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 co ntradicts the body of the letter that stated the info included is not proprietary. This e-mail is to confirm th at 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

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.
