This directive ensures a known safety issue is addressed before it causes an accident.\n- **Compliance deadline:** The work had to be completed within **100 hours of flight time** after 31 August 1972.\n\n**Note:** This is **Amendment 2** of the directive, meaning it has been updated twice since originally issued. The original directive dates back to August 1972, making this a long-standing safety requirement for this aircraft type."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The instrument is marked \"Amdt 2,\" indicating it is an amendment, but the provided text does not describe the prior version or any change in who or what is covered.
