**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 hig est 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 spli ce repairs on the airplane. On e repair is included in the total cost of compliance. Repair cost estimate is for one ty pical repair onl y 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.
