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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive 
(AD) that applies to all Gulfstream Aerospace

[[Page 12996]]

LP (Type Certificate Previously Held by Israel Aircraft Industries, 
Ltd.) Model Gulfstream 100 airplanes, and Model Astra SPX and 1125 
Westwind Astra airplanes. The existing AD currently requires amending 
the airplane flight manuals (AFMs) to include additional procedures for 
verifying complete closure and locking of the main entry door (MED). 
The existing AD also currently requires 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. Since we 
issued that AD, we have determined that the compliance time must be 
revised to ensure the unsafe condition is addressed on low utilization 
airplanes. We have also removed one airplane from the applicability. We 
are proposing 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.

Discussion

    On May 7, 2010, we issued 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28485, May 21, 2010), which superseded AD 2007-03-05, Amendment 39-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). That AD required actions intended 
to address an unsafe condition on the products listed above.
    Since we issued AD 2010-11-02, Amendment 39-16307 (75 FR 28485, May 
21, 2010), we have determined that the compliance time must be revised 
to ensure the unsafe condition is addressed on low utilization 
airplanes. We have also removed one airplane from the applicability. 
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 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 proposed AD retains the actions required by AD 2010-11-02. This 
proposed AD limits the existing compliance time by specifying ``no 
later than 6 months after the effective date of this AD.'' This 
proposed 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.

Relevant Service Information

    Gulfstream Aerospace LP (Type Certificate Previously Held by Israel 
Aircraft Industries, Ltd.) has issued Service Bulletin 100-31-284, 
Revision 1, dated May 27, 2011. 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 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 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.

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:
    Based on the service information, we estimate that this proposed AD 
would

[[Page 12997]]

affect about 160 products of U.S. registry.
    The actions that are required by AD 2010-11-02, Amendment 39-16307 
(75 FR 28485, May 21, 2010) and retained in this proposed 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 currently required actions 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 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);
    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 proposed AD and placed it in the AD docket.
