NTSB Issues Safety Recommendation to Hawker Beechcraft Regarding Beechcraft 1900D Nose Landing Gear Fatigue Life

The National Transportation Safety Board (NTSB) has issued safety recommendation number A-13-004, identified by reference number CEN11IA341, addressed directly to the Hawker Beechcraft Corporation. This directive requires the manufacturer to conduct a comprehensive determination of the fatigue life, specifically the life limit, for the nose landing gear (NLG) end cap found on the Beechcraft 1900D aircraft. The investigation focuses on analyzing the structural integrity under two distinct conditions: first, when the longitudinal grain direction is aligned with the longitudinal axis of the nose landing gear, and second, when it is not aligned. This request aims to clarify the operational limits of this critical component to ensure continued airworthiness and safety standards for this specific aircraft model.
