The pilot received an unsafe landing gear indication for the left main landing gear when he configured the airplane for landing. He cycled the gear and then attempted a manual extension, both without success. The pilot then completed the landing on the nose and right main landing gear. A post accident examination of the left main landing gear actuator revealed that the supports for the actuator bearings lacked lubrication and that the bearings displayed wear due to inadequate lubrication.
The commercial pilot reported that he was en route to a parachutist jump zone on the first of two planned jumps. Prior to the first jump, before he had slowed the airplane, or illuminated the green jump light, indicating that the parachutists had permission to jump, two of the parachutists prematurely jumped.
A skydiver jumped up and out of the airplane instead of dropping out of the exit and keeping a low trajectory. He then impacted the horizontal stabilizer and fell away from the leading edge. The skydiver’s automatic deployment system activated and opened the parachute.
