Airworthiness Directives; BAE Systems (Operations) Limited (Jetstream) Model 4101 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION: Final rule.
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This AD requires repetitive detailed and specialized inspections to detect fatigue damage in the fuselage, replacement of certain bolt assemblies, and corrective actions if necessary. This AD results from a review of primary airframe fatigue test results and a Maintenance Steering Group 3 (MSG-3) analysis. We are issuing this AD to detect and correct fatigue damage of the fuselage, door, engine nacelle, empennage, and wing structures, which could result in reduced structural integrity of the airplane.
DATES: Effective August 30, 2005.
The Director of the Federal Register approved the incorporation by reference
[[Page 43026]]
of a certain publication listed in the AD as of August 30, 2005.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the AD docket on the Internet at http://www.dms.dot.gov or in person at the Docket Management Facility office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647- 5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. That NPRM was published in the Federal Register on May 9, 2005 (70 FR 24326). That NPRM proposed to require repetitive detailed and specialized inspections to detect fatigue damage in the fuselage, replacement of certain bolt assemblies, and corrective actions if necessary.
Comments
We provided the public the opportunity to participate in the development of this AD. We received no comments on the NPRM or on the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
The following table provides the estimated costs for U.S. operators to comply with this AD.
Estimated Costs
Cost per Number of Average

57 Up to $51,870, per inspection cycle. Inspections of the wing structure......
24
65 None......................
1,560
57 Up to $88,920, per inspection cycle.
In summary, required actions will take about 223 work hours per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is up to $826,215, or $14,495 per airplane, per inspection cycle.
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 AD will not have federalism implications under Executive Order 13132. This AD 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.
For the reasons discussed above, I certify that this AD:
(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.
We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
Adoption of the Amendment
0 Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0 1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0 2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
[[Page 43027]]
adding the following new airworthiness directive (AD):
2005-15-11 BAE Systems (Operations) Limited (Formerly British Aerospace Regional Aircraft): Amendment 39-14200. Docket No. FAA- 2005-21137; Directorate Identifier 2002-NM-86-AD.
Effective Date
(a) This AD becomes effective August 30, 2005.
Affected ADs
(b) None.
Applicability: (c) This AD applies to all BAE Systems (Operations) Limited Model Jetstream 4101 airplanes, certificated in any category.
Unsafe Condition
(d) This AD was prompted by a review of primary airframe fatigue test results and a Maintenance Steering Group 3 (MSG-3) analysis. We are issuing this AD to detect and correct fatigue damage of the fuselage, door, engine nacelle, empennage, and wing structures, which could result in reduced structural integrity of the airplane.
Compliance: (e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Service Bulletin Reference
(f) The term ``the service bulletin,'' as used in this AD, means BAE Systems (Operations) Limited Service Bulletin J41-51-001, Revision 2, dated April 30, 2003.
Inspection and Corrective Actions
(g) At the compliance times specified in the ``Initial Compliance Time'' column of Tables 1, 2, 3, 4, and 5 of this AD: Do the applicable detailed inspections and specialized inspections to detect fatigue damage, and replacement of certain bolt assemblies, and any applicable corrective actions, in accordance with the Accomplishment Instructions of the service bulletin. Do any corrective action before further flight. Repeat the inspections and replacement thereafter at intervals specified in the ``Repetitive Intervals'' column of Tables 1, 2, 3, 4, and 5 of this AD.
Note 1: For the purposes of this AD, a detailed inspection is: ``An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirrors, magnifying lenses, etc. may be necessary. Surface cleaning and elaborate procedures may be required.''
