AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Track-and-balance blades that are 5 years old or have 1,000 hours time-in-service (TIS). Replace blades with airworthy ones before further flight if abnormal vibration occurs within 5 hours TIS after track-and-balance. Replace blades with airworthy ones other than P/N A016-1 for helicopters with blades P/N A016-1 or A016-2, depending on TIS or age. Determine the age of each blade and revise the component history card or equivalent maintenance record for blades P/N A016-2, adding a 10-year retirement life.
