The NTSB's narrative for the Beechcraft BE99 final · quoted from the NTSB record
A Beech 99 and a Cessna 402 were substantially damaged in a ground collision that occurred during night taxi operations at General Mitchell International Airport (MKE), Milwaukee, Wisconsin. Both pilots followed each of the controller's instructions to proceed to the same cargo ramp using intersecting taxiways after having landed. Neither controller had advised either pilot that other aircraft would be approaching the same taxiway intersection. Neither pilot reported seeing the other airplane approaching the taxiway intersection. The Cessna 402 landed on runway 25R and was instructed to taxi to the cargo ramp via Golf, Bravo, and Alpha taxiways. The Beech 99 landed on runway 25L. The taxi instructions given to the Beech 99 pilot were to turn right at taxiway A2 (high-speed taxiway), monitor ground on frequency 121.8, and taxi to the cargo ramp. The local controller reported he scanned taxiway A, the runway, and saw the Beech 99 clear of the runway. As the Beech 99 prepared to turn off taxiway A2 onto taxiway A, the Cessna 402 approached the taxiway A and taxiway A2 intersection. The Beech 99's right propeller impacted the Cessna 402's left wing tip fuel tank. The impact of the two airplanes resulted in a fire. Both of the pilots involved in the ground collision evacuated their respective airplanes. The FAA Order 7110.65, "Air Traffic Control," states that the absence of holding instructions authorizes an aircraft to cross all taxiways and runways that intersect the taxi route. FAA Order 7110.65, "Air Traffic Control," states that it is the procedure for controllers to instruct aircraft where to turn off the runway after landing and advise the aircraft to hold short of a runway or taxiway if required for traffic. Neither aircraft was issued hold short instructions. The Airport Surface Detection Equipment Model X (ASDE-X), provided images of each airplane's movement leading up to the time of the ground collision. The ASDE-X replay showed the Beech 99 taxiing at 20 knots on taxiway A2 approaching the taxiway A intersection. The Cessna 402 was shown taxiing at 20 knots just short of the taxiway A and taxiway A2 intersection. Both pilots reported that they did not see the other airplane approaching the same intersection while taxiing. Title 14 Code of Federal Regulations Part 91 states that vigilance shall be maintained by each person operating an aircraft so as to "see and avoid" other aircraft.

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 docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site 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 CHI07FA060.
