I think you will find that at Shell Aircraft's direction Sikorsky have made a solution to this (minor) cracking problem their top priority
in the same way that the gearbox churning problem was prioritised at Shell's insistance over other failure modes.
Squibb 66 There is no need to ask sikorsky
"extremely remote" is defined in FAR29.1309
and as the S-92 is certified to the latest certification standards in accordance with Shell's 7/7=1 safety strategy
, it (and its MGRB) meet that
.
