VH-TJO Fuselage dents?
Spotted this the other morning and took a few pics.
http://www.jetphotos.net/palbum/viewphoto.php?id=6670 What would cause that sort of pattern denting on the lower fuselage? And I have circled what appears to be a small hole, however I am sure its probably not. I don't know much about aircraft but I am sure some on here would be able to shed some light? Nick |

April 10, 2005, shows a simimlar pattern on the fusealge. And something similar seems to exist in this photo in the same area, taken August 3 2004. http://www.jetphotos.net/viewphoto.p...443652&nseq=22 |
Anybody know what caused/causes this to happen?
|
I can speculate..
Speed holes..they make the plane go faster:p |
It looks like its been hit multiple times with a rolling pin :o

Something tells me you can't help but break out in tune every time you see a monorail, Nick. :p

love to know the actual reason for it though! |
The ripples in the fuselage are caused by shear loads between the tail and C of G or undercarriage due to turbulence or heavy landings. The skin stretches are the moment of tension and deforms leaving a permanent wrinkle.
Each skin dent/buckle is recorded (most of which you'd never be able to find!) and must remain within certain limits. The wrinkles disappear in-flight when the a/c is pressurised. It is obviously more common on the longer length 737 models. |
Liam, thanks for the explanation. All makes sense now! I am sure seeing TJO is one of the older 734's that she has seen many turbulent and rough landings!
