It’s been a challenging week of airplane maintenance for me.

Here is a sampling of some things I’ve been working on at Classic Aviation:

  • A Beechcraft P-Baron with three issues:
    • Right engine #6 CHT indicates too high in the climb.
    • Right fuel selector valve handle very stiff to turn.
    • Cockpit door warning light comes on when aircraft is pressurized.
  • A Cessna 414 that’s in for annual inspection.
    • A total of five engine cylinders that need to be replaced due to the ECI cylinder AD.
    • A panel lighting issue .
  • A Piper Apache with a hydraulic system problem.
