[Docket No. FAA-2005-21137; Directorate Identifier 2002-NM-86-AD]
RIN 2120-AA64


Airworthiness Directives; BAE Systems (Operations) Limited 
(Jetstream) Model 4101 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all BAE Systems (Operations) Limited (Jetstream) Model 4101 
airplanes. This proposed AD would require repetitive detailed and 
specialized inspections to detect fatigue damage in the fuselage, 
replacement of certain bolt assemblies, and corrective actions if 
necessary. This proposed AD is prompted by a review of primary airframe 
fatigue test results and Maintenance Steering Group 3 (MSG-3) analysis. 
We are proposing 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: We must receive comments on this proposed AD by June 8, 2005.

Discussion

    The Civil Aviation Authority (CAA), which is the airworthiness 
authority for the United Kingdom, notified us that an unsafe condition 
may exist on all BAE Systems (Operations) Limited (Jetstream) Model 
4101 airplanes. The CAA advises that, following an extensive review of 
the primary airframe fatigue test results and Maintenance Steering 
Group 3 (MSG-3) analysis for the Model 4101 airplanes, new areas and 
thresholds of fatigue damage were identified. New inspections and 
revisions to existing inspections for fatigue damage (requirements and 
inspection thresholds in particular) are needed to address the 
findings. These inspections are necessary to maintain the structural 
integrity of the airplane. Fatigue damage of the fuselage, door, engine 
nacelle, empennage, and wing structures, if not detected and corrected 
in a timely manner, could result in reduced structural integrity of the 
airplane.

Relevant Service Information

    BAE Systems (Operations) Limited has issued Service Bulletin J41-
51-001, Revision 2, dated April 30, 2003. The service bulletin 
describes procedures for repetitive detailed and specialized 
inspections of the fuselage to detect fatigue damage, replacement of 
the bolt assemblies of the pintle bearing housing and upper club foot 
fitting with new bolt assemblies, and corrective actions if necessary. 
The specialized inspections include eddy current inspections (including 
high frequency and rotating), radiographic inspections, a magnetic 
particle inspection, and a torque measurement. The areas to be 
inspected

[[Page 24327]]

are located in or around door, fuselage, engine nacelle, empennage, and 
wing structures. In addition, the service bulletins specify submitting 
inspection reports after most of the inspection procedures are 
completed. The corrective actions include replacing a damaged part with 
a new part, and repairing damage in accordance with the service 
bulletin, or in accordance with a method approved by BAE Systems 
(Operations) Limited if damage is outside specified limits. 
Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition. The CAA mandated 
the service information and issued British airworthiness directive 005-
02-2002 to ensure the continued airworthiness of these airplanes in the 
United Kingdom.

FAA's Determination and Requirements of the Proposed AD

    This airplane model is manufactured in the United Kingdom and is 
type certificated for operation in the United States under the 
provisions of Sec.  21.29 of the Federal Aviation Regulations (14 CFR 
21.29) and the applicable bilateral airworthiness agreement. Pursuant 
to this bilateral airworthiness agreement, the CAA has kept the FAA 
informed of the situation described above. We have examined the CAA's 
findings, evaluated all pertinent information, and determined that we 
need to issue an AD for products of this type design that are 
certificated for operation in the United States.
    Therefore, we are proposing this AD, which would require 
accomplishing the actions specified in the service information 
described previously, except as discussed under ``Differences Between 
the Proposed AD and the Service Bulletin.''

Differences Between the Proposed AD and the Service Bulletin

    Operators should note that, although the Accomplishment 
Instructions of the referenced service bulletin describes procedures 
for submitting inspection reports, this proposed AD would not require 
those actions. We do not need this information from operators.
    The service bulletin specifies that you may contact the 
manufacturer for instructions on how to repair certain conditions, but 
this proposed AD would require you to repair those conditions using a 
method that we or the CAA (or its delegated agent) approve. In light of 
the type of repair that would be required to address the unsafe 
condition, and consistent with existing bilateral airworthiness 
agreements, we have determined that, for this proposed AD, a repair we 
or the CAA approve would be acceptable for compliance with this 
proposed AD.

Grace Period

    Operators should note that, although the service bulletin does not 
list a grace period in the compliance times for some of the actions, 
this proposed AD adds a grace period to the compliance times. We find 
that a grace period will keep airplanes from being grounded 
unnecessarily.
    Also, although the service bulletin specifies a grace period for 
some actions, this proposed AD has a different grace period. We find 
that this modified grace period will keep airplanes from being grounded 
unnecessarily.

Clarification of Flight Cycle Terminology

    Operators should note that, although the Accomplishment 
Instructions of the referenced service bulletins use ``flights'' to 
define some compliance times, this proposed AD uses ``total flight 
cycles.''

Clarification of Inspection Terminology

    In this proposed AD, the ``detailed visual inspection,'' ``detailed 
internal visual inspection,'' ``detailed internal inspection,'' and 
``detailed external visual inspection'' specified in the service 
bulletin are referred to as a ``detailed inspection.'' We have included 
the definition for a detailed inspection in Note 1 of the proposed AD.

Clarification of Initial Inspection Threshold

    For airplanes not inspected previously, the service bulletin 
specifies inspection thresholds of 8 years and 4 years after first 
flight. However, for these same airplanes, paragraph (g) of this 
proposed AD specifies an inspection threshold of 96 months (8 years) 
and 48 months (4 years), as applicable, after the date of issuance of 
the original standard Airworthiness Certificate or the date of issuance 
of the original Export Certificate of Airworthiness. This decision is 
based on our determination that ``first flight'' may be interpreted 
differently by different operators. We find that our proposed 
terminology is generally understood within the industry and records 
will always exist that establish these dates with certainty.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this proposed AD.

                                                                     Estimated Costs

--------------------------------------------------------------------------------------------------------------------------------------------------------

    The total proposed actions would 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 total proposed 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 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.
    For the reasons discussed above, I certify that the proposed 
regulation:
    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 regulatory evaluation of the estimated costs to 
comply with this proposed AD. 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, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    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]

    2. The FAA amends Sec.  39.13 by adding the following new 
airworthiness directive (AD):

BAE Systems (Operations) Limited (Formerly British Aerospace 
Regional Aircraft): Docket No. FAA-2005-21137; Directorate 
Identifier 2002-NM-86-AD.

Comments Due Date

    (a) The Federal Aviation Administration must receive comments on 
this AD action by June 8, 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 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.''
