XT131 – Bell Sioux

XT131 - The Bell Sioux The AHAF’s ‘clockwork mouse’ is from the first batch of fifty ordered by the AAC and was built by Agusta Spa at Gallerate in Italy in 1964.

These aircraft were ordered as stop-gaps for the Westland-built Sioux which started coming off the Yeovil production line in the Spring of 1965. The civil equivalent to the Agusta-built Sioux is Agusta-Bell 47G-3B-1.
XT 131 was taken on charge by the AAC at Middle Wallop on 3 July 1964 and for the duration of her military service was used for flying training and engineering familiarisation at Middle Wallop.

She was transferred to the Development and Trials Flight on 18 November 1977 until officially transferred to the AHAF on 11 September 1980.
The Sioux is probably the best known of military helicopters, especially after the success of the film, and then the television series ‘MASH’.
