On November 19, 1996, at 1701 central standard time, United Express flight 5925, a Beechcraft 1900C, N87GL, collided with a Beechcraft King Air A90, N1127D, at Quincy Municipal Airport, near Quincy, Illinois. Flight 5925 was completing its landing roll on runway 13, and the King Air was in its takeoff roll on runway 04. The collision occurred at the intersection of the two runways. All 10 passengers and two crewmembers aboard flight 5925 and the two occupants aboard the King Air were killed. Flight 5925 was a scheduled passenger flight operating under 14 Code of Federal Regulations Part 135. The flight was operated by Great Lakes Aviation, Ltd., doing business as United Express. The King Air was operating under 14 Code of Federal Regulations Part 91.
The National Transportation Safety Board determines that the probable cause of this accident was the failure of the pilots in the King Air A90 to effectively monitor the common traffic advisory frequency or to properly scan for traffic, resulting in their commencing a takeoff roll when the Beech 1900C (United Express flight 5925) was landing on an intersecting runway.
Contributing to the cause of the accident was the Cherokee pilot's interrupted radio transmission, which led to the Beech 1900C pilots' misunderstanding of the transmission as an indication from the King Air that it would not take off until after flight 5925 had cleared the runway.
Contributing to the severity of the accident and the loss of life were the lack of adequate aircraft rescue and fire fighting services, and the failure of the air stair door on the Beech 1900C to open.
Safety issues discussed in the report include the importance of emphasizing careful scanning techniques during flight training, Beech 1900C certification standards and compliance with requirements on door jamming, the certification of small airports used by scheduled commuter airlines, and aircraft rescue and fire fighting protection on scheduled commuter aircraft having 10 seats or more. Safety recommendations concerning these issues were made to the Federal Aviation Administration.
As a result of the investigation of this accident, the National Transportation Safety Board makes the following recommendations:
To the Federal Aviation Administration:
Reiterate to flight instructors the importance of emphasizing careful scanning techniques during pilot training and biennial flight reviews. (A-97-102)
Evaluate the propensity of the Beech 1900C door/frame system to jam when it sustains minimal permanent door deformation and, based on the results of that evaluation, require appropriate design changes. (A-97-103)
Establish clear and specific methods for showing compliance with the freedom from jamming certification requirements. (A-97-104)
Consider the circumstances of the November 19, 1996, Quincy, Illinois, accident when developing methods for showing compliance with freedom from jamming requirements, and determine whether it is feasible to require that doors be shown to be free from jamming after an impact of similar severity. (A-97-105)
Review and improve, as necessary, guidance for principal maintenance inspectors to use in ensuring that maintenance personnel are properly trained in accomplishing the maintenance tasks that they are assigned. (A-97-106)
Develop ways to fund airports that are served by scheduled passenger operations on aircraft having 10 or more passenger seats, and require these airports to ensure that aircraft rescue and fire fighting units with trained personnel are available during commuter flight operations and are capable of timely response. (A-97-107)
Add to the Safety Information Section of the FAA's Internet Home Page a list of airports that have scheduled air service but do not have aircraft rescue and fire fighting capabilities. (A-97-108)
Permit scheduled passenger operation only at airports certificated under the standards contained in Part 139, "Certification and Operations: Land Airports Serving Certain Air Carriers."
