Under Federal Aviation Regulation (FAR) 43.11, specifically for a 100-hour inspection, the maintenance record entry must contain six distinct pieces of information to be legally compliant. First, it must state the type of inspection and a brief description of the extent of the inspection. Second, it must record the date the inspection was completed. Third, the aircraft total time in service must be documented. Fourth, there must be a signature of the person approving the aircraft for return to service. Fifth, the entry must include the certificate number and type of certificate held by the person performing the work (such as an A&P mechanic). Finally, the record must include a formal statement of certification or a statement that the aircraft has been inspected in accordance with a 100-hour inspection and determined to be in airworthy condition. This formal sign-off is a critical legal document in 2026, as failure to include any of these six elements can render the aircraft unairworthy in the eyes of the FAA and potentially void insurance policies in the event of an incident or ramp check.
