Engine Loss Over Clearwater
Total power loss in a fuel-injected trainer — off-field options are dense development on all sides
The scenario
Departing Clearwater Air Park (KCLW), Clearwater, FL — Runway 16, climbing out on a 155° heading. Elevation 71 ft MSL. It is a clear, calm morning; OAT 22°C, altimeter 30.01, light winds from the south. Visibility 10 SM. Classic Florida VFR — the kind of day that breeds complacency.
You are a Private pilot with roughly 250 hours total, 40 hours in the Diamond DA20-C1. This is a familiar airplane at a familiar field. You are flying solo, full fuel (18 gallons usable), within weight and balance. The airplane was airworthy at preflight; nothing was written up. You completed a standard preflight and run-up. Engine instruments all green.
Aircraft: Diamond DA20-C1. Continental IO-240-B, fuel-injected (no carburetor heat). Fixed gear, fixed-pitch prop, steam panel. Single fuel tank with ON/OFF selector. Best glide 73 KIAS. Vne 164 KIAS, Va 106 KIAS, Vy 75 KIAS.
You are climbing through 800 ft AGL at 75 KIAS (Vy), heading 155°, when the engine begins to lose power. The tachometer is unwinding. The engine is not running rough — it is simply producing less power. You are still over the airport environment, but you are climbing away from the field. The off-field terrain ahead (heading 155°) is dense development — low-rise residential, some medium-density commercial. There is no open field, no water, no obvious forced-landing site. Just buildings and streets.
Pilot: you — a Private pilot, current, 250 hours total, 40 hours DA20. You did a preflight fuel check — the tank appeared full. You did not calculate fuel burn or time-to-climb. You did not brief an alternate or a forced-landing site. You assumed the fuel was adequate for a local flight. You did not consult the POH fuel planning table. You did not review the engine failure checklist before takeoff.

The decision
Before we get into the decision tree — what do you already know about engine failure in the DA20-C1? (Pick all that apply; this records your baseline.)
What the record shows
What the NTSB files show
NTSB WPR23LA324 (2023): A Diamond DA20 on an instructional flight lost total engine power during a simulated engine failure when the student advanced the throttle with the mixture leaned. The pilot made a forced landing off-airport. The probable cause was the flight instructor's failure to follow the engine failure checklist and the student's improper fuel management. The accident was survivable but resulted in substantial damage.
NTSB GAA19CA569 (2019): A Diamond DA20 experienced total engine power loss on approach due to fuel exhaustion after four flights in one day. The pilot made a forced landing on a service road between buildings and struck a tree. The probable cause was the pilot's improper preflight fuel planning — the pilot did not calculate fuel burn or time-to-climb and did not consult the POH fuel planning table. The accident was survivable.
NTSB ERA19LA074 (2018): A Diamond DA20 on a post-maintenance test flight experienced partial engine power loss during climb due to debris obstructing the metering plug orifice in the throttle and metering unit. The pilot made a forced landing to a clearing, impacting trees. The probable cause was post-maintenance debris left in the fuel system.
NTSB ERA19LA029 (2018): A Diamond DA20 experienced partial engine power loss during cruise flight and made a forced landing in a field. The accident resulted from multiple discrepancies in the engine's ignition system, including worn magnetos and damaged ignition harnesses. The pilot survived.
NTSB CEN16LA018 (2015): A Diamond DA20-C1 on a personal night flight made a forced landing in a field after total engine failure due to fuel exhaustion. The probable cause was the pilot's operation of the aircraft without the owner's permission and inadequate preflight planning — the pilot did not calculate fuel burn or brief an alternate landing site.
The real accidents cited above occurred at other airports and in other aircraft types — NOT at Clearwater Air Park. KCLW has its own accident history (see field dominant patterns: forced landing 22.2%, loss of control 18.5%, gear-up landing 18.5%), but these specific NTSB cases happened elsewhere. The scenario is localized to KCLW to make the off-field environment real and consequential for you as a student here.
The consistent thread across all these events: engine power loss in the DA20 is often survivable if the pilot establishes best glide immediately (73 KIAS), diagnoses the cause (fuel exhaustion, magneto failure, debris, fuel contamination), and either restores power or returns to the departure field. The failure is always a delay — trying to climb out of the problem, not establishing best glide, or not turning back to the field when altitude permits.
Key lesson — In the DA20-C1, engine power loss is often partial and survivable if you establish best glide immediately (73 KIAS), diagnose the cause (fuel exhaustion, magneto failure, debris, fuel contamination), and return to the departure field if altitude permits. Off Runway 16 at KCLW (heading 155°), the off-field environment is dense residential development — no open field, no water, no obvious forced-landing site. The airport is your best option. Establish best glide, diagnose, and turn back to KCLW if you have the altitude. Preflight fuel planning and a pre-takeoff engine failure checklist review are non-negotiable.
Debrief — teaching points
Establish best glide immediately — 73 KIAS in the DA20.
The moment you recognize engine power loss, lower the nose to 73 KIAS best glide. This is the speed that maximizes glide distance and gives you the most time and distance to diagnose the problem and plan a landing. Do not try to climb out of the problem. Do not try to restore power by advancing the throttle. Establish best glide first; diagnose second. At 800 ft AGL, the difference between establishing best glide immediately and delaying is the difference between making it back to the field and landing in dense development.
The DA20 has a single fuel tank with ON/OFF selector — fuel risk is quantity planning, not mis-selection.
Unlike a Piper or Cessna with left/right tank selection, the DA20 has one fuel tank. You cannot cause fuel starvation by selecting the wrong tank. But you can cause fuel exhaustion by not planning fuel burn correctly. The POH fuel planning table shows roughly 5.5–6.5 gallons per hour at cruise. A preflight fuel check (visual or dip-stick) is not the same as a fuel-burn calculation. If you have 18 gallons usable and burn 6 GPH, you have 3 hours of fuel — not 'full fuel means I can fly as long as I want.' Calculate fuel burn before every flight.
The DA20's Continental IO-240-B is fuel-injected — there is NO carburetor heat.
The DA20 does not have a carburetor or carburetor heat system. Carb ice is not a failure mode. Engine power loss in the DA20 is caused by fuel exhaustion, fuel contamination, magneto failure, debris in the throttle metering unit, or ignition system discrepancies. Diagnose the power loss by checking the fuel selector (ON/OFF), checking the fuel pump (ON/OFF), and cycling the magneto switch (LEFT, RIGHT, BOTH) to identify a partial magneto failure. Do not look for carb heat — it does not exist.
A magneto check during run-up is critical — one mag out is a partial power loss.
The DA20's dual-magneto ignition system can fail partially (one mag degraded or out) or totally (both mags out). During run-up, you should perform a mag check: run the engine at 1,700 RPM, select LEFT mag and note the RPM drop (should be no more than 150 RPM), select RIGHT mag and note the RPM drop (should be no more than 150 RPM), and confirm that the differential between the two mags is no more than 50 RPM. If the differential is large or one mag is out, do not fly. A magneto failure in flight will show as a partial power loss and a rough engine. Cycle the mag switch to identify which mag is out.
Off Runway 16 at KCLW, the off-field environment is dense development — the airport is your best option.
The off-field terrain off Runway 16 (heading 155°) at KCLW is dense residential development — low-rise homes, streets, some trees. There is no open field, no water, no obvious forced-landing site. If you lose power on the Runway 16 departure, your best option is to turn back to KCLW and land on Runway 16 or 34. A street landing or parking lot landing in the development is possible but riskier. Know the off-field environment before you depart. If you lose power and have the altitude, turn back to the field.
Preflight fuel planning and a pre-takeoff engine failure checklist review are non-negotiable.
Before every flight, calculate fuel burn using the POH table and confirm you have adequate fuel for the flight plus reserves. Brief an alternate landing site in case of engine failure. Review the engine failure checklist before takeoff — know what to check (fuel selector, fuel pump, magneto switch) and in what order. A visual fuel check ('the tank looks full') is not the same as a fuel-burn calculation. The NTSB accidents cited in this scenario were caused by pilots who skipped these steps. Do not be that pilot.
