Brief Description: FIRST engine start!!
|
|
I have to say, it was pretty nerve wracking, but all things considered, it went perfectly.
Jim from Premier Aircraft Engines, came to the airplane at Aurora to guide me through the first time start and engine check out. The process went like this:
He looked over the airplane very carefully and the only comment he had was that the Hartzell prop/hub nuts should be safety wired with .041, instead of the .032 I used.
Removed the bottom spark plugs
Disconnected the oil pressure sensing line at the mechanical gauge I have in the panel and put the end of the tubing in a container.
Crank the engine to fill the galleys and until oil came out of the pressure sender hose, then reconnect the hose to the gauge.
Crank the engine again until oil pressure comes up. In my case, it read about 35 psi while cranking.
Put the bottom plugs back in.
Chock the main gear and engage the parking brakes.
Switches off, full throttle, mixture rich, turn on fuel pump until fuel pressure stabilizes, then Mixture arm to full lean/cut off.
Throttle about 1/4 open, turn on Mag switch, start cranking, when it fires, mixture to full rich.
It fired on first blade through and ran a little rough (labored), set throttle about 1100 rpm, then turned on electronic ignition. At that point the engine really smoothed out and ran SWEET!
Verified EIS/EFIS OP agreed with mechanical gauge. Verfied all measured engine parameters responding as expected.
Let it idle for about 10 min at 1000 rpm, the ran up to 1400, then 1700 for about 1 min. Checked RPM drops on single source ignition, then back to idle. At that point, Jim adjusted the idle mixture and idle RPM, which took numerous iterations.
Jim then got into the cockpit with me, went to 1700 RPM and cycled the prop a couple times, it worked perfectly, then ran the prop rpm down enough to be on the governor, to check it stable.
Then prop control to low pitch and run it up to full throttle. BUT... before getting all the way to full throttle, the airplane JUMPED the chocks an
