You endorsed a commercial applicant for added category and class privileges to solo in that category and class. If you place no limitations on the endorsement, does it expire?

• A. Yes, it expires after one year
• B. No, it does not expire unless otherwise specified
• C. It expires after six months
• D. It expires when the applicant changes category or class

Answer: (B)

Endorsements to solo in a newly added category and class are a formal authorization from the flight instructor for the student to fly solo in those specific category/class privileges. If you don’t put any time limit or other conditions on that endorsement, there isn’t a built-in expiration date. It remains valid until you specify otherwise or unless something changes that would require a new endorsement—such as the student moving to a different category or class, or the instructor revoking the endorsement.

Keep in mind that even with no expiration, the student still must meet general currency and safety requirements to operate solo, so ongoing flight experience rules still matter.
