## Components from aircraft involved in accidents, including engines and engine parts, are sometimes sold for use on airworthy aircrafts. Please be advised that whenever a TURB OMECA engine or engine part is subjected to stresses, thermal effects or other damage beyond normal operating parameters some ad verse change in that part may occur. Such a change may not be visually detectable and would therefore require destructive testing to determine airworthiness. Unless you can evaluate stresses, thermal effects or other damage to which parts are subjected as the result of an accident and determine that the parts still conform with th eir design standard, you should assume that any part that may affect sa fe operation of the aircraft is damaged beyond acceptable limits and must not be re-used. All information and data appearing in this technical instruction are the exclusive property of TURBOMECA. They are made available to the operato r of the engine under a restrictive licence from TURBOMECA for the so le purpose of enabling safe operation and maintenance of the engine. Any other use of this information and data is subject to the prior agreement of sales terms with TURBOMECA.

## All scheduled or unscheduled ma intenance procedures carried out pursuant to a maintenance document (Maintenance Manual, Technical Instruction, Maintenance T echnical Instruction) must be recorded in the relevant engine log book section(s), on the exchangeable supply log card (module) or the log card (accessory) where applicable. All modifications made pursuant to a Service Bulletin must be recorded in the relevant engine log book secti on(s), on the exchangeable supply log card (module) or the log card (accessory) where applicable. Failure to record incorporation of these maintenance procedures or modifications could result in uns afe engine usage conditions which could compromise flight safety.
