Today was the long awaited first break-in flight of the newly overhauled O-470. We had attempted to get a flight in yesterday, but during the run-up there was an issue with the prop control so we had to taxi back and call it a day. With the prop control fixed we taxied out and made a request to the tower to circle over the airport at 1500'. The tower approved the request, and we climbed to 1500' and entered the pattern. The break-in instructions say to fly at 75% power for one hour, so once at altitude, the power was set at 23"/2450 and we went around an around and around, overall 25 laps.
At the end of the first hour, we landed and returned to the shop for another inspection to make sure that things were ok with the engine and to verify that there were no leaks. After getting the ok, we departed again for another hour in the air and after the hour stopped at KBVS to get something to eat. After lunch, repeated the same thing and put another hour on the engine before returning to KRNT.
Next up will be an oil change/inspection and then we'll be good to go for another 12 hours until the next oil change.
