Fuel Tank Confusion on Initial Climb
A Piper Cherokee 180's LEFT/RIGHT fuel selector demands active management — one mistake at low altitude over dense development is unforgiving
The scenario
Departing Clearwater Air Park (KCLW), Clearwater, FL — Runway 16, climbing out on a 155° heading. Elevation 71 ft MSL. It is a clear, calm morning: OAT 22°C, dew point 18°C, altimeter 29.98. Visibility 10 SM. Light winds from the east. A routine local flight in a Piper Cherokee 180.
You are 300 ft AGL, climbing through 70 KIAS (just above Vy of 74 KIAS, still accelerating), heading 155°, when the engine begins to lose power. The tachometer is unwinding. The engine is not rough — it is simply running at reduced RPM, as if the throttle has been pulled back. You have not touched the throttle. The airplane is still climbing, but the rate is dropping.
Off Runway 16's climb-out (heading 155°), the off-field environment is dense development — low-density residential, medium development, scattered parks. There is no open field, no water, no clear alternate landing surface. The terrain is built-up. An engine failure at 300 ft AGL over this environment is a forced landing into developed area, not a field landing.
Aircraft: Piper Cherokee 180, solo, full fuel in both tanks (LEFT and RIGHT), within limits. Lycoming O-360-A, carbureted, fixed-pitch prop, fixed gear, steam panel. The airplane was airworthy at preflight. Nothing was written up.
Pilot: you — a Private pilot, current, roughly 180 hours total. You are familiar with the Cherokee 180's fuel system in principle: LEFT tank, RIGHT tank, no BOTH position. You must actively switch tanks. You did a standard preflight and run-up. The fuel selector was on LEFT for the run-up and takeoff. You did not think about switching tanks on initial climb — it is a short local flight.

The decision
Before we get into the decision tree — what do you already know about the Piper Cherokee 180's fuel system and fuel starvation? (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 accident occurred during cruise; the pilot did not switch from the LEFT tank to the RIGHT tank as planned, ran the LEFT tank dry, and the engine quit. The pilot attempted a forced landing in darkness but struck terrain. The probable cause was the pilot's in-flight mismanagement of the available fuel supply by failure to switch fuel tank position, with low ceilings and dark night conditions as contributing factors.
NTSB CEN24LA191 (2024): A Piper PA-28-180 on a cross-country 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 focused on terrain avoidance and did not monitor fuel management. The engine quit during descent. The pilot made a forced landing in a field. The probable cause was the pilot's failure to switch fuel tanks, resulting 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 (intermediate position) during descent. The student did not understand the fuel selector mechanics; the instructor did not catch the error. The engine quit. The student made a forced landing in a field. The probable cause was the student pilot's selection of an improper fuel tank selector position, with contributing factor of inadequate instructor oversight.
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, resulting in total loss of engine power.
The common thread across all these events: the Piper Cherokee 180's LEFT/RIGHT fuel selector is unforgiving. There is no BOTH position. The pilot must actively switch tanks. An intermediate position, an OFF position, or a failure to switch to the tank with usable fuel results in total power loss. At low altitude, that is a forced landing. At night or over terrain, it is often fatal. The real accidents cited above occurred at other airports and in other conditions — NOT at KCLW on a clear morning. KCLW has its own accident history (see field dominant patterns), but these specific events happened elsewhere. The scenario is localized to KCLW to make the off-field environment real and consequential for you as a student here.
Off Runway 16's climb-out (heading 155°), the off-field environment is dense development — low-density residential, medium development, scattered parks. There is no open field, no water, no clear alternate landing surface. An engine failure at 300 ft AGL over this environment is a forced landing into developed area, not a field landing. This is the NLCD ground cover off that runway end.
The lesson: the Piper Cherokee 180's fuel selector is a critical system. It must be firmly seated on LEFT or RIGHT. An intermediate position is a total power loss. Preflight must include a positive check of fuel selector detent and movement. In-flight fuel management must include a planned fuel tank switch at a known time or altitude — not ad hoc, not when distracted. The pilot must know which tank is feeding the engine at all times.
Key lesson — The Piper Cherokee 180 has no BOTH fuel position — the pilot must actively switch tanks. An intermediate position, an OFF position, or a failure to switch to the tank with usable fuel results in total power loss. At low altitude, that is a forced landing. Preflight must include a positive check of fuel selector detent and movement. In-flight fuel management must include a planned fuel tank switch at a known time or altitude. Know which tank is feeding the engine at all times.
Debrief — teaching points
The Piper Cherokee 180 has no BOTH fuel position — the pilot must actively switch tanks.
Unlike Cessnas (which have a BOTH position), the Cherokee 180's fuel selector has only LEFT and RIGHT positions. There is no BOTH. The pilot must actively move the selector from LEFT to RIGHT (or vice versa) to feed the engine from the other tank. An intermediate position — the selector between LEFT and RIGHT — results in total power loss. The engine cannot feed from either tank. This is the signature Cherokee 180 accident: the pilot forgets to switch tanks, runs one tank dry, and the engine quits. At low altitude, that is a forced landing.
Preflight must include a positive check of fuel selector detent and movement.
During preflight, move the fuel selector through its full range: LEFT (firm detent), RIGHT (firm detent), and confirm it does not slip into an intermediate position. A worn detent or a selector that does not seat firmly is a maintenance issue. Do not fly the airplane until it is corrected. In-flight, the selector must remain firmly seated on LEFT or RIGHT. If it slips into an intermediate position, power is lost immediately.
Plan fuel tank switches in advance — at a known time or altitude, not ad hoc.
Do not wait until one tank is nearly empty to switch. Plan the switch at a known time (e.g., +1 hour, +3 hours) or altitude (e.g., at 2,000 ft on climb, at 1,500 ft on descent). Announce the switch to yourself: 'Switching to RIGHT tank at 1,500 ft.' Verify the selector is firmly seated. Monitor fuel flow and engine instruments for 30 seconds to confirm the engine is feeding from the new tank. This discipline prevents the 'forgot to switch' accident.
Know which tank is feeding the engine at all times.
At any point in the flight, you must be able to answer: 'Which tank is the engine feeding from right now?' If you cannot answer that question, you do not have control of the fuel system. Fuel starvation is a total power loss. At low altitude, it is a forced landing. Know your fuel state, know which tank is selected, and know which tank has usable fuel.
An intermediate fuel selector position is a total power loss — immediate action required.
If you notice the tachometer unwinding and the engine losing power at low altitude, the first diagnostic check is the fuel selector. Verify it is fully on LEFT or RIGHT. If it is in an intermediate position, move it fully to LEFT or RIGHT immediately. Power should return. If the selector is in an intermediate position, the engine will not feed from either tank — this is a total power loss waiting to happen. Do not delay.
At KCLW Runway 16, the off-field environment is dense development — no clear alternate landing surface.
Off Runway 16's climb-out (heading 155°), the off-field environment is dense residential and medium development. There is no open field, no water, no clear alternate landing surface. An engine failure at 300 ft AGL over this environment is a forced landing into developed area. This is not a worst-case scenario; it is the geographic reality. Know this before you line up on Runway 16. If the engine fails on climb-out, your options are limited: return to the airport or land in developed area.
