No Thor, I don't project anything. I look at all of the data with the same objectivity, and I never bank anything on a single piece of data. It's just like investigating anything else, you find all of the resources you can, cross reference known data, find other data that may not be directly linked but is nontheless pertinent to the path towards a conclusion, find supporting data, study the science behind the data, then put it all together and attempt to validate it using every aspect.

That one piece of paper is not absolute irrefutable evidence. The translation may say approved limits, but without any other pages from the test report, there is a significant lack of context under which that statement was made. Was it an experimental flap design? Was it an experimental wing design? Was it a controlled stress test of the flap and wing together or just the flap? Was it a live test to the point of failure on every increment (which means someone risked life and limb for each increment)? What exactly failed at each level? Those questions and others must be asked and answered before the data can be valid.


109/110 flap test sheet

I got that piece of paper from the same source that coughed up the one you have and he believed there were 9 sheets but didn't have them all.

You think extensive tests are done overnight? If Bulldozer didn't get you that page, then I assumed in error. Check your pm's.

no i found the sheet in another discussion on the same topic on another board, i requested a copy from the poster. 

it sounds like these were 2 pages of 9 he received in reply to a request he made on the subject.

sounds like the pages themselves may not be related other than that they refer to the same topic.

i.e. not part of the same report.

That may very well be possible.

Having to rely on outside resources makes the data difficult to track properly. Complete works are extremely rare.

OMG...If I was a pilot I'd give my left testicle to put that plane through the paces, but I thought the Brits put it in a museum. No film crew needed, just a few mini-dv cameras mounted in the cockpit, 3 would get all the angles needed.

it just knaws at me that any aircraft designer would design any control surface (primary or secondary) that is weaker than it stated structural limits at any point in during its normal function.

i think there must be some other reason out there for the low speeds in the POH ...
