Many years ago I saw A20-502 "BF-O" at the Ballarat Air Museum. But the listing for A20-502 says "Aircraft was destroyed 10/01/46 at Piva. SOC 10/01/46."

The Stuart Wilson "In Australian Service" book for the Wirraway lists A20-502 as "SOC 01/46, extant Ballarat Aviation Museum"

... so I wanted to check if the aircraft at Ballarat is the same one which was destroyed in Piva?

Regards,
Derek

derek,
I don't have records to hand, but I think you saw an aircraft painted up to resemble "A20-502 BF-O".

Also I think this aircraft subsequently crashed. Someone will come up with more precise info.

No, my bad. I was thinking of A20-719 (VH-WRX) which was painted as A20-458, and crashed in 1999 at Nowra.

VH-WRX WEARYWAY WARBIRD Crash mentioned above. Here is the story. I'll imagine that there is a more complete official crash report out there however....

AIRCRAFT ACCIDENT NOWRA AIR DAY 30 MAY 1999
Wirraway-Model CA-16 Mk3 Registration VH-WRX


Bureau of Air Safety investigation report: The pilot was conducting a handling display in a Wirraway aircraft at a civil airshow at the Nowra Naval Air Station. During the turn back towards the crowd at the western end of the airfield, the aircraft was observed to rapidly descend. Although the wings and nose were seen to be placed in a level attitude, the aircraft continued to descend. The aircraft then abruptly pitched nose up and rapidly rolled to the left inverted, before impacting the ground. The pilot and passenger received fatal injuries.

Witnesses at the airshow reported observing the aircraft conducting steep turns, at the end of each flypast, that were in excess of 60 degrees angle of bank. Some of the witnesses who held pilot or air traffic control licenses reported that the aircraft appeared to be flying at a reduced power setting and that it was being buffeted by the wind.

Discussions with a part owner and examination of fuel company records indicated that it was the pilot's normal practice to refuel the aircraft immediately after each flight. However, on this occasion the aircraft was not refuelled after arriving at Nowra. Allowing for the taxi and flight time from Bankstown to Nowra, it was estimated that the aircraft had about 1.5 hours fuel endurance available for the display. The aircraft's weight and balance were calculated to have been within the prescribed limits.

The pilot was appropriately licensed for the flight. Friends and family commented that the pilot was fit and well and looking forward to participating in the display. At the time of the accident, weather conditions were recorded as a west-north-west wind at 21 knots gusting to 33 knots and broken cloud at 6,000 feet. Discussions with naval aviators based at Nowra indicated that the western end of the airfield is subject to mechanical turbulence during a westerly wind.

A retired naval instructor who trained pilots on the aircraft type during its service with the Australian Defence Force commented that the aircraft had some undesirable flying characteristics: if the control column was pulled rapidly towards the pilot while the aircraft was in straight and level flight, it would 'flick' roll uncontrollably; or if the pilot performed a three-point landing with a crosswind, the aircraft would often drop a wing, resulting in wing tip damage. The retired instructor commented that this was most likely due to the wing tip stalling before the wing root. Therefore, towards the end of its service life, strips or wedges were fitted to the centre plane to induce stalling of the wing root before the wing tips. According to the instructor, this measure was partially successful. Pilots who had flown the accident aircraft indicated that these strips were fitted, although the strips were not recovered from the accident site.

A witness who had spoken with the pilot of the accident aircraft at a prior air show commented that the pilot was aware of the stall characteristics of the aircraft.

Although the propeller exhibited damage consistent with substantial power at the time of impact, it was not possible to determine the power setting. An examination of the wreckage indicated that the aircraft was considered to have been capable of normal operation prior to impact.

It is probable that during the final turn in gusting conditions, the aircraft's airspeed decreased to the point where the aircraft began to descend rapidly. The pilot, observing the rapid rate of descent, levelled the wings and attempted to recover the situation. However, realising that the aircraft still had a high rate of descent, the pilot may then have moved the control column rapidly rearwards and thus induced a stall and rapid roll to the left inverted.

I wonder if it was scrapped or the remains are somewhere?

I believe at least some of the remains such as the wing centre-section were recovered and are part of a Wirraway project stored at Caboolture.

Ta, clearly there are plenty of CAC Wirraway projects around the country then.

Yes there are a number of quite viable airworthy rebuilds around,(these 10 projects below all have the major components required (fuselage, tail, wings, centre-section etc)

A20-99 with HARS, A20-158 with Paul Wheeler, A20-223/601/605 Denis Baxter etc, A20-224 with Matt Grigg (and A20-511/502 currently static), A20-395 with Ian Whitney, A20-656 with Ross Harrison, A20-560/A20-591 with Kent Lee, A20-636 Don Brown, A20-673 Dave Jones.

http://www.warbirdregistry.org/wirraregist...raregistry.html

And that's not counting people with Bare Fuselage Frames and a pocket of dreams.

The limiting factor isn't so much the availability of Wirraway Centre Sections (Guido's Boomerang showed a T6 Centre-section could be used) its the availability of straight trailing edge Wirraway/Ceres wing outers as there are finite sets remaining, (unless someones builds them new).

Equally there is nothing to stop someone building up a "Wirraway" from one of those Bare Fuselage frames and a pocket of cash, and putting a complete T6 wing underneath it and ignoring the swept forward trailing edge, and registering it into Experimental?

(Mind you, if you were to do that it might be worthwhile to build a reproduction Harvard Mk I, at least then you would have something truelly unique, rather than a poor cousin to the real examples, and Mk I Harvards were flown by Australian pilots in EATS schools in Rhodesia.)

Thanks Brenden for that compiled list, however I sold my Wirraway project many years ago to focus on my Wackett Trainer collection, and A20-223 was originally with Bob Mather and may now be with Rob Greinart/HARS as spares for A20-99 although the majority of my parts went to other restorer.
