Schrieber, Aerospace Engineer, Los Angeles Aircraft Certification Office, Transport Airplane Directorate, FAA, 3960 Paramount Blvd., Lakewood, CA 90712; telephone (562) 627-5348; email eric.schrieber@faa.gov (regarding Model R22 helicopters); or Fred Guerin, Aerospace Engineer, Los Angeles Aircraft Certification Office, Transport Airplane Directorate, FAA, 3960 Paramount Blvd., Lakewood, CA 90712; telephone (562) 627-5232; email fred.guerin@faa.gov (regarding Model R44 helicopters).

Airworthiness Directive 2011-12-10, Amendment 39-16717 (76 FR 35330, June 17, 2011), currently includes the following paragraph (b) in the compliance section:

“(b) If you find any bare metal in the area of the skin-to-spar bond line, before further flight, inspect the blade by following the requirements of paragraph (d) of this AD.”

As published, the reference to paragraph (d) is incorrect. The correct reference is to paragraph (c). Paragraph (c) contains the inspection requirements, and the incorrect reference to paragraph (d) is confusing. We have also added the word “inspection” to clarify that the requirements we are referring to are the inspection requirements, not the compliance times.

No other part of the preamble or regulatory information has been changed; therefore, only the changed portion of the final rule is being published in the Federal Register.
