Modified Lancair First Flight - Longcut w/ Radio Chatter & Airborne Chase - Ramona Airport

Congratulations to Hakan Langebro on the first flight of his highly modified Lancair Legacy. Hakan is an experienced home builder and engineer who set out to modify the slow flight performance of the high performing Lancair 320. Four years in the making this first flight is a first brush at what should be an exciting project. The flight was cut short due to high engine temperatures, so after some reconfiguring, we hope to be able to finish the first flight card and continue the march towards evaluating the airplane's new features! Thank you for tuning in, we appreciate the support and feedback.

The radio sounded good. During the high-speed taxi the engine was determined to be rich (based on sound, engine smoothness, and indicated FF). The engine was leaned (~2”), found to run smoother there. That mixture setting was used for takeoff. Normal takeoff, normal gear retraction. Nose gear door was found to be open ~1”. One minute after brake release the CHTs were out of limits and increasing. To cool CHTs, the mixture was set to full rich, we accelerated to 130 KIAS, and the power was reduced to 10”/2500 RPM. This reversed the trend on the CHTs. While we waited for CHTs to get back in limits to continue the test card, the oil temp went out of limits and increasing. At this point, the decision was made to RTB. A normal landing was flown flaps up. During the approach the airspeed was checked with chase and found to be 10% off, the Lancair was indicating 110 KIAS but chase showed 100 KIAS.

Once cooling is under control start with “flaps up” handling quality confirmation before flap work. #flighttest #aircraft #aviation #fly #testpilot #lancair #lycoming #flying #aviationphotography #avgeek #pilot #horsepower #engine
