Overview
China National Aviation Corporation, commonly known as CNAC, was one of the foundational airlines of Chinese civil aviation. Established by the Executive Yuan of the Nationalist government in 1929, it was created to develop scheduled airmail and passenger routes linking major Chinese treaty ports and administrative centers. Its early operations were shaped by a complicated partnership between the Chinese government and American aviation interests associated with Clement Melville Keys. Political competition, military interference, weak finances, difficult geography and limited infrastructure made the airline’s first years unstable. CNAC emerged in 1930 from the merger of China Airways Federal and the Ministry of Communications’ Shanghai-Chengtu Airways. The restructured company was majority-owned by the Chinese government, while the remaining interest was held through companies connected with Keys. In 1933 that foreign stake was sold to Pan American Airways, giving CNAC an important international aviation partner. William Langhorne Bond served for many years as operations manager and vice-president, helping develop the company’s operating organization. During the Second Sino-Japanese War, CNAC became an important transportation and logistics organization for Nationalist China. It operated routes within China using amphibious aircraft and landplanes, including Douglas Dolphin, DC-2 and DC-3 aircraft. Japanese attacks made civil aviation exceptionally hazardous. The destruction of the CNAC aircraft Kweilin in 1938 is widely identified as the first destruction of a passenger airliner by enemy action. After Japanese pressure disrupted access through French Indochina and the Burma Road was cut, CNAC participated in the air supply system over the eastern Himalayas. Its pilots and crews flew from Assam through the mountain route later known as the Hump to Kunming and other destinations in southwestern China. These flights operated in severe weather, at high altitude and under threat from Japanese forces. The company also played a humanitarian role during the Japanese attack on Hong Kong in December 1941. CNAC crews conducted repeated flights from Kai Tak Airport to Chongqing, evacuating hundreds of people, including prominent Chinese political figures. During the war, the airline was headquartered in India and formed part of the broader Allied air-supply effort, alongside the United States Army Air Forces’ India-China operations. After the war, CNAC returned its headquarters and principal operations to Shanghai. From Longhua Airport it operated services to cities including Beiping, Chongqing and Guangzhou. The company had grown into a large organization with transportation, engineering, medical, food-service and financial departments, as well as extensive employee housing and support facilities. Its postwar fleet included DC-2s, DC-3s and newly acquired DC-4s, including aircraft intended for a Shanghai–San Francisco service. The company’s political position changed decisively during the Chinese Civil War. On 9 November 1949, CNAC managing director Colonel C. Y. Liu and Central Air Transport Corporation general manager Colonel C. L. Chen led unauthorized flights of 12 aircraft from Hong Kong to Communist-controlled China. The aircraft were received in Beijing and Tianjin, while many remaining employees and their families later moved into mainland China. The defection reflected the leaders’ stated belief that the Communist Party would create a unified China. The Nationalist authorities subsequently sold 71 aircraft remaining in Hong Kong to Civil Air Transport after a prolonged legal dispute. CNAC and the related carrier resumed services in 1950, but both were merged into the People’s Aviation Company of China in 1952 and subsequently became part of CAAC Airlines in 1953.
History
The Executive Yuan of the Nationalist government established the Chinese National Aviation Corporation on 5 April 1929 with authorized capital of ten million yuan. Sun Fo became its first chairman, while Minister of Communications Wang Boqun exercised substantial influence over aviation policy. On 17 April, the government contracted Aviation Exploration Inc., an American company associated with Clement Melville Keys, to establish routes and manage operations. Keys created China Airways Federal in June to operate new airmail routes between Canton, Shanghai and Hankou. The undertaking faced opposition from military and provincial authorities that operated competing air services and sought control of airmail revenue. Wang’s Ministry of Communications established Shanghai-Chengtu Airways, creating direct competition on the Shanghai–Hankou route. China Airways Federal nevertheless inaugurated airmail and passenger operations on 21 October 1929. Financial and political pressure soon placed the company near collapse. A negotiated settlement arranged by Max Polin led to the merger of the rival operators on 8 July 1930, forming the reorganized China National Aviation Corporation, commonly called CNAC. The Chinese government held 55 percent and Keys-related interests held 45 percent. The foreign shareholding changed in 1933. After difficulties involving accidents, finances and relations with Chinese officials, Thomas Morgan arranged the sale of the Intercontinent Aviation interest to Pan American Airways. Pan Am placed Harold Bixby in charge of its Far East interests. William Langhorne Bond remained a central operating executive from 1931 through 1948. Between 1937 and 1941 CNAC operated a growing domestic network with Douglas Dolphin amphibians, DC-2s and DC-3s, as well as several Vultee V-1A transports. War with Japan transformed the airline’s role. The Kweilin incident of August 1938, in which a CNAC airliner was attacked and then strafed after landing, demonstrated the extreme danger facing civil aircraft. Another CNAC aircraft, Chungking, was destroyed on the ground by Japanese fighters in October 1940. Japanese pressure on French Indochina and the occupation of Burma progressively closed surface and air links used by the Nationalist government. In 1941 CNAC helped establish the air route over the Himalayas between northeastern India and Kunming. After the Japanese cut the Burma Road, this route became a vital supply corridor. During the war CNAC operated from India, flying equipment, fuel and other supplies into southwestern China. The flights continued through difficult weather, icing, high-altitude terrain and enemy activity from April 1942 until the end of the war. CNAC’s effort was smaller than the overall United States Army Air Forces airlift but formed part of the same India–China logistics system. The airline also conducted emergency evacuation flights during the fall of Hong Kong. On 8–10 December 1941, eight American CNAC pilots and their crews completed 16 sorties from Kai Tak to Chongqing and evacuated 275 people, including Soong Ching-ling and Finance Minister H. H. Kung. The Japanese attack destroyed multiple aircraft at Kai Tak on 8 December. After the war, CNAC moved from India back to Shanghai in 1946, operating from Longhua Airport. It became a large institution with transportation, engineering, medical, catering and finance divisions, employee dormitories and a substantial workforce. Its postwar network included Shanghai, Beiping, Chongqing and Guangzhou, and its fleet included surplus and newly purchased Douglas aircraft, including DC-4s intended for a Shanghai–San Francisco route. The Communist victory on the mainland brought the airline’s independent existence to an end. On 9 November 1949, managing director C. Y. Liu and Central Air Transport Corporation general manager C. L. Chen led 12 aircraft from Hong Kong to Communist-controlled China. The aircraft reached Beijing and Tianjin, while approximately 3,400 employees and family members later relocated by land or sea. The remaining 71 aircraft in Hong Kong were sold to Civil Air Transport by the Nationalist authorities, and delivery followed a lengthy Hong Kong legal case. CNAC and CATC resumed operations in 1950, merged into the People’s Aviation Company of China in May 1952, and became part of CAAC Airlines in June 1953.
