Which of the following is NOT typically included in an Airworthiness Release?

An Airworthiness Release is a document that indicates an aircraft has been inspected and is deemed airworthy, often required prior to returning an aircraft to service after maintenance. The inclusion of certain details in an Airworthiness Release is crucial for compliance with FAA regulations and safety protocols.

The date of the last certification is not typically included in an Airworthiness Release. Instead, the document focuses on the current status of the aircraft, detailing the maintenance performed, the name of the mechanic who conducted the inspection or repairs, and the signature of the person who approved the release. These components are essential for accountability and traceability regarding maintenance work.

The time in service of the aircraft is also relevant as it informs the aircraft's operational history and maintenance schedule. However, the date of the last certification pertains more to previous inspections or certifications, which is not a necessary part of the Airworthiness Release itself, making it the correct choice for what is typically not included.
