U.S. - Mexico Bilateral Aviation Safety Agreement (B.A.S.A.)


In September 18, 2007 during the ICAO Assembly in Montreal, the U.S. Secretary Mary Peters and México Minister Luis Tellez singed the Bilateral Aviation Safety Agreement (BASA) that will facilitate an increase in the ability to exchange aviation products and services between both countries.


Bilateral Aviation Safety Agreement

Bilateral Aviation Safety Agreements provide for bilateral cooperation in a variety of aviation areas, including maintenance, flight operations, and environmental certification. For aircraft certification, an additional document, an Implementation Procedures for Airworthiness, is developed to address specific areas such as design approvals, production activities, export airworthiness approval, post-design approval activities, and technical cooperation.

This Bilateral Aviation Safety Agreement between The U.S. and México includes the approvals to DGAC Mexican civil aeronautical entity -Dirección General de Aeronáutica Civil- to certify manufactured goods in México.


Manufacturing under Technical Standard Order Authorization (TSOA)

I am a Technical Standard Order (TSO) approved manufacturer and plan to shift manufacturing of my articles to México. What are the necessary steps to retain my FAA TSO Authorization?

An FAA TSO Authorization represents both a design and production approval. While it may be possible to shift some manufacturing of a TSO article to a foreign country, please note that FAA TSO Authorization cannot be transferred under any circumstances [14CFR § 21.621(c)]. Once the entire manufacturing of a TSO article is occurring outside the U.S., the revelant FAA approval becomes a Letter of TSO Design Approval under a bilateral agreement [14 CFR Part 21.617].

Contact the FAA ACO/MIDO office that is responsible for certificate management of your TSO Authorization. Generally, if the TSOA involves manufacturing activities at a location outside of the U.S., the FAA must determine whether the proposed activity poses an undue burden on the FAA. The FAA drafts the Undue Burden Paper using information provided by the applicant [14 CFR §21.604(c)].
