Key Takeaways:

The Air Force has grounded some of its C-130H Hercules cargo transports after cracks were discovered in older propeller barrel assemblies.
The issue was initially found by a technician at Warner Robins Air Logistics Center, prompting widespread inspections and an immediate-action technical order.
Only C-130H aircraft equipped with older 54H60 propeller assemblies are affected, while C-130J models and C-130H aircraft with upgraded NP2000 propellers are not.
Up to 116 C-130Hs could be grounded as a result of the inspections and propeller replacements.
