Boeing Stearman Model 75, part five. The Stearman in America, part two. Canadian, Colombian, Cuban and Dominican users

 

The Boeing Stearman PT-13/17 Kaydet is an American double winged two-seater basic trainer that was developed during the 1930s and was exported to various countries around the world, among them, the following ones:

• Canada: The first Canadian user of the Stearman was Trans-Canada Airlines, which bought three Model 73 (PT-13) in 1937 and used them for surveying new routes and pilot training. They were employed until two years later, 1939 and sold soon later.
  However, the most known Canadian usage of the Kaydet was the Royal Canadian Air Force (RCAF), which employed three-hundred PT-17 (locally known as PT-27) bought by the Royal Air Force (RAF) under the British Commonwealth Air Training Plan in spring 1942. The Stearmans were to be used by the No. 3 Flying Instructors' School in Arnprior, Ontario and four additional elementary flying schools in the Canadian prairies. 
  However, they were initially delivered without winter and night-flying equipment (an enclosed canopy) and in November 1942 they were returned to the United States Army Air Force in exchange for the Fairchild Cornell. 
  Other RCAF's units which used the Kaydet were Test and Development Establishment of the RCAF and No. 36 Elementary Flying Training School in Alberta. 
  
  
• Colombia: In 1942 the Colombian Air Force (CAF) acquired an unknown number of PT-17 Kaydets to employ them at their Military Aviation School as basic trainers. They were employed in this role for many years, until 1954 when they were gradually replaced by the much modern Beech T-34 Mentor. The last PT-17 serving with the CAF was retired in 1957. Many were sold to private aeroclubs and some are fly worthy nowadays.
  
  
• Cuba: The Cuban Army Air Corps (CAAC) bought seven Stearman Model A73B1 (a Model 73 powered by a Wright R-790 Whirlwind engine) which were delivered between July 1939 and March 1940. Later, when the United States entered the war in December 1941, Cuba was sold a total of 48 trainer aircraft as part of a lend-lease system, in order to watch the entrances to the Gulf of Mexico against German U-Boats, as a total of four Cuban merchant ships were sink, killing a total of 56 Cuban sailors. 
  Among those 48 aircraft, were six PT-17s (numbers 38-39-40-41-42 and 43) delivered in July 1942 and three additional N2S-4 (numbered 44-45-46) in June 1943. 
  They all were flown under Aviation School located presumably in Rancho Boyeros. 
  
  
• Dominican Republic: The Dominican Military Aviation Corps employed a total of 25  PT-17s during the 1950s. They were replaced by more modern types such as the Beech T-34 Mentor.

Junkers Ju.52, various American users

 

Preliminary note: This post will be the last one before our mid-winter break. See you back in March!

The Junkers Ju.52 is a German cargo plane that was designed by Ernst Zindel and manufactured by aviation company Junkers. 

It was in production between 1931 and 1952 and, with more than 4.000 aircraft manufactured, the type was exported to various countries all around the globe, among them, the following ones:

• Brazil: The Brazilian airline, "Viaçao Aerea Rio Grandese" (Aerial Aviation of Rio Grande) bought one Ju.52/3m in 1937 which arrived in 1938. It was named "Mauá" and was restricted to aerial routes inside the Brazilian state of Rio Grande do Sul, although the aircraft had capacity for longer routes. This was done because it only flew when the airplane was fully booked. This machine, registered as "PP-VAL" had its capacity increased from 17 to 21 passengers. After a tragic accident close to the city of Porto Alegre where 6 people died on 28th February 1942, the aircraft was declared beyond repair and was written off.
  Another Brazilian operators of the type were :
• Aeronorte: An airline located in Sao Luis, at the state of Maranhao, North-Eastern Brazil which operated one Ju.52/3m rented from VASP -Viaçao Aerea Sao Paulo, Sao Paulo Aerial Aviation- from 1950 until 1951.
• Syndicato Condor/Cruzeiro do Sul: The main Brazilian operator of the Ju.52. Being a subsidiary of Deutsche Lufthansa for South America, this airline had 16 Ju.52/3m bought between 1934 and 1939. The Ju.52/3m was the main workhorse of the company until 1943 when it was converted into Cruzeiro do Sul and the Ju.52/3m were gradually replaced by American Douglas DC-3 transport planes. However, the Ju.52/3m were still serving some routes in 1945 as some of them were equipped with floats in the Amazonian region. 
  They all were either sold to other companies or countries (like Argentina) or scrapped.
• Viaçao Aerea Sao Paulo: This Sao-Paulo based airline had at least two Ju.52/3m in service during the early 1940s. Further details about them are unknown, however one of them was rented to Aeronorte in 1950.
• Canada: Canadian Airways bought the sixth Ju.52 built. This machine, unlike most of the other Ju.52/3m, was powered by a single four-propelled engine, a Rolls Royce Buzzard. It was bought in 1931 and that time it was the largest aircraft present in Canada and could operate on either floats or skis.
  Nicknamed as "The Flying Boxcar" it proved to be an excellent cargo airplane as it could carry loads no other aircraft of the time could thanks, partially to its large roof hatch. 
  In 1942 Canadian Pacific Airlines took over all of Canadian Airways flying stock and in 1947 it was commissioned out of service and sold to a junk dealer which tore it piece by piece with its fuselage ending as a child's playhouse in Winnipeg. Thankfully it was recovered and it's nowadays exposed at the Royal Aviation Museum of Western Canada.
• Colombia: In 1932 the Colombian Army was in war against Peru over the Leticia Region of the Amazon region. It was then when, in order to reinforce the Colombian Military Aviation with bombers that, the Sociedad Colombo-Alemana de Transporte Aéreo (SCADTA - Colombo-German Air Transport Society) bought three which were assigned to commercial flights in the newly created company. When the Leticia Incident (AKA the Colombo-Peruvian War) was waged in September 1932, the three Ju.52/3mde (an ad-hoc version equipped with floats and additional defensive dorsal machine gun hatches) of SCADTA were requisitioned by the Military Aviation which were employed as bombers operating from rivers and lakes as the Colombian Amazon jungle lacked suitable airfields. This became the first operational use of the Ju.52 as a bomber. 
  Shortly after the war, additional three Ju.52/3m were acquired which arrived by ship on 5th July 1933 and were sent straight to the Military Aviation. 
  After the conflict, in 1933, the Junkers were based in the town of Puerto Salgar, at the district of Cundinamarca. One Ju.52/3m registered with the number of "625" was assigned as the personal transport of Colombian president Enrique Olaya Herrera and, on 24th October 1933, it was employed by General Luis Acevedo to fly to Manaus, in Brazil, to sign peace with Peru. 
  One of them crashed on 14th January 1936 killing all its passengers, making this unfortunate event the only fatal accident of a Colombian Ju.52. 
  The Ju.52 was employed as the main transport of the Colombian Military Aviation and, just like Argentina, it was the first aircraft that Colombian paratroopers used for their first airdrops during a manoeuvres that took place at the Base Aérea in Madrid, in Cundinamarca district, on 13th May 1947. Three years after, as more advanced and modern types were bought, the Ju.52 was written off and, given its historical importance, one is exhibited nowadays at the Colombian Air Force's Museum.
