(1) WARRANTY: Lycoming Engines, a division of Avco Corporation (hereinafter “Lycoming”) warrants each new and rebuilt Lycoming reciprocating engine to be free from defect in material or workmanship under normal use and service for a period of twenty-four (24) months or the recommended engine time (hours) between overhauls (“TBO”) in accordance with the latest edition of Lycoming Service Instruction 1009, whichever occurs first. Lycoming’s sole obligation under this warranty is limited to replacement or repair of parts which are determined by Lycoming to have been defective within the warranty period. The warranty period commences on: (a) the date of first operation after new aircraft delivery to the original retail purchaser or first user; or (b) twenty-four (24) months from the engine ship date from Lycoming, whichever occurs first.
(2) HIGHLY UTILIZED ENGINES / LYCOMING LOYALTY PROGRAM WARRANTY: Additionally, Lycoming also warrants the crankcase, crankshaft, cylinders*, sump, accessory housing and all internally lubricated parts to be free from defects in material or workmanship under normal use and service for an additional twelve (12) month period from the warranty period applicable in (1) above on highly utilized engines that consistently accumulate forty (40) or more flight hours per month. This additional twelve (12) month warranty period is limited to new or rebuilt engines purchased on an exchange basis in accordance with a Lycoming Loyalty program through an Authorized Lycoming distributor.
The Lycoming website does seem give additional warranty cover for 40+ hours pcm, but not really a guarantee of making TBO as far as I know
