REQUEST FOR EXTENSION OF TIME TO FILE COMMENTS OF A IRPORTS

COUNCIL INTERNATIONAL

– NORTH AMERICA

Airports Council International

- North America (“ACI

- NA”) appreciates this opportunity

to submit comments on behalf of its member airports in response to the Federal Aviation

Administration’s (“ FAA’ s ”) n otice of proposed rulemaking that proposes to update, simplify

and streamline rules of practice and procedure for filing and adjudicating complaints against

federally

- assisted airports. (77 Fed.Reg. 13027, March 5, 2012) (“NPRM ”)

. The proposed

changes offer s ignificant improvements in the efficiency of the FAA’s rules of practice for

federally

- assisted airport enforcement proceedings and we applaud the agency’s efforts.

ACI

- NA represents the local, regional and state governing bodies that own and operate

the p rincipal airports served by scheduled air carriers throughout North America. ACI

- NA

member airports are responsible for approximately 95 percent of the domestic and virtually all

of the international airline passenger and cargo traffic in North America

. ACI

- NA has been

working with it s member airports in the review and coordination of comments in this

proceeding. Unfortunately, we have not been able to complete our review and coordinate

comments received from members impacted by the proposed changes by t he FAA’s requested3

comment deadline of May 4, 2012. Because of the importance of the proposed enhancements

in the rules of practice to our members, we respectfully request a three week extension of time

(until May 25 , 2012) to submit our comments. We be lieve that the additional time would make

for a greater ability to coordinate comments with representative airports, and contribute to

meaningful input in the FAA’s review of the proposed modifications in its Rules of Practice.

We appreciate your consider ation of this request.

Re spectfully submitted,
