Boeing Tech Bulletin B737 # 99-6r1
 

Dear Flyers,

I am looking for the cancellation date of Boeing Technical Bulletin 99-6R1 (737), 64R1 (757/767) , 5R1 (777) or 46R1 (747) issued on March 31, 2000.

The Subject is : Inadvertent Entry of Zero Fuel Weight (ZFW) into the Gross Weight (GW) Line of FMC

It was probably canceled somewhere at second half of 2000. If you have an old FCOM (issued in 2000) it will be helpful.

Thank you for your time :ok:

FMC Ops Program Update
 

757/767 software upgrade to Peg 2003 removed the GW entry option amongst other things. FOTB 757-72/767-70 6/2/2004 Pegasus 2003 FMC OP update. Unsure if this cancels the quoted FOTB, it would depend on an airline choosing to update the software.
