What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On Sunday June 19, 2016, a Beechcraft model 58 baron experienced a nose landing gear collapse while landing on runway 17 at Dallas Executive Airport (rbd), Dallas Texas. An onsite investigation was conducted and the nose gear retraction mechanism was examined in detail.
This examination showed the drag brace had fractured in the tubing; at a point just forward of the right attach point. The fracture faces displayed surfaces that were inclined at approximately 45-degrees to the axis of the separated portion of the tubing, consistent with an overload event. Additionally, signs of rust were found along the fracture. It appears that internal corrosion lead to an undetected stress crack, causing the overload condition.
