Thanks guys, unfortunately this happened yesterday but at least it looks like it can be repaired. Happened well after I had left for the day.

BREAKING: A-26 Warbird Suffers Gear Collapse, Damage at Oshkosh

Great photos Paul, shame about the A-26 though..

Great shots Paul! Shame about the A-26 though.

I have always wondered if the engines are trashed after prop damage like that....

Not always Capt Vick, depends on if there's any physical damage visible on the engine. Obviously inspections are done and the engines are likely to undergo overhaul - certainly for a warbird restoration. If the aircraft has a serious crash the props will be scrapped entirely; no components, regardless if they pass inspection criteria, will be reused - the entire prop will be rendered unserviceable. In this case the props could be used again, that is if the blades aren't bent too far and there's no cracking damage to the hub - I've seen these Ham Std blades bent pretty severely, but returned to service because they can be bent back, believe it or not. The primary consideration for prop blades is overall width and thickness measurements. Nicks can be filed out and the individual blades are scurfed (ground and reprofiled by hand) to clean up their exterior finish. Hubs and metal linkages will be NDT'ed for cracks, so its likely these will go back into service after overhaul.

Shame about the Invader, but great pics Paul, and a heck of a lot of aircraft. Keep 'em coming ....

 

[Wayne Little]

Jesus Paul, you've taken a fantastic series of pics mate..

Thank you sir!

The engines of this aircraft will most definitely have to be completely overhauled. The pilot is on a nose down cruise approach, a good possibility to try and use gravity to bring the nose gear into lock. To maintain this he need some throttle input to keep as close to level flight as he can while the nose is down. You can see his last option of pulling the nose up as high as he can as the mains hit, further using kinetic energy to thrust the gear forward. Unfortunately the gear appears to never be locked. Being round motors the energy transmitted to the crankshaft, gearbox, cams etc. will make damage very likely. As for the props, looking at the tips, it is doubtful they will pass the max bend allowable, the hubs will definitely need to be crack tested. One thinks that under this condition and per the manuals, replacement will be mandatory. Good to see all safe and well, the aircraft, an expensive bill coming up.

Fantastic pictures Paul!!
