Key Takeaways:

After an engine overhaul, the author's Beech Debonair initially exhibited issues with the nosegear indicator and elevator controls, which were promptly fixed by technicians.
During the first engine start post-overhaul, an overvoltage condition was detected, necessitating the installation of a new voltage regulator.
Further test flights led to additional minor adjustments, including a stiff prop control and missing alternator ducting, before the aircraft was deemed ready for flying.

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.
