Fuel Selector Confusion on Climb
A Piper Cherokee 180's LEFT/RIGHT fuel selector is not a BOTH position — engine starvation on initial climb and the decision to land or ditch
The scenario
Departing Venice Municipal Airport (KVNC), Venice, FL — Runway 04, climbing out on a 045° heading. Elevation 18 ft MSL. It is a clear, calm morning: OAT 22°C, altimeter 30.01, light and variable winds. Visibility 10 SM. A textbook VFR day for a local flight or a short cross-country.
You are a Private pilot with roughly 180 hours total time, current and proficient. You have flown Piper Cherokees before, but not extensively. This is your second flight in the PA-28-180; the first was a dual checkout with an instructor two weeks ago. You are flying solo today — a local flight to a nearby airport and back.
Aircraft: Piper PA-28-180, solo, full fuel in both tanks (each tank holds 25 USG; you topped them off before the flight). The airplane is within limits. The fuel selector is a LEFT / RIGHT valve — there is no BOTH position. You must actively switch tanks in flight. The Lycoming O-360-A is carbureted, 180 hp, fixed-pitch prop, fixed gear, steam panel.
Preflight: You checked both fuel tanks visually — they appeared full. You did not dip the tanks with a fuel stick (a common shortcut that misses contamination and actual quantity). You did not review the fuel selector positions in the POH or brief yourself on the switching procedure. You assumed it would be straightforward.
Engine start and run-up: The engine started normally. You ran through the run-up checklist, including a mag check (both mags good), carburetor heat (applied and released, no roughness), and flight controls. You did not explicitly verify the fuel selector position or test the tank-switching procedure. The engine ran smoothly at run-up power.
Takeoff: You line up on Runway 04, advance the throttle, and rotate at 60 KIAS. The engine is running normally. You are climbing at 74 KIAS (Vy, best rate of climb). You are 300 ft AGL, heading 045°, when the engine begins to cough and lose power. The tachometer is unwinding. You have seconds to diagnose and act.

The decision
Before we get into the decision tree — what do you already know about the Piper PA-28-180 fuel system? (Pick all that apply; this records your baseline.)
What the record shows
What the NTSB files show
NTSB DFW05FA028 (2004, fatal): A Piper PA-28-180 on a night cross-country flight lost engine power due to fuel starvation from the pilot's failure to switch fuel tanks. The pilot was distracted by low ceilings and dark night conditions and did not actively manage the fuel selector. The airplane impacted terrain. The probable cause was the pilot's in-flight mismanagement of the available fuel supply by failure to switch fuel tank position.
NTSB MIA02FA144 (2002, fatal): A Piper PA-28-180 lost engine power on downwind leg shortly after takeoff. The accident resulted from misrouting of fuel lines to the fuel selector, which resulted in fuel starvation. The pilot attempted a forced landing but struck trees and terrain. Contributing was the pilot's inadequate remedial action for conducting an emergency landing.
NTSB WPR24LA178 (2024): A Piper PA-28 lost engine power due to fuel starvation when the pilot placed the fuel selector in an intermediate position — not fully LEFT, not fully RIGHT — and made a forced landing. The probable cause was the pilot's incorrect movement of the fuel selector valve.
NTSB CEN24LA189 (2024): A Piper PA-28-180 on an instructional flight lost all engine power when the student pilot positioned the fuel selector valve between port positions during descent. The probable cause was the student pilot's selection of an improper fuel tank selector position. Contributing to the accident was the instructor's inadequate oversight.
NTSB ERA24LA116 (2024): A Piper PA-28-180 experienced fuel starvation during the second approach to landing after the student pilot failed to switch fuel tanks despite instructor reminders. The probable cause was the student pilot's lack of fuel management during the flight and the flight instructor's inadequate monitoring of his student's fuel management, resulting in fuel starvation and a forced landing to a highway.
The consistent thread across all these events: the Piper PA-28-180's LEFT / RIGHT fuel selector is not a BOTH position. The pilot must actively switch tanks in flight. Fuel starvation from selector mismanagement — running a tank dry, taking off on a near-empty tank, or positioning the selector to OFF or an intermediate position — is the signature failure mode of this airplane. At KVNC, the off-field environment off Runway 04's departure end is open water. An engine failure there is a ditching, not a field landing.
The real accidents cited above occurred at other airports and in other aircraft types — NOT at Venice Municipal Airport. KVNC has its own accident history (see field dominant patterns), but these specific fuel-starvation events happened elsewhere. The scenario is localized to KVNC to make the off-field environment real and consequential for you as a student here.
The key lesson: the PA-28-180 fuel system demands active, deliberate management. Preflight with a fuel stick (not just visual inspection). Brief the fuel selector positions in the POH. Test the switching procedure during run-up. Monitor fuel quantity and tank selection throughout the flight. The engine will not forgive a selector in an intermediate position or OFF.

Debrief — teaching points
The PA-28-180 fuel selector is LEFT / RIGHT / OFF — there is NO BOTH position.
This is the defining feature of the Piper Cherokee 180 fuel system. Unlike some Cessnas, which have a BOTH position, the PA-28-180 requires the pilot to actively switch tanks in flight. Taking off on one tank and forgetting to switch, running a tank dry, or positioning the selector to an intermediate position (not fully LEFT or RIGHT) will result in fuel starvation. The engine will not tolerate a selector in an intermediate or OFF position — it will quit.
Preflight fuel checks must include a fuel stick dip of both tanks.
Visual inspection alone is unreliable — it misses contamination, does not detect actual quantity accurately, and can be fooled by fuel sloshing or tank shape. Dip both tanks with a fuel stick before every flight. Record the quantity. This is the only way to verify you have the fuel you think you have. Many fuel-starvation accidents begin with a preflight that relied on visual inspection and missed a tank that was actually low or contaminated.
Brief the fuel selector positions and test the switching procedure during run-up.
Before takeoff, review the POH fuel selector diagram. Understand which position is LEFT, which is RIGHT, and where OFF is. During run-up, with the engine running, move the selector from LEFT to RIGHT and back to LEFT. Confirm the engine runs smoothly on each tank and that the selector moves fully and snaps into position. A worn detent that does not snap fully into place is a maintenance issue — do not fly the airplane until it is fixed.
Engine starvation shows as a sudden loss of power and a dropping tachometer — it can happen at any altitude.
Fuel starvation is not gradual; it is sudden. The engine will cough, lose power, and the tachometer will unwind. This can happen on initial climb, at cruise altitude, or on approach. The symptom is identical to a carburetor problem or a spark plug issue — which is why you must check the fuel selector first. If the selector is in an intermediate or OFF position, move it fully to LEFT or RIGHT. If the engine recovers, you have diagnosed the problem. If it does not recover, the tank you switched to may be empty.
At KVNC, the off-field environment off Runway 04 is open water — an engine failure there is a ditching.
Runway 04's departure end (heading 045°) is over open water. There is no alternate landing surface ahead. If the engine quits on the Runway 04 departure and altitude is insufficient to return to the airport, the outcome is a controlled ditching in open water. Best glide is 65 KIAS. Cabin door unlatched before water contact. Fuel selector to OFF, mixture to idle cutoff, master off just before impact. Flaps for slowest possible touchdown speed — impact energy rises with the square of speed. Know this before you line up on Runway 04.
Active fuel management throughout the flight is non-negotiable.
Monitor fuel quantity and tank selection continuously. Switch tanks every 15–20 minutes to balance fuel burn and detect a tank that is running dry or contaminated. If one tank runs dry unexpectedly, you have a problem — but you will catch it before the engine quits. Fuel starvation accidents are almost always preventable: they result from a selector in an intermediate position, a tank that was actually empty (missed in preflight), or a failure to switch tanks. All three are pilot errors, not mechanical failures.
