Total Power Loss on the Runway 36 Climb
Engine failure at 300 feet AGL over open water — a controlled ditching is the only option
The scenario
Departing Tampa Executive Airport (KVDF), Tampa, FL — Runway 36, climbing out on a northbound heading. Field elevation 22 ft MSL. You are a Private pilot with 180 hours total time, current and proficient. This is a local flight in a Cessna 172M — the lower-powered 150 hp variant, not the 180 hp 172N. Fuel is full, weight is within limits, and the airplane was airworthy at preflight.
It is a clear, calm morning. OAT 24°C, altimeter 29.92, light winds from the south. Visibility 10 SM. The runway is dry. You completed a thorough preflight, ran the engine on the ground (it ran smoothly), and cleared the engine with a power check. Nothing was written up. The fuel selector is set to BOTH, the mixture is appropriate for the field elevation, and the engine instruments are in the green.
You line up on Runway 36, advance the throttle to full power, and begin the takeoff roll. Rotation speed (Vr) is 55 KIAS. At 55 KIAS you rotate and the nose comes up. The airplane lifts off at roughly 60 KIAS and begins to climb. You are now 100 feet AGL, heading 360° (north), climbing at 70 KIAS (slightly above Vy of 78 KIAS — a normal initial climb profile). The runway is behind you.
At 300 feet AGL, the engine suddenly loses all power. The tachometer drops to zero. The propeller is still turning (windmilling), but there is no engine power. The airplane is climbing at 70 KIAS in still air — you have roughly 2 minutes of glide time before touchdown, but you are heading north (360°) over open water, wooded wetland, and medium development. The airport is behind you. You have seconds to decide what to do.
Aircraft: Cessna 172M, solo, full fuel, within limits. Lycoming O-320-E2D, 150 hp, carbureted, fixed-pitch prop, fixed gear, fuel selector BOTH. Best glide speed is 65 KIAS. Vacuum-driven steam panel (attitude + heading indicator). No glass, no autopilot, no redundancy.
Pilot: you — Private pilot, 180 hours, current. You have never experienced a total power loss in flight. You have never ditched an airplane. You have never been in an emergency at 300 feet AGL. This is the moment.

The decision
Before we enter the decision tree — what do you know about total engine power loss at low altitude? (Pick all that apply; this records your baseline.)
What the record shows
What the NTSB files show
NTSB ERA15LA091 (2014): A Cessna 172M experienced total loss of engine power during cruise flight at 10,500 feet over the Atlantic Ocean, approximately 5 miles from the nearest land. The pilot ditched the aircraft in the ocean. The probable cause was total loss of engine power for reasons that could not be determined — examination of the engine revealed no anomalies that would have precluded normal operation. The engine failure was inexplicable, but the ditching was controlled and survivable.
NTSB ERA11LA429 (2011): A Cessna 172M experienced partial engine power loss during takeoff at Lake Okeechobee, Florida. The pilot initially attempted to return to the airport but recognized the altitude loss in the turn was excessive. The pilot committed to a controlled ditching in the lake. The probable cause was separation of the No. 3 cylinder exhaust valve head from the stem, with a contributing factor of engine operation beyond the manufacturer's recommended time between overhauls. The pilot's decision to commit to ditching rather than attempt a marginal return-to-airport saved his life.
NTSB ANC08LA007 (2007): A float-equipped Cessna 172M nosed over during a water landing on Rangeley Lake when the pilot's attention was diverted by military helicopters operating in close proximity. The pilot failed to maintain aircraft control during the landing flare/touchdown. The accident resulted from the pilot's failure to maintain control during the water landing, with diverted attention as a contributing factor. Even in a controlled ditching scenario, maintaining focus on the landing is critical.
NTSB IAD02LA003 (2001): A Cessna 172M on a fish spotting flight over the Chesapeake Bay near White Stone, Virginia lost engine power at 2,500 feet. The pilot ditched the aircraft in the water. The probable cause was loss of engine power for undetermined reasons. The pilot survived the ditching.
The regional precedents (FTW85LA199, NYC03LA109, BFO91LA069, ANC13LA048) all involved low-altitude engine failures over water. The consistent thread: pilots who committed to a controlled ditching and executed proper water-landing procedures (best glide speed, full flaps for slowest touchdown speed, doors unlatched, master off before impact) survived. Pilots who attempted marginal glides back to the runway or stretched approaches at high descent rates did not.
Tampa Executive Airport (KVDF) is a non-towered field with two runways. Runway 36's departure environment is open water and wooded wetland to the north — a ditching environment. This scenario is localized to KVDF to make the off-field reality consequential: a total engine power loss on the Runway 36 departure at low altitude is a ditching, not a field landing. The real accidents cited above occurred at other airports and in other aircraft — NOT at KVDF. But the geographic principle is the same: know your off-field environment before you take off.
Key lesson — Total engine power loss at 300 feet AGL over water is survivable if you act decisively. Establish best glide speed (65 KIAS) immediately. Assess whether return-to-airport is feasible — at 300 feet AGL, a 180° turn back to the airport requires altitude you may not have. If return-to-airport is not feasible, commit to a controlled ditching: maintain best glide, use full flaps to minimize touchdown speed, keep doors unlatched, turn the master off just before water contact. Impact energy rises with the square of touchdown speed — the slowest possible touchdown speed is the single most important factor in ditching survival. A controlled ditching at 65 KIAS with full flaps is survivable. An uncontrolled impact at high airspeed is not.
Debrief — teaching points
Total engine power loss cannot be recovered at 300 feet AGL — commit to ditching immediately.
When the engine quits at low altitude, restart attempts are a luxury you do not have. At 300 feet AGL, you have roughly 2 minutes of glide time. Spending 30 seconds on restart attempts (checking fuel selector, trying magnetos, attempting a restart) costs you altitude and delays your decision to either return-to-airport or ditch. The correct response to total power loss at low altitude is: establish best glide speed (65 KIAS) immediately, assess return-to-airport feasibility, and if not feasible, commit to ditching. Do not attempt restarts at low altitude.
At 300 feet AGL over water, a 180° turn back to the airport is marginal at best.
A shallow turn at 65 KIAS and 250 feet AGL requires roughly 30–40 seconds to complete a 180° heading change. During that turn, you will lose 100–150 feet of altitude. You will roll out at 100–150 feet AGL. If the airport is more than 0.5 nm away, you may not make it. If the airport is closer and the runway is available, the return is feasible but tight. Know your field geometry before you take off: from Runway 36 at KVDF, the airport is 0.5–0.8 nm behind you at 300 feet AGL. A return is marginal but possible if you act immediately.
Establish best glide speed (65 KIAS) immediately — this is the single most important action.
Best glide speed for the C172M is 65 KIAS. This speed maximizes glide distance and gives you the most time and distance to manage the emergency. At 300 feet AGL, every second counts. Establish 65 KIAS by lowering the nose and trimming the airplane. Do not attempt to maintain altitude or climb — you are powerless. Lower the nose, establish 65 KIAS, and assess your options.
Off Runway 36 at KVDF, the departure environment is open water and wooded wetland — a ditching environment.
The off-field environment off Runway 36's departure end (heading 360°) is open water, wooded wetland, and medium development. There is no alternate landing surface. An engine failure on the Runway 36 departure at low altitude is a ditching, not a field landing. Know your off-field environment before you take off. If the weather is marginal, if the engine is running rough, or if you have any doubt about the airplane's airworthiness, use Runway 05 or 18 instead — both have better off-field options (pasture/hay, low-density development).
In a ditching, full flaps minimize touchdown speed — impact energy rises with the square of speed.
The slowest possible touchdown speed is the single most important factor in ditching survival. Full flaps (40°) in the C172M reduce touchdown speed to roughly 50 KIAS (near Vs0 stall speed in landing configuration). Impact energy rises with the square of touchdown speed — reducing touchdown speed from 65 KIAS to 50 KIAS reduces impact energy by roughly 40%. Use full flaps in a ditching. The slight increase in descent rate is acceptable; the reduction in touchdown speed is critical.
Doors unlatched and master off just before water contact are non-negotiable.
Unlatched doors allow you to exit the airplane quickly after water contact. A latched door can jam and trap you inside. Turn the master switch off just before water contact to prevent electrical fire and fuel flow after impact. These two actions — unlatched doors and master off — are the difference between a survivable ditching and a fatal one. Brief them before you take off; execute them in the moment.
