This directive addresses a known safety issue identified by the manufacturer.\n- **Compliance deadline:** The work had to be completed within **100 hours of flight time** after 31 August 1972.\n- **Grandfathering:** If an aircraft owner already complied with an earlier version of this directive, that counts as compliance with this updated version (Amendment 2).\n\n**In short:** This is a historical aircraft safety mandate requiring a specific mechanical fix on a popular single-engine aircraft, with a built-in grace period for compliance and recognition of earlier repairs."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The amendment specifies compliance with Beechcraft SI No. 0254-156, Rev. IV and retains applicability to all Beechcraft 35 models (Applicability; Requirement). The directive explicitly accepts compliance under a previous issue as meeting this amendment (Note).
