Therefore, for airplanes on which STC ST01518SE is installed, a "change in product" alternative method of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17. (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Unsafe Condition This AD was prompted by a report of cracks found in the fastener holes at a certain location on the center wing box rear spar, lower skin. The FAA is issuing this AD to detect and correct cracking that, if undetected, could result in the inability of a principal structural element to sustain limit load, which could adversely affect the structural integrity of the airplane.

(4) Where note (b) in Sheet 3 of Figure 1 of Boeing Alert Requirements Bulletin 757-57A0075 RB, dated August 25, 2021, specifies "as an accepted procedure," this AD requires omitting that phrase.
