Which of the following is NOT a step to take during a dual-engine failure in the TH-73A?

• A. Identify a landing area
• B. Maintain altitude
• C. Establish a glide
• D. Execute emergency landing procedures

Answer: (B)

In the event of a dual-engine failure in the TH-73A, maintaining altitude is not a practical or feasible step. During a dual-engine failure, the helicopter will begin to lose altitude due to the lack of thrust provided by the engines. It is crucial to identify a suitable landing area, establish a glide, and execute emergency landing procedures to ensure a safe landing.

Identifying a landing area allows for a planned approach and increases the chances of a successful outcome during a forced landing. Establishing a glide helps in managing the descent rate and controlling the helicopter's path toward the selected landing area. Executing emergency landing procedures involves following established protocols to mitigate risks and make the best use of the remaining flight capabilities.

Therefore, attempting to maintain altitude in such a scenario is impractical, as the aircraft will descend due to the engines' failure, and the focus should instead be on managing the descent and preparing for landing.
