Once again, an ac (A320 N855NW taxiing) has clipped the horizontal stabilizer of another one (Horizon's DH-8 awaiting for gate), this time at Portland on the 29th Sep. 2005.
Out of curiosity, what may be the cause(s) of these repeated close encounters? Too tight space at gates, airport procedures, congested taxiways,...
It does not seem (but I may be wrong) that so many incidents of the kind occur in Europe.
On the other hand, the FAA reports openly any incident right away. We cannot say the same about the EASA (only 3 years old).
