FAA COMPLIANCE TIMING & RELIABILITY TARGETS
LIFESPAN PROJECTION CALCULATED
B10 LIFE (10% FAIL) 1605 hrs
MEDIAN LIFE (50% FAIL) 5753 hrs
B10 represents the age at which 10% of components fail. Often utilized as the baseline safety interval for scheduling initial borescope or overhaul checks.
DEGRADATION MODE CLASSIFICATION β = 1.48
Wear-Out (Increasing Failure Rate)
Failure rate increases with operating time. Driven by physical degradation like fatigue, lubrication loss, rotor wear, or insulation breakdown. Requires scheduled replacement intervals.
