Which component is mounted on the excessive drive housing?

Which component is mounted on the excessive drive housing?

• A. Starter motor
• B. Lube oil filter
• C. Pressure sensor
• D. Fuel pump

Answer: (B)

The question focuses on which subsystem is integrated with the accessory drive housing on a gas turbine engine. The accessory drive housing powers and supports several engine accessories, and the lubrication system is designed to be routed through this same area. Placing the lube oil filter on the accessory drive housing allows the oil to be filtered as part of its return path before it’s circulated to the bearings and gears, and it keeps maintenance access convenient since the filter is right where the driven pumps and lines are located. While other components like a starter motor or fuel pump are often found on the accessory drive, the design in this case specifically places the lube oil filter there.
