PI-C-53?  de Havilland Canada DHC-3 Otter            (c/n 72)

                            

                              Consensus of opinion among de Havilland of Canada officianados is that aircraft most likely became
                              PI-C53 upon being uncrated in the Philipinnes early in 1955.   I am frankly surprised that the Canadian
                              DoT or Transport Canada, or whatever it was known as in those days, permitted even test flight or
                              photo-op sorties without displaying some form of ferry markings.  PI-C53 was the third of six Otters
                              which were used by PAL in their "Rural Air Service" operation, providing air transportation between
                              remote villages scattered throughout the many islands of the nation with larger centers of commerce.
                              Such service, possible only with STOL aircraft, provided hitherto unheard of convenience, eliminating
                              days, or even weeks of ground travel to a matter of a minutes or hours.   "Rural Air Service" ran for
                              about a decade but was then unfortunatly suspended following the crashes of four of the Otters.
                              The remaining two were used on charter services ntil 1968 when both returned to Canada.  PI-C53
                              became CF-XUX.
