B. Reason 
As part of the modification performed during the B767-300BDSF conversion part 
of the pitot-static tubing is reinstalled after installation of the structural 
reinforcements and new installations. Two erroneous conditions (potentially 
creating water traps) were found in the tubing located below the 9G rigid barrier 
reinforcements and connecting the pitot and the static system tubing to the right 
ADC (Air Data Computer) belonging to the first officer system. 
 
In case of water accumulation in this tubing, the right ADC may report erroneous 
airspeed and altitude reported on EICAS caution messages “IAS DISAGREE” or 
“ALT DISAGREE”. The related Flight Crew Operating Manual (FCOM) 
procedures ensure safe operation in case these reports occur during flight.  
 
Note: At the time of writing this Service Bulletin, no malfunction has been 
reported by any B767-300BDSF operator. 
 
C. Description 
This Service Bulletin provides instructions to perform a visual inspection of the pitot 
and static system tubing of the first officer pitot-static system installed in the main 
and mid equipment center to identify the potential erroneous installation. 
In case a potential erroneous installation is discovered, perform the instructions 
included in this Service Bulletin to correct the installation of the abovementioned 
tubing.
