In addition to Appendix D, which aircraft type requires rotorcraft-specific items during an annual inspection?

• A. Balloon
• B. Rotorcraft
• C. Multiengine airplane
• D. Glider

Answer: (B)

Rotorcraft have unique rotating components that require inspections beyond the general items listed in Appendix D. The main and tail rotor systems, the rotor drive train, and related control mechanisms introduce specific wear, damage, and safety concerns not found in fixed-wing aircraft. During an annual inspection, these rotorcraft-specific areas—such as rotor blades and hubs, mast and swashplate/pitch-change linkage, rotor drive gearboxes, rotor tracking and balance, and tail rotor components—must be checked in addition to the general Appendix D items. Balloon, multiengine airplane, and glider do not have these rotor systems, so they rely on the general items without the extra rotorcraft-focused checks. Therefore, rotorcraft is the aircraft type that requires rotorcraft-specific items beyond Appendix D.
