Power Loss on Initial Climb
Partial engine failure in a Piper Cherokee 180 — carburetor ice, fuel starvation, or maintenance? The decision clock is short and the terrain off each runway end is different.
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 warm, humid Florida morning in late spring: OAT 26°C, dew point 21°C, altimeter 29.94. Scattered clouds at 2,500 ft, light rain shower two miles to the northeast. Visibility 8 SM. Classic Gulf Coast conditions — warm, moist air and exactly the environment the FAA icing probability chart marks as 'serious icing at glide power, moderate icing at cruise power.'
You are 500 ft AGL, climbing through 74 KIAS (Vy), heading 090°, when the engine begins to run rough. Power is noticeably down — the tachometer is dropping. The off-field environment to the east (Runway 10 climb-out) is mostly low-density development, open developed areas (parks/large lots), and some dense development — workable forced-landing terrain, but not ideal. KLAL's tower is 24-hour and is open; you are in Class D airspace (ceiling 2,600 MSL).
Aircraft: Piper Cherokee 180, solo, full fuel (48 gallons total — 24 gal left tank, 24 gal right tank), within limits. Carbureted Lycoming O-360-A, fixed-pitch prop, steam panel, fuel selector on LEFT (the tank you selected for takeoff). Nothing was written up; the airplane was airworthy at departure.
Pilot: you — a Private pilot, current, roughly 180 hours total. 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 heads-down on the climb and focused on the heading. You selected the LEFT tank for takeoff (a standard practice), but you did not verify fuel quantity in either tank before flight — the fuel gauges are notoriously unreliable in the Cherokee 180, and you relied on a visual inspection that was cursory.

The decision
Before we get into the decision tree — what do you already know about the Piper Cherokee 180's fuel system and engine failure modes? (Pick all that apply; this records your baseline.)
What the record shows
What the NTSB files show
NTSB ATL03LA148 (2003): A Piper PA-28-180 on a personal flight experienced engine power loss during takeoff climb after extended ground operation in conditions favorable for carburetor icing. The probable cause was the pilot's failure to apply carburetor heat when weather conditions were favorable for carburetor icing. The airplane was not damaged, but the forced landing was precarious.
NTSB DEN07CA035 (2006): A Piper PA-28-180 on a personal flight lost engine power on base leg due to carburetor icing and made a forced landing attempt on a road. The pilot swerved to avoid car lights and struck a tree, resulting in substantial damage. The probable cause was loss of power due to carburetor icing in conditions conducive to serious icing, with contributing factors including unsuitable terrain and the tree obstacle.
NTSB NYC03LA096 (2003): A Piper PA-28-180 on an instructional flight experienced partial engine power loss on initial climb after takeoff and made a forced landing in a field. The probable cause was an inadequate 100-hour inspection by maintenance personnel, which resulted in a loose fuel line connection. Night conditions were a contributing factor.
NTSB ANC25LA094 (2025): A Piper PA-28-180 experienced partial engine power loss with vibration during climb-out following a low-altitude runway inspection pass and made a forced landing in terrain. The accident resulted from engine malfunction that prevented continued climb.
The real accidents cited above occurred at other airports and in other aircraft types — 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 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: partial power loss in the PA-28-180 on initial climb is insidious. It can result from carburetor ice (the most common), fuel starvation (running a selected tank dry, or taking off on a near-empty tank), or maintenance defects (loose fuel line, inadequate inspection). The first symptom is always engine roughness and a dropping tachometer. The fix — apply full carburetor heat immediately, or switch fuel tanks if carb heat doesn't work — is simple. The failure is always a delay.
At KLAL, the off-field environment matters: off Runway 10 climb-out (heading 090°), the terrain is low-density development and open areas — workable forced-landing terrain. Off Runway 28 climb-out (heading 270°), the terrain is medium development, evergreen forest, and low-density development — much less favorable. Your runway selection at departure, and your decision to return to the airport or land ahead, both depend on understanding the terrain you are climbing out into.
Key lesson — In warm, moist Gulf Coast air, the PA-28-180's carbureted O-360-A can accumulate serious carburetor ice even at cruise power and above-freezing temperatures. Apply full carburetor heat at the first sign of engine roughness or unexplained RPM loss. At low altitude on initial climb, the decision window is measured in seconds — not minutes. The PA-28-180 has no BOTH fuel position; you must actively switch tanks. Running a selected tank dry is the signature starvation trap. Know which tank you are on, and be ready to switch if carb heat doesn't work.
Debrief — teaching points
Carburetor ice forms in conditions you would not expect.
The FAA icing probability chart shows 'serious icing at glide power' at temperatures between roughly 20°C and 30°C when relative humidity is high — exactly the Gulf Coast afternoon conditions at KLAL. You do not need visible ice, freezing temperatures, or IMC. Warm, moist air at reduced power is the classic carb-ice environment. The PA-28-180's Lycoming O-360-A is carbureted; it has no fuel injection or alternate air system. Carburetor heat is the only tool. Extended ground operation (taxiing, run-up, holding for takeoff clearance) in these conditions is particularly conducive to ice formation in the carburetor throat.
The first symptom is subtle — a dropping tachometer and engine roughness.
In a fixed-pitch airplane like the PA-28-180, carburetor ice first shows as engine roughness and an unexplained RPM decrease. There is no dramatic power cut. Pilots who are not actively monitoring the tachometer miss the early warning. By the time the roughness is obvious, significant ice has accumulated. Scan the tachometer as part of your regular instrument scan, especially in conducive conditions. On initial climb, your scan should include the tachometer every 5–10 seconds.
Apply full carburetor heat — not partial — and expect an initial RPM drop.
When you apply carb heat to an iced carburetor, the RPM will drop further before it rises. This is expected and normal: the heat is melting ice and the resulting water is briefly disrupting combustion. Do not remove carb heat when the RPM drops — that is the heat working. Hold it full on. The RPM will recover as the ice clears, typically within 15–30 seconds depending on ice accumulation. Partial carb heat can worsen the situation by partially melting ice into water ingestion without fully clearing the restriction.
The PA-28-180 has LEFT / RIGHT fuel selector — no BOTH position. You must actively switch tanks.
Unlike Cessnas, the PA-28-180 has no BOTH position on the fuel selector. You must actively switch between LEFT and RIGHT tanks. Running a selected tank dry — or taking off on a near-empty tank — is the signature starvation trap in Pipers. Before takeoff, verify fuel quantity in both tanks visually (the fuel gauges are notoriously unreliable). During flight, plan your tank switching: typically, fly on one tank for 30–45 minutes, then switch to the other. Keep track of which tank you are on. If the engine runs rough and carb heat doesn't work, switch tanks immediately — it may be fuel starvation, not ice.
Off Runway 10 climb-out at KLAL, the terrain is workable forced-landing terrain.
The off-field environment off Runway 10 climb-out (heading 090°) is mostly low-density development, open developed areas (parks, large lots), and some dense development. This is workable forced-landing terrain — not ideal, but far better than the dense development and evergreen forest off Runway 28. If you experience an engine failure on the Runway 10 departure and cannot return to the airport, landing in the low-density development and open areas ahead is a defensible, survivable option. Know this before you line up on Runway 10.
Proactive carb heat use in conducive conditions is not optional.
The PA-28-180 POH and the FAA Pilot's Handbook of Aeronautical Knowledge both recommend applying carburetor heat when conditions are conducive to icing — before the symptom appears. In a Gulf Coast summer departure, with OAT near 26°C and dew point near 21°C, that means applying carb heat during the run-up check (and confirming the expected RPM drop, then recovery) and considering its use during climb in visible moisture or high humidity. Waiting for the roughness to appear at 500 ft AGL on initial climb is waiting too long.
Maintenance quality matters: a loose fuel line or inadequate inspection can cause partial power loss.
NTSB NYC03LA096 documents a PA-28-180 that experienced partial power loss on initial climb due to a loose fuel line connection that was missed in a 100-hour inspection. An inadequate inspection is a maintenance failure, but it is also a pilot responsibility: if you notice anything unusual during the preflight (fuel smell, loose fittings, oil residue), do not fly. If you experience an engine anomaly at low altitude, a precautionary landing and a maintenance inspection are not optional — they are the correct next step.
