The Case of the Absent Avgas

Some accidents arrive entirely without warning, and it is hard to know what or whom to blame.

Key Takeaways:

  • A Cessna 182E crashed shortly after takeoff, killing both occupants, due to fuel starvation, an incident the NTSB attributed to "inadequate preflight planning."
  • The article disputes the NTSB's finding, arguing that the pilot's preflight calculations, based on engine monitor data, suggested sufficient fuel for the planned flight.
  • The actual cause of the unexplained fuel shortage remains unclear, highlighting a critical discrepancy between expected and actual fuel levels.
  • The author emphasizes the danger of relying solely on digital fuel monitoring systems and the vital importance of physically verifying fuel quantity before flight, even for short trips.

Some accidents are preceded by warning signs. The takeoff into the teeth of an impending thunderstorm, the pilots smelling of alcohol, the stuffing of the last bag into an airplane already almost tipping over onto its tail—onlookers shake their heads or hold their breath. But some accidents arrive entirely without warning, and it is hard to know what or whom to blame.

A doctor, 67 years old, and a friend flew in a club Cessna 182E Skylane from Clemson, South Carolina, to Orlando, Florida, to pick up a crankshaft. The weather was fine and the flight apparently uneventful. After completing their errand at Orlando Executive, they took off for a 35-mile hop to Massey Ranch in Edgewater, possibly to get fuel there for the return trip. The price of fuel was substantially lower at Massey than at Executive, and they could save a hundred bucks or so.
