The NTSB's narrative final · quoted from the NTSB record

THE INCIDENT TRANSPORT AIRPLANE COLLIDED WITH ANOTHER PARKED TRANSPORT AIRPLANE WHILE TAXIING AWAY FROM A GATE AT THE START OF A REVENUE FLIGHT. BOTH AIRPLANES SUSTAINED MINOR DAMAGE. THE PILOT STOPPED THE AIRPLANE AND SHUT IT DOWN. THE PASSENGERS AND CREW DEPLANED USING THE NORMAL CABIN EXITS. THE INVESTIGATION REVEALED THAT SIGNALMEN AND WINGWALKERS WERE ROUTINELY GROUND GUIDING AIRCRAFT AT THAT PARKING LOCATION TO A PARKING SPOT THAT WAS DISPLACED TO THE LEFT OF THE PAINTED TAXI GUIDE STRIPES. THIS PRACTICE ALLOWES THE TAIL OF A DEPARTING AIRPLANE TO TRANSCRIBE AN ARC WHICH PASSES THROUGH AN ADJACENT DEDICATED PARKING SPACE AS IT TURNES AWAY FROM THE GATE. WHEN THIS SPACE IS OCCUPIED BY A LONGER AIRPLANE THERE IS INSUFFICIENT CLEARANCE TO ALLOW THE TAIL SURFACES OF THE TWO AIRCRAFT TO CLEAR EACH OTHER. ACCORDING TO RAMP PERSONNEL AN EMERGENCY STOP HAND SIGNAL WAS ISSUED BY THE WINGWALKER BUT WAS NOT RECOGNIZED IN TIME TO STOP THE INCIDENT.

About this page

Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number CHI91IA073.
