Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for all Pacific Aerospace Corporation, Ltd. (Pacific Aerospace) Model 750XL airplanes. This proposed AD would require you to replace any type TLP-D or TLED rivets on the aileron pushrod ends and elevator control pushrod ends. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand. We are issuing this proposed AD to replace the above identified rivets on the aileron pushrod ends and elevator control pushrod ends, which, if not replaced, could result in loose mechanical elements in the control systems. This could lead to control anomalies and loss of airplane control.

DATES:

We must receive any comments on this proposed AD by December 27, 2004.

Discussion

What events have caused this proposed AD? The Civil Aviation Authority (CAA), which is the airworthiness authority for New Zealand, recently notified FAA that an unsafe condition may exist on all Pacific Aerospace Corporation, Ltd. (Pacific Aerospace) Model 750XL airplanes. The CAA reports occurrences of loose type TLP-D or TLED rivets on the aileron pushrod ends and elevator control pushrod ends on Model 750XL airplanes in service in New Zealand.

What is the potential impact if FAA took no action? Any type TLP-D or TLED rivets on the aileron pushrod ends and elevator control pushrod ends could result in loose mechanical elements in the control systems. This could lead to control anomalies and loss of airplane control.

Is there service information that applies to this subject? Pacific Aerospace has issued Mandatory Service Bulletin No. PACSB/XL/007, dated June 22, 2004.

What are the provisions of this service information? The service bulletin includes procedures for:

—Inspecting for any type TLP-D or TLED rivets on the aileron pushrod ends and elevator control pushrod ends; and

—Replacing any type TLP-D or TLED rivets found on the aileron pushrod ends and elevator control pushrod ends with new Cherry Max 3213-4-2 or 3243-4-2 (oversize nominal 1/8-inch) rivets.

What action did the CAA take? The CAA classified this service bulletin as mandatory and issued New Zealand AD Number DCA/40XL/1, dated June 24, 2004, to ensure the continued airworthiness of these airplanes in New Zealand.

Did the CAA inform the United States under the bilateral airworthiness agreement? These Pacific Aerospace Model 750XL airplanes are manufactured in New Zealand and are type-certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement.

Under this bilateral airworthiness agreement, the CAA has kept us informed of the situation described above.

FAA's Determination and Requirements of This Proposed AD

What has FAA decided? We have examined the CAA's findings, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States.

Since the unsafe condition described previously is likely to exist or develop on other Pacific Aerospace Model 750XL airplanes of the same type design that are registered in the United States, we are proposing AD action to replace any type TLP-D or TLED rivets on the aileron pushrod ends and elevator control pushrod ends, which, if not replaced, could result in loose mechanical elements in the control systems. This could lead to control anomalies and loss of airplane control.

What would this proposed AD require? This proposed AD would require you to replace any type TLP-D or TLED rivets on the aileron pushrod ends and elevator control pushrod ends.

How does the revision to 14 CFR part 39 affect this proposed AD? On July 10, 2002, we published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs FAA's AD system. This regulation now includes material that relates to altered products, special flight permits, and alternative methods of compliance. This material previously was included in each individual AD. Since this material is included in 14 CFR part 39, we will not include it in future AD actions.

Costs of Compliance

How many airplanes would this proposed AD impact? We estimate that Start Printed Page 67866this proposed AD affects 6 airplanes in the U.S. registry.

What would be the cost impact of this proposed AD on owners/operators of the affected airplanes? We estimate the following costs to do this proposed replacement of any type TLP-D or TLED rivets on the aileron pushrod ends and elevator control pushrod ends:

Labor costParts costTotal cost per airplaneTotal cost on U.S. Operators
6 workhours × $65 per hour = $390$37 for 100 Cherry Max 3213-4-2 or 3243-4-2 (oversize nominal 1/8-inch) rivets$427$427 × 6 = $3,562.

The Cherry Max 3213-4-2 or 3243-4-2 rivets are available in a specially sealed 100-count package. The costs above cover this 100-count package although you may need less than 100 rivets.

Regulatory Findings

Would this proposed AD impact various entities? 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.

Would this proposed AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this proposed AD:

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 summary of the costs to comply with this proposed AD and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include “AD Docket FAA-2004-19444; Directorate Identifier 2004-CE-33-AD” in your request.

This proposed rulemaking is promulgated under the authority in Subtitle VII, Part A, Subpart III, Section 44701, General requirements. Under that section, the FAA is charged with prescribing minimum standards required in the interest of safety for the design of aircraft. This proposed regulation is within the scope of that authority since it corrects an unsafe condition in the design of the aircraft caused by type TLP-D or TLED rivets, which, if not replaced, could result in loose mechanical elements in the control systems. This could lead to control anomalies and loss of airplane control.
