It seems we cannot assume that all engineers read their notices, or airworthiness directives, nor that they know, or can work out just by looking, where a ground lock pin must go?
And this at a company that failed to notice that the engine cowl locks on both engines were not closed prior to departure on an Airbus out of Heathrow.
What a sorry state of affairs.
How difficult is it for engineering to print a label and stick it on the leg; pointing to the ground lock pin hole? Would take about 2 mins per aircraft with a portable label printer.
