Hi H Peacock --
If the static piping in the wing was leaking as you suggest then you'd get huge changes in 'static' pressure as the wing was loaded and then unloaded. Any pitch change would cause a very noticeable movement of the altimeter and a smaller jump on the ASI.
Yup. I think you're right. It would be more related to AOA than pitch per se but the elasticity of the wing section as load varies
might have opened a leak. The report specifically states that the static couldn't be verified due crash damage. The report also states that the altimeter indication could not be verified.
From my own flying I cannot disagree that the height discrepancy might have been obvious without reading an altimeter. But an opinion on that is totally outside my competence.
Anyway, may I wish you an enjoyable weekend and thank you for engaging in discussion
