Summary
The left main landing gear indicated unsafe after the pilot selected gear down. The gear was recycled, and the emergency extension procedure applied with the same result. During the subsequent landing, as the aircraft slowed, the left main gear collapsed.
Inspection revealed that the left main gear trunnion pivot pin had partially seized. This had prevented both the normal and emergency extension. Although the component had been lubricated as required by maintenance procedures, the lubricant had not penetrated the full length of the pin, leading to the partial seizure.
