I've just come across an article in the July 2018 edition of the the Professional Body's magazine of my "chosen" profession.
I quote:
" Defence News reported earlier this year (2018) that the US Army had stopped taking deliveries of the AH-64E Apache attach helicopters from Boeing in February. The US Army explained that 'the service is not confident in the durability of what it deems a "critical safety item" - a strap pack nut that holds very large bolts, that subsequently hold the rotor blades on the helicopter'
(snip)
'Clearly these items are safety critical components and for Boeing (the manufacturers) not to have extended its investigation of the testing of other safety critical components, particularly the whole rotor assembly is concerning' "
So is Boeing really placing safety at the top of its agenda on both (or either) military and commercial products?
