NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

On April 18, 2014, about 1340 Pacific daylight time (PDT), a McDonnell Douglas Helicopter (MDHI) 500N, N522GS, right rear landing gear strut failed during landing, and while attempting to set the helicopter on the ground, the front strut also collapsed at Santa Monica Airport (SMO), Santa Monica, California. The owner/pilot was operating the helicopter under the provisions of 14 Code of Federal Regulations (CFR) Part 91. The private pilot and three passengers were not injured; the helicopter sustained substantial damage to the front landing gear structure. The local personal flight departed Camarillo, California, about 1315, with a planned destination of Santa Monica. Visual meteorological conditions prevailed, and no flight plan had been filed.

The substantial damage to the helicopter was not discovered until the maintenance facility began to repair the helicopter. On June 19, 2014, NTSB was notified and provided photographs of the structural damage to the helicopter and determined the damage was sustantial.


The landing gear strut assembly has been removed from the helicopter and sent to McDonald Douglas Helicopters, Inc., (MDHI) for further examination.
