The Avro 748 was a small short-range turboprop airliner designed
by Avro in the late 1950s as a replacement for the now-aged DC-3's then
in widespread service as feederliners. |
 |
Avro concentrated on performance,
notably for STOL operations, and found a dedicated market and was eventually
produced to 380 examples, second only to the Vickers Viscount. A larger
development, the BAe ATP, attempted to compete with the de Havilland DASH-8
but saw a limited production run. |
 |
The
original 748 design started in 1958 after the infamous Duncan Sandys 1957
"Defence White Paper" ended most military manned aircraft development
in England, and Avro decided to re-enter the civilian market. The Viscount
had the large end of the short-haul market neatly wrapped up, so Avro decided
to design to a smaller feederliner design to replace the many DC-3's that
were now reaching the end of their lifespan. Avro was not the only company
to see the potential for a DC-3 replacement, and by this point the Fokker
F27 Friendship was well advanced. Avro decided to compete by producing a
design with better short-field performance, allowing it to operate from
smaller airports. |
 |
The
first aircraft flew from Avro's Woodford plant on June 24th, 1960, and two
prototypes quickly proved the type's short field performance. Eighteen 748
Series 1 aircraft were produced, the first for British Skyways Coach-Air
(later known as Dan-Air) but the majority for Aerolíneas Argentinas.
By this point Avro had been merged into the Hawker-Siddeley Group and the
design was known as the HS-748. The Series 2 entered production in 1961 with a higher take-off weight, and were produced to 198 examples, making it one of the most popular post-war British designs. The more powerful Series 2A followed for another 71, along with another 25 Series 2Cs. |
 |
The
RAF ordered a version modified with a T-tail and rear loading door as the
Hawker Siddeley Andover C1, which was also license produced in India by
Hindustan Aeronautics. Hawker Siddeley became part of British Aerospace in the mid-1970s with the Series 2B becoming the main production model. Several large fleets remain active around the world, significantly in India, Canada and the United Kingdom. The ICAO designator as used in flight plans is A748. |

Avro Desenvolvido e construído inicialmente pela Avro (depois Hawker-Siddeley) e mais tarde pela British Aerospace, o HS.748 tem suas origens no esforço da Avro para retornar ao mercado civil durante a década de 50. Lançado como o Avro 748 em 1958, o projeto foi assumido pela Hawker-Siddeley em 1959, quando a Avro tornou-se parte deste grupo. |

O
novo avião realizou seu primeiro vôo em junho de 1960. Um total
de quatro protótipos, dois para testes estáticos, foram usados
no processo de homologação, obtida em dezembro de 1961. Naquele momento o primeiro exemplar de produção (Série 1) já havia sido construído. Equipado com dois motores Rolls Royce Dart Mk.514, entrou em operação com a empresa Skyways em janeiro de 1962. Somente 18 unidades desta série foram construídas: surgiu uma nova versão, conhecida como Série 2. Esta foi mais bem sucedida, gerando as subséries 2A e 2B. |
 |
O
primeiro vôo foi em novembro de 1961. A série 2 diferia da
1 por seus pesos operacionais maiores e motores mais potentes. PANEL |

Versões
militares do HS.748 também foram produzidas, semelhantes aos Série
2B. Tiveram também a parte traseira da fuselagem modifica, com
portas em concha e uma rampa de carregamento: esta versão foi bartizada
como HS. 748 Andover, e sua produção terminou em 1988. O "Avro", como ficou conhecido no Brasil, foi eleito pela Varig como substituto do DC-3. A empresa gaúcha operou um total de 11 aeronaves do modelo entre 1965 e 1976, quando então foram substituídos pelos Boeing 737-200. A FAB ainda opera um esquadrão de aeronaves, em missões de transporte. |
