"For many years I didn't have these long balldrivers. I remember how many times I wish I did. I recall losing an airplane because I was too lazy to take the cowl off to check the tightness of the engine mounting bolts. I remember taking the spinner off and seeing that I could actually get to the engine mounting bolts at about a 10 degree angle but they were about seven or eight inches in, and there was no way any balldriver that I had would reach that far. Well long story short, the engine mounting bolts were loose and I lost the plane!" Rich, RTL Fasteners.
