Final answer:
The methods used to deter or prevent condemned aircraft parts from being reinstalled in an airworthy aircraft include tagging or marking, logbook entries, and physical destruction.
Step-by-step explanation:
The methods used to deter or prevent a life-limited (condemned) aircraft part from being reinstalled in an airworthy aircraft include:
- Tagging or marking: The condemned part may be clearly tagged or marked to indicate that it is not to be used again.
- Logbook entries: The condemnation of the part can be documented in the aircraft's logbook, ensuring that future inspections and maintenance will identify the part as unsuitable for use.
- Physical destruction: In some cases, the condemned part may be physically destroyed, such as by cutting it into smaller pieces or applying significant damage, making it impossible to reinstall in an airworthy aircraft.
