Flight #12

5/23/16

Great flight today with lots of clouds. Takeoff had few 1600, few 5000, broken 7000.

Times before flight: Engine: 14.7, Total: 17.1

Times after flight: Engine: 16.6, Total: 19.0

Flight Time: 1.9

Flew mostly 2500 and 2600 RPM. Flight data card was missing (not installed prior to flight) so no data for this flight.

Flew some slow flight with 1/3, 2/3, and full flaps with turns left and right.

Flew 90% of the time full rich, tried leaning out once during flight. Leaning from 14.7 to 12.1 GPH caused EGT rise from 1290 into the 1400’s, and caused CHT to go from 360 to 400. I didn’t try any leaner or LOP.

Added 100 Low Lead markings over the vinyl near the fuel caps.

Pre-flight #12

5/23/16

Checked the tire pressure: L: 35, R:35, Filled F to 38

Inspected and took pictures of the inboard aileron brackets from inside the wing. Removed outer access panels, inserted a flashlight, and used the iPhone to take pictures. Inspected in accordance with the service bulletin. No cracks found.

Found missing left wingtip lens screw (bottom side). Replaced screw with new.

Flight #11

5/20/16

Post Flight Times: Engine: 14.7, Total: 17.1

Flight Time: 2.7

Oil Measured 6.75 (HOT) after the flight, but measured 6.0 (COLD) before flight #12.

This flight consisted almost entirely of climb performance testing.

First series of tests were done 2400 RPM and 2nd series of tests were done 2500 RPM.

Climbs were from approximately 2000 to 6500. Stable data was 2500 to 6500.

For each climb test used the trim to set the airspeed. All data was recorded and later entered into a spreadsheet.

It was evident that there was better performance in the climb at lower altitudes in the beginning of the climb. IAS was taken as an eyeball average of the data mid climb around 4000 feet.

Need to find and record OAT here.
