2024-30785. Airworthiness Directives; General Electric Company Engines

Estimated Costs

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators
FPI the CCA forward flange	8 work-hours × $85 per hour = $680	$0	$680	$2,031,840

The FAA estimates an average CCA utilization of 2,143 part cycles per year. Based on this life estimate, the FAA is providing an estimated annual cost to replace these parts. The FAA estimates that 369 affected engines will require CCA replacement at 28,500 part cycles since new (PCSN), 855 affected engines will require CCA replacement at 25,500 PCSN, and 1,764 affected engines will require CCA replacement at 40,000 PCSN. The following summarizes the costs of the proposed AD over the analysis timeframe, for the 12 years spanning 2024-2036. The cost of early CCA removals, required by this proposed AD, analyzed over 2024 through 2036, are $265 million at a 2% financial discount rate.

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators annualized (2% discount rate)
Replace the CCA (prorated part cost)	8 work-hours × $85 per hour = $680	$646,900	$647,580	$24,544,532
