Vmc, Vsse, Vyse (blue line), and accelerate-stop/go distances are critical for multi-engine emergency decisions and are not included here — all must come from the specific aircraft POH. Equipment configurations vary across 310 R airframes. Verify every procedure against the specific aircraft and its POH before use.

Throttles — both IDLE IMMEDIATELY Brakes APPLY FIRMLY; REMAIN ON RUNWAY If airborne at low speed below obstacle clearance: land ahead on remaining runway or suitable area.

Continental TSIO-520 is fuel-injected — classic carburetor ice does not apply. Monitor for induction icing or alternate air door function as equipped per POH. Unexplained power loss — one or both engines CHECK ALTERNATE INDUCTION AIR SOURCE IF EQUIPPED; CHECK THROTTLE, MIXTURE, FUEL SELECTOR, AND FUEL PUMP Mixture — verify RICH — RULE OUT MIXTURE-INDUCED POWER LOSS If power is not restored TREAT AS PARTIAL ENGINE FAILURE; MAINTAIN VYSE; DIVERT TO NEAREST AIRPORT

An engine-out go-around is high-risk. Commit only if landing is clearly not possible and sufficient altitude, airspeed, and runway remain for a safe climb on one engine. Operating engine throttle FULL FORWARD — SMOOTH AND IMMEDIATE Rudder FULL TOWARD OPERATING ENGINE TO MAINTAIN DIRECTIONAL CONTROL Pitch for Vyse DO NOT ALLOW SPEED TO DECAY; ACCEPT SINK RATE UNTIL AT OR ABOVE VYSE Flaps — retract incrementally EACH STEP IMPROVES CLIMB PERFORMANCE; DO NOT RETRACT ALL AT ONCE AT LOW SPEED Landing gear — after positive rate of climb RETRACT Feathered engine REMAIN FEATHERED; DO NOT ATTEMPT RESTART DURING GO-AROUND Climb — if altitude cannot be maintained LAND STRAIGHT AHEAD ON REMAINING RUNWAY OR BEST AVAILABLE SURFACE
