Ahrens Aircraft Corporation (Ahrens Aircraft Inc) Ahrens Aircraft Corporation was an aircraft manufacturer established at Oxnard, California in 1975 to develop a STOL regional airliner and cargo aircraft, the AR 404. The firm secured a deal with the Government of Puerto Rico to assist with development costs if the aircraft could be produced there. A prototype was actually constructed in that country, and plans were underway to build a factory at Ramey, Puerto Rico, but financial backing was withdrawn and the project was abandoned.

In order to facilitate the loading and unloading of cargo, the fuselage was of constant rectangular section along almost its entire length, the main undercarriage was retracted into sponsons on the fuselage sides, and the tail included a loading ramp. As a regional airliner, the AR 404 was designed to carry 30 passengers, or in its cargo configuration, to accommodate four standard D3 freight containers. Ahrens secured a production deal with the government of Puerto Rico, which agreed to finance the type certification of the aircraft if Ahrens would establish its production facilities there. The first production aircraft was built and flown there on October 26, 1979, but no more were constructed after financing was withdrawn.
