Pilots can perform the daily inspection themselves without needing formal certification.\n- **Part 2:** A specific action must be completed before 31 August 1979.\n\n**Why it matters:**\nOil cooler failures can cause catastrophic engine damage or failure in flight. This directive prevents accidents by ensuring defective oil coolers are identified and replaced before they fail."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":true,"description":"The entry is labelled as Amendment 2 to AD/PA-32/54 (Amdt 2), which indicates it changes the original AD/PA-32/54.
