Several motors and batteries are swapped between identical aircraft without recording which component was used where. What future problem can this create?

Answer

The operator can lose track of component age, cycles, fault history, and maintenance status. Use the level of component tracking required by the manufacturer and the operator's maintenance system.

Explanation

Interchangeable parts are convenient, but maintenance decisions still need history. Without traceability, a suspect component can move through the fleet unnoticed.
