Requires revision of the existing maintenance or inspection program, a general visual inspection for damage of a certain cotter pin present on certain configurations of the nose landing gear (NLG) strut assembly and for the modification number shown on the identification plate for the NLG strut, and modification of the NLG retraction actuator hardware on any damaged NLG strut assembly. This AD was prompted by in-service findings that a cotter pin at the main fitting joint of the NLG retraction actuator to the NLG strut showed evidence of shearing after an NLG retraction-extension cycling.
