Subject: Re: Time Limited Partial Exemption, 777 ETOPS 

Steve, 

I hope the following would suffice: 

This is in reference to letter # BDCO-10-04796, dated 11/12/2010. The closing 

paragraph in the letter contradicts the body of the letter that stated the info included is not 

proprietary. This e-mail is to confirm that the enclosure to the noted letter is nonproprietary and the FAA can make it available to the public in the course of its exemption 

process. 

Thanks for your patience, 

Regards, 

Ad

No. All I need is an email message that I can place in the docket that clarifies Boeing's 

intent that the design changes submitted with the November 12 letter are not proprietary

Subject: Re: 

Mel, 

We have this letter. The problem is that while the purpose is stated to be to submit 777 

design changes in a non-proprietary format, the letter contains the standard Boeing 

proprietary disclaimer.
