Harlow PJC-2

Max Harlow was an aeronautical engineer and instructor at the Pasadena Junior College. Under his tutelage, the aircraft designated PJC-1 was designed and built as a class project.{{cite journal|journal=Air Progress Sport Aircraft|date=Winter 1969|title=The Quiet Professor|author=John Underwood}} The PJC-1 first flew on 14 September 1937 at Alhambra, California but it crashed during an extended (more than six turn) spin test with the center of gravity ballasted to the aft limit, as it was going through the certification process—a problem generally laid at the feet the unusually rigorous spin test requirement and the government test pilot, who bailed out of the airplane after the spin "flattened out." The airplane struck the ground, still in the "flat" (longitudinally level) attitude in a bean field near Mines Field (now Los Angeles International Airport) with considerable damage; although repairable, the PJC-1 was never returned to service. PJC students then built a slightly modified airplane, which limited aileron travel with full aft-stick and incorporated a slightly larger vertical stabilizer. This became the PJC-2 model, serial number 1 certified on 20 May 1938. It was one of the first, if not the first, airplane designed and built in the U.S. with a stressed-skin semi-monocoque structure—a revolutionary design feature for the time. Harlow saw the potential and formed the Harlow Aircraft Company to build PJC-2 aircraft at Alhambra Airport.Parker, Dana T. Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II, p. 128, Cypress, CA, 2013. {{ISBN|978-0-9897906-0-4}}. Four aircraft were impressed into United States Army Air Forces service with the designation UC-80 in 1942, and used by Civil Aeronautics Administration inspectors after WWII.{{cite book|title=Grand Central Air Terminal|author=John Underwood|page=95}}

The PJC-2 was an all-metal low-wing cantilever monoplane with conventional low-set tailplane and a retractable tailwheel landing gear. A tandem two-seat version intended as a military trainer was developed as the Harlow PC-5.

In 1991, 3 PJC-2s were actively flying.{{cite journal|journal=Sport Aviation|title=ANTIQUES AND CLASSICS AT OSHKOSH '91|date=November 1991}}

:Prototype, one built.

;PJC-2

:One prototype, serial number 1, a Warner Super Scarab radial engine, followed by 10 production airplanes. Most remaining examples have been re-engined with a Warner 165 HP or 185 HP engine.
