Abstract SAFAT01 is a locally assembled light aircraft; design documents are troublesome as they are usually not sold to the buyer as part of the contract. If it is required to make any modifications, aerodynamic and else wise analyses   become prerequisites. This work aimed to predict aerodynamic & stability data for SAFAT01. Because of its economic and time efficiency, DIGITAL DATCOM program has been used to predict the stability and control derivatives for the subsonic, low angle of attack-less than 15 degree- flight regimes. DATCOM aerodynamic results when compared to CFD were very close. The effect of nominal center of gravity position was considered. According to computed stability results, the aircraft has been found statically stable and possessing stable longitudinal dynamics. This agrees with the flight tests results conducted on the aircraft which showed stable behavior.

Keyword: aerodynamic, stability, DATCOM.
