A 44-year-old motorcycle rider suffered possible spinal cord injuries yesterday in a dirt bike accident near Waikane Valley Road, Emergency Medical Services officials said yesterday.

EMS crews were called at 5:10 p.m. and transported the man to Waiahole Beach Park, where he was taken by a Hawai'i Army National Guard Black Hawk helicopter crew to The Queen's Medical Center, said EMS spokesman Bryan Cheplic.

Yesterday's accident was the first time that National Guard UH-60 Black Hawk crews have been pressed into service since the Army's 25th Infantry Division last month stopped flying Military Assistance to Safety and Traffic service.
