14 CFR Part 39

[Docket No. FAA-2007-27757; Directorate Identifier 2007-NM-030-AD; 
Amendment 39-15014; AD 2007-07-13]
RIN 2120-AA64

 
Airworthiness Directives; Gulfstream Aerospace LP Model Galaxy 
Airplanes and Model Gulfstream 200 Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This 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:

    Avionics and electrical wire harnesses are routed behind the 
Primary Flight Displays (PFD) tray at the rear of the instrument 
panel. In some cases, the wire harness has been found to be chafing 
on the PFD tray. That could result in electrical arcing and shorting 
and subsequent loss of systems essential for safe flight.

    This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

DATES: This AD becomes effective April 20, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of April 20, 
2007.
    We must receive comments on this AD by May 7, 2007.

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance 
of ADs related to MCAI. This streamlined process will allow us to adopt 
MCAI safety requirements in a more efficient manner and will reduce 
safety risks to the public. This process continues to follow all FAA AD 
issuance processes to meet legal, economic, Administrative Procedure 
Act, and Federal Register requirements. We also continue to meet our 
technical decision-making responsibilities to identify and correct 
unsafe conditions on U.S.-certificated products.
    This AD references the MCAI and related service information that we 
considered in forming the engineering basis to correct the unsafe 
condition. The AD contains text copied from the MCAI and for this 
reason might not follow our plain language principles.

Discussion

    The Civil Aviation Authority of Israel (CAAI), which is the 
aviation authority for Israel, has issued Israeli Airworthiness 
Directive 31-07-01-12, dated February 15, 2007 (referred to after this 
as ``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Avionics and electrical wire harnesses are routed behind the 
Primary Flight Displays (PFD) tray at the rear of the instrument 
panel. In some cases, the wire harness has been found to be chafing 
on the PFD tray. That could result in electrical arcing and shorting 
and subsequent loss of systems essential for safe flight.

    The corrective actions include inspecting the wiring harness for 
chafing, performing repairs if required; and inspecting the wire 
harnesses for

[[Page 16700]]

proper clearance, and rerouting/relocating wire harnesses to obtain 
proper clearance if required. You may obtain further information by 
examining the MCAI in the AD docket.

Relevant Service Information

    Gulfstream has issued Service Bulletin 200-31-301, dated January 
19, 2007. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This 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 referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between the 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 required 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 AD.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
avionics and electrical wire harnesses are routed behind the primary 
flight displays (PFD) tray at the rear of the instrument panel. In some 
cases, the wire harness has been found to be chafing on the PFD tray. 
That could result in electrical arcing and shorting and subsequent loss 
of systems essential for safe flight. Therefore, we determined that 
notice and opportunity for public comment before issuing this AD are 
impracticable and that good cause exists for making this amendment 
effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2007-27757; Directorate 
Identifier 2007-NM-030-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://dms.dot.gov
, including any personal information you provide. We will 

also post a report summarizing each substantive verbal contact we 
receive about this AD.

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 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 this AD:
    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 and placed it in the AD docket.

2. The FAA amends Sec.  39.13 by adding the following new AD:

2007-07-13 GULFSTREAM AEROSPACE LP (Formerly Israel Aircraft 
Industries, Ltd.): Amendment 39-15014. Docket No. FAA-2007-27757; 
Directorate Identifier 2007-NM-030-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective April 
20, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Gulfstream Model Galaxy airplanes and 
Model Gulfstream 200 airplanes, certificated in any category, serial

Subject

    (d) Instruments.

Reason

    (e) The mandatory continued airworthiness information (MCAI) 
states:
    Avionics and electrical wire harnesses are routed behind the
