Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for Eurocopter Deutschland GmbH (Eurocopter) Model BO-105A, BO-105C, BO-

105S, BO-105LS A-1, BO-105LS A-3, EC135 P1, EC135 P2, EC135 P2+, EC135 T1, EC135 T2, EC135 T2+, MBB-BK 117 A-1, MBB-BK 117 A-3, MBB-BK 117 A-

4, MBB-BK 117 B-1, MBB-BK 117 B-2, MBB-BK 117 C-1, and MBB-BK 117 C-2 helicopters with certain part-numbered cantilever assemblies, cyclic stick locking devices, or cyclic stick holder assemblies installed. This proposed AD would require modifying and identifying the cyclic stick cantilever or lock. This proposed AD is prompted by pilots inadvertently taking off with the cyclic locked. The proposed actions are intended to prevent a pilot taking off with the cyclic in the locked position, which could result in loss of control of the helicopter.

DATES: We must receive comments on this proposed AD by March 11, 2013.

ADDRESSES: You may send comments by any of the following methods:

Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your comments electronically.

SUPPLEMENTARY INFORMATION:

Comments Invited

We invite you to participate in this rulemaking by submitting written comments, data, or views. We also invite comments relating to the economic, environmental, energy, or federalism impacts that might result from adopting the proposals in this document. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit only one time.

We will file in the docket all comments that we receive, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued AD No. 2008-0113, dated June 10, 2008, for the Model EC135, EC635 and MBB-BK 117 C-2 helicopters. EASA advises of several cases where takeoff was executed with a locked cyclic stick on EC135 series helicopters, which may lead to loss of control of the helicopter. EASA also advises that the stick-locking device installed on Model BO 105 and MBB-BK 117C-2 helicopters has a similar function as the device installed on the EC135 series helicopters. Therefore, EASA issued AD No. 2009-0079, dated April 1, 2009, to require modification of the cyclic-stick locking/

centering device for the Model BO 105 and MBB-BK 117 helicopters.

After EASA AD No. 2009-0079 was issued, type design ownership for the Model BO-105 LS A3 was transferred from Canada to Germany. Because Transport Canada had not issued an AD prior to the transfer, EASA superseded AD No. 2009-0079 with AD No. 2010-0049, dated March 19, 2010, to include Model BO-105 LS A3 in its applicability. The EASA ADs also require amending the applicable Rotorcraft Flight Manual (RFM).

FAA's Determination

These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design.

Related Service Information

Eurocopter has issued the following alert service bulletins (ASB) for each of its model helicopters:

ASB BO105-40-106, dated December 19, 2008, for all Model BO105 helicopters, except Model BO105 CB-3.

ASB-BO 105 LS 40-10, dated May 8, 2009, for all Model BO 105 LS A-3 helicopters.

ASB EC135-67A-015, dated April 14, 2008, for certain serial-numbered Model EC135 and EC635 helicopters.

ASB-MBB-BK117-40-113, dated December 22, 2008, for all Model MBB-BK117 Models A-1, A-3, A-4, B-1, B-2, C-1.

ASB MBB BK117 C-2-67A-008, dated April 14, 2008, for certain serial-numbered Model MBB BK117 C-2 helicopters.

These ASBs specify procedures to modify the cantilever assembly or the cyclic stick locking device, which allows neutral positioning and centering of the cyclic stick without the locking feature.

Proposed AD Requirements

This proposed AD would require compliance with the manufacturer's service bulletins for each applicable helicopter with a certain part-

numbered cantilever assembly or a cyclic stick locking device installed as follows:

ASB BO105-40-106, dated December 19, 2008, for Model BO-

105A, BO-10C, BO-105S, and BO-105LS A-1 helicopters.

ASB-BO 105 LS 40-10, dated May 8, 2009, for Model BO 105 LS A-3 ASB EC135-67A-015, dated April 14, 2008, for Model EC135 P1, P2, P2+, T2, and T2+, serial number (S/N) 0005 up to and including S/N 0699, excluding S/Ns 0076, 0093, 0098, 0099, 0102, 0104, 0106, 0108, 0110, 0111, 0113, 0114, 0116, 0117, and 0119.

ASB-MBB-BK117-40-113, dated December 22, 2008, for Model MBB-BK117 A-1, A-3, A-4, B-1, B-2, and C-1 helicopters.

ASB MBB BK117 C-2-67A-008, dated April 14, 2008, for all Model MBB BK117 C-2, S/N 9004 through S/N 9230 helicopters.

Differences Between This Proposed AD and the EASA AD

This proposed AD does not apply to Model BO-105D, BO-105DB, BO-

105DB-4, BO-105DBS-4, BO-105DBS-5, BO-105DS, or the military Model EC635 helicopters because these models are not type certificated in the United States. The EASA AD requires amending the RFM, and the proposed AD does not because the RFM revisions have been incorporated by the type certificate holder.

Costs of Compliance

We estimate that this proposed AD would affect 416 helicopters of U.S. Registry.

We estimate that operators may incur the following costs in order to comply with this proposed AD. It would take about .5 work hour to modify the cyclic stick lock at $85 per work hour with no cost for parts. This results in a total estimated cost of $43 per helicopter and $17,680 for the fleet.

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.

Page 2225

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.

Regulatory Findings

We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed, I certify this proposed regulation:

  1. Is not a ``significant regulatory action'' under Executive Order 12866;

  2. Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);

  3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and

  4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

    We prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.
