Narrative:

During taxi to final parking, we were marshalled in and experienced a minor wing to wing contact with another parked B-757. Our B-757 entered the ramp at dsm at approximately XA33Z. WX was good and dry ramp. Marshalling picked up our aircraft and marshalled us to the northwest ramp area. I immediately observed that there would be tight maneuvers. I told the first officer to monitor the wingwalker on the right side of the aircraft and to apply brakes if he felt the need or was signaled by the wingwalker to stop. I then devoted my attention to the marshaller on the nose of the aircraft. Both marshallers continued our taxi with no indication of impending wingtip clearance problems. The first officer said we might hit the B-757 and to stop. I immediately stopped. The marshallers never gave us a sudden or any other indication to stop our taxi during this time, we did not feel any hit at all. Maintenance, after inspecting the aircraft, marshalled the aircraft to our final parking spot. After parking, I exited the aircraft for the post flight inspection. I noticed the right wing strobe lack of judgement on behalf of the marshaller and wingwalker.

Title: WINGTIP TO WINGTIP COLLISION.

Narrative: DURING TAXI TO FINAL PARKING, WE WERE MARSHALLED IN AND EXPERIENCED A MINOR WING TO WING CONTACT WITH ANOTHER PARKED B-757. OUR B-757 ENTERED THE RAMP AT DSM AT APPROX XA33Z. WX WAS GOOD AND DRY RAMP. MARSHALLING PICKED UP OUR ACFT AND MARSHALLED US TO THE NW RAMP AREA. I IMMEDIATELY OBSERVED THAT THERE WOULD BE TIGHT MANEUVERS. I TOLD THE FO TO MONITOR THE WINGWALKER ON THE R SIDE OF THE ACFT AND TO APPLY BRAKES IF HE FELT THE NEED OR WAS SIGNALED BY THE WINGWALKER TO STOP. I THEN DEVOTED MY ATTN TO THE MARSHALLER ON THE NOSE OF THE ACFT. BOTH MARSHALLERS CONTINUED OUR TAXI WITH NO INDICATION OF IMPENDING WINGTIP CLRNC PROBS. THE FO SAID WE MIGHT HIT THE B-757 AND TO STOP. I IMMEDIATELY STOPPED. THE MARSHALLERS NEVER GAVE US A SUDDEN OR ANY OTHER INDICATION TO STOP OUR TAXI DURING THIS TIME, WE DID NOT FEEL ANY HIT AT ALL. MAINT, AFTER INSPECTING THE ACFT, MARSHALLED THE ACFT TO OUR FINAL PARKING SPOT. AFTER PARKING, I EXITED THE ACFT FOR THE POST FLT INSPECTION. I NOTICED THE R WING STROBE LACK OF JUDGEMENT ON BEHALF OF THE MARSHALLER AND WINGWALKER.
