OMB 8/9 CDL/MEL

Question 0

You have four CDL items. In the remarks and or exceptions column of the CDL there are no performance penalties indicated for removed items (negligible items). Does this mean you do not have to consider any performance penalties at all?

Answer 0

No. CDL states that no more than 3 items of such items can be missing without making a correction. When more then 3 are missing you have to decrease limiting weights by 50KG for each additional item.
