On which component is the lube oil filter mounted?

• A. Exhaust pipe
• B. Turbine main casing
• C. Combustion chamber
• D. Excessive drive housing

Answer: (D)

The lube oil filter is mounted on the accessory drive housing. This housing is the hub that powers the engine’s accessories, including the oil pump, so placing the filter there keeps the lubrication loop compact, accessible for maintenance, and ensures filtered oil is readily delivered to the pump and then to the main bearings and gear train. The other locations—hot gas paths or the large turbine sections—aren’t suitable for filters or lubrication routing, so they aren’t used for mounting the lube oil filter.
