Federal Aviation Administration, DOT.
Final rule; request for comments.
This amendment adopts a new airworthiness directive (AD) for the Eurocopter Model EC225LP helicopters. This AD requires inspecting the side mount of the pilot and copilot seats to determine if any floor attachment screw, nut, or washer is missing. If a screw, nut, or washer is missing, this AD also requires installing airworthy parts. This AD is prompted by a report that some of the floor attachment screws and nuts under the pilot and co-pilot seats were missing. Further investigation has shown that some of the cup washers that need to be used in installing countersunk head screws that attach the pilot and co-pilot seat frame to the floor were missing. A missing floor attachment screw, washer, or nut, if not detected, could reduce the strength of the seat attachment. The actions specified in this AD are intended to detect a missing floor attachment screw, washer, or nut and help prevent detachment of the seat from the floor during an emergency landing.
Effective November 14, 2011.
The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of November 14, 2011.
Comments for inclusion in the Rules Docket must be received on or before December 27, 2011.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2010-Start Printed Page 666140030, dated February 26, 2010, to correct an unsafe condition for the Eurocopter Model EC225LP helicopters. EASA reports that on several newly-produced helicopters, some screws and nuts that attach the frames of the pilot's and co-pilot's seats to the floor were missing. Further investigation has shown that some of the cup washers that need to be used in installing the countersunk head screws, which attach the pilot's and co-pilot's seat frames to the floor, were missing. EASA states that this condition, if not corrected, reduces the seat attachments strength, and it could result in no longer retaining the seats in place in the event of an emergency or hard landing.
Differences Between This AD and the EASA AD
We refer to flight hours as hours time-in-service.
Related Service Information
Eurocopter has issued Alert Service Bulletin No. 53A020, Revision 0, dated February 17, 2010 (ASB), which specifies checking for the presence of screws and nuts on each side of the pilot's and co-pilot's seat mount. If one screw or one nut is missing, the ASB specifies removing the affected seat, checking for cup washers, and performing the specified corrective action to return the seat to conformity.
FAA's Evaluation and Unsafe Condition Determination
This helicopter has been approved by the aviation authority of France and is approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, their technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of this same type designs.
There are no helicopters of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these helicopters are placed on the U.S. Registry in the future.
Costs of Compliance
There are no costs of compliance since there are no helicopters of this type design on the U.S. Registry.
FAA's Determination of the Effective Date
Since there are currently no affected U.S. registered helicopters, we have determined that notice and opportunity for prior public comment before issuing this AD are unnecessary and that good cause exists for making this amendment effective in less than 30 days.
Requirements of This AD
This unsafe condition is likely to exist or develop on other helicopters of the same type design that may become registered in the United States. Therefore, this AD is being issued to require, within 85 hours time-in-service (TIS), unless accomplished previously, inspecting for the presence of 4 screws and 4 nuts on each side of the copilot's seat mount and 1 screw and 1 nut on each side of the pilot's seat mount. If any screw, nut, or cup washer is missing, this AD requires removing the seat and mount and, before further flight, counter sinking the hole and installing airworthy parts and replacing the mount and seat. The actions must be done by following specified portions of the ASB described previously.
This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES. Include “Docket No. FAA-2011-1074; Directorate Identifier 2010 SW 028 AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact with FAA personnel concerning this AD. Using the search function of the docket web site, you can find and read the comments to any of our dockets, including the name of the individual who sent the comment. You may review the DOT's complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477 78).
We have determined that notice and prior public comment are unnecessary in promulgating this regulation; therefore, it can be issued immediately to correct an unsafe condition in aircraft since none of these model helicopters are registered in the United States. We have also determined that this regulation is not a “significant regulatory action” under Executive Order 12866. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the AD docket.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.Start List of Subjects
