Entry Authority certification is valid for how long?

• A. 1 year
• B. 2 years
• C. 3 years
• D. 6 months

Answer: (A)

Entry Authority certification is a currency that must be kept up-to-date. In aviation maintenance settings, credentials that grant access or authority to perform restricted tasks are issued for a fixed period to ensure the holder’s knowledge, procedures, and safety practices reflect current standards. The certification is valid for one year from the issue date, after which it expires unless renewed. Renewal typically involves a refresher or requalification process and supervisor sign-off to confirm ongoing competency and awareness of any changes since the last certification.

Longer durations like two or three years would allow drift in procedures and safety practices, while a very short period like six months would add unnecessary rework without significant safety benefit. The one-year validity strikes a balance between ensuring currency and manageable revalidation.
