Discussion
The FAA has received information regarding a quality control problem on Relative Workshop vector parachute systems. A loose amp fitting on the breakaway housing was found during packing of one of these Relative Workshop vector parachute systems. Further analysis reveals that the amp fittings on the end of the stainless steel breakaway housing were improperly swaged. This problem could exist on any of the 2,127 Relative Workshop vector parachute system that were manufactured between January 1, 1996, and September 10, 1998.
This condition, if not detected and corrected in a timely manner, could result in an unintentional partial breakaway of the main chute and interference with deployment of the reserve parachute.
Relevant Service Information
Relative Workshop has issued Product Service Bulletin #091098-B, dated September 10, 1998, which specifies procedures for inspecting the amp fittings on the end of the breakaway housing for proper swaging, and re-swaging any incorrectly swaged fittings using the Nicopress or Swage-It swaging tool.
The FAA's Determination
After examining the circumstances and reviewing all available information related to the incident described above, including the above-referenced service information, the FAA has determined that AD action should be taken to prevent the amp fittings from coming off the stainless steel breakaway housing, which could result in an unintentional partial breakaway of the main chute and interference with the deployment of the reserve parachute.
Explanation of the Provisions of the AD
Since an unsafe condition has been identified that is likely to exist or develop in other The Uninsured Relative Workshop Inc. vector parachute systems that were manufactured between January 1, 1996, and September 10, 1998, the FAA is issuing an AD. This AD requires inspecting the amp fittings on the end of the breakaway housing for proper swaging, and re-swaging any incorrectlyswaged fittings using the Nicopress or Swage-It swaging tool. Accomplishment of the actions specified in this AD is required in accordance with Relative Workshop Product Service Bulletin #091098-B, dated September 10, 1998.
Determination of the Effective Date of the AD
Since a situation exists that requires the immediate adoption of this regulation, it is found that notice and opportunity for public prior comment hereon are impracticable, and that good cause exists for making this amendment effective in less than 30 days.
Comments Invited
Although this action is in the form of a final rule that involves requirements affecting immediate flight safety and, thus, was not preceded by notice and opportunity to 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 addressspecified above. 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, both before and after the closing date for comments, 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 comments submitted in response to this rule must submit a self-addressed, stamped postcard on which thefollowing statement is made: "Comments to Docket No. 98-CE-101-AD." The postcard will be date stamped and returned to the commenter.
Regulatory Impact
The regulations adopted herein will not have substantial direct effects 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, in accordance with Executive Order 12612, it is determined that this final rule does not have sufficient federalism implications to warrant the preparation of a Federalism Assessment.
The FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in parachutes, and 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 (otherwise, an evaluation is not required). A copy of it, if filed, may be obtained from the Rules Docket.
