This aircraft was delivered to the US Army in November 1964, s/n
63-13128, and struck off charge December 1976. It was acquired as a surplus aircraft by the
Pittsburgh Institute of Aeronautics (PIA). The plane was used for seven years as an
instructional airframe in several aircraft maintenance and avionics courses.
In the early eighties six Westinghouse J34 jet engines were obtained by PIA. To
operate the jet engines the Mohawk was chosen as an engine test stand and fitted
with two jet engines under the wing next to the original two Lycoming T53
turboprops. In 1985 the conversion was ready and this Mohawk became the only
four-engined aircraft of the type with all engines operational, although the
aircraft never left the ground in this configuration. The aircraft was sold several
years ago, without the jet engines.
Restored to the original OV-1A configuration, it was registered as N87864, and is
now on loan to the American Wings Air Museum at Anoka, Minnesota.
