AD NUMBER: 2005-08-03
MANUFACTURER: Cessna SUBJECT: Airworthiness Directive 2005-08-03 SUMMARY: The FAA is adopting a new airworthiness
directive (AD) for certain Cessna Model 680 airplanes. This AD
requires revising the airplane flight manual (AFM) to add
procedures to facilitate recovery of the cockpit display units in
the event that the cockpit display units go blank, and to add
flight crew briefings on the use of standby instruments in case the
cockpit display units go blank and do not recover. This AD also
requires repetitive tests of the avionics standard communication
bus (ASCB) for any failures, and corrective action if any failure
is found. This AD also requires installing hardware and avionics
software upgrades; installing the upgrades will allow removal of
AFM revisions and will end the repetitive inspections of the ASCB.
This AD is prompted by are port indicating that analysis of the
Honeywell Primus Epic systems installed on Cessna Model 680
airplanes revealed that all four of the cockpit display units could
go blank simultaneously. We are issuing this AD to prevent a
simultaneous loss of data from all four cockpit display units, and
loss of primary navigation instruments, autopilot, flight director,
master caution/warning lights, aural warnings, global positioning
system position information, and air data and altitude information
to non-avionics systems. These losses could reduce the flight
crew's situational awareness, increase flight crew workload, and
consequently reduce the ability to maintain safe flight of the
airplane.
