Investigation Docket - National Transportation Safety Board:


Location: SHELBY, NC 
Accident Number: ERA20CA226
Date & Time: 06/22/2020, 1240 EDT
Registration: N1718Q
Aircraft: Cessna 150
Aircraft Damage: Substantial
Defining Event: Fuel exhaustion
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal 

Analysis

According to the pilot, he completed a preflight inspection of the airplane he had recently purchased and departed with full fuel tanks. During the flight, while receiving flight following services from air traffic control, he was requested to adjust his heading and was eventually routed back on course. When the airplane was about 3 miles from the destination airport, the engine "sputter[ed]." The pilot verified that the fuel shutoff was on, primed the engine, and pumped the throttle with little improvement from the engine. He noted that when the airplane was pitched down, the engine would "sputter," and when it was pitched up, the engine would run. He checked the fuel quantity, and the left fuel gauge indicated 1/8 usable fuel and the right tank indicated "almost" 1/4 usable fuel. The pilot decided the airplane would not be able to make the airport and located a field to perform a forced landing. During the accident sequence, the airplane experienced a hard landing and the engine mount and left wing were substantially damaged. After the airplane was recovered, the pilot drained the unbreached fuel tanks and 3 gallons were removed from the airplane. According to the airplane Pilot Operating Handbook, the airplane held 26 total gallons of fuel, of which 22.5 gallons were useable. The pilot reported that there were no mechanical anomalies with the airplane that would have precluded normal operation prior to the accident, however, the right fuel gauge was slightly incorrect.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's inadequate preflight and inflight fuel planning, which resulted in fuel exhaustion.

  1. Yet another example on KR where you don't just trust your fuel gauges. You are supposed to keep up with your gallons per hour fuel burn for your conditions. He failed to do one of the basics that student pilots learn early on.

  2. Surprisingly the most useless gauge in a GA plane is the fuel gauge.

    1. Actually it is not that surprising. Unlike science like say air pressure for the airspeed indicator and altimeter or a gyroscope for the attitude indicator, simple fuel monitoring for GA aircraft means old school float valve mechanics which was also used by automobiles which are still not accurate to this day (spring and cable and wire just isn't all that accurate, especially as the metals expand and contract based on temperature).
