Narrative:

After pushback from gate, engine start, and release by ramp personnel for taxi, maintenance truck approached aircraft and parked near #2 engine without our knowledge. This was probably because we were discussing a minor mechanic problem with other maintenance personnel via radio. Problem was corrected and taxi commenced. Truck was struck by flap track fairing and #2 engine cowl. No injuries.
