Unsafe Condition
Fatigue failure of the crosstube assembly due to excessive stress during run-on landings, which may cause cracking in the area above the skid tube saddle and subsequent loss of control of the helicopter.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Create a component history card or equivalent record for each crosstube assembly. Determine and record the accumulated Retirement Index Number (RIN) for each crosstube assembly based on run-on landings or time-in-service. Replace any crosstube assembly on or before reaching 5,000 RIN. Revise the Airworthiness Limitations section of the maintenance manual to establish a retirement life of 5,000 RIN for the affected crosstube assemblies.
