Anson Restoration Project 

By Colin Ainsworth, Project Leader 
30 November, 2005

The past month has seen Ernie Killen and Mike Dandurand complete the installation of all the windows and escape hatches in the Anson's cabin. Chuck Calder and Jerry Aucoin finally figured out how to install and adjust the rudder cables and linkages that run from the pilots control pedals to the aircraft rudder assembly This installation seemed a very straightforward project, however, not having all the manufacturing drawings the installation became very complex.

The two pulley wheels in the bracket are mounted off centre and will only allow the cables to be connected one way, needless to say the first time it was installed it was backwards. The rudder cables then had to be disconnected, the bracket removed and reversed, then the rudder cables rerouted through the turnbuckles and reconnected to the pilots rudder pedals. The lack of drawings has plagued us on this project since we started, mind you it just adds to the fun.

A few weeks ago while Chuck Calder was in Winnipeg he managed to drive down to visit the museum in Brandon, Manitoba who have already restored an Anson Mk2. While Chuck was there he visited a number of Ansons that are stored outside in various stages of disrepair and was fortunate to obtain a few of the items that we require to complete our restoration. Some of the items were: the main cabin door complete with all the mounting fixtures; a pilot/radio operators seat; parachute stowage assembly and a throttle control assembly pedestal plus many other pieces.

Peter Miller and Keith Brenson have been helping Al Sheppard make up the remaining electrical wire bundles; once these are done they will be installed and connected at various locations in the aircraft.

This past Monday we were again fortunate to have twelve veterans visit us. We really enjoy their visit. Don Neily was a pilot instructor during WW II and used to fly the Anson, so he is a source of information to us, and tells us what it was like to fly the Anson. 

Next month hopefully the cabin door will be completed and installed and the wing fillets returned to us from 14 Wing workshops.

 This month's "Anson Trivia" is about the Anson's development prior to WW II.

 The following is from Flypast Magazine July 1989 Page 55 by Ken Wixey.

 Although famous as a World War Two military aircraft, the Avro Anson owed its origins to a pre-war civil design. Having constructed Fokker F.V11B/3 trimotor passenger aircraft under license as their Type 618 Ten, Avro had to rethink on design and production methods. A scaled-down 618 Ten, the 619 was built as a new design followed by a larger version, the 624, but in 1934 the 642/2 and 624/4 emerged as much refined aircraft.

Experience with such types induced Avro to respond to an Imperial Airways specification in which a four passenger, twin-engined monoplane for use on charter flights was required. Roy Chadwick, Avro's chief designer, produced the Type 652, a low-wing monoplane with a retractable landing gear, and two Armstrong Siddley Cheetah V engines. An order for two Avro Type 652 placed in April resulted in the prototype,

G-ACRM Avalon, making its initial flight on January 7, 1935.

Meanwhile in 1934 the Air Ministry had been seeking a new twin-engined coastal reconnaissance and patrol land-plane, Avro quickly responded with their Type 652A which closely resembled the 652. Another contender came from de Havilland with a "militarised" version of the DH.89 Dragon Rapide designated DH.89M.

Both designs were selected by the Ministry for prototype development and a contract drawn up. It was stipulated delivery of prototypes must be by March 1935, which gave Avro less than six-months to complete detailed design work and construct a prototype based on a civil type which itself had not flown!

External visible changes to the military 652A included replacement of the civil aircraft's porthole windows by three of rectangular style and installation in a dorsal position of an Armstrong Whitworth turret housing a single .303-in Lewis machine-gun. This turret not only provided a defensive gun position, but also an ideal vantage point for reconnaissance duties. It was a 1933 design in which the combined weight of the gunner and his seat was balanced against the weight of the gun.

A .303-in Vickers machine-gun was housed on the port side of the nose firing through a fairing. It was fixed to fire forward and operated by the pilot.

 Next month we will continue this article on the development of the Avro Anson.
