Even better... they still have the whole wing tip assembly so they don't have to fabricate a new one.

Good show once again!

Yeah I thought it separated completely from the wing and ended up in someone's backyard!

I was fortunate enough to see this aircraft flying at a show 2 summers ago. To say it looked and sounded incredible would be an understatement !!

Just got home from a work shift in the Arctic. I've had this nagging voice in my head telling me I had read something about this happening on Lancaster and York aircraft in the (long) past. So I pulled my York library and found Technical Service Bulletin No.71 that describes this exact occurrence with "embarrassing but fortunately not serious results"! The bulletin is from April 1955. Subsequently Avro came up with Civil Modifications 38 and 39 (York) which are equally applicable to Lancaster aircraft according to the bulletin.
So it seems this isn't a new thing with the Lancaster mainplane and was known loooooonnnnnggggg ago!
Just throwing that out there!

Wouldn't mind seeing that HercRat. Any way to show us the highlights?

[hercrat]

Sure can......I can scan it and PM it to you or this forum later today!

Here are the scans of the Avro Service Bulletin No.71 and also scans from the "York Aircraft Servicing ans General Notes" regarding wingtips. The publications were formerly of the Transair technical library and provide an interesting insight as to the difficulty they experienced keeping the York going especially with mainplane corrosion problems behind the engines. Haven't posted pics in a while so I hope these come out!
