FWIW, there is another EASA Emergency AD (2010-0160-E) that updates
and supersedes the June Emergency AD. I don't know what the
differences are. Whether by accident or not the US AD seems to less
restrictive. To paraphrase(always dangerous)it 1)limits aerobatics
2)mandates inspection for crack with a 10x magnifier 3)grounds the
glider if cracks are found 4)requires certain information be forwarded
to the certificate holder w/i ten days of the inspection. It doesn't
say anything about grounding if certain ratios are exceeded or if
records are incomplete or missing(as does 2010-0160-E). Am I mis-
reading this?
