Aviation Accident Summary ATL05LA091

Newnan, GA, USA

Aircraft #1

N2113P

Piper PA-23-150

Analysis

The airplane landed on its main landing gear and after rolling out a short distance, the pilot lowered the nose wheel until it touched the runway. After the nose wheel touched down, the airplane pitched forward and all the landing gear collapsed. Further examination of the airplane revealed the top actuator bracket of the right main landing gear was broken and separated from the attach point. There was visible rust deposits at the point of cold-welded joint. Also the upper drag link of the nose gear was rusted and fractured. Post-accident examination of the maintenance performed on the right main landing gear revealed that the top actuator bracket was not of original manufacturer design standards and the repair did not meet manufacturer recommendations; the top actuator bracket was improperly cold-welded to mount instead of being replaced.
