During the last month I've been working in Argentina for my company. I've flown on LH 747-400 (D-ABVS) from GRU to EZE on Feb 25th and on D-ABVT from EZE to GRU on March 22nd.
Since I was at the Business class I was near the nose gear and I could hear, when the captain steared it, a creaking noise comming from it. I could hear it on both planes that I've flown, so I think that it was not a isolated problem in one aircraft only.
BTW I recorded the backtrack procedure at RWY 35 at EZE and you can hear that creaking sound in it.
and here you can see the takeoff: http://www.youtube.com/watch?v=NKnB-gBgrW0
So, what is this creaking sound and why is it produced???
Thanks and best regards!
