Thank you for the opportunity tocomment on this rulemaking exercise. We have the following comment.
The second sentence in the Unsafe Condition Statement, paragraph d, currently reads:
"This defect would cause the upper panel of the fan blade to be liberated following foreign object damage (FOD) or a bird strike and likely result in an inflight shutdown (IFSD).
The outcome of an FOD or bird strike event will not necessarily result in an outer panel release, therefore it is suggested that the sentence be replaced with the following to more accurately relect the possible outcome:
"This non-conforming condition could increase the potential for damage during a foreign object impact. This secondary damage could include liberation of the upper panel of the blade, which increases the potential for in-flight shutdown."
