Probable cause

Inadequate visual lookout by the pilots of both aircraft, which resulted in their failure to see-and-avoid oncoming traffic. A factor related to the accident was: the sun's glare, which restricted the vision of the Cessna 172 pilot.

Analysis

Drg dep fm rwy 24 with an IFR clnc, an atlantic southeast airline flt (Embraer EMB-120, N217AS) entered a left turn to a hdg of east & climbed to an assigned alt of 5000' MSL. Before radar contact was established with ATC, the EMB-120 converged with a cap Cessna 172, N99501. The Cessna was hdg westbound toward the setting sun. Subsequently, a head-on collision occurred about 2-1/2 mi south of the arpt. Drg impact, the rgt horizontal stabilizer of the EMB-120 sepd from the acft, but it contd flying to a safe lndg. The Cessna, however, entered an unctld dscnt & crashed. A witness, who saw the collision, did not note any evasive action by either acft before impact. The crew of the EMB-120 rprtd that they saw the Cessna moments before impact. The capt of the EMB-120 said he took immediate evasive action by 'pushing' the nose down, but was unable to avoid a collision. A flt attendant on the EMB-120 recalled a 'thump' before the acft started a dscnt.
