I-01N Buchon

[SIZE=4]F1F-2 / FMA I-01N[/SIZE]
32 ordered by Chile for Q1/37.

In response to a specification for a carrier-based fighter Luis Barron developed a modified carrier fighter based on the FMA I-01 differing only in structural weights, addition of a rear fuselage fuel tank and carrier-operation gear. The Navy quickly turned down the I-01N in favour of Japanese fighters for both technical and political reasons. One surplus standard fighter was fitted with catapult spools and arrester gear in July 1936 and used for dummy deck landing trials. In late 1936 Chile ordered 32 I-01N fighters for delivery from February 1937. These aircraft have the construction numbers C/N17001-C/N17032

The Chileans first saw the F4U at Talons 1939, and the aircraft's performance impressed all of the pilots present, who then took back favorable reports for both the Chilean Navy Air Arm and the Chilean Air Force. The Navy showed more interest in the type, as they sought a replacement for FMA I-01Ns and Spartan Corsair-IIs then in service. The Naval Air Arm was in the final stages of completing and adopting the new Alicanto naval bomber, and had arranged for the acquisition of Spartan I-02N fighters; however, the AdCAA exhibited a strong preference for radial-engine aircraft, which the I-02N was not.

In 1940, the AdCAA requested ENAER's opinion on the Vought F4U design, and ENAER's general manager opened discussions with Chance-Vought to investigate purchasing a production license. The Navy concurred, and agreed to place a minimum order for license-built F4Us, making the specification that the license-built aircraft must mount the Austral Incitatus radial. As this engine was roughly similar in power, weight, and size to the American Pratt & Whitney R-2800 Double Wasp already on the Corsair, this change was believed to be fairly easy; however, it still caused nearly four months of delay as engineers from ENAER and Vought attempted to work things out.

The initial Chilean experience with the Corsair did not prove positive. The Chileans, like the USN, saw problems with low-speed stall performance, visibility while landing on carrier decks, and over-sprung landing gear which caused the aircraft to bounce in heavy deck landings. A major crash on the carrier Libertad resulting in the aircraft being temporarily grounded. However, the Armada persisted and ENAER made a number of changes to rectify the situation, placing stall strips, modifying the landing gear, and installing bubble hoods. Production shifted to the new model, called the F4E-2, by April 1941, and all F4E-1 Corsairs were rebuilt to the F4E-2 standard by July. Basic specifications of the F4E-1 and F4E-2 remained the same in most respects.

The ENAER F4E-3 is largely identical to the American F4U-4 Corsair, with ENAER working with Chance-Vought to improve the preceding Corsair design. Like the preceding F4E-2, ENAER built over 85% of the aircraft using indigenous development, although some difficult-to-manufacture parts were sourced from the US or Atlantis, The F4E-3 was highly regarded by the Armada, but the FACh ended up with first priority for ENAER's production, ordering ninety-six planes in late 1941.
