LP-314-T2

[petef]

Hi

I'm sitting with a similar problem on an aircraft that has been asked by another engineer a while ago - for background I repeat his question

"I'm trying to track down material property information for LP-314-T2 sheet. It seems to come under a generic LN 9073 standard. I have to carry out a sheet metal repair to an aircraft with this type of skin, but can find any reference to LP-314-T2 anywhere and only basic references to LN9073. I was hoping to replace with 2024-T3 but have no idea what the mechanical properties are."

Can anyone confirm which spec is the closest to LP-314-T2? It appears that LN9073 lists several alternatives (2024-T0/T3/T351, 6061-T0/4/6,7075-T0/6 & 7475-T0/761).

If you cannot find the standard (it may be old, foreign, obsolete...) why not testing a bit of the existing material (if available) for hardness, composition and metallography?
You will then know which alternative may be adequate.
