SIAI Marchetti SF.250 / SF.260 / Aviamilano F.250 / Waco Meteor

SF.260

The prototype for the SF.260 series, known as the F.250, flew for the first time on 15 July 1964. The version developed initially for civil production was manufactured at first under licence from Aviamilano by SIAI-Marchetti and is designated SF.260 (initials in SF.260 denoted design by Stelio Frati). Subsequently SIAI-Marchetti became the official holder of the type certificate and of all manufacturing rights of the SF.260.

SIAI Marchetti SF.250 / SF.260 Article

A cabin monoplane with a cantilever low wing, the fuselage is an all-metal semi-monocoque structure of relatively thick skins and minimal stringers. The wing has a metal single spar, Friese type ailerons and electric slotted flaps. The wing is NACA 64-212 at the root and NACA 64-210 at the tip. The empennage contains cantilevered flying surfaces, with a manually operated trim tab on the elevator. The retractable tricycle undercarriage has oleo-pneumatic shock absorbers and a steerable nose wheel.

Designed by Stelio Frati and built in Italy, it is a 4 seater low-wing aircraft powered by a 260 hp Lycoming and has been predominantly sold in military versions since first flying in 1966. The SF.260 received FAA certifica¬tion on 1 April 1966.

Production of SF.260s for military use continued into 1987 in three versions: the SF.260M basic trainer, the armed SF.260W Warrior trainer and light attack aircraft, and the SF.260TP, powered by an Allison 250-B17C turboprop in place of the Lycoming 0-540 piston engine of the earlier models. The airframe is common in each case, except for a lengthened fuselage for the turboprop version. The SF.260W and TP have up to four underwing pylons for a variety of light stores, including rocket and gun pods to a maximum of 300kg.

Replacing the earlier C model, the SF.260D is powered by a 260 hp (194 kW) Textron Lycoming O-540-E4A5 engine and has the aerodynamic and structural improvements developed for the military SF260M. The similar SF260W Warrior can also double as a tactical support/liaison aircraft with light weapons. Production continues in 1990 of the SF.260TP, of which more than 60 had been ordered powered by the 350 shp (261 kW) Allison 250-B17D turboprop.

Some 350 SF260s were built in the 14 years since the type first flew. By 1993 more than 700 civil and military SF.260s of all models had been completed, most of which were for export.

Waco Aircraft was founded in 1966 to build SF.260 (as Waco Meteor), and Socata Rallye Commodore (as Waco Minerva).

Waco Meteor

In 1990 the PADC in the Philippines started assembling S 211s, followed by SF 260 TPWs and SF 600 Canguro in agreement with SIAI Marchetti of Italy.

Savoia-Marchetti S.208

First flying in 1967, in 1968 the S.208 version became available, produced basically as a five-seat, more powerful version of the S.205, with some 60% of its structural components in common.

Savoia-Marchetti S.208 Article

By February 1973, approximately 80 S.208s had been delivered to customers in Europe and Africa, including 44 S.208Ms to the Italian Air Force for liaison and training duties.

A version for general duties, including agricultural and ambulance work, was developed as the S.208AG.

Savoia-Marchetti S.205 / Waco Vela II / Taurus

A four-seat development of the SA.202 Bravo, design of the S.205 four-seat all-metal light monoplane was started in March 1964, first flying in 1965, and by April of 1965 three examples had been completed. Each had a 134kW Lycoming engine fitted, but a wide range of versions subsequently became available with different engines and equipment.

Savoia-Marchetti S.205 Article

The S205/22R was never a trainer. It was the retractable version of the 205 with a franklin engine. We also had a 205R which was the same airplane with a Lycoming. The left door was a factory option.

Waco Aircraft Co [2] was founded in 1966 to build Savoia-Marchetti S.205 (as Waco Vela II and Sirius) plus turbosupercharged Taurus derivative

SIAI-Marchetti FN-333 Riviera / Nardi FN-333

The three-seat prototype of the amphibian FN-333 flying boat, designed and built by Nardi S.A., flew first on 4 December 1952. Two more prototypes were built by Nardi through the decade. In the wake of the second Nardi prototype, Fiat of Italy also built two FN.333 prototypes, but did not continue with the exercise.

The initial prototype had “guitar-pick” style tailfins, and was powered by a Continental engine with 110 kW (145 HP); there had been thought of fixing the floats to the wingtips and then folding the wing downward after water landing, but the idea didn’t survive close examination.

Following the third Nardi prototype, an exclusive manufacturing licence for the FN-333 was obtained by SIAI Marchetti in March 1959. SIAI Marchetti called the aircraft “Riviera”.

SIAI-Marchetti placed a slightly enlarged four-seat variant in production which had flown in prototype form on 8 December 1954. The first of ten pre-production Rivieras was flown in February 1962.

The Riviera used a tricycle landing gear with the nose gear tucking up into the forward hull, the main gear hinging up to be stowed in the fuselage, as well as retractable floats, hinging up to mate with the wingtips, and no wing bracing. The twin tailfins were of trapezoidal configuration and had forward fillets. Powerplant was a Continental IO-470-P air-cooled flat-six engine with fuel injection, providing 185 kW (250 HP) and driving a two-bladed propeller.

Initial production was devoted to fulfilling orders from the USA were sales were handled by the Lane Aircraft Company which purchased the airframes for assembly by Southwest Airmotive. The first four were delivered to the USA bu mid-January 1963 and more than fifty had been sold by the middle of the year.

About 24 Rivieras were built through the 1960s, the exact number being hard to determine because of double-counting of serials.

SIAI-Marchetti / Savoia-Marchetti

Societa Idrovolanti Alta Italia
Siai-Marchetti Societa Per Azioni

The original company was founded in 1915 as SIAI (Società Idrovolanti Alta Italia – Seaplane company of Northern Italy). After World War I gained the name Savoia, when it acquired the Società Anonima Costruzioni Aeronautiche Savoia, an Italian aircraft company founded by Umberto Savoia in 1915.

The name Marchetti was added when chief designer Alessandro Marchetti joined the company in 1922. Savoia-Marchetti gained prominence with the successful S.55 flying boat. Savoia-Marchetti became famous for its flying boats and seaplanes, which set numerous endurance and speed records. Favoured by Air Marshal Italo Balbo, the company began rapidly prototyping and developing a number of other aircraft, increasingly focusing on warplanes in the lead-up to World War II. However, most of S.M.’s manufacturing capabilities were destroyed in World War Two. It was renamed SIAI-Marchetti in 1943.

Since 1946 engaged in overhaul and repair work and developed new aircraft. SIAI-Marchetti only survived in postwar Italy by building trucks and railway equipment. However it still struggled with insolvency for 6 years after the war before declaring bankruptcy in 1951.

In 1953, the company reopened. Types have included SA.202 Bravo trainer produced jointly with FFA in Switzerland; S.205 four-seater and S.208 development. First flew SF.250 aerobatic trainer in July 1964; became highly successful SF.260 production aircraft for civil and military use (initials in SF.260 denoted design by Stelio Frati). In 1968 company formed a Vertical Flight Division, but increasing helicopter work became associated with Agusta and Elicotteri Meridionale. SM.1019 light multipurpose high-wing monoplane followed 1969, SF.600 Canguro transport 1979 (recently taken over by VulcanAir), and S211 jet trainer and light attack aircraft 1981.

Agusta, which had acquired 30% of SIAI-Marchetti in 1970, had increased its stake to about 60% by 1973 and reached complete ownership in 1983.

Company taken over by Aermacchi January 1997.

Short SD3.360 / 360

The 360 is a growth development of the 330 with more power, and a three foot stretch ahead of the wing and a redesigned rear fuselage and tail surfaces. An extra six seats (in two rows) were accommodated by stretching the cabin and deleting the 330’s rear loading ramp, and the tail arrangement was changed to a conventional single fin.

Short SD3.360 / 360 Article

The prototype 360 flew on 1 June 1981 and the type entered service in December 1982. First introduced with Pratt & Whitney Canada PT6A-45R engines, the Shorts 360-300 version has 1,424 shp (1062 kW) PT6A-67R turboprops with six-bladed propellers and other refinements to produce about 18 per cent more thrust at take-off.

164 examples were sold up until 1991.

Short SD3-30 / 330 / C-23 Sherpa

330-200

The prototype of the Shorts SD3-30 30-passenger unpressurized commuter airliner; later redesignated Shorts 330, was derived from the smaller Skyvan, with a fuselage stretched to accommodate 30 passengers while retaining the Skyvan’s twin tail fin, but including a semi-retractable undercarriage.

Short SD3-30 / 330 Article

The Short SD3-30 prototype (G-BSBH), a 30-passenger airliner powered by twin turboprop engines, was flown for the first time at Belfast, Northern Ireland on 22 August 1974, and the first entered service with the Canadian airline Time Air on 24 August 1976, although the first order had been placed by Command Airways of Pouglikeepsie, New York.

Versions available included the standard 330-200, the Sherpa civil freighter, and the 330-UTT utility tactical transport.

The USAF operated 18 twin-turboprop Sherpa/330-UTT from Zweibrucken in West Germany, providing a distribution service for high-priority spares in Europe. Designated C-23A, the aircraft were ordered in March 1984 to fulfil the European Distribution System Aircraft (EDSA) requirement. Two Sherpas were delivered in November 1984, and the remaining 16 by the end of 1985.

The C-23A is a freighter version of the Shorts 330-200, retaining many features of the civilian model including the forward freight door. An hydraulically operated rear cargo door/ramp is incorporated in the Sherpa, thus allowing through loading. Up to seven C08 or four LD3 cargo containers or two half-ton vehicles can be accommodated, and utility passenger operations may also be undertaken. The C-23A first flew on August 6, 1984, and is powered by two 893kW Pratt & Whitney Canada PYT6A-45R turboprops.

Designated C-23B, the first of 10 Shorts Super Sherpas for the US Army National Guard made its first flight in 1990. The aircraft are similar to the 18 C-23A Sherpas used by the US Air Force, but have more powerful Pratt & Whitney Canada PT6A-65AR turboprops, strengthened wings, five-bladed propellers and air-operable rear freight doors for supply dropping.

Lacking the rear loading ramp of the Sherpa, the Shorts 330-UTT (Utility Tactical Trans¬port) can carry a maximum payload of 3,630kg. Typical loads include 33 troops, 30 paratroops, or 15 stretchers. Range with 30 fully armed troops is greater than 1,100km. Two inward opening rear side doors are provided for para¬dropping. Customers for the 330-UTT include the Royal Thai Army and Royal Thai Police.

Nearly 100 had been delivered by 1990, and a total of 141 Short 330s were built before production ended in 1992.
