Which of the following aircraft would require an annual inspection?

The correct answer is focused on the specific requirements for annual inspections based on the type of airworthiness certificate the aircraft holds.

A small single-engine turboprop with a restricted airworthiness certificate is indeed subject to certain operational limitations, and while it may require inspections, these do not typically include the standardized annual inspections required for aircraft with standard airworthiness certificates.

In contrast, a small multiengine turboprop aircraft with a standard airworthiness certificate is explicitly required to undergo an annual inspection. This is because all aircraft with a standard airworthiness certificate must comply with the annual inspection requirement to ensure they meet safety standards for operation.

Provisional airworthiness certificates for rotorcraft indicate that the aircraft is undergoing specific evaluation and may have restrictions on its operation. These aircraft do not typically require annual inspections in the same manner as those with standard certificates.

Therefore, while each aircraft may have inspection requirements, the only one that universally mandates an annual inspection is a small multiengine turboprop with a standard airworthiness certificate. This underscores the focus on the type of airworthiness certification when determining inspection requirements.
