Agricultural Aviation, Ag-Av, was one the largest aerial agriculture operators in Queensland.
                                 Its aircraft worked throughout south-eastern Queensland from its base at Archerfield.    David
                                 Carter caught one of its Pawnees, VH-KRT, parked at Thangool on April 28, 1976.       The
                                 aircraft had been FIRST registered in October 1965.     Agricultural aircraft often spend long
                                 periods off the register, sometimes due to accidents, sometimes because of a downturn in business.
                                 –KRT was absent from July 1978 to March 1980 and from March 1983 to March 1985, with
                                 the aircraft BEING shown as withdrawn from use.     On February 1, 1986 it suffered an engine
                                 failure on take off from Lady Barron airport on Flinders Island and was damagED.  .  It suffered
                                 its worst accident on August 22, 1987 when it struck a tree near Nhill, Victoria, and crashed to
                                 the ground killing the pilot.       The wreckage was sold to Gippsland Aeronautics, which used
                                 components to make one of the two prototypes of the GippsAero GA-200 Fatman.   Production
                                 GA-200s were manufactured from scratch.    –KRT was sold in China in May 1993 as B-8512.
