Yes this is bad news!!
Very unlikely to be serviceable for Dunsfold either. We have been lucky to see XH558 twice this year, and will be going up to Doncaster at the end of October for the Members Day. Otherwise "completely gutted" would be how I would be feeling now!
But it is a 60 year old plane required to be maintained to modern aviation standards, and it's serviceability this year has been excellent, so can't grumble really.
