Narrative:
Martinaire Flight 679, a Cessna 208B Super Cargomaster, N4602B, enroute to George Bush Intercontinental/Houston Airport (KIAH) in Houston, Texas, has impacted the terrain of Victoria County northeast of its point of departure at Victoria Regional Airport (KVCT) in Victoria, Texas.
After departing from Runway 13L at 20:02, air traffic control (ATC) directed the pilot to climb and maintain 3000 ft mean sea level (msl). After climbing through 1900 ft msl, the airplane began a series of fifteen course reversals, which continued throughout the remainder of the flight. The course reversals alternated between right and left turns, each with more than 90 degrees of heading change. ATC queried the pilot several times concerning the airplane's erratic course. At 20:08 and 20:11, the pilot stated that he had "some instrument problem" and after a suggestion by ATC, the pilot agreed to return to VCT. As the airplane continued to make turns, a rapid descent occurred, and radar contact was lost.
The airplane impacted a rural area at a near vertical attitude, with the propeller hub buried about 5 ft deep into clay soil. The airplane was highly fragmented, with remnants of the fuel tank and engine tubing located 225 ft from the main wreckage.
