• C. MEL/AD do not affect type-rated aircraft.
• D. MEL/AD apply only to maintenance crews.

Answer: (A)

MELs (Minimum Equipment Lists) and Airworthiness Directives (ADs) are about keeping an aircraft legally airworthy and safe to operate. For a type-rated airplane, you must stay current with the MEL limitations that apply to that specific aircraft and with any ADs that affect it. ADs are mandatory changes issued by the aviation authority to address safety issues and may require inspections, repairs, modifications, or even grounding of affected aircraft until compliance. The MEL defines what inoperative equipment is tolerable under defined conditions, so flight operations can continue legally when something is not working, but only within those specified limits. Together, they directly influence how you operate the type-rated aircraft and whether you’re permitted to fly it, which is why this topic is essential for maintaining a type rating.
