Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Eagle Aircraft (Malaysia) Sdn. Bhd. (Eagle) Model 150B airplanes. This proposed AD would require you to modify the canard rear spar and the rear spar attachment bracket. This proposed AD is the result of mandatory continuing Start Printed Page 37103airworthiness information (MCAI) issued by the airworthiness authority for Australia. The type design responsibility has been transferred from Australia to Malaysia since the release of the MCAI. The actions specified by this proposed AD are intended to prevent detachment of the rear spar bracket from the canard rear spar, which could result in failure of the canard rear spar. Such failure could lead to loss of control of the airplane.

DATES:

The Federal Aviation Administration (FAA) must receive any comments on this proposed rule on or before July 25, 2003.

ADDRESSES:

Submit comments to FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2000-CE-23-AD, 901 Locust, Room 506, Kansas City, Missouri 64106. You may view any comments at this location between 8 a.m. and 4 p.m., Monday through Friday, except Federal holidays. You may also send comments electronically to the following address: 9-ACE-7-Docket@faa.gov. Comments sent electronically must contain “Docket No. 2000-CE-23-AD” in the subject line.

Discussion

What Events Have Caused This Proposed AD?

The Civil Aviation Safety Authority (CASA), which is the airworthiness authority for Australia, notified FAA that an unsafe condition may exist on certain Eagle Model 150B airplanes. The CASA reports that the rear spar attachment bracket does not meet required strength specifications for installation on composite airplanes. These strength specifications are necessary to ensure that the rear spar does not detach from the canard rear spar.

The manufacturer has redesigned these parts in order meet required strength specifications.

What Are The Consequences if the Condition Is Not Corrected?

This condition, if not corrected, could result in failure of the canard rear spar. Failure of the canard rear spar could result in failure of the canard and loss of control of the airplane.

Is There Service Information That Applies to This Subject?

Eagle has issued Service Bulletin No. 1074, Revision 1, dated October 19, 1999.

What Are The Provisions of This Service Information?

The service bulletin includes procedures for:

—Trimming the rear spar bracket;

—Smoothing the transition surface for preparation of layups;

—Applying additional plies;

—Replacing the console support bracket and Vinikor cap; and

—Bonding on additional brackets.

What Action Did CASA Take?

The CASA classified this service bulletin as mandatory and issued Australian AD No. X-TS/3, dated December 24, 2000, in order to assure the continued airworthiness of these airplanes in the Australia.

Was This in Accordance With the Bilateral Airworthiness Agreement?

The affected airplanes were manufactured in Australia 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.

Pursuant to this bilateral airworthiness agreement, CASA had kept FAA informed of the situation described above.

The FAA's Determination and an Explanation of the Provisions of This Proposed AD

What Has FAA Decided?

The FAA has examined the findings of the CASA; reviewed all available information, including the service information referenced above; and determined that:

—The unsafe condition referenced in this document exists or could develop on other Eagle Model 150B airplanes of the same type design that are on the U.S. registry;

—The actions specified in the previously-referenced service information should be accomplished on the affected airplanes; and

—AD action should be taken in order to correct this unsafe condition.

What Would This Proposed AD Require?

This proposed AD would require you to incorporate the actions in the previously-referenced service bulletin.

How Does the Revision to 14 CFR Part 39 Affect This Proposed AD?

On July 10, 2002, FAA 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 special flight permits, alternative methods of compliance, and altered products. 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. Start Printed Page 37104

Cost Impact

How Many Airplanes Would This Proposed AD Impact?

We estimate that this proposed AD affects 7 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 accomplish this proposed modification:

Labor costParts costTotal cost per airplaneTotal cost on U.S. operators
4 workhours × $60 per hour = $240$135 per airplane$240 + $135 = $375 per airplane$375 × 7 = $2,625.

The proposed modification to the rear spar and the rear spar attachment bracket would require 25 hours for cure and post cure time.

Regulatory Impact

Would This Proposed AD Impact Various Entities?

The regulations proposed herein 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. Therefore, it is determined that this proposed rule would not have federalism implications under Executive Order 13132.

Would This Proposed AD Involve a Significant Rule or Regulatory Action?

For the reasons discussed above, I certify that this proposed action (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated, 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. A copy of the draft regulatory evaluation prepared for this action has been placed in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
