The manufacturer gives the following components of main rotor hub assembly a limited airworthiness life.
| Component | Part Number (1) | Airworthiness Life |
|---|---|---|
Airworthiness limitation for part number listed applies to all successive dash numbers for that component unless otherwise specified.
Main rotor hub tension torsion straps have an airworthiness life of 1200 hours or 48 months, whichever occurs first. The calendar life of 48 months starts when new straps are installed in a main rotor hub and blade assembly, and are subjected to rotation on the helicopter.
Retire the main rotor trunnion when the RIN = 24000. For each takeoff/lift, add two to the RIN total.
The manufacturer recommends to preform a restoration (overhaul) of the main rotor hub ever 2400 flight hours.
