over the past few years and I, at least, think they are well done (ooo, looky at all the colors..). At any rate some of this kind of knowledge might be helpful in assisted annuals so we could save some bux. Some of it is basic but I hope it will be helpful.

https://www.faa.gov/regulations_policies/handbooks_manuals/aircraft/

There are two powerplant volumes. Happy Sunday everyone!

Twenty eight cylinders with a right hand twist arrangement, 56 spark plugs,seven double magnetos, high and low tension ignition wiring, that monster had it all. Seeing a cut away 4360 in motion was better than sliced bread and,you know what else. When I was coming up on my P oral and practical, I dreamed that I was ask to set up the timing on one. In reality and looking back many,many years,the FAA examiners around Tulsa gave very easy practicals because they knew students from Spartan didn't know squat about squat, knew the FAA requirements for aviation schools called for a high percentage of students passing the A&P tests, and knew that nobody cared anyway. I really thought I was in king cotton when I decided to enroll at Spartan. Going to be waist deep in airplanes. Only thing that was waist deep was airplane junk. That "train on live equipment" junk had been dead for twenty five years when I got there.No component worked on was complete. There were ALWAYS parts missing. And no one cared. And, surprise of surprise, airplanes weren't the main focus. $$ reigned supreme. And sometime later, Spartan figured out that if they started calling the school a college, even more $$ would roll in. College my hind side. None of the courses at Spartan College of Aeronautics and Technology are accepted by a degree granting institution. Nothing but a black hole money scam. liar

Wow, just the opposite of my Embry Riddle experience.

You made a good choice Cujet. Forty some years ago it was harder to sort out the good from the not so good to Spartan. And I visited Tulsa twice. The airlines had been using gas turbine powered aircraft for over a decade and Spartan had one beat up vintage gas turbine laying on the floor. There was no gas turbine training period. The highlight of fourteen months there was leaving the classroom one spring morning to watch AAL land their first 747. No comparison between Spartan and Embry Riddle.

I'm more than a little anal when it comes to Spartan. It was more than a bitter disappointment. Spartan wasn't really about airplanes at all.We moved through the various phases of the airframe and powerplant curriculum, but there was no cohesiveness about it. It was just one big joke. My wife worked as a nurse to put me through the school, and when I finished, I was so depressed about the experience that I became very depressed and she divorced me. I didn't really blame her. She is a very intelligent person and went on to great accomplishments. Me not so much. Several good psychotherapist got me up and functioning again, but I never have been able to completely forget about that year and a half in Tulsa. Still have a tendency to get a little screwy when I hear airplane. Spartan wasn't about airplanes. sick
