The Vickers Type 121 Wibault Scout was a British fighter built by Vickers in the 1920s. It was a licensed version of the French Wibault 7 aircraft, with 26 being sold to Chile in 1926, where they served until 1934.

Design and development

Vickers set up a partnership with the French aircraft manufacturer, Avions Marcel Wibault to exploit the patented system of all-metal construction developed by Wibault. This used corrugated light alloy skin panels, and made for easy maintenance and inspection . As part of this partnership, Vickers placed an order with Wibault for a single Wibault 7, re-engined with a Bristol Jupiter VI radial engine, to act as a prototype for potential licensed production. The Wibault 7, and therefore the Vickers licenced copy, was a single-engine high-wing parasol monoplane.

The prototype, which differed from the standard Wibault 7 by having a new undercarriage and British instruments, was delivered to Britain in February 1926 and was later fitted by Vickers with strengthened wing struts. The durability of the aircraft's all-metal structure, together with promised good altitude performance, attracted the attentions of the Chilean Military Air Service, who after evaluating the prototype, placed an order for 26 aircraft, known as the Vickers Type 121, or Vickers-Wibault Scout.

The first Vickers built Type 121 flew at the end of June 1926, but crashed following an inverted spin on its first flight. This was found to be due to problems with the aircraft's centre of gravity, which were resolved by modifying the tailplane .

Operational history

The first Type 121s were delivered to Chile in November 1926, partly equipping the Groupo Mixto de Aviacix³n 1, with deliveries continuing until October 1927 . Several were lost in accidents, with at least one losing its wing in flight , but it remained in service when the Chilean Air Force was formed from the air components of the Chilean Army and Navy, finally being retired in 1934 .
