Pitch control rod bearings are elastomeric and should be inspected for ____/____ on preflight.

Pitch control rod bearings are elastomeric and should be inspected for ____/____ on preflight.

• A. Corrosion/Rust
• B. Damage/Cracks
• C. Wear/Looseness
• D. Bleed/Leak

Answer: (B)

Elastomeric bearings can degrade with age, heat, exposure to fluids, and recurring loads, so the preflight check targets visible signs of failure. Cracks or other damage in these bearings are clear indicators that the material has deteriorated and may not reliably support the pitch control rod, potentially leading to improper pitch control or loss of control authority. Corrosion or rust aren’t concerns for the elastomer itself, and bleed/ leak relates to hydraulic systems rather than these bearings. Wear or looseness can occur, but cracks or damaged areas provide the most definite, actionable indication that the bearing should be replaced.
