If the AMM allows for fitment of a single washer, why is the fact that the bolts were installed accordingly a problem? It appears that two of the three engines "wrongly" installed were actually installed in accordance with the maintenance manual. The third appears to be a f$&k up.
Just curious as to why this is an issue for those two engines that appear to have been installed in accordance with the maintenance manual so a serious question, not s$&tstirring. Thanks.
