What condition must be met for a standard airworthiness certificate to remain in effect?

A standard airworthiness certificate remains in effect as long as the aircraft meets specific maintenance and inspection requirements set forth by aviation regulations. This encompasses routine maintenance checks, such as scheduled inspections and adherence to airworthiness directives, which are essential for ensuring that the aircraft continues to conform to its original design and is in a safe operating condition.

The maintenance and inspection requirements include both annual and 100-hour inspections, along with any necessary repairs that may arise during operations. This ensures that any issues that could affect safety are addressed promptly, thus maintaining the certificate's validity.

Ultimately, for an aircraft to retain its airworthiness, it is crucial that all applicable maintenance and inspection protocols are followed stringently, reflecting the ongoing safety standards required by aviation authorities.
