It originally required inspections of 'fatigue critical items' — parts of an aeroplane that are prone to wear and tear from repeated stress (like metal fatigue from takeoffs and landings). The directive has been cancelled because its requirements are now covered by a broader Structural Integrity Program under a different directive (AD/F28/45). Aircraft operators no longer need to follow this specific directive, but must comply with the replacement program instead."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The instrument cancels the original AD/F28/12H and transfers its inspection requirements to a Structural Integrity Program Document specified in AD/F28/45.
