A95-203 RAAF Antarctic Flight in support of Australian National Antarctic Research Flight (A.N.A.R.E). Delivered 23-Sep-1956.

Note: Delivered in overall International Orange scheme and reported with Day-Glo panels on outer wings, rear fuselage, leading edge of tail fin and on tail planes. It wore the Bounding kangaroo fuselage marks and “D” type wing roundels, fin flash, DH logo above it and white “Beaver” marks in script on both pilot doors.

Antarctic Adventures.

The following notes are extracted from the book written by David Wilson, “Alfresco Flight, the RAAF Antarctic Experience”. Details of specific flights are mentioned where details are known but the aircraft flew many other sorties on reconnaissance, photographic and depot support flights as well”. The notes highlight the problems encountered by both the flight and ground crews in the tough environment.

1957-1958 season.

The aircraft was embarked on MV Thala Dan leaving Melbourne on 03-Jan-1958. The flight crew were Ivan Groves, H.O. Wilson, S.A. Manning, G.K. Downer, A.K. Richardson & O. Maquire. The ship arrived at Lewis Islet on 11-Jan-1958 where a weather station was established. It then moved east down the Antarctic coast on the route to Davis Depot, but was impaired by ice. A reconnaissance flight was carried out which resulted in the ship having to steer a reciprocal course out.

A round trip flight of 240 miles was made to the American base at Wilkes on 28-Jan to collect an Australian observer back to the ship, but low cloud and glare made it difficult to find the route. The Americans vectored him in by radar. However on the return flight a wind change of 270 degrees blew the aircraft a long way off course however the Davis radio beacon was used to guide the aircraft back although landing in the near dark provided a difficult sea landing.

The ship arrived at Davis on 04-Feb-1958 and the aircraft completed a flight to the Vestfold Hills and back. The ship arrived at Mawson on 10-Feb and an extension to the Hanger was commenced and improved radio communication mast was erected. A95-203 was converted from floats to ski wheel combination.

Blizzards and failing light in Apr & May-1958 reduced the flying effort and the first major flight was not made until 17 Jul-1958 when a reconnaissance was made to the King Edward VIII Gulf to open the spring programme.

Later the aircraft flew flights to the Masson and David Ranges to locate landing sites for the summer operations.

On 15 Aug Grove with Manning and McLeod commenced a flight to Davis but strong winds and complete cloud cover forced a return to Mawson. However the oil pressure gauge dropped to zero  and grove turned towards the sea  but the mechanical condition of the aircraft meant that he had to land in a heavily crevassed area of sloping ice about 800 yds inland, eight miles west of Scullin Monolith. The aircraft was sliding downhill and only kept still with the engine running until it was secured safely on the ice. The men erected a tent to overnight in and A95-202 piloted by Wilson with engineer Richardson landed close by the next day and took Manning and McLeod back to Mawson. The two men remaining worked on the engine and stayed another night in uncomfortable conditions on the ice. Wilson returned the next day and after a discussion Grove decided to attempt to fly back to Mawson. It arrived back at Mawson safely, just. Richardson completed the engine change by 23-Aug 1958.

On 12-Sep the aircraft was involved in the establishment of fuel depots in the Ygarden group and later in the month the establishment of a sled route from Amundsen Bay to Mawson, a distance of some 400 miles and flights to the Taylor Glacier.

On 10-Dec 1958, Wilson was making a normal approach to land at Mawson when he entered severe turbulence and a 1,500 ft per minute sustained climb was indicated while attempting to descend with the throttle fully closed.

1958-1959 Season.

The director of the Antarctic Division requested that the aircraft be base above Mawson on the plateau as the condition of the ice at the base in summer caused handling problems around the hanger and he felt that the value of continued flying through the summer months justified the risk of leaving the aircraft in the open. The considered reply was that experience showed that in overload conditions the aircraft could not sustain numerous landing and take-offs from rough plateau ice. The suggestion was to use larger twin engine aircraft. The Director reluctantly agreed but the seed was sown for the provision of a Dakota.

In early Apr-1959, A95-203 was tethered down on the plateau behind Mawson for four days between flights no doubt as a trial for the deployment of the aircraft onto the plateau for the summer season Due to the weathering the engine had to be hand cranked to start.

In the winter during early July one of the engineers was found collapsed in the hanger under the aircraft with carbon monoxide poisoning. He had been running the engine inside and the outside blizzard had built up snowdrifts and caused the hanger to be virtually airtight.

During a blizzard lasting from 27-30-Jul 1959 the spare floats and cradles were smashed against the wind fence.

Contact had been lost for several days from the Taylor Glacier party that had been dropped off on 18-Jun and A95-203 was dispatched to find the reason. On arrival at the site there was just a blackened mark on the surface where the sleeping hut had been, but now burnt out. The party were found just in their clothing as worn. The weather for the flight was terrible and the fact that it happened at all was a tribute to the ground and flight crews.

It was then involved in supporting the scientific teams but because of the poor weather the aircraft only completed flights on eight days of September.

On 27-Oct whiteout conditions caused the aircraft with A95-201 to land near Crooked Island 120 miles from Mawson, and had to remain on the ground until the morning of 29-Oct when conditions improved, the crew living on army rations.

On 03-Nov the aircraft was caught in a crosswind gust and the wingtip was damaged and as the cargo was unloaded it was also found that the starboard aileron was fouled. This was freed but subsequent repairs at Mawson took until 11-Nov.

On 22-Nov a faulty polar compass and inadequate maps caused the crew to be uncertain of their position. It managed to return safely but with very little fuel in its tanks.

The period before Xmas was spent establishing a fuel stock at Beaver Lake, obtaining astro fixes and preparing for the New Year operations

On the 28-Dec-1959 three of the crew drove a Weasel up to the plateau behind Mawson where the aircraft were supposedly secure but broke through an ice encrusted melt water stream which delayed arrival at the aircraft. By the time they arrived the moderate wind that had been blowing on the coast at Mawson had increased to a velocity of 80mph. Before the weazel could be driven back to Mawson for assistance A95-203 had torn the heavy railway sleepers, to which it had been tied down, out of the ground and was glissading away, chased by McIntyre and Ball in a D4 tractor. They succeeded in dropping the dozer blade onto one of the torn out anchors to stop it sliding further over the ice. Heavier steel cables and wing tip ropes were used to secure the aircraft. However the wind increased to 120mph and the aircraft broke away again, being blown down the slope. Both main-planes being grotesquely bent and other parts of the aircraft were severely damaged. The men who had been sheltering in an iced in caravan managed to re-secure the now broken aircraft which seemed bent (no pun intended) on self destruction. The wind blew for a further 17 hours before the men could get back to Mawson. The Flight salvaged the remains of the aircraft which were shipped back to Australia on the MV. Magga Dan

Parts from A95-201 & 203 were used to rebuild one aircraft receiving A95-203’s c/n 1052.

Note: Anthony R. Barringer (1925-2009) was a pioneer in the geophysical industry. He made numerous contributions to the development of exploration technology, both in Canada and abroad. His most noteworthy contribution was the development of the INPUT (Induced Pulse Transient) airborne electromagnetic (EM) system. This technology became the premier fixed-wing airborne survey system, and has been credited in the discovery of more than 25 commercial ore deposits with a combined value of tens of billions of dollars.
