DA42 Phase 1s includes which action?

• A. Feather failed engine
• B. Crossfeed fuel
• C. Oil Ts and Ps GREEN
• D. Magneto BOTH

Answer: (A)

When a twin-engine airplane like the DA42 loses one engine, the immediate priority is to reduce drag from the failed side so you can maintain control and climb on the remaining power. Feathering the failed engine’s propeller accomplishes this by turning the blades to a high-pitch, wind-resistant position, which dramatically decreases windmilling drag and helps the aircraft fly more predictably on the good engine.

That’s why feathering the failed engine is the action included in Phase 1 procedures: it has the biggest positive impact on safe flight in an engine-out situation. Other items like crossfeeding fuel, checking that oil temperature and pressure are in the green, or verifying magneto operation are important in their own contexts, but they are not the immediate, defining response to an failed engine during Phase 1.
