Over several months aircraft production was refined into a 10 stage procedure;
(1) Aircraft arrives on station.
(2) To receipt park - loose equipment removed except when aircraft arc in sealed crates or Eronell (protective covering which ‘embalmed’ aircraft for open storage or transport as deck cargo).
(3) Preparation of Servicing and Inspection Forms by the Inspection Section.
(4) Aircraft is allotted to a hangar for production – entry to the hanger was staggered in order to avoid having two aircraft reach the sane stage at the same tine. A system approach ensured that Gunnery, Radio and Electrical sections worked on each aircraft in turn, and at stages where this work would not interfere with the Airframes and Engine ratings. Available modifications were incorporated during erection or inspection.
(5) Aircraft arrives at the end of hangar line for gun alignment, and final check by inspection team; during this final check an aircraft moves out of the hanger engine running.
(6) Move to Stop butts for gun firing and harmonisation.
(7) Move Compass base – if an aircraft carries Radar it goes to Radar Base before the Stop butts, (Avengers are not Butt tested).
(8) Check Test Flight,
(9) To Storage - Category "B".
(10) Transferred to Storage - Category ''A" when loose equipment is available and the aircraft has been doped.

The output levels achieved fell well short of the production programme, partly due to a lack of airframes being delivered, and partly by the state in which crated or preserved airframes arrived on the station. Aircraft were received in varying states of equipment installation, some arriving completely installed, others partially installed and in many instances completely void of all equipment, in these cases it has been despatched separately and may not arrive with the airframe. In the case of aircraft arriving with equipment installed, it was found that in the majority of cases all the equipment was in first class condition, requiring only a minimum of work to complete the testing and final installation of the aircraft. Aircraft which were only partly installed (and in some oases only partly modified) caused serious delays owing to a lack of spare equipment. Considerable delay was also experienced due to aircraft arriving minus their entire radio equipment.

Being installed at an operational aerodrome none of the mobile Flying Control equipment supplied for MOONAB II was used, however YHF/DF, YG and JG Beacons and ground W/T installations were installed. MONAB II suffered from a serious shortage of M/T spares, Spare parts issued in England were in the majority not required and those required had to be purchased where possible from local sources. Additionally no spare parts were issued for Fordson 15 cwts.

The personnel of 723 Squadron arrived from RNAS Nowra, MONAB I, on 28th February to commission as a Fleet Requirements Unit and receive their initial equipment issue of 8 Martinet TT.I and 8 Corsair II aircraft (the aircraft assembled by the advance party). The squadron was also temporarily issued with 2 Expediter passenger aircraft in order to initiate a communications flight prior to the arrival of 724 Squadron which was to operate as a dedicated communications flight.

724 Squadron commissioned at Bankstown on 10th April 1945 to carry out communications duties. Initial equipment was 2 Expediter Is {from 723} & 2 Anson Is.

723 FRU moved to Jervis Bay on 1st May 1945 to begin operations as a Fleet Requirements Unit. On the14th 1830 & 1833 squadrons disembarked their Corsair IIs from HMS Illustrious; 1833's personnel re-embarked the same day, their aircraft being retained at Bankstown. 1830 squadron re-embarked in Illustrious for passage to UK on May 24th.
 

A royal visit was made to the station on June 1st as Prince Henry, Duke of Gloucester, the Governor-General of Australia, toured the facility.  Whilst there he test fired a Browning 50 calibre aircraft machine gun at the test butts. The prince signed the gun's log book 'Henry' [but signed in the wrong place] the log was later raffled and was won by AM(O) 'Jimmy' Dixey.


'A' Flt 1701 A.S.R. Squadron's Sea Otters moved here from RNAS Maryborough for detached duties on July 24th, returning to Maryborough August 7th. On August 23rd the recently disbanded 1834 & 1836 Squadrons aircraft were delivered from HMS Victorious, via Maryborough, for disposal.

'A' Flt 1701 A.S.R. squadron arrived from Maryborough for detached duties on October 15th, returning to Maryborough on the 21st.

MONAB II and HMS NABBERLEY paid off at Bankstown on March 31st 1946, the station returned to R.A.A.F control. 724 Communications squadron moved to RNAS Schofields, MONAB VI, to continue operations.

By the war’s end Bankstown had carried out 2,500 Test Flights with only four major accidents (one complete loss and three major damages); three other accidents were due to the soft state of the airfield resulting in aircraft nosing up either after landing or whilst taxiing.

Remembering Bankstown:

 

"As you might expect, every piece of equipment in the aircraft was checked - radio, guns, hydraulics, engine performance, and handling characteristics. I normally took my observer and air gunner with me on all test flights, even when I was doing stalls with and without flaps, and diving to maximum permissible speed. It was during the last manoeuvre that a couple of incidents occurred that made me change my normal procedure.


If my memory is correct, the maximum permissible diving speed (as per the handbook) was 320 knots. The maximum speed we were obliged to attain during test flight was 310k. However, since I was fully aware that front line squadrons frequently achieved speeds of up to 350k I saw no reason why I should pass an aircraft as being fit for operational service unless I had also flown It to this speed.


The first two months passed uneventfully, but one afternoon, just as I was approaching 350k in a dive, part of the skin on the upper surface of the wing started to fold back, creating some minor turbulence. From then on I took off by myself to do the stalls and dive to maximum speed, after which I landed again to take on my crew to complete the rest of the test schedule. It was just as well that I did, for on one occasion, just as I was approaching 350k in a dive the aircraft went completely out of control with my body being thrown around the cockpit and the control column belting me in the knees.


At first I thought it was about time I baled out, but then I grabbed the violently oscillating control column and found that I could get the aircraft more or less under control. The elevator control seemed rather sluggish but the other controls were fairly normal so I decided to come in for a landing. This was achieved without too much difficulty and after taxying to the tarmac and getting out of the aircraft I saw only too plainly what had happened. Most of my starboard elevator had broken away during the dive. This incident did not change my determination to push the aircraft up to 350k - the only difference being that I now started the dive from 12000 ft instead of 10000."
