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.

DATES: We must receive comments on this proposed AD by April 12, 2013.

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On May 7, 2010, we issued AD 2010-11-02, Amendment 39-16307 (75 FR 28485, May 21, 2010), which superseded AD 2007-03-05, Amendment 39-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:

  3. Is not a ``significant regulatory action'' under Executive Order 12866;

  4. Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);

  5. Will not affect intrastate aviation in Alaska; and

  6. 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, Incorporation by reference, 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

    0

  7. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

    Sec. 39.13 Amended

    0

  8. The FAA amends Sec. 39.13 by removing airworthiness directive (AD) 2010-11-02, Amendment 39-16307 (75 FR 28485, May 21, 2010), and adding the following new AD:

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

    (a) Comments Due Date

    We must receive comments by April 12, 2013.

    (b) Affected ADs

    This AD supersedes AD 2010-11-02, Amendment 39-16307 (75 FR 28485, May 21, 2010).
