Unsafe Condition
LP compressor blade partial airfoil release events. This AD aims to prevent LP compressor blade airfoil separations, damage to the engine, and damage to the airplane.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Perform ultrasonic inspections (UIs) of the low-pressure (LP) compressor blades. Initial inspections are required for blades with less than 1,800 cycles since new (CSN) or cycles since last inspection (CSLI). Repetitive UIs are required before exceeding 2,400 cycles since last inspection (CSLI). Blades exceeding 1,800 CSN on the effective date must be inspected before exceeding 600 flight cycles or 3,600 CSN, whichever comes first, followed by repetitive inspections before exceeding 2,400 CSLI.
