Key Takeaways:

Following an engine overhaul, the aircraft initially presented mechanical issues with the nosegear indicator and elevator controls due to improper interior reinstallation.
During the first engine start and taxi, a critical electrical problem arose with excessively high system voltage, requiring the replacement of the overvoltage regulator.
After addressing additional issues like a stiff prop control and missing alternator tubing, the aircraft successfully completed its test flight, though minor tweaks are still needed.

As I related in December 2020’s article, “Engine Break-In,” my Beech Debonair was down for several weeks as the engine went out for an overhaul. I’m happy to report all the big parts are once again flying in close formation, even if I no longer have money to spend on fuel. Almost.

Reacquainting myself with the old girl started with an extensive preflight. As I inspected the cockpit and instrument panel, I noticed the mechanical nosegear position indicator was displaying “UP” when it should have been “DOWN.” As I walked around wiggling everything and taking the flight controls through their full travel, I noticed the elevators wouldn’t move to the full nose-up position without some extra effort. They also didn’t run into the travel stop as they have since I’ve owned the airplane.
