Candy, If you read my post, you'll notice that I mentioned making certain the bold would be the correct spec. I don't advocate using substandard materials. But, when I hear AI's grounding planes because the fuel valve, or example, is not the original, I get upset. They can make you go through hell if they want to, even though the replacement part is fully certified for Aeronautical use, but is just not the original. You tell me, what purpose do they serve when they do this. I fully believe that when making any structural, or "major" modifications, they need to be fully approved. But, when something totally insignificant, such as a fuel valve, or in my case, the spring in the brake master cylinder, is not exactly the same as original equipment, it is counter productive to ground the plane when the non original replacement part is arguably superior to the original part that was produced over 50 years ago. Keep in mind that after they've made you jump through all the hoops, they normally approve the installation anyway.
