Maintaining Airworthiness Limitations for Life-Limited Parts in Mature Engines
Turbine engine Life-Limited Parts (LLP) are those parts whose primary failure is likely to result in a hazardous engine effect. These parts require replacement, inspection, and other procedures at specific times in their life cycle given their implications for safety. Proper operating configuration management of LLP – including other parts that influence the LLP operating conditions – is critical to ensuring that the Airworthiness Limitation established by the Type Certificate (TC) Holder remains valid over the life of a part.
