The claim that all stress panels must be left in place prior to towing is true.

• A. Not enough information
• B. False
• C. Depends on aircraft type
• D. True

Answer: (B)

Ground handling rules are aircraft-specific, not one-size-fits-all. Stress panels are part of the structure, but whether they stay in place during towing depends on the particular aircraft, its configuration, and the official towing procedures for that aircraft. In some setups a panel might need to remain for structural reasons or to protect equipment, while in others it might be removed or secured differently to clear tow points or prevent damage. Because towing procedures come from the aircraft’s published ground handling manual, there isn’t a universal rule that all stress panels must be left in place before towing. Always follow the specific aircraft’s towing checklist and maintenance guidance.
