Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 727, 727C, 727-100, -100C, and -200 series airplanes. This proposal would require an inspection of the forward trunnion attach fittings of the main landing gear (MLG), inspections of the attach fitting holes of the forward trunnion attach fittings if necessary, replacement of the forward trunnion attach fittings if necessary, and corrective actions if necessary. This action is necessary to detect and correct cracks and corrosion on the attach fitting holes of the forward trunnion attach fittings of the MLG, which could result in the collapse of the MLG. This action is intended to address the identified unsafe condition.
