Sadly this Flizer ended up inverted at Lossimouth last week.
Clearly, in the photo there are plenty of bods to lift up the wee thing, but what is the best way? If you push up and rotate round the prop hub, that will strain the crankshaft.
Or maybe lift up by the wings and spin it over, with the nose off the ground, but will that damage the spars? A crane and sling would be the best way perhaps, but is not neccesarily available.
T’would be a shame to cause more damage in the recovery than the incident.

This is now for sale as a ‘winter-rebuild’ project on TheHangar website.
Hope to see it around next season.

My best guess is to take it back the way it came, via the nose.
If the wing roots can be supported to take the load off the engine mounts, so much the better.
Once the tail gets past the vertical, the rear fuselage needs supporting. There have been cases of broken fuselages and bent metal longerons from the tail being allowed to crash to earth.
Assuming it wasn’t on full power and it merely shattered a wooden prop, a full shockload strip on the engine may not be necessary. A crankshaft runout test and close inspection of the crankcase for cracks may be sufficient.
I’d guess though that they will need to closely check the tubular steel engine mountings. They are normally designed to take loads via tension, or the vertical load when static, rather than the weight of the whole aeroplane in compression.
I guess the fin and rudder are history and again the rear fuselage and cabane struts will have taken some unusual loads, not in their normal stressing!
Very sad, but its not the first Flitzer to suffer this fate and they’ve all made it back into the air again!

If the prop was turning under power when it dug in and that stopped the engine then you are in to a ‘shock loading’ strip down anyway.
Flipping it over with the prop stopped will not add to your woes.

Unfortunate result there.
Pushing her back over via the nose would probably be the way she arrived that way up in the first place so surely any damage would already have been done?
Should think Lossie had a big crane/lifter & strops to pick her up with.
