Cat A includes which entries?

• A. Line Tasks
• B. All of the above
• C. Only sign own work
• D. Can sign CRS of others

Answer: (B)

Cat A describes the scope of authorization for line maintenance certifiers and what they may certify for release to service. This includes the line maintenance entries themselves (Line Tasks) that a Cat A certifier can sign off, and it also covers the ability to sign the Certificate Release to Service for work performed by others when the certifier is properly authorized and has verified the work. In addition, Cat A certifiers are responsible for signing off work they have personally performed or supervised, reinforcing accountability for the release. Because Cat A encompasses all these aspects, the option that includes every listed entry best matches the scope of Cat A.
