### Special considerations for Economic Analysis (Us e this fie ld to explain anythin g in the Estimated Costs tabl e that was assumed or might not be obvious. This field can also b e used to explain warranty costs): 

### The parts cost to replace the LCEs is not included in the estimate. 

### It is considered, "Parts and Materials Supplied by the Operators," in Boeing Alert SB 747-27A2506, dated February 3, 2014. The parts cost to replace the 

### IB elevator PCPs and install external IB elevator compensators, doesn't include the cost of the 

### IB elevator PCPs. They are considered, "Parts and Materials Supplied by the Operators , " in Boeing Alert SB 747-27A2513, dated Februar y 4 , 2014. According to the manufacturer, all ofthe costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. The cost for operators to revise their maintenance program to incorporate CMRs (27-CMR-1 0 & 

### 27-CMR-11 ), and the cost of the repetitive lubrication and freeplay inspection specified in these CMRs, is not included in our cost estimate.
