AD 2013-11-11

We are superseding AD 2000-04-01 that applies to certain Cessna Aircraft Company (Cessna) Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H airplanes. AD 2000-04-01 currently requires an inspection of the engine oil pressure switch and, if applicable, replacement of the engine oil pressure switch. This AD increases the applicability of the AD, places a life-limit of 3,000 hours time-in-service on the engine oil pressure switch, and requires replacement when the engine oil pressure switch reaches its life limit. This AD was prompted by new reports of internal failure of the engine oil pressure switch, which could result in complete loss of engine oil with
consequent partial or complete loss of engine power or fire. We are issuing this AD to correct the unsafe condition on these products.
