A Beechcraft 200C Super King Air, F-GRSO, sustained substantial damage in a landing accident at Nouméa-La Tontouta International Airport (NOU), New Caledonia.
The airplane operated on a flight to Nouméa's Magenta Airport when, during the approach, the crew noted that the undercarriage did not lock down. The alternate gear extension procedures were used, but did not result in a down and locked indication. The crew then decided to divert to La Tontouta Airport. A low pass along the control tower confirmed that the undercarriage was extended. Nevertheless, the gear indication still did not show that it was locked.
During the landing roll, the main gear collapsed. The aircraft stopped on the runway.

Probable Cause:

CONCLUSION (translated from French):
The rupture of two teeth of the sprocket of the control cylinder of the left main landing gear caused the cylinder to be locked and thus caused the mechanical system to extend the landing gear. This blockage prevented the complete extension and locking of the landing gear.
This rupture and other damage to the two main landing gear actuators was probably the result of improper installation of the toothed gear and / or improper adjustment of the assembly.
