Narrative:

I was doing an ETOPS check on aircraft X. At the time; I was servicing the oxygen system. To service the oxygen on the B757 the service port is at the forward cargo section. At the time I pulled up to the aircraft with the oxygen cart; a belt loader pulled up to the forward cargo door to load cargo. When I was finished servicing the oxygen; I pulled away from the aircraft being careful not to hit the #2 engine cowl at the same time moving forward. I didn't notice that the ladder that was attached to the oxygen cart was modified and was 12 inches higher than the old ladder. Moving forward concentrating on the #2 engine; I hit the wing to body fairing putting a 6 inch gouge in it. I immediately informed my supervisor.
