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): 

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 February 4, 2014. 

According to the manufacturer, all of the 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.
