## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-8 series airplanes, that would have required an inspection to detect cracking of the swivel bogie beam lugs, and repair, if necessary. For airplanes on which no cracking is found, that proposed AD also would have required an inspection to detect corrosion of the swivel pin lug surfaces and bores, and modification of the forward bogie beams. That proposal was prompted by reports indicating that swivel pin lugs of the main landing gear (MLG) have failed due to cracks resulting from stress corrosion. The actions specified by this proposed AD are intended to prevent such stress corrosion, which could result in failure of the swivel-type bogie beam of the MLG; this condition could result in collapse of the MLG during landing. This action revises the proposed rule by adding certain repair requirements.
