Continued Airworthiness (Continuing Airworthiness)

Section 02: Regulatory Vocabulary

Definition

The set of processes, activities, and arrangements that ensure an aircraft continues to meet its approved type design requirements and remains in a condition for safe operation throughout its operational life. Continued airworthiness encompasses the TC holder's obligation to provide maintenance and operational instructions (Instructions for Continued Airworthiness — ICA), the operator's responsibility to maintain the aircraft per the approved maintenance program, the authority's mandatory corrective actions (Airworthiness Directives), and the systematic monitoring of the in-service fleet.

Where This Shows Up

Continued airworthiness responsibilities are shared among multiple parties: the TC/STC holder must develop ICAs and address unsafe conditions; the registered owner/operator must perform maintenance and comply with ADs; the State of Registry must provide regulatory oversight. This lifecycle approach to safety extends from certification through the entire service life of the aircraft.
