Miles M57
Aerovan IV (c/n 6427) ZK-AWW Was one of two Miles Aerovan aircraft ordered by
the Royal New Zealand Air Force for experimental work in aerial topdressing. It
began its life at the Handley Page plant at Reading in the UK in 1949 as
G-21-3. It went on to become NZ1752 with the Royal New Zealand Air Force. The
two RNZAF Aerovans arrived in New Zealand in November 1949 and January 1950. The
initial plans for NZ1752 to be used for topdressing trials were changed and instead
it was equipped for airborne magnetic survey work in association with the Department
of Science and Industrial Research. It was operated by the Research and
Development Flight which was a part of 41 Squadron based at Whenuapai.

In
November 1950 it was announced that the two RNZAF Aerovans were to be sold. The
Press reported that one has flown 67 hours and the other 103 hours. Soon
after assembly at Rongotai, one machine was fitted with a hopper and carried
out aerial topdressing. The other aircraft was fitted with a magnetometer and
carried out a geothermal survey in the Wairakei-Taupo district. A spokesman at
Air Force Headquarters said that the aircraft had been originally purchased
because no machine in the R.N.Z.A.F. could be economically modified for the
work required. Now they had completed their tasks and there was no further use
for them.
NZ1751
was sold to Airwork (NZ) Ltd of Christchurch becoming ZK-AWV on the 16th of
April 1951. NZ1752 was sold to Southland Aerial Fertilisers Ltd of Invercargill
becoming ZK-AWW on the 28th of September 1951. Initially it was used for topdressing but proved unsuitable for this type of work. Subsequently it was converted by Airwork (NZ) Ltd for passenger and freight work with a 10-seat
cabin.

On the 4th of March
1952 the Press reported that The first large scale freight-dropping flight
to South Westland took place this morning when a Miles Aerovan, "The
Flying Boxcar," left Hokitika early today with sections of huts destined
for the use of campers and mountaineers in the Franz Josef and Almer Glacier
regions. The huts - in prefabricated sections - were dropped by parachute in
drops of 12 sections at a time. The plane, piloted by C. W. (Bill) Hewett, of
Mossburn, with Andy Hindmarsh as assistant pilot, circled the area, which was
pinpointed by smoke signals from guides attached to the hostel. The aircraft is
capable of carrying loads of up to one ton and has been used for all purpose
freight and passenger work throughout the country. Its operations have extended
from aerial topdressing in the Canterbury area, to running fruit and produce,
between Nelson and Roxburgh; light cars have also been carried with ease by the
aircraft.
The work carried, out to-day is part of a
Government contract and is expected to be maintained for a period of a week -
given favourable weather. The loads today weighed in the region of 1000 lb and
each section has one parachute attached. A static line - a similar arrangement
as is used by paratroopers - is hooked inside the aircraft; part of the rear
fuselage is removed and the bundles are then pushed out, the static line
opening the 'chutes automatically. Most of the drops today were made from a
height of between 6000 and 7000 feet, the operation ensuing flying around Mount
Cook prior to each drop. Work on the construction of the huts is expected to
start almost immediately and should prove a boon to sportsmen in South
Westland. Each trip takes a matter of two hours - returning to Hokitika Airport
each time for fresh loads and to refuel. The first flight-originally scheduled
to leave at 6 a.m. was delayed for over four hours because of low cloud and
poor visibility. The first load of the contract, beds, mattresses and fittings,
weighed a little over 1000 lbs.
The Miles Aerovan is of an entirely unorthodox
design and when it first landed here yesterday afternoon attracted considerable
attention. The pilot, Bill Hewett, has had considerable experience in civil
aviation and since the end of the war has logged over 3000 flying hours in
country-wide operations. Prior to its arrival at Hokitika, the plane had been
engaged at Queenstown. Although primarily intended as a general freight
aircraft, it can be adapted in a matter of minutes to a nine seater capacity
passenger plane. It is owned by Airlift Ltd., and its operations range from
passenger charter flights to aerial top-dressing, or it can easily be adapted
as a flying ambulance if necessary.
In 1991 long-term guide at Franz Josef Peter
McCormack talked to South Westland-historian Dorothy Fletcher about the
building of the Almer Hut. Materials for this hut, weighing nearly five
tonnes, were packed to the site by foot. This hut had to be replaced by 1952
because the weight of the snow had burdened the structure. This third Almer Hut
is sited on a more exposed ridge, 200 metres above the site of the old hut. The
site was chosen by guide Harry Ayres. It was' hoped that the wind would play a
bigger part in taking the snow away. Four men did the foundations for the hut.
This required an enormous amount of stone work and rock shifting. Material to
build the hut was air dropped from an Aerovan, piloted by Bill Hewett. The
material was in bundles and each had a big parachute. Very little was broken or
went missing. Building the hut began in March 1952 and was completed by the end
of 1953.
On the 25th of March 1952 disaster struck the
company at Franz Josef. The Press reported that a Miles Aerovan aircraft
owned by Airlift (Southland), Ltd., was seriously damaged when it was on the
ground by high winds at Waiho, South Westland, on Tuesday. The craft, piloted
by Mr W. Hewett, of Mossburn, had been dropping equipment for the erection of
huts in South Westland area, under a Ministry of Works contract. Extensive
structural damage to the machine included a broken propeller and damaged tail
plane and fuselage. Although no wind velocity figures are available for that
area gusts in Hokitika reached speeds of between 55 and 65 miles an hour.

In early May 1952 it was reported that the
Aerovan was being repaired using parts salvaged from Airwork’s Aerovan ZK-AWV which
also had been overturned in high winds at Wellington in 1951.
The work on ZK-AWW was completed by the end of
the year and on the 11th of December 1952 the Press reported that, Rebuilt from the fuselage of one aircraft and the wings of another, a Miles Aerovan freighter will be used this week to drop materials for the construction of the new Mueller Hut in the Mount Cook region. The aircraft, which was assembled at Harewood by Airwork (N.Z.), Ltd., was flown to the West Coast by Mr C. W. Hewett on Tuesday. Nine months ago, Mr Hewett was engaged in dropping materials for mountain huts which are being built by the Ministry of Works for the Tourist and Publicity Department. After dropping material for the Aimer Hut, which overlooks the Fox Glacier, he started a similar task in the region of the Mueller Glacier, where the old hut had been destroyed by an avalance. While the Aerovan was on the aerodrome at Waiho it was caught by a strong wind, blown over, and badly damaged.
When the damaged aircraft was brought to Christchurch, it was found that only the wings could be used. Another Miles Aerovan owned by Airwork (N.Z.), Ltd., was therefore “cannibalised” as was frequently done when tanks and vehicles were repaired during the Second World War. The second Aerovan had been badly damaged in an accident at Rongotai, and only the fuselage could be used. There was some delay in the building of the new aircraft from the remains of the two, as essential parts had to be obtained from England.

On the 27th of February 1954 the new aerodrome
was opened at Roxburgh. The Christchurch Press of that day reported, Today
the Minister in charge of Civil Aviation (Mr T. L. MacDonald) will officially
open New Zealand’s newest airport at Roxburgh. The 1450 yard airstrip, placed
midway between the hydro works and Roxburgh township, is the longest airstrip
in inland Otago and Southland, and the largest privately-owned aerodrome in New
Zealand. Douglas airliners chartered from Dunedin and Christchurch will carry
visitors to the opening ceremony and its attendant aerial field day, organised
by the Roxburgh Aero Club. Capable of handling aircraft as big as Bristol
Freighters and Douglas DC3’s, the Roxburgh airstrip will be of considerable
value to fruit growers of the surrounding region. With Bristol Freighters and,
possibly, a Miles Aerovan owned by Southland Aerial Fertilisers, Ltd., which
has developed the air strip, fruit growers will be able to send their produce
to the rest of New Zealand much faster than in previous years.
In addition to the Aerovan, Southland Aerial Fertilisers
will operate an Auster for unscheduled passenger and scenic flights, and five
DH82’s for topdressing. Until hangars and passenger facilities are built the
company will continue to use Mossbum, 30 minutes’ flying time away, as its
headquarters. Work began early in October to bring the Roxburgh landing field,
established by the Roxburgh Aera Club about 20 years ago, to a standard
permitting its use by aircraft such as the 19-ton Bristol Freighters. Before
this most recent effort by the Southland company Ministry of Works men had
levelled a strip 800 yards long, but it was not until October 8 that three
carry-alls began work, forming the airstrip, 1450 yards long and 400 feet wide.
Drainage of the new field is said to be excellent (the base is sand and gravel)
and there is, apparently, no risk of its becoming waterlogged. Surface soil,
removed in levelling operations, was kept and spread our to give a base for
grass. The Roxburgh airfield is 103 miles from Dunedin, and it is considered
likely that it could serve as an emergency landing field if Taieri and its
present alternative field at Hildethorpe, 90 miles from Dunedin, were fogbound.
The day before the opening, on the 26th of
February 1954, Bill Hewett was flying the Aerovan from Mossburn to Roxburgh but
was unable to land due to fog. Other alternate airfields were not
available and with darkness approaching and low fuel the pilot decided to divert to Ranfurly.
Mervyn Gillick wrote to the Southland Times about the demise of the Aerovan… "On
his approach to the airfield he got a reflection from his lights off wires and
gave both engines full throttle. One
engine ran out of fuel causing the wing to drop, hence the crash landing."
The aircraft was badly damaged and was deemed unrepairable. The wreck was returned to
Christchurch with the fuselage later being used as a caravan.
Hewett Aviation continued to operate its topdressing business until February 1967 when it was taken over by Rural Aviation (1963) Ltd.
