pmccarthy Posted September 7, 2018 Share Posted September 7, 2018 How sad. But hardly an RAA investigation for a Yak 9. That's a CASA job. 3 Link to comment Share on other sites More sharing options...
biggles Posted September 7, 2018 Share Posted September 7, 2018 “ The Australian Transport Safety Bureau the accident, which involved a single-engine Yakovlev Yak-9UM Warbird. “Initial information provided to the ATSB indicates the aircraft has collided with terrain approximately 20km west of Latrobe Valley Regional Airport,” an ATSB statement said. Five transport safety investigators from Brisbane and Canberra are heading to the scene to collect evidence. The ATSB said they would examine the wreckage, interview witnesses, and collect any available recorded data for analysis.” Yep , looks like they’ve finally got it right ......

kaz3g Posted September 7, 2018 Share Posted September 7, 2018 Had a rebuild atTyabb after nosing over on soft grass runway 12 months ago. Sold to new owner in February. Very sad for family and friends of pilot. A magnificent warbird lost. Kaz Link to comment Share on other sites More sharing options...
ISA Posted September 7, 2018 Share Posted September 7, 2018 Oh how tragic, we all feel it when a fellow aviator leaves the living world under tragic circumstances. May the family eventually find peace in the fact he passed over doing what he loved. RIP Link to comment Share on other sites More sharing options...

old man emu Posted September 8, 2018 Share Posted September 8, 2018 Looking at the displacement of objects that were on the ground before the impact, and the resting place of the aircraft debris, would you suggest that the aircraft was in an inverted spin, with low forward speed when it hit something out of frame to the top right of the picture? 1 Link to comment Share on other sites More sharing options...

Old Koreelah Posted September 8, 2018 Share Posted September 8, 2018 The Yak-9 is a speed machine; small, tapering wings and 170 kts over the fence. Link to comment Share on other sites More sharing options...
facthunter Posted September 9, 2018 Share Posted September 9, 2018 170 KNOT's ? That seems a bit over the top. Sure it's not KM's? Russia is Metric. Nev 1 Link to comment Share on other sites More sharing options...
Old Koreelah Posted September 9, 2018 Share Posted September 9, 2018 I agree Nev, but that number came from the commentary at Narromine provided by the wife of the previous owner. This site Yak-3/Yak-9 specifications quotes 150km/h stall, so I guess over the fence would be at least 200km/h. Link to comment Share on other sites More sharing options...

facthunter Posted September 9, 2018 Share Posted September 9, 2018 Stall speed with flaps is given as 81 MPH (70.5 knots) so just over 100 knots would be fine over the fence, Same as a Mustang, more or less.. 730 metres landing roll. All seems fairly what one would expect. Some commentary is over dramatic with this stuff.. Nev 2 Link to comment Share on other sites More sharing options...
Mike Borgelt Posted September 9, 2018 Share Posted September 9, 2018 Perhaps stall spin while attempting forced landing after engine failure? 170 knots would be fine for a Mirage. 1 Link to comment Share on other sites More sharing options...
ISA Posted September 9, 2018 Share Posted September 9, 2018 Doing some research Vs X 1.3 would be around 91 kts. Call it 100 on App, 95 over the fence. Still quick enough. Those figures are based on MTOW, not likely in most cases on Ldg. Great looking aircraft, such a shame and utterly tragic. Hope the family know that there are aviators out there thinking of them in their time of need -:( Link to comment Share on other sites More sharing options...
Mike Borgelt Posted September 9, 2018 Share Posted September 9, 2018 There is a reason certified single engines aircraft have a 61 Kt stall speed limit in landing configuration. During WW2 there was plenty of data available on forced landings and when the survival rate vs stall speed was plotted there was a "knee" in the curve at 61 knots. Pilot survival then decreases rapidly as stall speed increases. This does limit the cruise performance of single engine aircraft as the wing is too large for efficient cruise. Fighters do not have this limit as it was all about performance to kill the enemy. Pilot survival was not a particular consideration as there were plenty more people wanting to be fighter pilots. Yes, the military does think like that, particularly in wartime. You could also bail out instead if high enough. For the last 30 years or so western militaries have been bombing 3rd world peasants and suffering low attrition. Going up against a near peer adversary will result in horrendous casualty rates. I wonder if the pilot had a parachute and how high he was? These WW2 warbirds were flown by pilots wearing parachutes ( see the recent Grumman Avenger crash in Arizona where the guys bailed out and lived). If you are in the forces they are happy as they get a trained pilot back and the taxpayer buys another aircraft. If you own the aircraft there is a chance you can land it successfully with minimal or repairable damage. If you bail out it is a writeoff. If you are not wearing a parachute you must land it. Nasty choices. Link to comment Share on other sites More sharing options...
