9. Troubleshooting
This section describes conditions associated with suspected
malfunctions in the flight control system. Proper awareness helps the
pilot make write--ups that convey the necessary information to
maintenance personnel. As aresult, unnecessary and expensiveflight
time to verify pilot squawks can be greatly reduced.
This section doesnot imply that the pilot must troubleshoot the system
down to the box level. Rather, the paragraphs that follow contain
information required to give the pilot a complete understanding of
system problems.

THE FLIGHT CONTROL SYSTEM HAS BEEN DESIGNED TO EX-
HIBIT A HIGH DEGREE OF FUNCTIONAL INTEGRITY.HOWEVER,
THE USER MUST RECOGNIZE THAT IT IS NOT PRACTICAL TO
MONITOR AND/OR SELF--TEST FOR ALL CONCEIVABLE SYS-
TEM FAILURES. IT IS POSSIBLE THAT THE SYSTEM CAN OPER-
ATE ERRONEOUSLY WITHOUT A FAULT INDICATION. IT IS THE
RESPONSIBILITY OF THE PILOT TO DETECT SUCH AN OCCUR-
RENCEUSINGCROSS--CHECKSWITH REDUNDANTORCORRE-
LATED INFORMATION AVAILABLE IN THE COCKPIT.

completely logged in. Effective communication significantly
improves the troubleshooting process.
