Some front frames may provide mounting for what?

• A. Accessories
• B. Fuel lines
• C. Igniters
• D. Bleed air ports

Answer: (A)

Front frames are structural sections that provide a mounting surface for engine accessories. The front frame typically includes an accessory drive area and mounting points to support components like fuel pumps, oil pumps, generators, starters, and other accessory gear that need to be driven from the accessory drive. This arrangement keeps these external components aligned and securely attached to the engine, ensuring reliable operation and proper drive synchronization. In contrast, fuel lines are routed through the engine and connected to pumps and injectors, igniters sit in the combustion system, and bleed air ports are part of the compressor/bleed system, not mounting points on the front frame. So, some front frames are specifically designed to provide mounting for accessories.
