Narrative:
After finishing my assigned aircraft; lead directed me to assist 2 other mechanics in spoiler ehsv (electro-hydraulic servo valve) change. One of the mechanics assigned to that aircraft was going to do the replacement the other was in the flight deck operating the spoiler and hydraulics as required. So I was assigned as ground mechanic giving clearance to the flight deck mechanic to power on/off hydraulics and spoiler. Mechanic replacing valve requested hydraulics on and spoiler deployed. I relayed the message to flight deck mechanic; when mechanic removed spoiler lock; the spoiler came down and caught mechanics arm for about 15-20 seconds then shot up and deployed releasing his arm.
