10.6 Continuing Airworthiness Flashcards
What is an airworthiness directive?
Is a document issued or adopted by the CAA which mandated actions to be performed on an aircraft to restore acceptable level of safety
When shall the CAA issue an airworthiness directive?
An unsafe condition has been determined by the CAA, that condition is likely to exist or develop in other aircraft
What does the type certificate holder do after getting given an AD?
