## Summary

This document proposes to supersede Airworthiness Directive (AD) 91-14-14, which currently requires repetitively inspecting the main landing gear (MLG) ``A'' frame assemblies for cracks on Raytheon Aircraft Corporation (Raytheon) Model 76 airplanes, and replacing any assembly found cracked. Reports of fatigue cracks developing on the MLG ``A'' frame assemblies of the affected airplanes prompted AD 91-14-14. Raytheon has developed improved design MLG ``A'' frame assemblies, and the Federal Aviation Administration (FAA) has determined that Model 76 airplanes with an improved design ``A'' frame assembly installed on both the left and right MLG should be exempt from AD 91-14-14. This proposed action retains the requirement of repetitively inspecting the MLG ``A'' frame assemblies for cracks and replacing any cracked ``A'' frame assembly only for those Model 76 airplanes that do not have the improved design parts installed. The actions specified by the proposed AD are intended to prevent MLG failure because of a cracked ``A'' frame assembly, which could result in loss of control of the airplane during landing operations.
