Narrative:

There is a discrepancy on cdl (confign deviation list) embraer book. It states that no more than 1 part of any 1 system maybe missing, unless specific combinations of parts are included in the cdl. On aircraft tail XXX, there are 2 cdl's: 32c02, main landing gear wheel fairings and 32c01, main landing gear doors. These 2 parts are under 1 system, which is system 32. According to our maintenance control, those 2 cdl's are legal and there is no restr with what the statement on the book says. However, several dispatchers disagree with it. My analysis is, there are 4 parts on this system. As on the computer, there are only 3 parts that had been cdl by the maintenance (32c02 and 32c01). Thus, it satisfies the requirement of...' unless specific combinations of parts are included in the cdl.' nonetheless, the statement is somewhat unclr, leading to different interps between dispatchers and maintenance. Those 2 cdl's have a same restr on aircraft XXX, which is airspeed restr to 250 KIAS, mach .65. To solve this issue, embraer should make clear on how to write their restr language on the MEL/cdl book. Perhaps they should have amendment of language attached to the original book. Furthermore, the moc/maintenance should have the amendment. As of flight crew members, we, the flight dispatchers, can only rely on our moc expertise and professionalism on how to handle missing parts on the embraer and to interpretation the restr.

Title: AN EMBRAER 140 DISPATCHER RPTS CONFUSION AND DISAGREEMENT ON THE INTERP OF THE EMBRAER CONFIGN DEV LIST.

Narrative: THERE IS A DISCREPANCY ON CDL (CONFIGN DEV LIST) EMBRAER BOOK. IT STATES THAT NO MORE THAN 1 PART OF ANY 1 SYS MAYBE MISSING, UNLESS SPECIFIC COMBINATIONS OF PARTS ARE INCLUDED IN THE CDL. ON ACFT TAIL XXX, THERE ARE 2 CDL'S: 32C02, MAIN LNDG GEAR WHEEL FAIRINGS AND 32C01, MAIN LNDG GEAR DOORS. THESE 2 PARTS ARE UNDER 1 SYS, WHICH IS SYS 32. ACCORDING TO OUR MAINT CTL, THOSE 2 CDL'S ARE LEGAL AND THERE IS NO RESTR WITH WHAT THE STATEMENT ON THE BOOK SAYS. HOWEVER, SEVERAL DISPATCHERS DISAGREE WITH IT. MY ANALYSIS IS, THERE ARE 4 PARTS ON THIS SYS. AS ON THE COMPUTER, THERE ARE ONLY 3 PARTS THAT HAD BEEN CDL BY THE MAINT (32C02 AND 32C01). THUS, IT SATISFIES THE REQUIREMENT OF...' UNLESS SPECIFIC COMBINATIONS OF PARTS ARE INCLUDED IN THE CDL.' NONETHELESS, THE STATEMENT IS SOMEWHAT UNCLR, LEADING TO DIFFERENT INTERPS BTWN DISPATCHERS AND MAINT. THOSE 2 CDL'S HAVE A SAME RESTR ON ACFT XXX, WHICH IS AIRSPD RESTR TO 250 KIAS, MACH .65. TO SOLVE THIS ISSUE, EMBRAER SHOULD MAKE CLR ON HOW TO WRITE THEIR RESTR LANGUAGE ON THE MEL/CDL BOOK. PERHAPS THEY SHOULD HAVE AMENDMENT OF LANGUAGE ATTACHED TO THE ORIGINAL BOOK. FURTHERMORE, THE MOC/MAINT SHOULD HAVE THE AMENDMENT. AS OF FLT CREW MEMBERS, WE, THE FLT DISPATCHERS, CAN ONLY RELY ON OUR MOC EXPERTISE AND PROFESSIONALISM ON HOW TO HANDLE MISSING PARTS ON THE EMBRAER AND TO INTERP THE RESTR.
