When would depot maintenance personnel complete an overhaul of the BEAR Power Unit?

• A. After 12000 hours
• B. After 24000 hours
• C. After 36000 hours
• D. After 48000 hours

Answer: (B)

Maintenance planning for a BEAR Power Unit uses a scheduled overhaul at a defined number of operating hours to catch wear before it leads to failures. For this unit, depot-level overhaul is planned after about 24,000 hours of operation. Reaching that interval allows technicians to perform a thorough teardown, inspect all major assemblies, and replace or refurbish components that wear with use—such as bearings, seals, and other critical parts—so the unit can be reassembled and tested to bring it back to like-new reliability. Choosing this point in time balances reliability and downtime: it gives enough runtime to justify the overhaul by addressing wear proactively, while avoiding pushing the unit into a higher-risk condition that could occur with longer intervals. The depot overhaul also often includes reconditioning or replacing parts that affect performance and efficiency, rechecking tolerances, and calibrating controls to ensure the unit meets specifications after service.
