Default ECI heads/cylinders AD

Just curious.... anyone still running ECI cylinders/heads that are subject to the AD...? And require the 50-hour compression check? Hour many hours??

Thumbs up Thanks for sharing...

Cool..

Okay follow up questions - Do you find yourself doing anything a little more cautiously? Making sure you don't shock cool? Make sure you've get the CHT's in the "green" before take off??

Also, from what I understand the failure mechanism (if there is one) isn't necessarily catastrophic engine failure but, separation of the head from the cylinder and subsequent partial loss of power. Right?

As you could likely guess, I have purchase a 9a with the ECI Group B cylinders/heads. < Correction - I have Group A >

Thanks for sharing your info...

Best cylinders I ever took off a plane. Wish I had kept them, but resale and all that. New ones burn more oil and have lower compression. Go figure.

My eci cylinders were a constant pain. I replace rings three times in 950 hours. The rings would delaminates and eventually I had to rebuild the whole engine due to the ring metal in the system. New lycoming jugs were installed and all is well.

No. I make sure my oil is at or above 100F before takeoff but dont worry about shock cooling any more than I worry about shock heating. I havent heard of any data suggesting that failure rates are any higher on Group A cylinders than non-AD cylinders. I do look over the engine every time the cowl is off, but I would do that anyway.

I installed a new set of ECI cylinders with 10:1 pistons 4 years ago. I have a few hundred hours on them, run them hard, dual EI's, cold air induction, no problems. Injected 360 parallel valve. Rumor has it that shock cooling is a myth. Consider what happens when you fly in the rain, instant cooling with no damage.

Yeah, I've thought the same thing... although it still makes me think twice when it's super cold outside and I'm up high and I just chop and drop...

My comment in post 2 was for group A cylinders. As I understand it group B cylinders must be replaced.
