Default VH-TJO Fuselage dents?

Spotted this the other morning and took a few pics.

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

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

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!
