Fuel Tank Confusion on Climb
A Piper Cherokee 180's fuel selector has no BOTH position — switching tanks mid-flight is not optional, it is mandatory. One mistake, one dead engine, one forced landing.
The scenario
Departing Lakeland Linder International Airport (KLAL), Lakeland, FL — Runway 10, climbing out on a 090° heading. Elevation 142 ft MSL. It is a clear, calm morning: OAT 18°C, altimeter 30.01, visibility 10 SM. Light winds from the northeast. Perfect VFR conditions.
You are a Private pilot with 180 hours total time, 45 hours in the Piper Cherokee 180. This is a personal cross-country flight to a small airport 120 nm northeast. You filed VFR, received a standard briefing, and conducted a thorough preflight. Fuel: both tanks full (36 gallons usable total — 18 gallons per tank). You are within weight and balance limits.
You are 800 ft AGL, climbing at 74 KIAS (Vy), heading 090°, when you notice the engine beginning to run rough. The tachometer is unwinding — RPM dropping. The engine is not surging or cutting out; it is just losing power, and the roughness is increasing. You are still over the departure area, with open developed land (parks, low-density development) off the right wing and medium development to the left.
Aircraft: Piper Cherokee 180 (PA-28-180), solo, full fuel. Lycoming O-360-A, carbureted, fixed-pitch prop, steam panel. Fuel selector is currently on LEFT tank. You switched to LEFT at the start of the climb — a normal procedure. Nothing was written up; the airplane was airworthy at departure.
Pilot: You — a Private pilot, current, 180 hours total, 45 hours in type. You did not apply carburetor heat during the run-up because the engine ran smoothly. You did not apply it after takeoff because you were focused on the climb and the weather was clear. You are not yet thinking about fuel tank management — the flight is only 10 minutes old.

The decision
Before we get into the decision tree — what do you already know about the Piper Cherokee 180's fuel system and fuel tank management? (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 tank position. The pilot did not actively manage the fuel selector during the flight, allowing the selected tank to run dry. The accident was fatal. The probable cause was the pilot's in-flight mismanagement of the available fuel supply by failure to switch fuel tank position.
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 was so focused on terrain avoidance that fuel management was neglected. The airplane made a forced landing in a field. The probable cause was the pilot's failure to switch fuel tanks while en route.
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 (LEFT and RIGHT) during descent. The student did not understand that an intermediate position restricts fuel flow. The instructor did not catch the error until power was lost. The probable cause was the student pilot's selection of an improper fuel tank selector position, with contributing factor of inadequate instructor 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 student was so focused on the approach that fuel management was forgotten. The airplane made a forced landing on a highway. The probable cause was the student pilot's lack of fuel management and the flight instructor's inadequate monitoring.
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 student moved the selector too far, blocking fuel flow entirely. 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.
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 during maintenance — the fuel lines were connected backward, so the selected tank was not the one supplying fuel. The pilot attempted a forced landing but struck trees and terrain. The probable cause was the misrouting of the fuel lines to the fuel selector, which resulted in the use of a fuel tank with inadequate fuel supply.
The real accidents cited above occurred at other airports and in other aircraft — NOT at Lakeland Linder International Airport. KLAL has its own accident history (see field dominant patterns: LOSS_OF_CONTROL_INFLIGHT 23.7%, LOSS_OF_CONTROL_GROUND 19.4%, FORCED_LANDING 17.2%), but these specific fuel starvation events happened elsewhere. The scenario is localized to KLAL 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 no BOTH position. The pilot MUST actively switch tanks during flight. Running a selected tank dry — or taking off on a near-empty tank — is the signature starvation trap. The fix is simple: establish a fuel tank switching discipline before takeoff, monitor fuel quantity continuously, and switch tanks proactively before starvation occurs. The failure is always a delay or a distraction.
Key lesson — The Piper Cherokee 180's fuel selector has LEFT / RIGHT positions only — there is no BOTH position. The pilot must actively switch tanks during flight. At 800 ft AGL on climb-out, the decision window is measured in seconds. Fuel starvation from a selected tank running dry is the signature PA-28-180 accident. Establish a fuel tank switching plan before takeoff, monitor fuel state continuously, and switch tanks proactively. If the engine loses power and carburetor heat does not help, switch tanks immediately. Off Runway 10's climb-out at KLAL, the off-field environment is marginal — a forced landing there is survivable but not comfortable. The correct response to engine roughness in the PA-28-180 is: (1) carburetor heat (rule out carb ice), (2) fuel selector switch (rule out starvation), (3) if both fail, establish best glide and prepare for a forced landing.
Debrief — teaching points
The PA-28-180 fuel selector has no BOTH position — switching tanks is mandatory, not optional.
Unlike Cessnas (which have a BOTH position), the Piper Cherokee 180 has LEFT / RIGHT positions only. The pilot must actively switch tanks during flight. There is no 'both tanks feed the engine' option. This is the signature design difference that makes fuel starvation a PA-28-180-specific accident. Establish a fuel tank switching discipline before takeoff: plan which tank you will use for takeoff and climb, when you will switch to the other tank, and how you will monitor fuel state. Execute that plan consistently.
Running a selected tank dry is the classic PA-28-180 starvation trap.
The NTSB accident corpus shows a consistent pattern: the pilot selects one tank (usually the LEFT tank for takeoff and climb), flies for 30–60 minutes, and does not switch to the other tank. The selected tank runs dry. The engine loses power. The pilot does not immediately recognize fuel starvation as the cause and does not switch tanks until it is too late. The fix is simple: establish a fuel tank switching interval (e.g., switch every 30 minutes) and execute it religiously. Do not wait for the engine to tell you the tank is empty.
Positioning the fuel selector between LEFT and RIGHT (intermediate position) can cause starvation even if fuel is available.
NTSB CEN24LA189 and CEN24LA108 both show accidents where the student pilot moved the fuel selector to an intermediate position — between LEFT and RIGHT, or toward OFF — and blocked fuel flow. The selector must be fully in one position or the other. There is no 'between' position. If you are switching tanks, move the selector decisively to the new position and confirm it is fully seated. Do not leave it in an intermediate position.
At KLAL Runway 10, an engine failure on climb-out is a forced landing in marginal off-field environment.
The off-field environment off Runway 10's climb-out (heading 090°) is marginal: low-density development, open developed areas (parks, large lots), and some dense development. There is no open water, but there is also no ideal landing surface. A forced landing there is survivable but not comfortable. Best glide is 65 KIAS. Flaps for slowest possible touchdown speed — impact energy rises with the square of speed. Scan for open developed areas (parks, large lots) and avoid dense development and trees. Know this before you line up on Runway 10.
Engine roughness in the PA-28-180 requires a two-step diagnostic: carburetor heat, then fuel selector.
When the engine loses power or runs rough, the first response is carburetor heat (rule out carb ice in conducive conditions). If carb heat does not help, the second response is to switch fuel tanks (rule out fuel starvation). The PA-28-180's carbureted O-360-A is susceptible to both carb ice and fuel starvation. Execute both diagnostics in sequence. If both fail, establish best glide at 65 KIAS and prepare for a forced landing.
Fuel tank switching discipline must be established BEFORE takeoff, not during flight.
The NTSB accident corpus shows that pilots who establish a fuel tank switching plan before takeoff (e.g., 'LEFT tank for takeoff and climb, switch to RIGHT at 15 minutes, switch back to LEFT at 30 minutes') execute it consistently. Pilots who do not establish a plan forget to switch tanks, especially when distracted by navigation, weather, or other tasks. Write your fuel tank switching plan in the flight plan or on a notepad. Execute it on schedule. Do not rely on memory or on the engine to tell you when to switch.
