Analysis

N323EA was stopped 44 ft prior to the final turn off point for it's gate allowing the tail to extend 21 ft beyond the limit line. 9VSQQ was taxiing at 'pilots discretion' along the taxiway centerline when an attempt was made to pass behind N323EA at a 90 deg rt angle. The rt wing of 9VSQQ collided with the thrust reverser and tail pipe of N323EA. The crew of 9VSQQ stated they saw N323EA, but felt sufficient clearance exsisted btwn the two acft. N323EA'S thrust reverser was destroyed and 9VSQQ'S rt wing tip was ripped from leading to trailing edge. N323EA had strobe lights operating while stopped on the ramp. The captain of 9VSQQ warned the first officer just prior to the collision, 'don't look at the strobes they'll blind you.'
