Probable cause
The failure of the right main landing gear actuator downlock spring.
NTSB analysis
In preparation for landing, the pilot lowered the landing gear and noticed the right landing gear light was not illuminated. After repeated unsuccessful attempts to lower the landing gear, he manually extended it and it appeared down and locked. The pilot then confirmed with ground personnel that all three landing gear appeared to be extended. During touchdown, the right main landing gear collapsed and the airplane swerved to the right and traveled off the side of the runway. Examination of the landing gear system revealed the right main landing gear downlock actuator spring was distorted.
