Airworthiness Directives; Gulfstream Model G-1159, G-1159A, G-
1159B, and G-IV Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Gulfstream Model G-1159, G-1159A, G-1159B, and G-IV series airplanes. 
This AD requires a one-time inspection of the left and right aileron 
and elevator

[[Page 61306]]

actuators to determine the part and serial numbers of each actuator, 
repetitive inspections of suspect actuators to detect broken damper 
shafts, and replacement of any actuator having a broken damper shaft. 
This AD also requires that operators report any broken damper shaft 
they find to the FAA. This AD also provides an optional terminating 
action for the repetitive inspection requirements of this AD. This AD 
is prompted by reports of broken or cracked damper shafts within the 
aileron and elevator actuator assemblies. We are issuing this AD to 
detect and correct broken damper shafts, which could result in locking 
of an aileron or elevator actuator (hard-over condition), subsequent 
loss of aileron or elevator control, and consequent reduced 
controllability of the airplane.

DATES: Effective November 2, 2004.
    The incorporation by reference of certain publications listed in 
the AD is approved by the Director of the Federal Register as of 
November 2, 2004.
    We must receive comments on this AD by December 17, 2004.

Docket Management System (DMS)

    The FAA has implemented new procedures for maintaining AD dockets 
electronically. As of May 17, 2004, new AD actions are posted on DMS 
and assigned a docket number. We track each action and assign a 
corresponding directorate identifier. The DMS AD docket number is in 
the form ``Docket No. FAA-2004-99999.'' The Transport Airplane 
Directorate identifier is in the form ``Directorate Identifier 2004-NM-
999-AD.'' Each DMS AD docket also lists the directorate identifier 
(``Old Docket Number'') as a cross-reference for searching purposes.

Examining the Dockets

    You can examine the AD docket on the Internet at http://
<a href="http://dms.dot.gov">dms.dot.gov</a>, 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 DOT 
street address stated in the ADDRESSES section. Comments will be 
available in the AD docket shortly after the DMS receives them.

SUPPLEMENTARY INFORMATION: We have received a report from the airplane 
manufacturer, Gulfstream, that the damper shafts in two actuators broke 
under normal torquing requirements during assembly of the actuators for 
a Gulfstream Model GV-SP airplane. Approximately one week after the 
original occurrence, a third actuator was found with a cracked damper 
shaft. In each case, the cracks originated at the threaded base of the 
damper shaft. In addition, the third actuator was found to be from a 
manufacturing lot previous to that of the other two actuators. Parker 
Aerospace, the actuator manufacturer, notified Gulfstream that the 
production process used after 1998 to manufacture aileron and elevator 
actuator damper shafts (internal to the actuator) may induce cracks in 
the threaded portion of the shaft. This cracking could cause the 
retaining nut and the separated portion of the failed damper shaft to 
become dislodged from the damper body and block the movement of the 
assembly. This condition, if not corrected, could result in locking of 
an aileron or elevator actuator (hard-over condition), subsequent loss 
of aileron or elevator control, and consequent reduced controllability 
of the airplane.
    The affected aileron and elevator actuators installed on Gulfstream 
Model G-1159, G-1159A, G-1159B, G-IV, and GV series airplanes, are 
identical to those installed on Model GV-SP airplanes. Therefore, all 
of these models may be subject to the identified unsafe condition.

Other Rulemaking for Additional Airplane Models

    Operators should note that, as we explained previously, Gulfstream 
Model GV and GV-SP series airplanes are subject to the same unsafe 
condition addressed in this AD. We are currently considering additional 
rulemaking to address the unsafe condition for those airplanes. 
However, because the unsafe condition is less severe for those models, 
the planned compliance time for that action would allow enough time to 
provide notice and opportunity for prior public comment on the merits 
of the corrective actions.

Relevant Service Information

    We have reviewed the following Gulfstream alert customer bulletins:

[[Page 61307]]

    The alert customer bulletins describe procedures for a one-time 
inspection of the left and right aileron and elevator actuators to 
determine the part number (P/N) and serial number (S/N) of each 
actuator. The alert customer bulletins also describe procedures for an 
inspection of the actuators with certain P/Ns and S/Ns to detect broken 
damper shafts, and replacement of any actuator having a broken damper 
shaft with a new or serviceable actuator.

FAA's Determination and Requirements of This AD

    The unsafe condition described previously is likely to exist or 
develop on other airplanes of the same type design. Therefore, we are 
issuing this AD to detect and correct broken damper shafts, which could 
result in locking of an aileron or elevator actuator (hard-over 
condition), subsequent loss of aileron or elevator control, and 
consequent reduced controllability of the airplane. This AD requires 
accomplishing the actions specified in the service information 
described previously, except as discussed under ``Differences Between 
the AD and Alert Customer Bulletins.'' This AD also requires that 
operators report any broken damper shafts found during the initial and 
repetitive inspections required by paragraph (h) of this AD to the FAA.

Differences Between the AD and Alert Customer Bulletins

    The alert customer bulletins do not specify the type of inspection 
to use to determine the P/N and S/N of the actuators. We have 
determined that the location of the actuators will require access and 
possibly additional inspection aides, and therefore, this AD requires a 
general visual inspection to determine the P/N and S/N of the 
actuators. We have included the definition of a general visual 
inspection in this AD.
    The alert customer bulletins do not specify what to do if an 
installed actuator either has a P/N and/or S/N that is missing or is 
unreadable. This AD requires that those actuators be inspected to 
detect broken damper shafts--as if they have a P/N and S/N listed in 
the alert customer bulletin.
    The alert customer bulletins recommend a one-time inspection of the 
aileron and elevator actuators for broken damper shafts. However, a 
suspect damper shaft found undamaged during the initial inspection 
still has the potential to break at some time in the future. Because a 
one-time inspection alone would not provide the degree of safety 
necessary, we have determined that repetitive inspections of the 
suspect actuators are necessary to ensure an adequate level of safety 
for the affected transport airplane fleet. We have also determined that 
an interval of 500 flight hours or 12 months, whichever is first, is an 
appropriate compliance time for the repetitive inspections. Although 
the alert customer bulletins do not include repetitive inspections, 
they do note that a recurring inspection will be added to the 
applicable airplane maintenance manual.
    The alert customer bulletins also do not specify the type of 
inspection to use to detect broken damper shafts. We have determined 
that a detailed inspection for this action is appropriate; we have 
included the definition of this inspection in this AD. Therefore, this 
AD requires a detailed inspection to detect broken damper shafts. We 
have included the definition of a detailed inspection in this AD.
    The alert customer bulletins specify replacing an actuator having a 
broken damper shaft, but they do not specify with what type of 
replacement actuator. This AD requires replacement with either:
    <bullet> A new or serviceable actuator having a subject P/N and S/N 
listed in the alert customer bulletin, provided it has been inspected 
for broken damper shafts in accordance with the requirements of this 
AD; or
    <bullet> A new or serviceable actuator having a P/N and/or S/N 
different than those listed in the alert customer bulletin. Replacing 
an actuator with an actuator having a different P/N and/or S/N 
terminates the requirements of this AD for that actuator only.
    We are not requiring the terminating action (i.e., replacement of 
all suspect actuators) at this time, because we have determined, and 
the actuator manufacturer has confirmed, that the necessary replacement 
actuators (with a P/N and/or S/N not listed in the applicable alert 
customer bulletin) are not yet available and will not be available for 
another 24 to 36 months. Therefore, we are providing the terminating 
action as an option for operators once those parts become available.
    The alert customer bulletins do not recommend that findings of 
broken damper shafts be reported. This AD requires findings of all 
broken damper shafts be reported to the FAA. When the unsafe condition 
addressed by an AD is likely due to a manufacturer's quality control 
(QC) problem, a reporting requirement is instrumental in ensuring that 
we can gather as much information as possible regarding the extent and 
nature of the QC problem or breakdown, especially in cases where the 
data may not be available through other established means. This 
information is necessary to ensure that proper corrective action will 
be taken. Based on the results of these reports, we may determine that 
further corrective action is warranted.
    The Accomplishment Instructions of the referenced alert customer 
bulletins specify to submit the Service Reply Card or compliance 
information to the manufacturer. This AD does not include those 
actions; we do not need this information from operators.

Clarification of Applicability

    The effectivities of the alert customer bulletins include all Model 
G-1159, G-1159A, G-1159B, and G-IV series airplanes, equipped with 
aileron or elevator actuators having certain P/Ns and S/Ns. Because 
there is no way to determine if an actuator with a suspect P/N and S/N 
is installed without inspecting the airplane, this AD applies to all 
Model G-1159, G-1159A, G-1159B, and G-IV series airplanes. We would, 
however, point out that the first action in the alert customer 
bulletins is an inspection to determine if an actuator having a certain 
P/N and S/N is installed.

Interim Action

    This AD is considered to be interim action. The inspection reports 
that are required by this AD will enable us to obtain better insight 
into the nature and extent of the broken damper shafts, and eventually 
to develop final action to address the unsafe condition. Once final 
action has been developed and replacement parts are available, we may 
consider further rulemaking.

Changes to 14 CFR Part 39/Effect on the AD Relating to Special Flight 
Permits

    On July 10, 2002, the FAA issued a new version of 14 CFR part 39 
(67 FR 47997, July 22, 2002), which governs the FAA's airworthiness 
directives system. The regulation now includes material that relates to 
altered products, special flight permits, and alternative methods of 
compliance (AMOC). This material is included in part 39, except that 
the office authorized to approve AMOCs is identified in each individual 
AD.
    However, as amended, part 39 provides for the FAA to add special 
requirements for operating an airplane to a repair facility to do the 
work required by an airworthiness directive. For purposes of this AD, 
we have determined that such a special flight permit is prohibited.

[[Page 61308]]

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD; therefore, providing notice and opportunity for public comment 
before the AD is issued is impracticable, and good cause exists to make 
this AD effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements that affect 
flight safety and was not preceded by notice and an opportunity for

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 the 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 AD. See the ADDRESSES section for a location to 
examine the regulatory evaluation.

Inspection To Determine Actuator Part and Serial Numbers

    (g) Within 50 flight hours after the effective date of this AD, 
do a one-time general visual inspection of the left and right 
aileron and elevator actuators to determine the part number (P/N) 
and serial number (S/N) of each actuator, in accordance with the 
applicable alert customer bulletin.

    Note 2: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''

Initial and Repetitive Actuator Inspections and Corrective Action

    (h) For any actuator identified during the inspection required 
by paragraph (g) of this AD with a P/N and S/N listed in the 
applicable alert customer bulletin, and for actuators for which the 
P/N and/or S/N were missing or unreadable: Before further flight, do 
a detailed inspection of each identified actuator to detect a broken 
damper shaft, in accordance with the applicable alert customer 
bulletin.

    Note 3: 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 
mirror, magnifying lenses, etc., may be necessary. Surface cleaning 
and elaborate procedures may be required.''

    (1) If no damper shaft is found broken: Repeat the inspection 
required by paragraph (h) of this AD thereafter at intervals not to 
exceed 500 flight hours or 12 months, whichever occurs first.
    (2) If any damper shaft is found broken: Before further flight, 
do the action specified in paragraph (h)(2)(i) or (h)(2)(ii) of this 
AD, in accordance with the applicable alert customer bulletin.
    (i) Replace the actuator with a new or serviceable actuator 
having a P/N and S/N listed in the applicable alert customer 
bulletin, provided the new or serviceable actuator has been 
inspected in accordance with the requirements of paragraph (h) of 
this AD. Thereafter, repeat the inspection required by paragraph (h) 
of this AD at intervals not to exceed 500 flight hours or 12 months, 
whichever occurs first.
    (ii) Replace the actuator with a new or serviceable actuator 
having a P/N and/or S/N not listed in the applicable alert customer 
bulletin. This replacement terminates the requirements of this AD 
for that actuator only.

Optional Terminating Action

    (i) Replacement of all suspect actuators with new or serviceable 
actuators having a P/N and/or S/N not listed in the applicable alert 
customer bulletin terminates the requirements of this AD.

Reporting Requirement

    (j) Submit a report of any broken damper shafts to the Manager, 
Atlanta Aircraft Certification Office (ACO), FAA, Small Airplane 
Directorate, One Crown Center, 1895 Phoenix Boulevard, suite 450, 
Atlanta, Georgia 30349; fax (770) 703-6097. The report must be done 
at the applicable time specified in paragraph (j)(1) or (j)(2) of 
this AD. The report must include the inspection date, the airplane 
model and S/N, the actuator position (left or right aileron or 
elevator), and the actuator P/N and S/N. Information collection 
requirements contained in this AD have been approved by the Office 
of Management and Budget (OMB) under the provisions of the Paperwork 
Reduction Act of 1980 (44 U.S.C. 3501 et seq.) and have been 
assigned OMB Control Number 2120-0056.
    (1) If the inspection required by paragraph (h) of this AD was 
done after the effective date of this AD: Submit the report within 
10 days after the inspection.
    (2) If the inspection required by paragraph (h) of this AD was 
done before the effective date of this AD: Submit the report within 
10 days after the effective date of this AD.

Parts Installation

    (k) As of the effective date of this AD, no person may install 
an aileron or elevator actuator having a P/N and S/N specified in 
the applicable alert customer bulletin, on any airplane, unless the 
actuator has been inspected according to paragraph (h) of this AD.

Special Flight Permit

    (l) Special flight permits (14 CFR 21.197 and 21.199) are not
