(.19) on June 28, 2002 at 1450 eastern daylight time, a Beech 58, N9098Q, collided with the runway during a landing at Nashville International Airport in Nashville, Tennessee. The airplane, registered to and owned by flight express, inc., was operated by the airline transport pilot, accompanied by a company mechanic. The maintenance flight was conducted under the provision s of title 14 CFR part 91 with no flight plan filed. Neither occupant sustained injuries, however, the airplane was substantially damaged. The flight originated from Nashville International Airport, in Nashville, Tennessee, at 1430. According to the pilot, this flight was necessary to complete the annual inspection of the airplane. The purpose of the flight was to verify engine takeoff RPM and to verify throttle position for the landing gear warning horn micro-switches. The takeoff and climb were typical, and the gear warning horn was tested during downwind. The gear warning horn did not sound when the throttle was reduced. However, when the landing gear lever was lowered for landing, the landing gear light illuminated. After touchdown, the landing gear collapsed.
