## Summary

We propose to adopt a new airworthiness directive (AD) for all Model 757 airplanes. This proposed AD would require repetitive inspections for corrosion and cracking in the front spar lower chord at the four fastener locations common to the side link support fitting at wing station (WS) 292, and corrective actions if necessary. This proposed AD results from reports that several operators have found cracking in the front spar lower chord at the four fastener locations common to the side link support fitting at WS 292. We are proposing this AD to detect and correct such corrosion and cracking, which, if not corrected, could grow and result in structural failure of the spar.
