Specifically, they must follow instructions in a Cessna Service Information Letter (SIL No. SE 80-24) to prevent a dangerous mechanical failure.\n\n**Who it affects:** \n- Owners and operators of Cessna Model U206 aircraft with serial numbers U2060487 through U20605619\n- Owners and operators of Cessna Model P206 aircraft with serial numbers P2060001 and P2060191 through P20600647\n\n**Why it matters:** The turbocharger has an \"anti-rotation pin\" that can fail. If this pin breaks, it can get sucked into the scavenge pump (part of the oil system), which could then cause both the pressure pump and scavenge pump to fail. This could lead to catastrophic engine failure in flight.\n\n**What must be done:** The required inspection or modification must be completed within 100 hours of flight time after 30 June 1980, following the manufacturer's service letter.\n\n**Note:** This references a US Federal Aviation Administration (FAA) directive (AD 80-07-01), showing Australia adopted this safety requirement from the American regulator."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-206-32-turbocharger","history":"/api/acts/ad-cessna-206-32-turbocharger/history","analysis":"/api/acts/ad-cessna-206-32-turbocharger/analysis","conflicts":"/api/acts/ad-cessna-206-32-turbocharger/conflicts","importantCases":"/api/acts/ad-cessna-206-32-turbocharger/important-cases","documents":"/api/acts/ad-cessna-206-32-turbocharger/documents"}}
