(Page 34) Here, the NTSB describes its review of the transcripts of other
accidents and states that it “did not observe instances on these CVR recordings in which a pilot
failed to exhibit surprise, alarm, or increased stress . . . .” The NTSB’s purpose in making this
comparison with Flight 990 obviously is to suggest that the absence of exclamations from the
RFO indicates he was in control of the events and, therefore, was not surprised. First, the NTSB
fails to note that the instances it uses for comparison all involved circumstances where there
were two or more crewmembers in the cockpit at the beginning of the accident sequence.
Consequently, many of the comments appear to have been made as part of the communication
from one crewmember to another. Although there is no evidence to prove that the RFO was
alone in the cockpit, the NTSB assumes this to be a fact. Therefore, the circumstances of Flight
990 are unlike any of those studied by the NTSB. Second, and more important, the NTSB
provides no data or studies to show that the absence of an excited utterance is in any way
meaningful, much less that it is indicative of an intent to crash an airplane. Consequently, there
is no evidence in the record to support a view that the RFO was acting improperly.
In contrast to the lack of evidence concerning the meaning of the absence of an excited
utterance, there is specific, expert evidence in the record that the NTSB ignores completely. An
Egyptian psychiatrist, Dr. Adel Fouad, listened to the entire CVR tape and provided a detailed
report substantiating his conclusion that the RFO was acting normally and interacted
appropriately with the Captain. The NTSB surpressed this evidence in its report and provided no
explanation as to why Dr. Fouad’s opinion -- the only expert medical opinion obtained during the
investigation -- was completely ignored.

(Page 37) The report should be clarified to reflect that it could not be determined
if portions of either the right or left elevator surfaces were recovered or were present at either
wreckage site.

(Page 39) Although the NTSB notes the unusual characteristics of the internal
mechanisms of one of the right-side PCA’s, nowhere does the NTSB discuss the fact that in the
entire course of the five-year USAir Flight 427 investigation, it did not find any anomalies on the
