Flight Test Interruptus

Gemini Sparkle

Key Takeaways:

  • After an engine overhaul, the author's Beech Debonair revealed several issues during initial checks, including elevator control interference and an incorrect nosegear indicator.
  • Further problems arose during engine start and taxi, with the engine monitor showing dangerously high system voltage, tracing back to the alternator or overvoltage relay.
  • Technicians addressed these mechanical and electrical faults, replacing the voltage regulator and fixing control issues.
  • Following repairs and a successful extended test flight to seat the new engine's rings, the aircraft is now flying again, with minor adjustments still pending.

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.
