SUPPLEMENTARY INFORMATION:

Comments Invited

We invite you to send any written relevant data, views, or arguments regarding this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number, “FAA-2007-29317; Directorate Identifier 2007-CE-079-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the proposed AD. We will consider all comments received by the closing date and may amend the proposed AD in light 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 we receive concerning this proposed AD.

Discussion

We have been notified by Ballistic Recovery Systems, Inc. of a concern similar to that which prompted AD 2007-14-03, dated August 16, 2007, on the Cirrus Airplane Parachute System (CAPS), where the parachute failed to successfully deploy. Testing indicates that the force of the rocket ignition and rocket blast may prematurely break the nylon pick up collar/support screws. When functioning properly the screws should not break until impacted by a flange at the rocket base. A prematurely separated collar/support may bind on the rocket as it slides down toward the flange at the base of the rocket. This may alter the direction of the rocket.

This condition, if not corrected, could result in the parachute failing to successfully deploy upon activation.

Relevant Service Information

We have reviewed Ballistic Recovery Systems, Inc. Service Bulletins SB 07-01, dated June 8, 2007; and SB 07-02, dated June 8, 2007. The service information describes procedures for the replacement of the pick-up collar support and screws.

FAA's Determination and Requirements of the Proposed AD

We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would require the replacement of the pick-up collar support and screws for the BRS-172 and BRS-182 Parachute System.

The BRS-172 and BRS-182 Parachute System could also be installed on Cessna 150 series airplanes and Symphony Aircraft Industries Models OMF-100-160 and SA 160 airplanes. The corrective actions proposed in this NPRM are specific to the Cessna 172 and 182 series airplanes. We are evaluating these other BRS installations and, based on this evaluation, may consider additional rulemaking on this subject.

Costs of Compliance

We estimate that this proposed AD would affect 54 airplanes in the U.S. registry.

We estimate the following costs to do the proposed modification:

Note:

BRS will provide warranty credit to the extent noted in Ballistic Recovery Systems, Inc. Service Bulletins SB 07-01 and SB 07-02, both dated June 8, 2007.

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.

Regulatory Findings

We have 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 above, I certify that the 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); and

3. 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 a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Examining the AD Docket

You may examine the AD docket that contains the proposed AD, the regulatory evaluation, any comments received, and other information on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647-5527) is located at the street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
