Airworthiness Directives; Gulfstream Aerospace LP (Type 
Certificate Previously Held by Israel Aircraft Industries, Ltd.) Model 
Galaxy and Gulfstream 200 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as: Extension of airbrakes above 360 KIAS [knots indicated 
air speed]/0.79 Mi [Mach indicated] results in aerodynamic 
driven vibration of the airbrake which, if not limited per Revision 14 
to the AFM [airplane flight manual], can lead to high cycle fatigue 
failure of the airbrake in board hinge. The unsafe condition is high 
cycle fatigue of the airbrake in-board hinge, which can result in loss 
of the airbrake, which in turn can lead to reduced controllability of 
the airplane. The proposed AD would require actions that are intended 
to address the unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by August 9, 2010.

Discussion

    The Civil Aviation Authority of Israel (CAAI), which is the 
aviation authority for Israel, has issued Israeli Airworthiness 
Directive 01-10-01-07R1, dated January 20, 2010 (referred to after this 
as ``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Extension of airbrakes above 360 KIAS [knots indicated air 
speed]/0.79 Mi [Mach indicated] results in aerodynamic 
driven vibration of the airbrake which, if not limited per Revision 
14 to the AFM [airplane flight manual], can lead to high cycle 
fatigue failure of the airbrake in board hinge.

The unsafe condition is high cycle fatigue of the airbrake in-board 
hinge, which can result in loss of the airbrake, which in turn can lead 
to reduced controllability of the airplane. The required action 
includes revising the Limitations section of the Gulfstream 200 
Airplane Flight Manual to prohibit deploying the air brakes above the 
stated speed. You may obtain further information by examining the MCAI 
in the AD docket.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information

[[Page 36297]]

referenced above. We are proposing this AD because we evaluated all 
pertinent information and determined an unsafe condition exists and is 
likely to exist or develop on other products of the same type design.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 90 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $7,650, or $85 per product.

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 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 this 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 and placed it in the AD docket.

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 AD:

Gulfstream Aerospace LP (Type Certificate Previously Held by Israel 
Aircraft Industries, Ltd.): Docket No. FAA-2010-0555; Directorate 
Identifier 2010-NM-053-AD.

Comments Due Date

    (a) We must receive comments by August 9, 2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Gulfstream Aerospace LP (Type Certificate 
previously held by Israel Aircraft Industries, Ltd.) Model Galaxy 
and Gulfstream 200 airplanes, all serial numbers, certificated in 
any category.

Subject

    (d) Air Transport Association (ATA) of America Code 27: Flight 
controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    Extension of airbrakes above 360 KIAS [knots indicated air 
speed]/0.79 Mi [Mach indicated] results in aerodynamic 
driven vibration of the airbrake which, if not limited per Revision 
14 to the AFM [airplane flight manual], can lead to high cycle 
fatigue failure of the airbrake in board hinge.

The unsafe condition is high cycle fatigue of the airbrake in-board 
hinge, which can result in loss of the airbrake, which in turn can 
lead to reduced controllability of the airplane.

Compliance

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Actions

    (g) Within 60 days after the effective date of this AD: Revise 
the Limitations section of the Gulfstream 200 Airplane Flight Manual 
(AFM) to include the following statement. This may be done by 
inserting a copy of this AD into the AFM.

``MAXIMUM AIR BRAKES OPERATION/EXTENDED SPEED

360 KIAS/0.79 Mi

NOTE

    During emergency, air brakes may be used at speeds above 0.79 
Mi.''

    Note 1: When a statement identical to that in paragraph (g) of 
this AD has been included in the general revisions of the AFM, the 
general revisions may be inserted into the AFM, and the copy of this 
AD may be removed from the AFM.

    Note 2: The Gulfstream 200 AFM applies to both the Model Galaxy 
and Gulfstream 200 airplanes.

FAA AD Differences

    Note 3:  This AD differs from the MCAI and/or service 
information as follows: No differences.

Other FAA AD Provisions

    (h) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA,
