Well only this morning, in fact on the first flight of the day. I had some excitement. Took off, but the climb rate seemed poor and the engine down on power. I went through everything and spotted the cylinder head temperature gauge was pegged right off the scale. After some excitement and confusion I succeeded in getting rid of some of my 'passengers'  and a hurried descent and landing was made. True to my training I made sure to aim to land deep and carry a bit of speed. If the engine quit on short finals it could go horribly wrong. Better to hit the hedge at the end of the runway at walking speed than crash through wall at the other end at flying speed.

All's well that ends well. It looks like at least one pot is blown. Spoiled the day somewhat. On the other hand I did get the rest of the day off spoiled a little by my wife taking me shopping, unconvinced of the trauma caused by my close shave with death!

Just proving once again that good training is all important. You may only have to use it once in your career but once is enough.

Did you have a failed plug on that cylinder? What were the CHT indications?

Don't know about the plug, as we had no certified mechanic on the field not even suitable tools So we just pushed it into the hangar. Someone will fly in tomorrow and tear it down. CHT just pegged out to end of the gauge, past the red line and past the 300 degree mark. There was an obvious lack of power, no real vibration but a burning smell. It's a six cylinder, fuel injected Lycoming IO-540. Turning over the prop on the ground revealed two soft cylinders, one with virtually no resistance at all. The CHT is only measured off the hottest cylinder so that's the obvious suspect. We'll find out tomorrow no doubt.

Shit. You better remove all the plugs and stick a boroscope down that cylinder. If you were rich of peak and CHT off scale with loss of power, that sounds like a pre-ignition event and you might've melted through the cylinder.

Here's a couple links to seminars for EGT CHT and Engine Management. Best if you review all of them, but I marked out areas within the videos that are relevant to you.

BTW,

With BIG BORE Continentals and Lychos - you MUST have a 6 point engine monitor. You can get a 6 cylinder JPI with fuel flow for under $1500 and 10 hours installed.

Agreed, I suggested it to the boss but put it off as he was thinking about selling it. Bet it's ordered and fitted ASAP now. Thanks for the videos. I've done some reading on the subject before but suddenly it's all the more interesting now!

In a jump airplane you should count yourself lucky to have TOMATO FLAMES and most of the oil that the airplane holds. Well equipped isn't a word I'd use to describe the one I flew. I'm not even sure calling it equipped in the first place is a fair statement.  :lol

Popped into ISP yesterday on the beautiful sunny evening it was expecting a zoo and mad house all in one. Even put a few hundred pounds of extra fuel on because of all the bug smashers about and the likelihood of a go around was increased. Departing home, nobody. The center freqs were quiet. Not one TA much less the usual RA we get dodging VFR airplanes in the area. 2 Cessnas inbound as we landed and that was it. Didn't see anybody on the way out either, got turned on course earlier than I remember being, Long Beach Island was quiet and again landing at home, not a soul in the area. Spooky.

Tomorrow we go to Quonset State for a pickup and ISP again Tuesday. Hoping for 500' overcast.

Glad he is ok....are you sure Corky wasn't piloting? Looks like his handy work.
I was thinking of a certain 80th bomber pillet myself. :D Hope the guy is alright, and ouch. :uhoh

wolf what do you use to capture radio traffic, I film a ton of stuff while back seat drivin but haven't found a way (that I like) to capture radio transmissions yet.
any pointers/suggestions on equipment?

Was teaching Saturday night after a day of paintball, when the ATIS at KBDR comes up with Closed due to emergency. So we had to put down in New Haven. Turns out - a guy I know in a Cherokee 6 got low, slow and behind the power curve - and landed short of the blast fence. Maybe landed is a misnomer - he ripped a wing off, which exploded behind him luckily, plowed his nose through the blast fence - it could've been worse. Suffice to say, the airport was closed for the next 20 hours.

Already back from ISP Wolf.  In and out of Quonset State and White Plains tomorrow racing home to start my vacation so I'm not going to be sticking around much.  If I get up that way for any amount of time or we say overnight I'll look you up.

Relative to my incident, turned out to be a blown compression seal on the piston of number five pot, which just happens to be one with the monitor. The piston is melted. Makes me wonder what would have happened if the same situation occured on a cylinder without a monitor.  :headscratch:

We're going to replace all six cylinders and fit a six point engine monitor. So that's a good result.
