_____ are valid for 12 months and lapse if requirements to maintain _____ are not completed by the end of the 12th calendar month. This requirement may extend to the end of the 15th with the approval from the commanding officer.

• A. Stan Check and CRM (12 month requirements)
• B. Medical certification renewals
• C. Flight crew licensing
• D. Annual safety training

Answer: (A)

Keeping mandatory proficiency current on a 12-month cycle is the core idea. Stan Check and CRM are the set of annual requirements that must be completed to stay current. If these aren’t finished by the end of the 12th calendar month, the status lapses, meaning you’re no longer considered current until the requirements are completed. The commanding officer can approve a brief extension to the end of the 15th month, providing a small grace period to finish the items. This structure ensures ongoing readiness while accommodating occasional scheduling challenges.

Other options involve different certification or licensing rules with their own timelines and authorities, so they don’t align with this internal 12-month lapse and CO-approved extension pattern in the same way.
