Power Loss Over Pinellas Park
Engine failure on initial climb from Runway 22 — congested development ahead, no good forced-landing site, and a constant-speed prop that demands energy management
The scenario
Departing St. Petersburg Clearwater International Airport (KPIE), Pinellas Park, FL — Runway 22, initial climb on a 220° heading. Field elevation 11 ft MSL. You are a commercial pilot with roughly 800 hours total, 120 in the DA40. This is a local flight in your own aircraft.
Conditions: VFR, clear skies, light winds from the north (010° at 4 kt). OAT 24°C, altimeter 30.02. Visibility 10+ SM. A perfect Florida morning. You are within weight and balance limits, fuel is full (both tanks), and the airplane was airworthy at the last inspection — a 100-hour performed 22 hours ago by your local shop.
You line up on Runway 22, apply full power, and rotate at 54 KIAS (Vr). The airplane lifts off cleanly. You are climbing at 66 KIAS (Vy, best rate of climb) through 200 ft AGL when the engine begins to lose power. The manifold pressure gauge is unwinding. The tachometer is dropping. The constant-speed prop is not responding — RPM is falling despite the prop control being full forward.
Runway 22's climb-out environment (heading 220°) is dense development — residential neighborhoods, schools, small commercial buildings. There is no open field, no park, no water. The terrain is built-up and congested. You have roughly 30 seconds of useful decision time before altitude becomes critical.
Aircraft: Diamond DA40, fuel-injected Lycoming IO-360-M1A, constant-speed prop, fixed gear, G1000 glass panel. The airplane is slippery when clean — energy management on approach matters. Best glide is 73 KIAS. Fuel selector is LEFT / RIGHT (no BOTH position) — a mis-selected or empty tank is a starvation risk.
Pilot: you — a commercial pilot, current, 800 hours total, 120 in type. You completed a thorough preflight, ran the engine-start and systems checks, and confirmed fuel selector on the RIGHT tank (which was full). The 100-hour inspection was completed 22 hours ago. Nothing was written up.

The decision
Before we get into the decision tree — what do you already know about engine failure on initial climb in the DA40? (Pick all that apply; this records your baseline.)
What the record shows
What the NTSB files show
NTSB ERA23LA285 (2023): A Diamond DA40 NG experienced partial engine power loss during climb due to fatigue failure of the turbocharger housing. The pilot made a forced landing to a school field. The probable cause was the fatigue failure of the turbocharger housing, which reduced intake air and caused the power loss. The pilot's immediate recognition of the power loss and commitment to the school field saved the flight.
NTSB ERA19LA272 (2019): A Diamond DA40 on a personal local flight experienced a partial loss of engine power on takeoff at 300 feet AGL. The pilot made a forced landing to a soybean field. The probable cause was a mechanic's failure to properly tighten the clamps securing the flexible induction coupling during a 100-hour inspection performed 15 hours before the accident. The coupling failed, allowing air to bypass the engine, and reducing power. The pilot's quick decision to land in the available field prevented a worse outcome.
NTSB ERA18LA241 (2018): A Diamond DA40 experienced total loss of engine power while on downwind approach to Maury County Airport. The pilot performed a forced landing to a field approximately 1 mile short of the runway threshold. The loss of engine power could not be determined based on postaccident examination, which revealed no evidence of mechanical malfunctions or failures. The pilot's decision to land in the available field, rather than attempt to stretch the glide to the runway, was the correct call.
NTSB SEA92LA095 (1992): A Ryan ST-3KR lost engine power during initial climb after takeoff due to fatigue failure of the crankshaft counterweight cap screws. The pilot made a forced landing on a residential street where the aircraft impacted an embankment, ground looped, and was destroyed by post-impact fire. The probable cause was the fatigue failure of the crankshaft, with a contributing factor of lack of suitable terrain for forced landing. The pilot's delay in committing to a landing area and attempt to maneuver unpredictably led to the uncontrolled impact.
NTSB MIA91LA128 (1991, FATAL): A Sonerai-II homebuilt aircraft experienced total engine failure shortly after takeoff. The pilot made a forced landing in an alley where it touched down hard, bounced, and struck a telephone pole. The probable cause was the pilot's improper adjustment of the carburetor mixture control. Witnesses noted reduced power on takeoff. The pilot's delay in committing to a landing area and attempt to bounce and stretch the glide led to the fatal impact.
NTSB CHI83LA094 (1983): A Piper PA-22-135 lost engine power during takeoff climb at 150 feet AGL and struck 60-foot trees near the runway end while attempting to return to the airport. The probable cause was a fractured mixture control cable that caused total engine power loss. The pilot's attempt to turn back to the runway at low altitude, rather than committing to the best available landing area ahead, led to the uncontrolled impact.
NTSB CHI92DER01 (1992): A Goehring Quickie lost engine power during initial climb after a touch-and-go landing and made a forced landing in a residential area after descending through trees and a house. The probable cause was attributed to carburetor ice, with lack of suitable terrain for forced landing as a contributing factor. The pilot's delay in committing to a landing area and attempt to maneuver around obstacles led to the descent through trees and residential structures.
The real accidents cited above occurred at other airports and in other aircraft — NOT at KPIE. KPIE's dominant accident pattern includes LOSS_OF_CONTROL_INFLIGHT (21.2%), LOSS_OF_CONTROL_GROUND (15.2%), STALL_SPIN (12.1%), GEAR_UP_LANDING (9.1%), and OBSTACLE_ON_TAKEOFF_LANDING (9.1%). The scenario is localized to KPIE to make the off-field environment real and consequential for you as a pilot here.
The consistent thread across all these events: engine failure on initial climb at low altitude over congested development is survivable if the pilot commits immediately to the best available landing area ahead. The failures are always a delay — attempting to troubleshoot, attempting to return to the runway, attempting to maneuver around obstacles, or attempting to stretch the glide to a better landing area. At 200 ft AGL with a failing engine, the decision window is measured in seconds, not minutes. Commit to the best available landing area immediately.
Key lesson — Engine failure on initial climb at low altitude over congested development (like Runway 22's climb-out at KPIE) is survivable if you commit immediately to the best available landing area ahead. The critical decision is made in the first 10 seconds: establish best glide speed (73 KIAS), scan for the best available landing area (parking lot, school field, wide street), and commit to it. Do not delay to troubleshoot, do not attempt to return to the runway, do not attempt to maneuver around obstacles. The best available landing area is the one directly ahead of you — commit to it and land. The DA40's constant-speed prop and slippery airframe demand energy management on approach: use flaps at Vfe (91 KIAS) to control descent rate and landing distance. Delay is the killer.
Debrief — teaching points
Engine failure on initial climb at low altitude is a forced-landing emergency — not a troubleshooting exercise.
At 200 ft AGL with a failing engine, you have roughly 30 seconds of decision time and roughly 1.5 nm of glide distance. Troubleshooting — checking the fuel selector, cycling the prop control, adjusting the mixture — consumes altitude and time you do not have. The first action is to establish best glide speed (73 KIAS), trim for hands-off flight, and scan for the best available landing area. Troubleshooting can wait until you are on the ground or until you have climbed to a safe altitude where you have time to diagnose.
Commit to the best available landing area immediately — do not delay, do not maneuver, do not stretch the glide.
At 200 ft AGL over congested development, the best available landing area is the one directly ahead of you — a parking lot, school field, or wide street. Commit to it immediately. Do not attempt to return to the runway (the turn consumes altitude), do not attempt to maneuver around obstacles (you lose altitude and lose sight of the landing area), do not attempt to stretch the glide to reach a better landing area farther away (you trade speed for altitude, which reduces glide distance). The best landing area is the one you can reach with the altitude you have. Commit to it and land.
The DA40's constant-speed prop is a critical system — understand its failure modes.
The DA40's constant-speed prop is a marvel of engineering, but it is also a single point of failure. If the prop control fails or the engine loses power, the prop will not respond to the control input — RPM will drop even if you push the prop control full forward. In the scenario, the prop is not responding because the engine is losing power, not because the prop is mis-set. Understand this distinction: a prop control that does not respond to input is a symptom of engine failure, not a prop malfunction. Do not waste time troubleshooting the prop — establish best glide speed and commit to a landing area.
The DA40 fuel selector is LEFT / RIGHT only — a mis-selected tank is a starvation risk.
Unlike some aircraft with a BOTH position, the DA40 fuel selector is LEFT / RIGHT only. The pilot must actively manage the fuel selector during flight. A mis-selected tank (selecting an empty tank, or selecting the wrong tank during a crossfeed) will cause fuel starvation and engine failure. In the scenario, you confirmed the fuel selector was on the RIGHT tank and the fuel quantity was correct — so fuel starvation is not the cause. But understand this risk: if you had not confirmed the fuel selector during the preflight and engine-start checks, a mis-selected tank could have caused the power loss. Always confirm the fuel selector is on the correct tank before takeoff and monitor fuel quantity during flight.
Post-maintenance engine failures are often due to mechanic error — loose clamps, improper assembly, or contamination.
NTSB ERA19LA272 is a stark example: a mechanic failed to properly tighten the clamps securing the flexible induction coupling during a 100-hour inspection. The coupling failed 15 hours later, allowing air to bypass the engine and reducing power. In the scenario, the 100-hour inspection was completed 22 hours ago — well within the window for a post-maintenance failure. If the engine failure is due to a mechanic's error, the investigation will reveal it. But the pilot's job is to survive the emergency first, investigate second. Establish best glide speed, commit to a landing area, and land safely. The investigation happens after.
Runway 22's climb-out environment is dense development — there is no open field or water for a forced landing.
Off Runway 22's climb-out (heading 220°), the off-field environment is dense development — residential neighborhoods, schools, small commercial buildings. There is no open field, no park, no water. A forced landing off Runway 22 will be on a parking lot, school field, street, or other developed area. This is the geographic reality of KPIE. Know this before you line up on Runway 22. If you are uncomfortable with a forced landing in a congested area, use Runway 4 or Runway 36 instead — both have better off-field options (water for Runway 4 and Runway 36, which is a ditching; open developed areas for Runway 4).
Energy management on approach matters in the DA40 — use flaps to control descent rate and landing distance.
The DA40 is a slippery airplane — it floats on landing even at best glide speed. In a forced landing on a parking lot or street, flaps are the tool to control descent rate and landing distance. Add flaps at Vfe (91 KIAS) to increase descent rate and slow the airplane. Do not use a forward slip, which reduces your ability to judge your landing point and manage the approach. Do not keep the airplane clean and float down the pavement — you will overshoot the landing area and strike obstacles. Flaps are your friend in a forced landing on pavement.
