When may an aircrew member be grounded due to Injury Flight Evaluation (IFE)?

An aircrew member may be grounded due to Injury Flight Evaluation (IFE) primarily when the member is injured. This situation typically arises when the physical condition of an aircrew member is deemed to interfere with their ability to perform flight duties safely and effectively. In cases of injury, there must be a careful assessment to determine if the member can safely operate the aircraft or perform other critical duties associated with aircrew responsibilities.

Grounding due to injury is a protective measure, ensuring that the injured member receives appropriate treatment and that the overall safety of the crew and the mission is maintained. This grounded status remains in effect until the individual has sufficiently recovered and cleared any medical evaluations necessary to return to flight status.

In contrast, the other scenarios mentioned do not directly relate to a grounding condition due to injury. Resignation, evaluating new equipment, or being unfit for flight may involve operational considerations, but they do not pertain specifically to the need for grounding due to physical harm sustained by the member.
