VH-AEA  (3)  Beech A56TC/A1 Baron                                    (c/n  TG-91)


                                      This, the third allocation of the rego VH-AEA barely creeps in under my inclusion criteria, having
                                      been first registered in September 1970.   Geoff Goodall took the above shot at Cairns in August
                                      1974 at which time the aircraft was owned by Queensland Aerial Survey Company Pty Ltd and
                                      the inscription on the fin reads 'Qasco Air Surveys'.  This large aerial survey company had taken
                                      over Adastra in 1976.    This aircraft is actually quite rare.  Only 12A56TC Turbo Barons (its
                                      correct designation) were built.   It differed from the standard 56TC Turbo Baron (and only 82
                                      of those were produced) in minor system and trim changes.  Power was supplied by two Lycoming
                                      TI0-541-E1B4 turbocharged engines in enlarged nacelles.  This aircraft went on to perform other
                                      survey tasks with Airesearch Mapping Co of Brisbane well into the new millennium, although it is no
                                      longer on the register.
