FAA, which acquired its first example in June
- Grumman was selected by NASA
to construct lunar modules for America’s
space programme and the company fitted a
Gulfstream with a cargo door and used it to
transport some of the assemblies.
The US Navy and the US Marine Corps
utilised a total of nine examples under the
designation TC-4C Academe for training
bombardiers and navigators destined for
the Grumman A-6 Intruder aircraft. This
variant first flew in 1967 and was fitted with
an Intruder nose radome in place of the
aircraft’s normal nose profile.
A single Gulfstream was acquired by the
US Coast Guard for operation as a VC-4A
VIP transport.
When production of turboprop-powered
Gulfstreams ceased in February 1969,
exactly 200 examples had been built.
The last production aircraft was delivered
as N750G to the New York-based IT &
T Corporation in June of that year, but
the airframe was still judged capable of
development.
STRETCHED VARIANT
In 1978, the Gulfstream American (later to
become Gulfstream Aerospace) Corporation
acquired the rights to the Gulfstream I
design from Grumman and set about
producing a longer version for the commuter
airline industry.
The existing airframe was modified
to incorporate a 128in (325cm) fuselage
stretch, to carry up to 38 passengers plus
baggage.
The Rolls-Royce Dart powerplants were
retained, and the modified aircraft was
initially designated as the G-159 Gulfstream
1-C, later amended to the G-159C
Gulfstream. It was also briefly called the
Commuter for marketing purposes.
The first converted aircraft flew in this
form for the first time on October 25, 1979,
and certification followed a year later.
The G-159C offered potential operators
a maximum cruise speed of 345mph
(555km/h) at 30,000ft, and a range with
maximum payload of 500 miles (805km),
but it did not attract much interest. Just five
conversions were carried out, the modified
aircraft being delivered from November
1980 onwards to US commuter carriers
such as Air North and Chaparall Airlines,
whose examples flew in American Eagle
livery under a franchise agreement with
American Airlines.
In September 1982, General Electric
adapted one of its corporate Gulfstream
Is for a programme of 23 test flights of its
CT7 turboprop engine, being developed
then to power the CASA Nurtano and Saab
340 transport aircraft. One of the General
Electric powerplants, coupled with a Dowty
all-composite, four-bladed propeller, was
mounted on the left wing in place of the
usual Rolls-Royce Dart, and 39 flight hours
were logged in this configuration.
In the UK, Gulfstream Is were used as
corporate aircraft by both the Ford Motor
Company and Shell Aircraft, and pre-owned
examples found a new role with several
British airlines in the latter half of the 1980s.
Aberdeen-based Peregrine Air Services
acquired two from the USA, originally
for oil-related charter work and later on
domestic flights on behalf of British Airways.
The failure of the Scottish city’s Air Ecosse
in 1987 opened up an opportunity for the
airline to take over scheduled routes from
Aberdeen to Edinburgh, East Midlands and
Manchester, and to operate Gulfstream Is
on them as Aberdeen Airways. The airline
