1.5 air time
1.7 flt time

Events:

  1. Engine break-in
  2. Two slow leaning events at 2300 rpm, full throttle. Data review shows that all cylinders reach peak EGT within 0.1 to 0.2 USG/h fuel flow. This is about as perfect as could be hoped for.
  3. Ran left tank dry. The fuel pressure, with boost pump OFF, was 22 psi. As the tank ran dry, the pressure slowly decreased to 15 psi, then the engine began to run rough. The fuel selector was switched to the right tank, and the boost pump was selected ON. The engine recovered almost immediately.

Snags:

  1. RPM was 2660 during the take-off roll, but was lower at max rpm later in the flight, in the range of 2590 to 2610. Oil temperature was 120 deg F and oil pressure was 95 psi during the take-off roll. Later, with oil temperature of 184, and oil pressure of 82, the max rpm was 2610.
  2. EIS 4000 warning light was not working at the start of the flight, but started working part way through. Need to confirm connectors on the back of the EIS 4000 are secure. Also should check the connector behind the annunciator light group.
  3. SD-8 Alternator does not seem to be working. Will defer troubleshooting until engine break-in is completed, as it would be useful to check for AC output from alternator during an engine ground run.
  4. EFIS does not power up. It is in a continual reboot cycle at about 1 Hz. Thus no EFIS data is recorded.
  5. Air leaks at canopy bow. Try adding some stick-on foam there.
  6. Loud buzz at high speed from aft part of canopy skirt. Try some stick-on Velcro or felt.
  7. Data system is not recording fuel pressure. Need to confirm whether fuel pressure is on Aux 2 or Aux 3. Both have been enabled for now.
  8. Turn needle in turn and bank not working. The OFF flag is removed when power is applied, so power is getting to the instrument.
