Fuel Tank Discipline at Tampa International
A Piper Cherokee 180 on approach: fuel selector position, tank exhaustion, and the decision to land or divert — dense development surrounds the field
The scenario
Departing Tampa International Airport (KTPA), Tampa, FL — Runway 19L, a 2-hour personal cross-country flight to a small field inland. Elevation 26 ft MSL. The runway is essentially at sea level; the surrounding terrain is dense urban development — parks, commercial strips, and residential neighborhoods in all directions.
It is a warm, hazy Florida afternoon: OAT 31°C, altimeter 29.91, scattered clouds at 3,500 ft. Visibility 10 SM. You are in Class B airspace (KTPA is a towered, 24-hour ATCT with TRACON). The approach to Runway 19L (heading 182°) is over dense development; the climb-out off Runway 19L (heading 182° southbound) is also over dense development and pasture — no open water, but no easy off-field landing either.
You filed a VFR flight plan. Fuel: before departure, you visually checked both tanks — left tank appeared full, right tank appeared three-quarters full. You did not dip the tanks with a stick; you relied on the sight gauges. You took off on the left tank (the standard practice in the PA-28-180 is to depart on the left, then switch to the right tank after 30 minutes or so to balance consumption). You are now 1 hour 45 minutes into the flight, approaching KTPA for landing. The fuel selector is still on LEFT.
Aircraft: Piper PA-28-180, solo, within limits. Lycoming O-360-A carbureted engine, fixed-pitch prop, fixed landing gear, steam panel. Fuel selector: LEFT / RIGHT (no BOTH position). The left tank has been feeding the engine for 1 hour 45 minutes. You have not switched to the right tank.
Pilot: you — a Private pilot, current, roughly 250 hours total. You are familiar with the PA-28-180's fuel system in principle: LEFT / RIGHT selector, no BOTH, and the discipline to switch tanks regularly. But on this flight, you were heads-down on navigation, managing the descent, and coordinating with KTPA approach. You did not actively monitor fuel quantity or tank selection. The right tank, which you assumed was three-quarters full, is actually your reserve. The left tank, which you have been feeding from for 1 hour 45 minutes, is now nearly empty.

The decision
Before we get into the decision tree — what do you know about fuel tank management in the PA-28-180? (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. The pilot had failed to switch fuel tanks during the flight, running the left tank dry while the right tank had usable fuel. The accident resulted in impact with 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. This accident occurred at another airport — NOT at KTPA — but the fuel starvation mechanism is identical to the scenario you just flew.
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 accident resulted in 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 accident resulted in a forced landing on a highway. 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.
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 consistent thread: the PA-28-180's LEFT / RIGHT fuel selector (no BOTH position) is the signature trap. Pilots who forget to switch tanks, or who switch to an empty tank, or who position the selector between ports, experience total engine failure. At KTPA, the off-field environment is dense development — parks, commercial strips, residential neighborhoods. A forced landing in that environment is survivable only if the runway is within glide distance. The real accidents cited above occurred at other airports and in other flight phases — but the fuel starvation mechanism is universal to the PA-28-180.
The KTPA environment: Runway 19L's climb-out (heading 182° southbound) is over dense development and pasture — no open water, but no easy off-field landing either. An engine failure on the Runway 19L departure would force a landing in an urban area. The approach to Runway 19L is also over dense development. The only safe outcome is to reach the runway with power, or to glide to the runway if power is lost on approach. Fuel tank discipline — switching to the right tank well before descent — is the entire lesson.
The real events happened at other airports — NOT at Tampa International. KTPA has its own accident history (see field dominant patterns: FORCED_LANDING 22.2%, LOSS_OF_CONTROL_INFLIGHT 11.1%), but these specific fuel starvation accidents happened elsewhere. The scenario is localized to KTPA to make the off-field environment real and consequential for you as a student here.
Key lesson — The PA-28-180's fuel system is unforgiving. There is no BOTH position — the pilot must actively switch tanks. Standard practice is to depart on the left tank, switch to the right tank after 30 minutes, and complete all tank switching well before descent. Sight gauges are unreliable; dip the tanks before departure or calculate fuel consumption. Fuel tank switching must be completed during cruise, not during approach when workload is high and attention is divided. Running one tank dry while the other tank has usable fuel is the signature fuel starvation accident in this airplane. At KTPA, the off-field environment is dense development — a forced landing in that environment is survivable only if the runway is within glide distance. Fuel tank discipline is the entire lesson.
Debrief — teaching points
The PA-28-180 has no BOTH position — fuel tank switching is mandatory.
Unlike Cessnas (which have a BOTH position), the PA-28-180 fuel selector is LEFT / RIGHT only. The pilot must actively switch tanks. Standard practice is to depart on the left tank, switch to the right tank after 30 minutes to balance consumption, and complete all tank switching well before descent. Forgetting to switch tanks, or switching to an empty tank, or positioning the selector between ports, results in total engine failure. This is not a system failure; it is a pilot error trap built into the airplane's design. Know this before you fly the PA-28-180.
Sight gauges are unreliable — dip the tanks or calculate consumption.
The fuel quantity sight gauges in the PA-28-180 can be inaccurate due to aircraft attitude, vibration, and gauge wear. A tank that appears three-quarters full may actually be nearly empty. The only reliable fuel quantity check is a physical dip stick (a long stick inserted into the filler neck to measure fuel depth) or a known consumption calculation (fuel burned per hour × flight time = fuel remaining). Before every flight, dip both tanks or calculate expected fuel remaining based on flight time and fuel burn rate. Do not rely on sight gauges alone.
Fuel tank switching must be completed well before descent — not during approach.
Approach workload is high: managing descent, accepting vectors, configuring the airplane, and coordinating with ATC. Fuel tank switching during approach is a distraction and a risk. The correct procedure is to switch tanks during cruise, well before descent. In the PA-28-180, standard practice is to switch to the right tank after 30 minutes of cruise. If you are approaching an airport and have not yet switched tanks, switch immediately — do not wait until final approach. A fuel tank switch on final approach is a trap: if the right tank is also empty, or if the switch causes a momentary power loss, you may not have time to recover.
Running one tank dry while the other has usable fuel is the signature PA-28-180 accident.
The NTSB accident corpus for the PA-28-180 shows a consistent pattern: pilots who forget to switch tanks, or who switch to an empty tank, experience total engine failure. The accidents cited in this scenario (DFW05FA028, CEN24LA191, CEN24LA189, ERA24LA116, CEN24LA108) all resulted from fuel mismanagement — failure to switch tanks, improper selector position, or switching to an empty tank. At KTPA, the off-field environment is dense development. A forced landing in that environment is survivable only if the runway is within glide distance. Fuel tank discipline is the entire lesson.
At KTPA, the off-field environment is dense development — no easy forced-landing option.
KTPA is surrounded by dense urban development: parks, commercial strips, residential neighborhoods. The climb-out off Runway 19L (heading 182° southbound) is over dense development and pasture. The approach to Runway 19L is also over dense development. There is no open water, no large field, no road — just urban terrain. An engine failure on the Runway 19L departure would force a landing in an urban area with no good off-field option. The only safe outcome is to reach the runway with power, or to glide to the runway if power is lost on approach. Fuel tank discipline — switching to the right tank well before descent — is the entire lesson.
Best glide in the PA-28-180 is 65 KIAS — establish it immediately if power is lost.
If the engine quits due to fuel starvation, establish 65 KIAS best glide immediately. At 65 KIAS, the PA-28-180 glides approximately 8–10:1 (8–10 feet forward for every 1 foot of altitude lost). If you are on final approach to KTPA and lose power, 65 KIAS best glide will carry you to the runway. If you are on the departure, 65 KIAS best glide will carry you to the nearest open area. Do not try to stretch the glide with a high nose attitude — that will only slow the airplane and reduce glide distance. Establish 65 KIAS and glide.
