Otter 178 was the last of six Otters delivered to Philippine Air Lines (PAL), being delivered on 22nd November 1956 with registration PI-C56. Following its test flying at Downsview, it was packed into a crate, shipped to Manila and re-assembled, entering service with PAL on its 'rural air service'. PI-C56 was destroyed on 27th July 1962 in a crash at Mutya, Oriental Misamis in somewhat mysterious circumstances. It crashed in a forest some forty miles south of its planned course, killing the pilot and the sole passenger, who was a suspected criminal wanted on several charges. The cause of the crash was never established.
