The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register.

Federal Aviation Administration, DOT.
This amendment adopts a new airworthiness directive (AD) that applies to certain Eagle Aircraft (Malaysia) Sdn. Bhd. (Eagle) Model 150B airplanes. This AD requires you to modify the canard rear spar and the rear spar attachment bracket. This AD is the result of mandatory continuing airworthiness 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 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.
This AD becomes effective on November 3, 2003.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of November 3, 2003.
You may get the service information referenced in this AD from Eagle Aircraft (Malaysia) Sdn. Bhd., Composites Technology City, Batu Barendam Airport, 75350 Batu Barendam, Melaka, Malaysia. You may view this information at the Federal Aviation Administration (FAA), Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2000-CE-23-AD, 901 Locust, Room 506, Kansas City, Missouri 64106; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.Start Further Info

What Events Have Caused This 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 bracket does not detach from the canard rear spar.
The manufacturer has redesigned these parts in order to meet required strength specifications.
What Is the Potential Impact if FAA Took No Action?
This condition, if not corrected, could result in failure of the canard rear spar. Failure of the canard rear spar could result in loss of control of the airplane.
Has FAA Taken Any Action to This Point?
We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Eagle Model 150B airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on June 23, 2003 (68 FR 37102). The NPRM proposed to require you to modify the canard rear spar and the rear spar attachment bracket.
Was the Public Invited To Comment?
The FAA encouraged interested persons to participate in the making of this amendment. We did not receive any comments on the proposed rule or on our determination of the cost to the public.
What Is FAA's Final Determination on This Issue?
After careful review of all available information related to the subject presented above, we have determined that air safety and the public interest require the adoption of the rule as proposed except for minor editorial corrections. We have determined that these minor corrections:
—Provide the intent that was proposed in the NPRM for correcting the unsafe condition; and
—Do not add any additional burden upon the public than was already proposed in the NPRM.
How Does the Revision to 14 CFR Part 39 Affect This 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.
How Many Airplanes Does This AD Impact?
We estimate that this AD affects 7 airplanes in the U.S. registry.
What Is the Cost Impact of This AD on Owners/Operators of the Affected Airplanes?
We estimate the following costs to accomplish the modification:
|Labor cost||Parts cost||Total cost per airplane||Total cost on U.S. operators|
|4 workhours × $60 per hour = $240||$135 per airplane||$240 + $135 = $375 per airplane||$375 × 7 = $2,625.|
The modification to the rear spar and the rear spar attachment bracket will require 25 hours for cure and post cure time.
Does This AD Impact Various Entities?
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.
Does This AD Involve a Significant Rule or Regulatory Action?
For the reasons discussed above, I certify that this 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) 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 final evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.Start List of Subjects
