b. Required inspections and airplane logbook documentation

ACS element text (the applicant demonstrates understanding of)

General airworthiness requirements and compliance for airplanes, including: b. Required inspections and airplane logbook documentation

Bottom line

Identify the inspection program and the checks that apply to this aircraft and operation, then verify the maintenance entries and next-due limits. A statement that the airplane “had an annual” does not establish every required inspection or its present airworthiness.
