Fuel Tank Confusion on Climb-Out
A Piper Cherokee 180's fuel selector has no BOTH position — switching tanks is not optional, it is mandatory. One mistake at low altitude can end the flight.
The scenario
Departing Brooksville–Tampa Bay Regional Airport (KBKV), Brooksville, FL — Runway 09, climbing out on a 090° heading. Elevation 76 ft MSL. It is a clear, calm morning; OAT 18°C, altimeter 30.02, visibility 10+ SM. A perfect day to fly.
You are a Private pilot with roughly 180 hours total time, mostly in Cessnas and Pipers. This is your second flight in a Piper Cherokee 180 — a low-wing, fixed-gear, carbureted airplane with a LEFT / RIGHT fuel selector and NO BOTH position. You have flown the airplane once before with an instructor; today you are going solo on a local flight to build time and familiarity.
Aircraft: Piper Cherokee 180 (PA-28-180), solo, full fuel (36 gallons usable total — 18 gallons per tank). The airplane was fueled last night; you visually confirmed both tanks full during the preflight. The fuel selector is currently on the LEFT tank. You did not write down the fuel quantity or establish a tank-switching plan before takeoff — a common oversight in familiar, good-weather flying.
You are 400 ft AGL, climbing through 75 KIAS (Vy, best rate of climb), heading 090°, when the engine begins to run rough and lose power. The tachometer is dropping. The runway is behind you. Off Runway 09's departure end (heading 090°) is open developed land — parks, pasture, and medium development. It is good forced-landing terrain, but you are at 400 ft AGL and the window is closing.
Pilot: You — a Private pilot, current, 180 hours total. You have flown Cessnas extensively but are new to the Piper Cherokee 180. You did not review the fuel system diagram before this flight. You did not establish a fuel tank switching interval. You are not wearing a watch with a second hand, so you cannot easily time fuel burn. You did not brief yourself on the fuel selector's LEFT / RIGHT positions or the consequences of selecting OFF or an intermediate position.

The decision
Before we get into the decision tree — what do you already know about the Piper Cherokee 180's 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 improper fuel tank management — the pilot failed to switch fuel tank position. The probable cause was the pilot's in-flight mismanagement of the available fuel supply by failure to switch fuel tank position, which resulted in fuel starvation. Contributing factors were low ceilings and dark night conditions. The pilot and passenger were killed.
NTSB CEN24LA191 (2024): A Piper PA-28-180 on a cross-country personal flight lost engine power due to fuel starvation when the pilot failed to switch fuel tanks while distracted crossing a mountain range. The pilot made a forced landing in a field. The probable cause was the pilot's failure to switch fuel tanks while en route, which resulted in loss of engine power due to fuel starvation.
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, which resulted in fuel starvation and a total loss of engine power. 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 the student's fuel management, resulting in fuel starvation and a forced landing to a highway.
NTSB CEN24LA108 (2024): A Piper PA-28-180 on an instructional flight experienced fuel starvation when the student pilot inadvertently positioned the fuel selector toward the OFF position during a fuel tank change. The flight instructor performed a forced landing to a field. The probable cause was the student pilot's improper movement of the fuel selector to the OFF position, which resulted in fuel starvation and a total loss of engine power.
The real accidents cited above occurred at other airports and in other aircraft types — NOT at Brooksville–Tampa Bay Regional Airport (KBKV). KBKV has its own accident history (hard landings, forced landings, runway excursions dominate the field's corpus), but these specific fuel starvation events happened elsewhere. The scenario is localized to KBKV to make the off-field environment real and consequential for you as a student here.
The consistent thread across all these events: the Piper Cherokee 180's fuel selector has LEFT, RIGHT, and OFF positions — there is NO BOTH position. The pilot must actively switch tanks during flight. Running a selected tank dry while the other tank has fuel is the signature starvation trap. Positioning the selector in an intermediate position (between LEFT and RIGHT, or toward OFF) restricts fuel flow and causes engine roughness, power loss, and eventual engine failure. The fix — confirming the selector is fully on LEFT or RIGHT, establishing a tank-switching interval before takeoff, and monitoring fuel quantity — is simple. The failure is always a delay or inattention.
Off Runway 09's departure end at KBKV, the off-field environment is open developed land (parks, pasture, medium development) — good forced-landing terrain. A delayed response to engine roughness at 400 ft AGL means a tight forced landing, not a ditching. Know this before you line up on Runway 09.
Key lesson — The Piper Cherokee 180's fuel selector has no BOTH position. LEFT and RIGHT are the only usable positions; OFF cuts all fuel flow. The pilot must actively switch tanks during flight — fuel does not automatically balance. Establish a fuel tank switching interval (e.g., every 15 minutes) before takeoff and write it down. At the first sign of engine roughness or unexplained RPM loss, check the fuel selector position immediately — confirm it is fully on LEFT or RIGHT, not in an intermediate position. At low altitude over open terrain, the decision window is measured in seconds — not minutes. Off Runway 09 at KBKV, the off-field environment is open developed land: a delayed response means a tight forced landing.
Debrief — teaching points
The Piper Cherokee 180 has no BOTH fuel position — active tank management is mandatory.
Unlike the Cessna 172, which has a BOTH position that automatically feeds from both tanks, the PA-28-180's fuel selector has only LEFT, RIGHT, and OFF. The pilot must actively switch tanks during flight. Fuel does not automatically balance between tanks. Running a selected tank dry while the other tank has fuel is the signature starvation trap in the Cherokee 180. This is not a design flaw; it is the system you are operating. Know it before you fly.
Establish a fuel tank switching interval BEFORE takeoff and write it down.
A common interval is every 15 minutes: LEFT for 15 minutes, then RIGHT for 15 minutes, alternating. Write this plan on your kneeboard or flight log before you line up on the runway. Set a timer or use a clock with a second hand to track the interval. Do not rely on memory or a vague sense of time — workload and distraction will defeat you. The NTSB CEN24LA191 pilot was distracted crossing a mountain range and forgot to switch tanks. The ERA24LA116 student pilot failed to switch despite instructor reminders. The system requires discipline.
Confirm the fuel selector is fully on LEFT or RIGHT — never in an intermediate position.
An intermediate position (between LEFT and RIGHT, or toward OFF) restricts fuel flow and causes engine roughness, power loss, and eventual engine failure. This is not a gradual degradation; it is a sudden loss of power. The NTSB CEN24LA189 student pilot positioned the selector between port positions and lost all engine power. The NTSB CEN24LA108 student pilot moved the selector toward OFF and lost all engine power. At the first sign of engine roughness or unexplained RPM loss, check the fuel selector position immediately — confirm it is fully seated on LEFT or RIGHT.
At low altitude, engine roughness is a fuel system problem until proven otherwise.
In the PA-28-180, engine roughness at low altitude is most likely a fuel selector issue (wrong position, intermediate position, or OFF), fuel contamination, or a loose fuel line. Carburetor heat is a secondary check — carb ice is possible but less likely in clear, calm conditions. Check the fuel selector position FIRST. Confirm the selector is fully on LEFT or RIGHT. If the roughness persists, then consider carb heat, mixture adjustment, or other diagnostics. But the fuel selector is the first and most likely culprit.
Off Runway 09 at KBKV, the off-field environment is open developed land — good forced-landing terrain.
The departure end of Runway 09 (heading 090°) is open developed land: parks, pasture, and medium development. There is no water, no mountains, no dense forest. If the engine fails on the Runway 09 departure and altitude is insufficient to return to the airport, the outcome is a controlled forced landing in open terrain — not a ditching, not a crash into trees. This is survivable terrain. Know this before you line up on Runway 09. Best glide is 65 KIAS. Flaps for slowest possible touchdown speed. Smooth touchdown in the best available field.
