My friend Longbridge has been working for years—these things always take far longer than you think they will—on a Lancair 320 with a lot of airframe mods, the most conspicuous of which are a double-slotted Fowler flap, enlarged empennage surfaces, and leading-edge cuffs on the outer panels of the wings. And then there are the powerplant things—some engine and cooling mods, electronic ignition and so on.
Maiden Flights in Homebuilt Aircraft
Key Takeaways:
- First flights of amateur-built or heavily modified aircraft carry a disproportionately high risk of accidents, frequently caused by builder errors, powerplant issues, or pilot mistakes.
- The author's friend, an experienced builder, hired another pilot for the initial flight of his extensively modified Lancair 320 due to his own lack of recent flight time and unfamiliarity with the aircraft type.
- Key strategies to mitigate first-flight risks include meticulous multi-person preflight inspections, thorough ground runs to check for powerplant issues, and cautious initial runway hops on long runways.
- It is also advised to avoid inviting an audience to reduce pressure and leverage the FAA's rule allowing a second, more competent pilot during the testing phase.
