Monday Accident & Lessons Learned – Sometimes a Repeat Failure IS NOT a Repeat Failure…
Last Monday I published an article titled:
The Danish Accident Investigation Board has published a report that suggests that this third Dash-8 Q400 accident was NOT a Repeat Failure but rather a failure of the landing gear from a totally separate cause.
To see the Danish Accident Investigation Report go to:
The investigation shows that this accident could have been caused by an o-ring failure and prior landing gear replacements (although the investigation is not complete).
Lesson Learned: You can’t assume that a failure is a Repeat Failure until the investigation is complete and you are sure that the cause is indeed the same.
One more note: The o-ring failure might be a Repeat Failure. The difference is that this time they moved a component from one system to another that allowed the failed o-ring to enter the landing gear system. (See the report for more info.)
