Summary
Requires repetitive ultrasonic test inspections of certain main landing gear shock absorbers and, depending on findings, replacement. Prompted by reported occurrences of a broken eye end of the shock absorber piston rod. A subsequent investigation determined that the cause is fatigue cracking. If not detected and corrected, this condition could lead to structural failure of the main landing gear, possibly resulting in damage to the helicopter and injury to occupants.
