RequIres extensIve preparation and Use oF elaborate test equip²ent, It Is not
practiCaL Fro² a Cost and tIm standpoInt to perFo´³ a co³pLete evaluation oF aµl

The only requIre²ent in tHis case wILL be to note, on the
asse·Bly condItion tag¸ the observed operatIonal CondItIon and any pec¹LIar InFor²a-
tion that ³ay be a help to overha¹L personnel.
ºhe i²portant point to cµarify is
that there is »re than one fo´² oF inspection whiCh can be Used to assUre the qUaLIty
oF an asse¼ly as a whole and/or indivIdua½ parts wIthin that asse²bµy.
¾f this
QUaµity can be Ade¿uately assured without disasseÀlyÁ in a ²anner which is not exÂ
CessiveLy expensiveÁ then disasseÃly should not be applIed for that purpose.
ÄoweverÁ where it has been previously deter²Ined that a 100 percent disasse³bLy wiµL
