JA5139 was one of four Beech H18s
originally to have been acquired from Japan Air Lines by Trans
West Air Charter of Perth, Australia. JAL had used several of
the type for crew training and executive
leasing. They were all low hours and in excellent shape.
However, just before their delivery in the early
1970s, Australia's DCA announced that they considered them to be so
different from tail wheeled D18S
UC-45 variants that they required a complete new type certification .
Since this would have been
for TWAC the deal fell through and the H18s were disposed of elsewhere.
This one went
Indonesia where it became PK-BIF. The above image is
