The known number of products in compliance:

Total Costs of compliance for U.S. fleet: $3,636,513

Costs covered under warranty (if known) $0

Special considerations for Economic Analysis (Use this field to explain anything in the Estimated Costs table that 

was assumed or might not be obvious. This field can also be used to explain warranty costs): Total cost will vary

depending on inspection method used. Total estimate here will use the higest cost per product 

(Ultrasonic).
Estimate of time for inspection adjacent to a lap splice repair is for one repair only. Will have to 

multiply this estimate by the number of lap splice repairs on the airplane. One repair is included in the 

total cost of compliance.

Repair cost estimate is for one typical repair only and does not include time to manufacture parts. If 

multiple repairs are required, will have to multiply this estimate by the total number of repairs being 

accomplished. Not included in total cost of compliance as repairs may not be required after each 

inspection interval.

Executive Order 12866:

Could the AD be considered a “significant regulatory action”?

YES* NO 

*Explanation: 

DOT Regulatory Policies and Procedures:

Is the AD significant? 

YES* NO 

*Explanation: 

Regulatory Flexibility Act:

Will the AD have a significant economic impact on a substantial number of small entities? Explain for 

either a Yes or No answer.

YES NO 

Explanation: The frequency of inspections (every 500 flight cycles) and the cost to accomplish the 

inspection, in conjunction with finding inspection space with authorized inspectors, could create 

issues with small and large entities complying with this AD.

Intrastate Aviation in Alaska:

This AD could affect intrastate aviation in Alaska. Is it appropriate to include specific requirements for 

aircraft operated in Alaska where aviation might be the only mode of transportation?

YES* NO
