Power Loss on Climb — Tampa Executive
Engine failure at 300 ft AGL over Tampa Executive Airport: off-field options are real, and the decision window is measured in seconds
The scenario
Departing Tampa Executive Airport (KVDF), Tampa, FL — Runway 05, climbing out on a 042° heading. Elevation 22 ft MSL. It is a clear, calm morning: OAT 18°C, winds calm, altimeter 30.01. Visibility 10 SM. A routine local flight in a Diamond DA40, solo, full fuel, within limits.
You are 300 ft AGL, climbing at 66 KIAS (Vy), heading 042°, when the engine begins to lose power. The manifold pressure is dropping, the tachometer is unwinding, and the airplane is no longer climbing — it is maintaining altitude at best. The runway is behind you. Ahead and to your left (north-northeast) is wooded wetland and medium development. To your right (east-southeast) is pasture, hay fields, and scattered development. Behind you and to the right is open water.
Aircraft: Diamond DA40, fuel-injected Lycoming IO-360-M1A, constant-speed prop, fixed gear, G1000 glass panel. Fuel selector is set to LEFT (you switched to LEFT after takeoff per procedure). Nothing was written up; the airplane was airworthy at departure. The last 100-hour inspection was completed 15 hours ago.
Pilot: you — a Commercial pilot, current, roughly 800 hours total. You have 120 hours in the DA40. You are familiar with this airport and the surrounding area. You did not notice any anomalies during the run-up or initial climb.

The decision
Before we get into the decision tree — what do you already know about engine failure in the DA40 and off-field landing options? (Pick all that apply; this records your baseline.)
What the record shows
What the NTSB files show
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 two clamps securing the flexible coupling from the intercooler to the induction inlet during a 100-hour inspection performed 15 hours before the accident. The loose coupling allowed induction air to leak, reducing intake air pressure and causing partial power loss.
NTSB ERA23LA285 (2023): A Diamond DA40 NG experienced partial engine power loss during climb due to fatigue failure of the diesel engine's turbocharger housing. The pilot made a forced landing to a school field. The probable cause was a fatigue failure of the turbocharger housing, which resulted in a partial loss of engine power and reduced intake air.
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 common thread across all three accidents: engine failure in the DA40 is often partial, not total — the airplane is still flying, but power is degraded. The pilot's response is critical. Establishing best glide speed (73 KIAS) immediately and committing to a landing site within the first 20–30 seconds of power loss determines the outcome. Delaying the decision, trying to climb or turn back without establishing best glide, or attempting to diagnose the problem while descending through low altitude all cost altitude and options.
At KVDF, the off-field environment is specific: off Runway 05's climb-out (heading 042°), the terrain is wooded wetland and medium development — rough, but landable. Off Runway 05's right side (east-southeast), the terrain is pasture and hay fields — better. Off Runway 36's climb-out (heading 360°), the terrain includes open water — a ditching, not a field landing. The real accidents cited above occurred at other airports and in other aircraft — NOT at Tampa Executive Airport. KVDF has its own accident history (see field dominant patterns), but these specific events happened elsewhere. The scenario is localized to KVDF to make the off-field environment real and consequential for you as a student here.
The consistent lesson: in an engine failure at low altitude, the first 30 seconds are decisive. Establish best glide speed, commit to a landing site, and fly the airplane to that site. Do not delay, do not try to climb, do not attempt a complex turn back without best glide speed. The DA40 is a slippery airplane — it floats and glides well — but only if you manage energy correctly. Best glide is 73 KIAS. Know it. Fly it.
Key lesson — Engine failure in the DA40 at low altitude is survivable if you establish best glide speed (73 KIAS) immediately and commit to a landing site within the first 30 seconds. Delaying the decision or attempting to turn back without best glide speed costs altitude and options. Off Runway 05 at KVDF, the off-field environment is wooded wetland (ahead) or pasture (to the right) — both are landable. Off Runway 36, open water is a ditching. Know your off-field options before you depart.
Debrief — teaching points
Best glide speed in the DA40 is 73 KIAS — establish it immediately in any power-loss scenario.
The DA40 is a slippery, efficient airplane. Best glide speed is 73 KIAS at gross weight. This speed maximizes glide distance and gives you the most time and distance to manage the emergency. At 300 ft AGL with a failing engine, establishing 73 KIAS in the first 10 seconds is the single most important action. Every second you spend at a higher or lower airspeed costs you altitude and distance. Drill this: power loss = lower the nose to 73 KIAS immediately.
The DA40 fuel selector is LEFT / RIGHT — there is no BOTH position. Tank starvation is a real risk.
Unlike some Cessnas, the DA40 has no BOTH position on the fuel selector. You must actively manage LEFT and RIGHT tanks. A pilot who selects an empty tank will experience sudden power loss. Before every flight, verify fuel quantity in both tanks and plan your tank-switching protocol. In this scenario, the fuel selector was on LEFT and the LEFT tank had adequate fuel — so the power loss was mechanical, not fuel starvation. But if the LEFT tank had been empty, the diagnosis would have been immediate: switch to RIGHT. Always know your fuel status.
Engine failure at low altitude is a forced landing — not a return to the airport.
At 300 ft AGL, you do not have the altitude to troubleshoot, climb, or execute a complex return to the airport. You have the altitude to glide to the nearest suitable landing site — and that is your only option. The decision is not 'can I make the airport?' — it is 'where can I land safely right now?' Off Runway 05 at KVDF, that means the wooded wetland ahead, the pasture to the right, or (if you have enough altitude) a turn back to Runway 23. Every second you spend trying to climb or diagnose costs altitude. Commit to a landing site and fly to it.
Off-field landing sites at KVDF are specific and real — know them before you depart.
Off Runway 05's climb-out (heading 042°): wooded wetland and medium development — rough, but landable. Off Runway 05's right side (east-southeast): pasture and hay fields — better. Off Runway 36's climb-out (heading 360°): open water — a ditching. Off Runway 23's climb-out (heading 222°): pasture, hay, and medium development — good. Off Runway 18's climb-out (heading 180°): low-density development and wooded wetland — marginal. These are not hypothetical; they are the real USGS NLCD ground cover off each runway end. Know the terrain before you depart. If you depart Runway 05, you know the wooded wetland is ahead and the pasture is to the right. That knowledge, combined with best glide speed, determines your survival.
The constant-speed prop in the DA40 requires active management — a loose induction coupling can cause partial power loss.
The DA40's constant-speed prop is efficient but requires prop control (RPM management). The induction system includes a flexible coupling from the intercooler to the induction inlet. If the clamps securing this coupling are not properly tightened (as in NTSB ERA19LA272), the coupling can loosen, induction air can leak, and engine power is lost. This is a post-maintenance risk. After any 100-hour or major inspection, verify that all induction system clamps are tight and secure. A loose coupling is a subtle failure — the engine runs, but power is degraded — and it can happen at the worst possible time: on takeoff or climb.
Turbocharger housing fatigue is a long-term risk in turbocharged DA40s — monitor engine parameters closely.
The DA40 NG uses a turbocharged diesel engine. The turbocharger housing can develop fatigue cracks over time, especially if the engine is operated at high power settings or if maintenance is deferred. A crack in the turbocharger housing reduces intake air pressure and causes partial power loss (as in NTSB ERA23LA285). Monitor manifold pressure, engine temperature, and fuel flow closely during climb. If you notice an unexplained drop in manifold pressure or a loss of climb performance, suspect a turbocharger issue and consider returning to the airport for inspection. Do not ignore subtle power losses.
In a forced landing, flaps are your friend — they slow the airplane and reduce landing distance.
The DA40's maximum flap extension speed is 91 KIAS (landing position). At best glide speed of 73 KIAS, you are well below the flap limit. Adding flaps as you descend into the landing site slows the airplane and reduces landing distance. Impact energy rises with the square of touchdown speed — the slowest possible touchdown speed matters most. In a forced landing to a rough or short field, add flaps to slow the airplane. In a forced landing to a long runway, you can leave flaps up if you prefer more control authority. But in a rough field, flaps are your friend.
