Power Loss on Initial Climb
Partial engine failure in a Piper Cherokee 180 — carburetor ice, fuel starvation, or maintenance failure — and a decision tree with real off-field consequences
The scenario
Departing Sarasota Bradenton International Airport (KSRQ), Runway 04, climbing out on a 038° heading. Elevation 30 ft MSL. The runway is essentially at sea level; you are in Class C airspace (ceiling 4,000 MSL). KSRQ tower is active (part-time 0600–0000 local).
It is a warm, humid Florida morning in late spring: OAT 26°C, dew point 21°C, altimeter 29.94. Scattered clouds at 2,800 ft, light rain showers visible to the southeast. Visibility 9 SM. The conditions are classic Gulf Coast — warm, moist, and exactly the environment the FAA icing probability chart marks as 'serious icing at glide power, moderate icing at cruise power.' The off-field environment off Runway 04's climb-out (heading 038°) is marginal: medium development, wooded wetland, low-density development — not ideal for a forced landing, but workable.
You are 350 ft AGL, climbing through 70 KIAS (near Vy of 74 KIAS), heading 038°, when the engine begins to run rough. Power is noticeably down — the tachometer is unwinding. You have roughly 30 seconds of useful decision time before altitude becomes critical.
Aircraft: Piper Cherokee 180, solo, 45 gallons usable fuel, within limits. Carbureted Lycoming O-360-A, fixed-pitch prop, steam panel. The left tank was full at start; the right tank was at 1/4 tank. 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.
Pilot: you — a Private pilot, current, roughly 180 hours total, with 20 hours in type (PA-28-180). You are familiar with the fuel selector (LEFT / RIGHT — no BOTH position). The airplane was airworthy at departure; the 100-hour inspection was completed 8 hours ago by the flight school's maintenance.

The decision
Before we get into the decision tree — what do you already know about engine failure and fuel management in the Piper Cherokee 180? (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 pilot had not applied carburetor heat prior to takeoff, allowing ice to form in the induction system. The probable cause was the pilot's failure to use carburetor heat when weather conditions were favorable for icing.
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, with contributing factors including unsuitable terrain available for forced landing 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 accident resulted from an inadequate 100-hour inspection that failed to detect a loose fuel line connection. The pilot's 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 Sarasota Bradenton International Airport. KSRQ has its own accident history (see field dominant patterns: LOSS_OF_CONTROL_GROUND 19.2%, FORCED_LANDING 15.4%, RUNWAY_EXCURSION 11.5%, HARD_LANDING 11.5%, LOSS_OF_CONTROL_INFLIGHT 11.5%), but these specific events happened elsewhere. The scenario is localized to KSRQ to make the off-field environment real and consequential for you as a student here.
The consistent thread across all these events: engine failure in the PA-28-180 — whether from carburetor icing, fuel starvation, or maintenance failure — happens at the worst possible time: on takeoff or initial climb, when altitude is critically low. The fix for carburetor icing is immediate full carb heat. The fix for fuel starvation is understanding that the PA-28-180 has LEFT / RIGHT fuel selector with NO BOTH position — the pilot must actively switch tanks, and running a selected tank dry is the signature trap. The fix for maintenance failure is a thorough preflight and a critical eye on any anomaly during run-up. All three are preventable.
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 the Runway 04 departure, the decision window is measured in seconds — not minutes. Off Runway 04 at KSRQ, the off-field environment is marginal: medium development, wooded wetland, low-density development. A forced landing there is survivable but not ideal. A delayed response means a forced landing in marginal terrain, not a return to the airport.
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 morning conditions at KSRQ. 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 and no alternate air system. Carburetor heat is the only tool.
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.
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 fuel selector is LEFT / RIGHT — there is NO BOTH position.
Unlike some Cessnas, the Piper Cherokee 180 has a LEFT / RIGHT fuel selector with no BOTH position. The pilot must actively switch tanks to balance fuel and avoid starvation. Running a selected tank dry — or taking off on a near-empty tank — is the signature fuel starvation trap in this airplane. Know which tank you are on at all times. Develop a habit of switching tanks every 15–20 minutes of flight. If the left tank is full and the right tank is low, do not take off on the right tank — you will run it dry within minutes.
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 350 ft AGL is waiting too long.
Off Runway 04 at KSRQ, the off-field environment is marginal — not ideal for a forced landing.
The off-field environment off Runway 04's climb-out (heading 038°) is medium development, wooded wetland, and low-density development. A forced landing there is survivable but not ideal — trees, power lines, and scattered buildings are hazards. A forced landing in marginal terrain is better than a stall/spin trying to stretch a glide to the runway, but it is not the outcome you want. Early carb heat application and a quick return to the airport is the better path.
