The American Airlines electronic submission was on letterhead that did not include the carrier’s mailing address at 1 Skyview Dr, Fort Worth, Texas. It also did not list.. a fax number.
As the government explains, 14 CFR § 11.81 requires listing “[y]our name and mailing address, and, if you wish, other contact information such as a fax number, telephone number, or email address.” Since the FAA doesn’t know where to find American Airlines, and didn’t think to ask the agency’s own American Airlines Certificate Management Office, they declined to consider the request to place doors on business class seats.
