Aero Mercantil sa developed the eight seat single piston-engine utility monoplane, the Gavilan, able to operate from short and unprepared airstrips. First flown in April 1990, production began in 1997, by El Gavilan sa.

Aeromarine PG-1
Built by Engineering Division and Boeing in 1922 as an army ground-attack pursuit aircraft, the PG-1 had a 37mm cannon in its propshaft and lots of armor plate. Ultimately it was rejected because of pilot’s lack of forward visibility. First flying on 22 August 1922, three were built (AS64245-64247). The first PG-1 went to McCook Field as project P-240. The only pursuit aircraft with a “PG” designation, which was later transferred to the Powered Glider category. A second type of engine was tried in the PG-1; the Packard 1A of 350 hp.

Aeromarine-Klemm AKL-26 / AKL-27 / AKL-60 / AKL-85 / L-26
About 10 of the 1930 AKL-26 (ATC 203) were built, including 3 AKL-60 prototypes, and one as the AKL-26 Special (ATC 2-111) in 1932 for twin-float modification. New price was US$3,500 or $4,500 as a floatplane.
The AKL-26A (ATC 204) of 1929 was fitted with an extra fuel tank, selling for US$3,550. About 40 were built, of which at least one, NC163M, was refitted with 80hp Genet engine. In 1934 a twin-float conversion, N159M, was made as the Uppercu AKL-26A (ATC 2-466).
The AKL-26B / AKL-85 / Model 85 Flyer (ATC 334) of 1930 sold new for US$$3,700, $3,300 in 1931 or $4,700 as floatplane (ATC 2-467). At least 14 were built, of which some were converted to AKL-27, also produced in 1930.
The AKL-26 Special (AKL-26X) (ATC 2-404) NX15640 c/n 2-64 was built in 1932, powered by a 65hp Velie M-5 engine.

AKL-60
Boland L-25 / Aeromarine-Klemm AKL-25 / Klemm L.25
Designed from the Hans Klemm powered glider design, the L.25, one prototype was built in 1928, plus several registered as Leicht-flugzeugbau L-25.
The AKL-25 made its public debut at the 1928 Nationals where, with its gliderlike characteristics, it won the dead-stick landing contests.
The design became production Aeromarine-Klemm AKL-25A. About 60 of the AKL-25, AKL-25A aka L-25A were built, of which some were converted to AKL-26A. Production was superseded by the AKL-26.

Aeromarine HS
The Aeromarine HS of 1921 was an Aeromarine conversion of surplus Curtiss HS-2L open cockpit flying boat, using the wings and engine structure with an Aeromarine hull. Possibly only one was built.
Lady Baltimore II pictured here was the short-lived Easter Airways’ plane, displaying part of a commercial “FOR NEURALGIA” message on the underside of its top wing… an additional source of revenue.
Aeromarine EO Turtle
The Aeromarine aluminum hulled EO was built in 1924 and first flown in that June, with a shoulder mounted 80 hp Anzani radial engine. Developed from the Aeromarine AMC, the EO was a sesquiplane, the wings were braced by V-struts.
The EO is an open cockpit aluminum-hulled biplane seaplane with a single tractor engine center mounted in a nacelle on the top wing which also housed the fuel tank and oil tank. The upper wing is staggered well forward of the lower wing. The wings are constructed with spruce I-beam spars and ribs with aircraft fabric covering. The hull is built with four watertight compartments. The tip floats are all-aluminum. A cross-through tube accepted a wheel assembly for ground movement.
The Aeromarine EO was designed as an updated replacement to the Aeromarine Model 44 for the customer Earl Dodge Osborn. Osborn was a former accountant for Aeromarine, assistant editor of Aviation magazine and future founder of Edo Aircraft Corporation. The aluminum hull was scaled down from the Aeromarine AMC design, offering advantages in durability, weight and the inability to become waterlogged.
One EO is known to have been completed in 1924, re-engined with a 90 hp Kinner K-5 in 1929 and was destroyed in a crash at Cape May NJ on 12/15/31.
The first flight tests were performed by Osborn in June 1924. The EO was used for demonstration flights for the EDO company. It then transferred ownership several times with a planned flight to Peurto Rico. It was listed as “Washed Out” at Cape May, New Jersey and its registration was cancelled on 21 January 1932.
A reported second or modification to a larger fin, and increased dihedral may have become the Edo Model B.

Aeromarine AMC / Aeromarine Metal Commercial
Similar in configuration to the Curtiss HS series, the AMC (Aeromarine Metal Commercial) was an effort to introduce a civil flying boat of conventional two-bay biplane design that possessed a more modern airframe, most notably an all-duraluminium hull and a dural-framed empennage.
The 1923 AMC was built with spruce I-beam spars and ribs, dural-framed empennage; fabric-covered wings and tail; all-duraluminum hull. The AMC was designed to replace the 75s of Aeromarine Airways and first flew on 1 June 1923.
The AMC flew for the first time in June 1923 and soon afterwards commenced a trial route between New York and San Juan, Puerto Rico, however, Aeromarine and its airline subsidary ceased operations in late 1923, and no more AMCs were completed.
The Morro Castle II can be recognized by its shorter lower wings.
While not a commercial success, the AMC did establish a new standard for flying boats with more durable metal hulls.
Long before Photoshop, this bit of “creative enhancing” asks more than it tells. It could be a short-wing version of AMC, dubbed Morro Castle II, but its placement in an Egyptian setting is a mystery—perhaps for an ad with a relevant headline. The plane appears to be pasted on the background—a small seam below the rudder hinge is visible. If it is supposed to be landing, it is doomed. The prop is stopped and the pilot sits on the coaming away from the controls, which are set for a severe left hand dive into the Nile.
