The decision

Before we get into the decision tree — what do you already know about engine failures in the DA40? (Pick all that apply; this records your baseline.)

What the record shows

What the NTSB files show

Key lesson — In the DA40, an engine failure at low altitude is a forced landing, not a recovery scenario. Establish best glide at 73 KIAS immediately. Diagnose briefly (fuel starvation vs. mechanical). Pick the best available landing site in the off-field environment. Execute a controlled forced landing at the slowest possible speed. The off-field environment at KSRQ determines the outcome: off Runway 04, marginal but survivable; off Runway 22, ditching. Know the environment before you depart.

Debrief — teaching points

The DA40's fuel selector is LEFT / RIGHT — there is no BOTH position. Fuel starvation is a real risk.

Unlike Cessnas (which have a BOTH position), the DA40 requires active fuel selector management. If the selected tank is empty or has a fuel selector issue, the engine will lose power. In an emergency, switch to the other tank immediately. If the power loss persists after switching, it is a mechanical failure, not fuel starvation. The DA40 POH recommends switching tanks every 30 minutes during cruise to balance fuel consumption. A pilot who forgets to switch tanks or selects an empty tank will experience a power loss that looks identical to a mechanical failure — until the switch to the other tank restores power.

The DA40's constant-speed prop requires active RPM management. Incorrect prop control can reduce power.

The DA40's Lycoming IO-360-M1A has a constant-speed propeller. The prop control lever adjusts RPM; the throttle adjusts manifold pressure. If the prop control is not set correctly for the phase of flight (climb, cruise, descent), the engine may not develop full power. During climb, the prop control should be in the full-forward (high-RPM) position. If the prop is not set correctly, the engine will run rough or lose power. In an emergency, cycle the prop control to ensure it is in the correct position — but do not spend more than 5 seconds on this diagnosis. If the power loss persists, it is a mechanical failure.

Best glide in the DA40 is 73 KIAS at gross weight. Establish it immediately if power is lost.

Best glide speed maximizes glide distance and gives the most time and distance to manage the emergency. At 300 ft AGL with a power loss, establishing 73 KIAS immediately is the first priority after leveling the wings. The DA40 is a slippery airplane — it floats in a descent. If you try to stretch the glide by reducing power or climbing, the airspeed will decay and you risk a stall. Maintain 73 KIAS and focus on the landing site selection.

The DA40's slippery airframe requires active energy management on approach. Use forward slip or shallow bank to increase descent rate.

The DA40 is a composite, low-drag airplane. It floats in a descent and is difficult to slow down. If you are too high on approach to a forced landing, you cannot simply reduce power — the airplane will float. Use a forward slip (aileron and rudder in opposite directions to increase drag without increasing airspeed) or a shallow bank to increase descent rate. Maintain 73 KIAS throughout the descent. The goal is to touch down at the slowest possible speed — impact energy rises with the square of touchdown speed.

At KSRQ, the off-field environment determines the outcome. Off Runway 04, marginal but survivable; off Runway 22, ditching.

Off Runway 04's departure end (heading 038°), the off-field environment is marginal: medium development, wooded wetland, low-density development. A forced landing is survivable if you pick the best available site (clearing, open field, or road). Off Runway 22's departure end (heading 218°), the off-field environment is ditching: open water and low-density development. An engine failure on the Runway 22 departure is a water landing, not a field landing. Know the environment before you depart. If you depart Runway 22 and lose the engine at low altitude, your only option is a controlled ditching — doors unlatched, master off before impact, flaps for slowest possible touchdown speed.

Do not try to turn back to the runway at 300 ft AGL with a failing engine. Establish best glide and pick the best landing site ahead.

The 'impossible turn' is a real risk in low-altitude engine failures. At 300 ft AGL with a failing engine, a 180° turn back to the departure runway requires altitude and control authority you may not have. The safer decision is to establish best glide, pick the best available landing site in the off-field environment ahead, and execute a controlled forced landing. The NTSB data shows that pilots who try to turn back to the runway at low altitude with a failing engine often stall or spin. Pilots who focus on the best available landing site ahead survive.
