In our ppinica, tnic obscrictiin' requires resolution by II:II g

and the licensea.

It has i. con suggested that the reflectors ray be s,n11 enou;h to be ceco : table to the Code Eules under a

y which the ex M r.ation was ccaducted.

2 Even though the fleus =.cy be of an acceptable sice, we believe 4

the ui.:ustion varrants furtrier investigation, since the coda 5

dafinition of " acceptable" flew cice is intended to cceept only those flawa whien vculd not reasonably be expected to gree durin.

1 t.;e service life of the co=ponent.

If reficctors of "acceptahic" g

s u.e arc, in fact, growing as a result of one pressure cycle, it

~'

udC appear necescry to reecasider their acceptability.
