What should be checked during a daily PM on the JBD?

• A. Only the external paint
• B. Structural condition, mounting hardware, hydraulic lines, and surface integrity; ensure it's free of leaks and properly aligned
• C. The aircraft's fuel levels
• D. The radio communications equipment

Answer: (B)

Daily PM on the Jet Blast Deflector focuses on its structural integrity and hydraulic function to ensure safe, reliable operation. You inspect the structure for cracks, deformation, corrosion, or any damage that could compromise strength. Check mounting hardware—bolts, pins, and attachments—to make sure everything is secure, undamaged, and properly fastened. Examine hydraulic lines and fittings for leaks, wear, or damage that could affect movement or control of the deflector. Look at the surface for integrity issues like pitting or gouges that could weaken the component. Verify the JBD is properly aligned with its supports and deck interface, since misalignment can affect the deflection path and potentially interfere with aircraft or personnel. Everything should be free of leaks and correctly aligned to ensure safe, dependable operation. Cosmetic items like external paint aren’t part of daily PM, and fuel levels or radio equipment aren’t relevant to the JBD’s daily inspection.
