Engine Break-In

[bryancobb]

Hey Richard,

I did the Maintenance Test Flight on my ship yesterday. The GEM-602
Engine Monitor is GREAT!!!!

It flew great.

I don't really know the best way to get the rings to seat. Unlike an airplane, you can't fly around at 100% power for very long.

I'm thinking that in order to break it in so it will be an "oil-mizer" for years to come, I might need to load it up to gross weight and only hover for 4 or 5 hours . What do you think?

Jason in Alaska, If you are listening...... how did y'all do it on new ships at the factory?

Hey Bryan,

Our acceptance flights did not incorporate any break-in procedures for the engines unless you count checking the oil screeen and changing the oil. However, did a top-end on a Safari and did what you are suggesting. Got it as close to max gross weight as possible and then played hovering games for two bags of gas.

By the way, my unit got deployed to Iraq last January and we are hoping to get back by Thanksgiving. I hate the desert but there's lots of flying going on. Let me know if you would like some pics.

Hey Jason!

Thanks for answering with your expertise.

Send the pics to bryan@llind.com
We have high-speed at work.

PS By the way... what were those "rules-of-thumb" on proper rigging of the tail rotor? I remember when you were at my house a few years ago you had told me to reduce hovering RPM to a certain point and look for the point where you run out of left pedal or something like that.
