Airworthy

An aircraft is airworthy when it meets the requirements of its type certificate and is in a condition for safe operation. Airworthiness is a continuous condition — it must be maintained through scheduled inspections, AD compliance, and proper maintenance by licensed personnel.

The Airworthiness Chain

• Valid Certificate of Airworthiness (C of A) or flight permit in force
• All applicable Airworthiness Directives complied with
• Aircraft maintained in accordance with its approved maintenance schedule
• Any defects assessed and certified as acceptable before flight
• Required equipment installed and functional (check the MEL if applicable)

PIC Responsibility

The pilot-in-command is responsible for determining that the aircraft is airworthy before each flight. This includes the pre-flight inspection, reviewing the journey log for outstanding defects, and confirming maintenance is current. If there is any doubt, do not fly.
