Helicopter Pilots: Check Shafts Instead of Swapping Every Time
Published Date: 1/16/2026
Rule
Summary
If you fly Airbus EC130B4 or EC130T2 helicopters, listen up! The FAA updated the rules: instead of always swapping out the center shaft, you can now inspect it regularly for cracks and only replace it if needed. This new rule starts February 2, 2026, and helps keep flights safe without breaking the bank.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
Inspections Instead of Blanket Replacement
If you operate an Airbus Helicopters Model EC130B4 or EC130T2, beginning February 2, 2026 you must repetitively inspect the center shaft assembly for cracks and replace it if it fails the inspection or exceeds a certain hours time-in-service (TIS). For certain center shaft assemblies, the FAA determined a repetitive inspection is adequate instead of mandatory replacement; initial inspections for certain parts may be required within 10 hours TIS from the effective date.
Explicit Compliance Cost Estimates
The FAA estimates this AD affects 304 U.S.-registered helicopters. The AD lists estimated compliance costs: an inspection costs $170 per helicopter (2 work-hours at $85/hour, $0 parts) and replacing the center shaft assembly costs $27,910 per helicopter (12 work-hours at $85/hour = $1,020 plus $26,890 parts). The FAA estimates total U.S. operator costs of $51,680 for inspections and $8,484,640 for replacements.
Special Flight Permits Prohibited
The AD explicitly prohibits special flight permits for affected helicopters. This prohibition is effective with the AD on February 2, 2026 and means operators cannot obtain special flight permits to fly those helicopters under the conditions the AD addresses.
Ban on Installing Non-Serviceable Shafts
The AD prohibits installing a center shaft assembly that is not a serviceable center shaft assembly on any EC130B4 or EC130T2 helicopter. The prohibition is carried forward from the prior AD and remains effective as of February 2, 2026.
