What is one key factor in determining whether an aircraft can be classified under a special C of A - Limited?

• A. The aircraft must be over 30 years old
• B. The aircraft must have been used in military operations
• C. The aircraft must not have features making it unsafe under limitations
• D. The aircraft must have undergone recent maintenance checks

Answer: (C)

The classification of an aircraft under a special Certificate of Airworthiness (C of A) - Limited is fundamentally linked to safety considerations. One of the key factors is that the aircraft must not have features that would render it unsafe under the limitations imposed by this type of certificate. This implies that, even if an aircraft is older or has a specific history, it must still meet safety standards and operational limitations defined under the regulations.

A special C of A - Limited is often issued for aircraft that might not meet the full airworthiness standards but can still be considered safe for specific uses or operations. These might include experimental use, aerial work, or other non-commercial applications where stringent limitations on operations may be appropriate.

The other options do not directly address the core requirement of safety and compliance with limitations for aircraft under this certificate. While age, military use, and recent maintenance checks may be relevant to overall aircraft safety and suitability for operation, they do not specifically dictate the classification status under a special C of A - Limited in the same fundamental way that safety under limitations does.
