The Aérospatiale SN 601 Corvette is a French business jet of the early 1970s, Aérospatiale's only venture into that market. Sales were disappointing, and only 40 prototype and production Corvettes were built.[1]

Design and development[edit]

Design work began in the second half of the 1960s as a joint venture between Sud Aviation and Nord Aviation. In January 1968 Sud and Nord decided to proceed with the programme after SNECMA announced it was developing a suitable engine, the M49 Larzac.[2] The SN 600 was first shown to the public as a scale model, on display described as the SN 600 Diplomate at the 1968 Hanover ILA Air Show.[3] It was a conventional design for its class, a low-wing monoplane with turbofan engines mounted in rear fuselage nacelles. The prototype SN 600 first flew on 16 July 1970 with two Pratt & Whitney Canada JT15Ds installed; the Larzac was never fitted to the aircraft as it was still in development over a year[4] after the SN 600 crashed on 23 March 1971.[1]

The first of two prototype[5] SN 601s (by this time called Corvette 100), with a fuselage 3 ft 5½ in (1.05 m) longer than the SN 600's 41 ft 11½ in[6] (12.79 m), flew for the first time on 20 December 1972.[1] In late 1976 Aérospatiale decided to cease production after the company had only received orders for 27 aircraft in the two-and-a-half years following the type's certification (it had hoped to sell six per month).[1][7] Aérospatiale studied a version with a further fuselage stretch to accommodate 18 seats, to be called the Corvette 200, but SN 601 production ended before any had been built.[1]

Operational history[edit]

SN601 Corvette of Sterling Airways at Brussels Airport in 1985

A number of Corvettes sold were used by French regional airlines Air Alsace, Air Alpes, Air Champagne and TAT.[8][9] Sterling Airways of Denmark also operated the type. One Corvette was used as a VIP transport by the Congolese Air Force.[10] As of January 2009 a small number of Corvettes are still active in Europe and Africa, including one (F-GPLA cn 28) in France fitted out for aerial photography.[11][12] This Corvette was used in the TGV high speed test as a chase vehicle/aircraft.

Airbus Industrie used a fleet of five Corvettes for internal transportation from 1981 to 2009.[13]

Variants[edit]

SN 600
The first Corvette prototype, powered by two 2,200 lbf (9.8 kN) thrust Pratt & Whitney Canada JT15D-1 turbofan engines.
SN 601
Production version with longer fuselage than SN 600 and 2,500 lb (11.1 kN) thrust JT15D-4 engines.[14] 39 built, including two prototypes.[1]

Accidents[edit]

Including the prototype SN 600, a total of eight Corvettes are recorded as having been written-off in crashes.[16] The worst loss of life in a Corvette crash was on 3 September 1979, when an SN 601 of Sterling Airways crashed in the Mediterranean Sea off Nice following a double engine failure. All ten occupants were killed.[17]

On March 19, 1998 a Corvette crashed in Portland, Oregon after the pilots decided to take off with only the portside engine running, while the starboard one was inoperational due to a damaged engine starter. Nobody was injured, while the aircraft suffered damage after only a short flight.[18]
