NTSB summary

Following push back from the gate, as the captain was taxiing the airplane from the ramp to the runway, the left horizontal stabilizer struck the right horizontal stabilizer of a parked company airplane at an adjacent gate, resulting in substantial damage to both airplanes' flight control surfaces. According to the flight crew statements and a Federal Aviation Administration (FAA) inspector who responded to the accident site, the parked airplane had been improperly parked with the right wing tip and horizontal stabilizer well outside the safety lines.
Verbatim, NTSB aviation accident database (narratives.narr_accf).

Probable cause

The flight crew's failure to adequately monitor and maintain clearance from a parked aircraft while taxiing. Contributing to the accident was an improperly parked airplane that encroached upon the taxiway area.
