14 CFR Part 39

[Docket No. FAA-2013-0093; Directorate Identifier 2011-NM-109-AD; 
Amendment 39-17515; AD 2013-14-10]
RIN 2120-AA64


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

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

ACTION: Final rule.

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

SUMMARY: We are superseding airworthiness directive (AD) 2010-11-02 for 
all Gulfstream Aerospace LP (Type Certificate Previously Held by Israel 
Aircraft Industries, Ltd.) Model Gulfstream 100 airplanes, and Model 
Astra SPX and 1125 Westwind Astra airplanes. AD 2010-11-02 required 
amending the airplane flight manuals (AFMs) to include additional 
procedures for verifying complete closure and locking of the main entry 
door (MED). AD 2010-11-02 also required modifying the warning and 
caution lights panel (WACLP), changing the WACLP and MED wiring, 
changing the wiring harness connecting the MED to the WACLP, and 
revising the log of modification of the AFM if necessary. This new AD 
revises the compliance time and removes an airplane from the 
applicability. This AD was prompted by a report of a MED opening in 
flight on an unmodified airplane. We are issuing this AD to prevent 
incomplete closure of the MED, which may result in the door opening in 
flight and possible separation of the door, causing damage to the 
airplane structure and left engine by flying debris and objects.

DATES: This AD becomes effective September 10, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 
10, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of June 
25, 2010 (75 FR 28485, May 21, 2010).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
The NPRM was published in the Federal Register on February 26, 2013 (78 
FR 12995), and proposed to supersede AD 2010-11-02, Amendment 39-16307 
(75 FR 28485, May 21, 2010), which superseded AD 2007-03-05, Amendment 
39-14916 (72 FR 4414, January 31, 2007). The NPRM proposed to correct 
an unsafe condition for the specified products. The Civil Aviation 
Authority of Israel (CAAI), which is the aviation authority for Israel, 
has issued Israeli Airworthiness Directive 31-06-11-05R1, dated May 18, 
2011 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    To increase pilots' awareness to the possibility of incomplete 
closure of the Main Entry Door (MED) by the following means:
    1. Splitting the common caution light CABIN DOOR signaling both 
MED Improper Closure and MED Inflatable Seal Failure into two 
separate lights: CABIN DOOR and CABIN DOOR SEAL.
    2. Converting the separated CABIN DOOR Caution light into a 
Warning light by changing its color to red.
    NOTE: Airplane Flight Manuals (AFM'S) refer to these changes as 
MOD G1-20052.
    Incomplete closure of the MED may be followed by in-flight 
opening and possible separation of the door. As a result, the MED, 
the adjacent fuselage structure and other parts of the aircraft may 
be damaged due to opening forces and landing impact.
    Damage to the aircraft structure and to the left engine by 
flying debris and objects may also occur.
* * * * *

    This AD retains the actions required by AD 2010-11-02, Amendment 
39-16307 (75 FR 28485, May 21, 2010). This AD limits the existing 
compliance time. This AD also removes the airplane having serial number 
(S/N) 158 from the applicability because the modification was done in 
production. You may obtain further information by examining the MCAI in 
the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 12995, February 26, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 12995, February 26, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 12995, February 26, 2013).

Costs of Compliance

    The new requirements of this AD add no additional economic burden. 
The current costs for this AD are repeated for the convenience of 
affected operators, as follows:
    We estimate that this AD will affect about 160 products of U.S. 
registry.
    The actions that were required by AD 2010-11-02, Amendment 39-16307 
(75 FR 28485, May 21, 2010), and retained in this AD take about 60 
work-hours per product, at an average labor rate of $85 per work-hour. 
Required parts cost about $600 per product. Based on these figures, the 
estimated cost of the actions required by this AD is $5,700 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 AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on

[[Page 47547]]

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 the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the

the following new AD:

2013-14-10 Gulfstream Aerospace LP (Type Certificate Previously Held 
by Israel Aircraft Industries, Ltd.): Amendment 39-17515. Docket No. 
FAA-2013-0093; Directorate Identifier 2011-NM-109-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective September 
10, 2013.
