Hi all,

A friend of mine took this photo Friday, He is(I am as well) curious as to what these marks on the rear fuselage may be.
The grey lines..

Cheers

Chris

If your camera sends text messages, that could explain why your photos are rubbish!

This reminds me of the marks on some ancient FR 732s:

The upper mark on the QF bird appears like it might be running along the top of the window belt, as the FR marks do.

Incidentally, the second FR picture caption reads "This is one of four grounded Ryanair 737-200's at Prestwick due to scratching of the fuselage that was discovered during maintenance checks". You'd have to hope that the scratching that caused the grounding wasn't the incredibly obvious lines that would hardly need "maintenance checks" to notice, wouldn't you? Smile

Or was it just a question of the severity of the damage?

Do you have to remove some of the paint in order to check the joins properly?

Ultrasonic testers work fine.
I Feel the lines are the ends of a Structural repair carried out.Anyone with Different angle views. Or Worn Paint.

It is an area over the lap joints that has been paintstripped for inspection purposes. Our aircraft have had the same thing done recently to inspect for corrosion over a similar area, though at the front of the aircraft.

Presumably in the case of my grounded 732s then, the sequence went: paint stripped, damage found, aircraft in doghouse.

I'd wondered where these mythical lap joints were...

I doubt that they are bare. It looks like some sort of lap seam inspection for S-10L & S-20L. Curious why they left out S-14L. Standard parctice is to re-seal the lap seam if the sealant was removed, and at the very least, prime it with BMS-10-11 primer (which is green).

So am i as I've always been told that the paint helps in the strengthening of the aircraft because the metal is so thin.

Er, try strengthening something with paint. And then look at an AA aircraft.

I must admit it is strange, as our aircraft had 3M adhesive film applied over the bare patches until their next inspection, to protect the bare metal surface.

While I can't speak for QF, the inspection on our aircraft was due to knife marks, and corrosion from previous decal applications. The operator had obvious;y used a stanley knife to trim them, and damged the skin at the same time.

To me it looks as if the joints have been sealed but not yet painted over.

Is what advisable? Sealing and not painting? IMO, sealing is the bare minimum. Some primer would be nice.

ps, try using question marks (?).
