FAA Clarifies Use of MMI

On Oct. 15, ARSA received a response from the FAA to the Association’s request for clarification regarding the use of maintenance instructions modified according to EASA part 145.A.45(d). In its letter, the agency concurred with ARSA’s interpretation and agreed that such modified maintenance instructions are fully acceptable to the FAA under the Agreement between the United States of America and the European Community on Cooperation in the Regulation of Civil Aviation Safety.

Specifically, the agency stated that, “The FAA considers the EASA approved MMI’s to satisfy and be equivalent to the requirements of 14 CFR part 43.13(a). The EASA approved MMI’s can also be used by an EU based repair station just as the requirements of 14 CFR part 43.13(a) apply to US-based repair stations.”
