Completely valid point.
I'd be willing to wager the end result of this will be that testing will show minimal impact on fatigue life and Van's will offer some support as they have already indicated. So it will be left to the builder to decide whether to accept that coupon testing correlates to full scale components, the DAR's will sign off on planes with LCP and/or that resale value won't be adversely affected.
I’m sure your statement will be correct sir.
What I’ve seen in my parts that crack when I dimpled and if the industry is going to buy off on installing cracked parts. Makes me wonder why I spend so much time deburring holes when I can just match drill, dimple, rivet and go on. I know, I know. The engineers and science will say those specific parts will last just like Boeing engineers say the original 737 has the same type cert as a 737 max10. I digress.
From an A&P perspective, I’ve fixed corrosion, cracks, etc, but I’ve never installed a part with a known defect that an engineer has said it’s ok. I’m sure it’s possible but I or the owner would require the test documents be included with the part and would become permanently part of the logbook. Just as AD’s, SB’s etc that address known or suspected issues remain part of the logs.
