The place for technical discussions about GA and flying.
Technical discussions about GA only, please.
Thanks Keef - I have a quote of £2600 for the two walkway parts only but I can't find any reference to having to have it done just because some if the corrugated stiffeners on the inside have cracked. Ie nothing damaged or unserviceable externally. One engineer likened it to the cracking of plastic wing tips over years, we all know they do it- so the are stop drilled and monitored- not necessary to replace .
I had mine done a couple of months ago on the annual, exactly the same as yours. Total cost arround £1k from memory, wing not removed but loads of rivets to be set. Both inner and outer panels replaced. £2.6k sounds like a bit of a rip off to me.
Ideally, the wing should be removed as you can't use all solid rivets if you don't. That in itself shouldn't be a major drama. The fuel tank needs to come out too but combine that with the 7 year tanks/spar inspection and that's a bit of a cost saver in the long run.
Wing walks do crack and it is the 'corrugated' bits that go - it's a second skin beneath the actual wing skin. You can't stop drill them and they will only get worse. You soon know when they need doing as the walkway is soft under-foot.
Do both (forward and aft) skins at the same time, no point in just replacing one as the other will go shortly afterwards without fail.
As for the cost - it depends what the £2600 includes - wing off, VAT, same time as Annual, or...?
When we had ours done in 2011 it cost €1617 ex vat - say £1295 ex vat ex labour The cost may have been lowered because we had it done as part of a whole series of jobs - for which the final bill was horrendous
Due to recent budget cuts the light at the end of the tunnel has been turned off.
