Event Date: 1990-12-03 at 1345 EST Investigative Body: National Transportation Safety Board (NTSB), USA Investigative Body's Web Site: http://www.ntsb.gov/ Cautions: 1. Accident reports can be and sometimes are revised. Be sure to consult the investigative agency for the latest version before basing anything significant on content (e.g., thesis, research, etc). 2. Readers are advised that each report is a glimpse of events at specific points in time. While broad themes permeate the causal events leading up to crashes, and we can learn from those, the specific regulatory and technological environments can and do change. Your company's flight operations manual is the final authority as to the safe operation of your aircraft! 3. Reports may or may not represent reality. Many many non-scientific factors go into an investigation, including the magnitude of the event, the experience of the investigator, the political climate, relationship with the regulatory authority, technological and recovery capabilities, etc. It is recommended that the reader review all reports analytically. Even a "bad" report can be a very useful launching point for learning. 4. Contact us before reproducing or redistributing a report from this anthology.

Appendix ..F Runway Incursion Recommendation Summary 160 EXECUTIVE SUMMARY On December 3, 1990, at 1345 eastern standard time, Northwest Airl ines flight 1482, a McDonnell Douglas DC-9, and Northwest Airl ines flight 299, a Boeing 727, collided near the intersection of runways 09/27 and 03C/21C in dense fog at Detroit Metropol itan/Wayne County Airport, Romulus, Michigan. At the time of the collision, the B-727 was on its takeoff roll, and the DC-9 had just taxied onto the active runway. The B-727 was substantially damaged, and the DC-9 was destroyed. Eight of the 39 passengers and 4 crewmembers aboard the DC-9 received fatal injuries. None of the 146 passengers and 10 crewmembers aboard the B-727 were injured. The National Transportation Safety Board determines that the probable cause of this accident was a lack of proper crew coordination, including a virtual reversal of roles by the DC-9 pilots, which led to their failure to stop taxiing their airplane and alert the ground controller of their positional uncertainty in a timely manner before and after intruding onto the active runway. Contributing to the cause of the accident were (1) deficiencies in the air traffic control services provided by the Detroit tower, including failure of the ground controller to take timely action to .alert the local controller to the possible runway incursion, inadeauate visibility observations, failure to use progressive taxi instructions in low-visibil ity conditions, and issuance of ina.o.o ro. ~riate and confusina taxi instructions compounded by inadequate backup supervision for the level of experience of the staff on duty; (2) deficiencies in the surface markings, signage, and lighting at the airport and the failure of Federal Aviation Administration surveillance to detect or correct any of these deficiencies; and (3) failure of Northwest Airl ines, Inc., to provide adequate cockpit resource management training to their line aircrews. Contributing to the fatalities in the accident was the inoperabil i ty of the DC-9 internal tailcone release mechanism. Contributing to the number and severity of injuries was the failure of the crew of the DC-9 to properly execute the passenger evacuation. The safety issues raised in this report include: Airport marking and lighting; Cockpit resource management; Air traffic control procedures in low-visibil ity conditions; Flight attendant procedures during evacuations; Design of the DC-9 tailcone emergency release system. Recommendations concerning these issues were addressed to the Federal Aviation Administration, the Detroit Metropolitan/Wayne County Airport, and Northwest Airlines, Inc.
