Airworthiness Directives; 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

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

ACTION: Final rule.

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

SUMMARY: We are superseding an existing 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:
* * * * *

    Incomplete closure of the MED [main entry door] may be followed 
by in-flight opening of the door. As a result, the MED and the 
adjacent fuselage structure may be damaged during opening and 
landing impact. Damage to the left engine by flying debris and 
objects may also occur.

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective June 25, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 25, 
2010.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC.

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. 
That NPRM was published in the Federal Register on February 8, 2010 (75 
FR 6157), and proposed to supersede AD 2007-03-05, Amendment 39-14916 
(72 FR 4414, January 31, 2007). That NPRM proposed 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: Aircraft Flight Manuals (AFM'S) refer to these changes as 
MOD G1-20052.
    Incomplete closure of the MED may be followed by in-flight 
opening of the door. As a result, the MED and the adjacent fuselage 
structure may be damaged during opening and landing impact. Damage 
to the left engine by flying debris and objects may also occur.

Required actions include 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 ensuring the Log of Modification 
of the AFM includes reference to MOD G1-20052. 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 or on the determination of 
the cost to the public.

Explanation of Change to Applicability

    We have revised the applicability of the existing AD to identify 
model designations as published in the most recent type certificate 
data sheet for the affected models.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously. We determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

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 required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a Note within the AD.

Explanation of Change to Costs of Compliance

    Since issuance of the NPRM, we have increased the labor rate used 
in the Costs of Compliance from $80 per work-hour to $85 per work-hour. 
The Costs of Compliance information, below, reflects

[[Page 28486]]

this increase in the specified hourly labor rate.

Costs of Compliance

    Based on the service information, we estimate that this AD will 
affect about 120 products of U.S. registry.
    The actions that are required by AD 2007-03-05 and retained in this 
AD take about 1 work-hour per product, at an average labor rate of $85 
per work hour. Based on these figures, the estimated cost of the 
currently required actions is $85 per product.
    We estimate that it will take about 60 additional work-hours per 
product to comply with the new basic requirements of this AD. Required 
parts will cost about $600 per product. The average labor rate is $85 
per work-hour. Where the service information lists required parts costs 
that are covered under warranty, we have assumed that there will be no 
charge for these costs. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $684,000, or $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 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.

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 the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

2. The FAA amends Sec.  39.13 by removing Amendment 39-14916 (72 FR 
4414, January 31, 2007) and adding the following new AD:

2010-11-02 Gulfstream Aerospace LP (Type Certificate Previously Held 
by Israel Aircraft Industries, Ltd.): Amendment 39-16307. Docket No. 
FAA-2010-0034; Directorate Identifier 2009-NM-120-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective June 25, 
2010.

Affected ADs

    (b) This AD supersedes AD 2007-03-05, Amendment 39-14916.

Applicability

    (c) This AD applies to 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; certificated in any category; all serial numbers.

Subject

    (d) Air Transport Association (ATA) of America Code 31: 
Instruments.

Reason

    (e) The mandatory continuing airworthiness information (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: Aircraft Flight Manuals (AFMs) refer to these changes as 
MOD G1-20052.

    Incomplete closure of the MED may be followed by in-flight 
opening of the door. As a result, the MED and the adjacent fuselage 
structure may be damaged during opening and landing impact. Damage 
to the left engine by flying debris and objects may also occur.

Required actions include 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 ensuring the Log 
of Modification of the AFM includes reference to MOD G1-20052.

Restatement of Requirements of AD 2007-03-05, With No Changes

    (f) Unless already done, do the following actions. Within 10 
days after February 15, 2007 (the effective date of AD 2007-03-05), 
amend Section IV, Normal Procedures, of the following Gulfstream 
airplane flight manuals (AFMs): Model 1125 Astra, 25W-1001-1; Model 
Astra SPX, SPX-1001-1; and Model G100, G100-1001-1; as applicable; 
to include the following statement. Insertion of copies of this AD 
at the appropriate places of the AFMs is acceptable.
    ``1. BEFORE ENGINE START:
    (PRE and POST Mod 20052/Gulfstream Service Bulletin 100-31-284):
    CABIN DOOR--CLOSED (Physically verify door latch handle pin is 
fully engaged in the handle lock)
    2. BEFORE TAXIING:
    Change the CABIN DOOR procedure as follows (POST Mod 20052/
Gulfstream Service Bulletin 100-31-284):
    Check CABIN DOOR light--OUT
    3. BEFORE TAKE-OFF:
    Insert between the POSITION lights switch and the THRUST LEVERS 
procedures:
    (PRE Mod 20052/Gulfstream Service Bulletin 100-31-284):
    Check CABIN DOOR light--OUT (50% N1 may be required)
    (POST Mod 20052/Gulfstream Service Bulletin 100-31-284):
    Check CABIN DOOR light--OUT

FAA AD Differences

    Note 3:  This AD differs from the MCAI and/or service 
information as follows: Paragraph (g)(5) of this AD mandates a 
terminating action. However, Israeli Airworthiness Directive 31-06-
11-05, dated May 27, 2009, does not explicitly mandate a terminating 
action. This difference has been coordinated with the Civil Aviation 
Authority of Israel.

Other FAA AD Provisions

    (h) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager,
