HISTORY OF FLIGHT
On April 8, 2003, at 1850 central daylight time (CDT), a Dassault DA-20C, Fan Jet Falcon, N179GA, operated by Grand Aire Express, Inc. as flight GAX179, was destroyed when it was ditched into the Mississippi River near St. Louis, Missouri. The airplane was approaching to land on runway 30R (9,003 feet by 150 feet), at the Lambert-St. Louis International Airport (STL), when it lost power to both engines. The 14 CFR Part 135 non-scheduled domestic cargo flight was operating on an instrument flight rules flight plan in instrument meteorological conditions at the time of the accident. The pilot and first officer received serious injuries. The airplane departed from the Del Rio International Airport, Del Rio, Texas, about 1630.
The airplane received vectors from air traffic control (ATC) for the instrument landing system (ILS) 30R approach to STL. During the first approach, the STL tower controller initially cleared the airplane to land on runway 30R. Later, the airplane was instructed to climb to 3,000 feet and to contact departure control. The airplane was then vectored for a second approach to runway 30R. While being vectored for the second approach, the flight crew asked controllers several times how far they were to be vectored away from the airport. When the airplane was on a base leg for landing, the flight crew reported that they had a "fuel limitation." They were then immediately issued vectors and cleared for the ILS 30R approach. After being switched to the tower frequency, the flight crew declared an emergency. The crew reported to the tower controller that they lost power to both engines. The airplane was subsequently ditched into the Mississippi River.
In an interview after the accident, the pilot-in-command (PIC) stated that during the first approach to land, when they were inside the outer marker of the approach, ATC instructed them to climb to 5,000 feet and "fly the heading." He stated that they were then vectored for another approach. The PIC stated that during the second approach they asked ATC how far out they were going to be taken and ATC responded 20 miles. He said that they were again cleared for the approach, intercepted, and broke out of the overcast. He stated that they went about 1 1/2 miles after that when the engines failed. He stated that during the second approach they questioned ATC several times as to how far away from the airport they were going to be taken on the approach. The PIC stated that they informed ATC of their fuel situation. He stated that they also asked ATC why they had been instructed to go-around on the first approach and that ATC did not give them an answer. The PIC stated that he had been assigned to the airplane since April 5, 2003, and that there were no problems with the airplane. In a later telephone interview, the pilot stated that the airplane had departed DRT with 6,200 pounds of fuel on board. The pilot subsequently provided a load manifest that indicated that the airplane was limited to 25,000 pounds takeoff weight due to runway and climb limitations. The manifest showed that the actual takeoff weight was 24,646 pounds.
In an interview after the accident, the second-in-command (SIC) stated that they had received vectors for the ILS 30R approach and that everything went "fine" until they were less than 7 miles from the airport. At that point, ATC instructed them to climb to 5,000 feet. He said that they were then vectored for another approach, during which time, they were sent 23 miles west of the airport, and then 17 miles east of the airport prior to being vectored back to the final approach for runway 30R. He stated that their fuel was critical and that the right engine stopped producing power about 15 miles from the airport. He said that the left engine stopped producing power about 30 seconds after the right engine stopped producing power. When questioned as to why he thought the engines stopped producing power, he said that they "ran out of fuel." He stated that when the right engine failed the fuel quantity indicator read zero, and when the left engine failed the fuel quantity indicator read 100 pounds. When asked if there were any problems with the airplane the SIC responded "No, the airplane was good." He also stated that after being instructed to climb to 5,000 feet after their first approach, he questioned the PIC about landing at the Spirit of St. Louis airport. The SIC said that the PIC elected to continue with the second approach to STL. The Spirit of St. Louis Airport is located about 14 nautical miles west-southwest of STL.
According to personnel statements made by FAA Air Traffic Control Specialists, the accident airplane was given missed approach instructions during its first instrument approach when adequate separation from another arriving aircraft could not be maintained.
PERSONNEL INFORMATION
The PIC held an airline transport pilot (ATP) certificate issued by the Federal Aviation Administration (FAA) on April 13, 2001.
