Narrative:

While taxiing the aircraft I had multiple training aircraft on both sides with minimal clearance and [another aircraft] ahead on my right side. Because of the planes being on both sides and the [other aircraft] on the right; I was navigating between the planes and attempting to judge distances of clearance. While looking to the right side to ensure clearance of the [other aircraft]; my left wing struck the rudder of a small plane that was in a blind spot of visibility. [The cause was a] loss of situation awareness and blind spot. [I suggest having] wing walkers/linemen assistance in safely guiding [a] plane out of [an] overly crowded area.
