I know that it's never say never when it comes to this sort of thing but I'm thinking that the pickle-fork issue is probably not related to the winglets.While memory is conceptualized predominantly as an individual capacity in the cognitive and biological sciences, the social sciences have most commonly construed memory as a collective phenomenon. On the flip-side it looks like all Korean Air B737s that are fitted with winglets are still flying. I've been trying to get a line on the LSNs of the grounded aircraft and noticed something with regards to the Korean Air aircraft that have stopped flying recently - none of them were fitted with winglets. Perhaps more engineering learned members than I might like to comment?

Possibly those B737s that were designed from the outset to have Split Scimitar winglets might have strengthened pickleforks to account for the increase in bending loads.īut those B737s (eg, 800, NG) that were fitted with the after-market mod Scimitar installation (without beefing up the wing attach load path design) would necessarily suffer a reduced wing attachment fatigue life due to the higher loads imposed by the addition of the Split Scimitar winglets.
There is also the possibility/probability that the addition of the Split Scimitar winglets has had an adverse effect on the wing bending loads carried by the pickle forks.Īpparently the spanwise lift distribution has shifted the centre of lift further outboard on the wings which would necessarily give rise to greater wing bending loads at the wing attachment points from both static flight and gust loads. The events of the past few months got me thinking that maybe Qantas is not led by as smart people as they thought they were. If something happens to any of Qantas's 737s (and I sure hope it doesn't), this is not just a PR disaster, this is a guaranteed social death. But not for any money in the world would I post a response like that just a few months after two deadly disasters that were caused by managers not listening to engineers. I'm an adventurous person and I like risky bets. Whoever doesn't like unions, he should've chosen his words A LOT more carefully. The tone of this statement itself is simply outrageous. So Qantas trusts the "regulators" and "manufacturer" who both have JUST been caught cooking the books and making Powerpoint presentations to rectify the death of 346 people, but dismisses their own country's engineers who actually know what they are saying, as "irresponsible". Quntas's response (quote): The Oneworld carrier says it "rejects the alarmist claims" for grounding made by the engineers' association which, it argues, are "irresponsible and completely inconsistent with advice from regulators and the manufacturer". Steve Purvinas, Federal Secretary of the Australian Licensed Aircraft Engineers AssociationOh, it gets better. "Boeing had previous thought the cracks were only occurring on aircraft with over 35,000 landings, the issue has now been identified on two Qantas aircraft with as few as 27,000 landings and Qantas are yet to inspect the majority of its 737 fleet."
