02-10649. Airworthiness Directives; Eurocopter France Model AS332L2 Helicopters

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

This amendment adopts a new airworthiness directive (AD) for Eurocopter France (ECF) Model AS332L2 helicopters. This action requires, before further flight, verifying that the air vent is installed on the inflation cylinder of each life raft assembly. If the air vent is missing, this AD also requires replacing the cylinder head with an airworthy part before further flight. This amendment is prompted by the discovery that an inflation cylinder in the life raft did not have an air vent installed. This condition, if not corrected, could result in inadvertent life raft inflation, loss of the life raft, contact with the main or tail rotor, and subsequent loss of control of the helicopter.

DATES:

Effective May 17, 2002.

Comments for inclusion in the Rules Docket must be received on or before July 1, 2002.

ADDRESSES:

Submit comments in triplicate to the Federal Aviation Administration (FAA), Office of the Regional Counsel, Southwest Region, Attention: Rules Docket No. 2002-SW-04-AD, 2601 Meacham Blvd., Room 663, Fort Worth, Texas 76137. You may also send comments electronically to the Rules Docket at the following address: [e-mail].

SUPPLEMENTARY INFORMATION:

The Direction Generale De L'Aviation Civile (DGAC), the airworthiness authority for France, notified the FAA that an unsafe condition may exist on ECF Model AS332L2 helicopters. The DGAC advises of the discovery of a missing air vent on the head of the inflation cylinder of a life raft. Absence of an air vent on the cylinder head might lead to inadvertent life raft inflation and cause the life raft to be lost and to come into contact with the main or tail rotor.

ECF has issued Alert Telex No. 25.01.06, dated September 17, 2001, which specifies checking that the air vent is installed on the heads of the cylinders of the life raft assemblies. The DGAC classified this service bulletin as mandatory and issued AD 2001-500-019(A), dated October 17, 2001, to ensure the continued airworthiness of these helicopters in France.

This helicopter model is manufactured in France and is type certificated for operation in the United States under the provisions of 14 CFR 21.29 and the applicable bilateral agreement. Pursuant to the applicable bilateral agreement, the DGAC has kept the FAA informed of the situation described above. The FAA has examined the findings of the DGAC, reviewed all available information, and determined that AD action is necessary for products of this type design.

This unsafe condition is likely to exist or develop on other helicopters of the same type design registered in the United States. Therefore, this AD is being issued to prevent inadvertent life raft inflation, loss of the life raft, contact with the main or tail rotor, and subsequent loss of control of the helicopter. This AD requires, before further flight, verifying that the air vent is installed on the head of the inflation cylinders of each life raft. If the air vent is missing, this AD also requires replacing the cylinder head with an airworthy part before further flight. Replacing the cylinder head or verifying that the air vent is installed on the heads of the inflation cylinder is terminating action for the requirements of this AD.

None of the Model AS332L2 helicopters affected by this action are on the U.S. Register. All helicopters included in the applicability of this rule are currently operated by non-U.S. operators under foreign registry; therefore, they are not directly affected by this AD action. However, the FAA considers that this rule is necessary to ensure that the unsafe condition is addressed in the event that any of these subject helicopters are imported and placed on the U.S. Register in the future.

Should an affected helicopter be imported and placed on the U.S. Register in the future, it would require approximately 1/2 work hour to accomplish the required actions, at an average labor rate of $60 per work hour. Based on these figures, the cost impact of this AD would be $30 per helicopter.

Since this AD action does not affect any helicopter that is currently on the U.S. register, it has no adverse economic impact and imposes no additional burden on any person. Therefore, notice and public procedures hereon are unnecessary and the amendment may be made effective in less than 30 days after publication in the Federal Register.

Comments Invited

Although this action is in the form of a final rule that involves requirements affecting flight safety and, thus, was not preceded by notice and an opportunity for public comment, comments are invited on this rule. Interested persons are invited to comment on this rule by submitting such written data, views, or arguments as they may desire. Communications should identify the Rules Docket number and be submitted in triplicate to the address specified under the caption ADDRESSES. All communications received on or before the closing date for comments will be considered, and this rule may be amended in light of the comments received. Factual information that supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether additional rulemaking action would be needed.

Comments are specifically invited on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify the rule. All comments submitted will be available in the Rules Docket for examination by interested persons. A report that summarizes each FAA-public contact concerned with the substance of this AD will be filed in the Rules Docket.

Commenters wishing the FAA to acknowledge receipt of their mailed comments submitted in response to this rule must submit a self-addressed, stamped postcard on which the following statement is made: “Comments to Docket No. 2002-SW-04-AD.” The postcard will be date stamped and returned to the commenter.

The regulations adopted herein will 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132.

The FAA has 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. The FAA has 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 Rules Docket. A copy of it, if filed, may be obtained from the Rules Docket at the location provided under the caption ADDRESSES.
