If you don't comply, you can't legally fly the aircraft. This particular directive addresses a safety issue with the original filtrator assembly, likely discovered through operational experience or incidents in the United States (hence the reference to the corresponding FAA directive 75-05-02). The deadline was strict: **within 100 hours of flying time after 30 April 1975**.\n\n**In short:** If you owned one of these specific Cessna 182s in 1975, you had to swap out this engine part for a safer version within your next 100 hours of flight time."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"Based on the directive text, the scope is a focused corrective action: remove P/N B-1114-1 and install P/N B-1114-M or B-1114-RM for aircraft modified under FAA STC No. SA 2653WE, to be completed within the stated 100‑hour window (Applicability; Requirement; Compliance).
