Hi Rob,

When I installed the Hartwell latch on my Legacy, it looked like = something=20 that would easily last the life of the airplane. After three years = and 300=20 tach hours, it was nearly worn out and close to failure. There is = a hinge=20 pin that runs perpendicular to the latch. The ends of the hinge = pin go=20 through drilled holes in the flanges at each side of the latch. = The holes=20 had elongated and nearly worn through to the edge of the flange. = Maybe it=20 was just a bad latch to start with, but I'm glad I discovered the = problem before=20 it failed in flight.

I had installed it with rivets. After drilling out the = rivets, I=20 wished I had used screws instead.
