takata: thanks for the excerpt from the NW analysis of the malfunction.
This observation of yours is one that the industry may or may not be able to remedy. (Aren't there tools/forums/industry standing working groups that concern themselves with such issues across all corporate boundaries? )
Only companies operating both Boeing and Airbus on the same lines (and for a long time) could really make an informed comparison about those failure rates related to manufacturers/models. Sadly, they really don't like to publish those informations about their fleet "failure rates": classified matter.
Is there not a means to issue "cleansed" or "raw" analysis discovered? Would not the Aircraft manufacturers and any company who operates their aircraft be in dialogue over such malfunctions?
Don't understand the industry well enough to understand if I am even asking the right question.
