This crash resulted in an AD: mine 'failed' and it cost me c.£20k (long story) to put right.
But there was no paint on my t/r gearbox support. Maybe the AAIB should have taken a look at my support too.
IIRC the AAIB report blamed the elongated holes for the accident, without specifically drawing the conclusion that it was the paint causing the original fretting that allowed the bolts to 'work'.
