As usual. Heres the real story.
A/c was being jacked to investigate ongoing defect for airframe vibes.
Jack was placed under wing, at this point it was then determined jack was un servicable.
Unfortunatly air was applied to the jack,and the regulator failed. In turn the jack started to raise.
The ball of the jack had not been located in the jacking pad, and missed the pad by a few inches and punched up through the wing. The wing spar is ok. Just wing panels, hydraulic lines and drive units took all the pain.
The delay in the repair was waiting for Airbus to come up with a repair scheme, plus CNY.
At no time was a w/o ever considered.
