Location: Dayton, OH
Accident Number: GAA20CA017
Date & Time: 10/10/2019, 1600 EDT
Registration: N8078X
Aircraft: Piper PA28
Aircraft Damage: Substantial
Defining Event: Fuel starvation
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Instructional

According to the instrument rated private pilot, she was working toward a commercial certificate, conducting an instrument cross-country flight in VFR conditions with a safety pilot. During the final approach the airplane's altitude was low and she added power by moving the throttle but "nothing happened."

The safety pilot in the right seat took the controls and made a forced landing on a highway. During the landing the airplane struck a vehicle.

The private pilot and the safety pilot reported that they were not sure why the engine lost power.

The private pilot reported that the accident flight was the second and return leg of the IFR cross-country flight.

Additionally, the private pilot reported that the airplane had been "topped off" prior to the flight, which was about 181 nautical miles to their destination. During preflight for the return leg, she affirmed that she visually checked the fuel quantity in each tank and, "it was at the tabs". She completed a fuel sample and they departed for the return flight.

According to the FAA Inspector that performed the post-accident airplane examination, during the examination, he observed that the fuel tank selector was set to the left tank. The fuel pump and carburetor float bowl had less than an ounce of fuel in each. The left wing tank did not contain any usable fuel and there was no sign of fuel on the ground post impact. The right tank contained about 12 gallons of fuel.

According to the manufacturer's pilot operator handbook, per Chapter 3, the first step of the Engine Power Loss In Flight emergency procedure state:

Fuel Selector…………………switch to tank containing fuel

The airplane sustained substantial damage to the left wing spar.

  1. Running out of gas. How embarrassing. How dangerous and destructive. At least no one got hurt. The airplane sure did.

    1. They did not run out of fuel, just forgot to switch tanks!! Idiotic error.

  2. No use of wood dowel dip check method for determine remaining fuel quantity at lunch stop, cuz "looked like full to tabs". Landed using tank they burned from first, making it the one that would have smallest residual at landing doing their 30 minute swaps.
    From the POH:
    "It is recommended that one tank be used for one hour after takeoff, then the other tank be used for two hours; then return to the first tank, which will have approximately one and one half hours of fuel remaining if the tanks were full at takeoff."

    Landing instructions include electric fuel pump ON. The fuel pressure gauge must have been inoperative, same as the inoperative or malfunctioning tank level gauges:

    "If signs of fuel starvation should occur at any time during flight, fuel exhaustion should be suspected: at which time the fuel selector should be immediately positioned to the other tank and the electric fuel pump switched to the "ON" position."

    Perhaps reading the POH was "TL:DR", as some people now like to say. If properly trained, the 26 year old instructor should have known how and when to read a fuel pressure gauge. The gauge will have very noticeable down and up cycling as the electric pump passes into chugging air. The clearly visible flicking needle on the fuel pressure gauge will show itself for about a full minute before power loss. They both played with the throttle but neither checked for zero fuel pressure on the gauge.

    Crashed on incorrect fuel quantity management. Enough altitude remained to switch tanks and recover from failure to scan panel and spot flicking fuel pressure needle before exhaustion during approach. Even took time to change xponder code but not to check fuel pressure and switch tanks. Scanning gauges is "TL:DR" too?

  3. If your engine just up and quits in the air with little or no warning, first thing to do is to switch tanks, then check that your mags are on .... just sayin'

  4. Injector cycle terminating is on normal finished in 1.5 to 5 milliseconds.best fuel injector cleaner
