Summary
On April 15, 2013, a Beech A36 (N1820L) was involved in an incident near Port Alsworth, AK. All 4 people aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The failure of the left main landing gear retraction brace assembly, resulting in the collapse of the left main landing gear.
The pilot was landing the airplane on a dry, unpaved airstrip, when the left main landing gear retraction brace assembly (PN 35-815125-2) broke, and the left main landing gear collapsed. The airplane sustained substantial damage to the left aileron. The pilot stated that there were no preaccident mechanical anomalies with the airplane.
Examination of the airplane's maintenance logbooks revealed no record that the brace assembly had ever been replaced during the airframe's time in service of 19,770 hours. The brace is a on-condition replacement part.
This incident is documented in NTSB report ANC13CA038. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N1820L.
