15. On the basis of the less than optimal overnight rest time
available, the early reporting time for duty, the length of the duty
day, the number of flight legs, the demanding conditions (non-precision
instrument approaches flown manually in conditions of low ceilings and
reduced visibilities) encountered during the long duty day (and the two
previous days), it is likely that fatigue contributed to the pilots'
degraded performance and decisionmaking.



16. Existing Federal Aviation Administration pilot duty regulations do
not reflect recent research on pilot fatigue and sleep issues,
increasing the possibility that pilots will fly in a fatigued
condition.
