If that happens, it could destroy both the oil pressure pump and the scavenge pump — potentially causing catastrophic engine failure mid-flight.\n\n**Who must comply:** This applies to:\n- Cessna Model T210 with serial numbers T210-0001 through T210-0454\n- Cessna Model 210 with serial numbers 21058140, and 21059200 through 21063954\n\n**How to comply:** Follow either Cessna Service Information Letter SE 80-24 or the equivalent US Federal Aviation Administration directive (FAA AD 80-07-01)."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The directive maintains a narrowly targeted scope matching its stated intent: inspect turbochargers on the listed Cessna 210/T210 serial numbers to prevent anti-rotation pin failure and pump ingestion.
