Who takes responsibility in the absence of an assigned Crew Chief?

The flight engineer or senior maintenance man assumes responsibility in the absence of an assigned Crew Chief due to their experience and knowledge of aircraft systems and operations. These individuals are typically well-versed in both the technical aspects of maintenance and the operational procedures required to ensure safe and effective aircraft performance. Their training equips them to make informed decisions in critical situations, allowing for continuity in leadership and accountability during flight operations.

In contrast, a junior technician may lack the necessary experience to take on such responsibility, while a Tool Room Supervisor primarily focuses on inventory management and tool availability rather than direct aircraft oversight. A Program Manager operates at a higher administrative level, focusing on broader operational or managerial aspects, rather than direct involvement in day-to-day maintenance or flight operations.
