When Tri-9 took over, the two aircraft owned by the airline were in very poor shape and were ferried to Seletar, Singapore for overhauling. One of the aircraft (8Q-AM101, Flying Fish I) was found to be beyond economic repair and was stored at Seletar, where it remained until it was broken up. It was replaced in October 1976 by another Convair 440 aircraft (reg. N90907) which was owned by Tri-9. Meanwhile, Flying Fish II (8Q-AM102) underwent a major overhaul and entered service again in November 1976.
