RIN 2120-AA64


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 adopt a new airworthiness directive (AD) for 
certain Gulfstream Aerospace LP Model Gulfstream 100, Astra SPX, and 
1125 Westwind Astra airplanes. This proposed AD was prompted by a 
report that the main entrance door (MED) opened during flight, and by 
the determination that the ``CABIN DOOR UNLOCK'' crew alerting system 
(CAS) message may extinguish before the handle latch pin is fully 
engaged. This proposed AD would require accomplishing an updated 
rigging procedure for the adjustment of the MED microswitch. We are 
proposing this AD to address the unsafe condition on these products.

DATES: We must receive comments on this NPRM by August 31, 2017.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The Civil Aviation Authority of Israel (CAAI), which is the 
aviation authority for Israel, has issued Israeli Airworthiness 
Directive ISR-I-52-2017-03-29, dated January 3, 2017 (referred to after 
this as the Mandatory Continuing Airworthiness Information, or ``the 
MCAI''), to correct an unsafe condition for certain Gulfstream 
Aerospace LP Model Gulfstream 100, Astra SPX, and 1125 Westwind Astra 
airplanes. The MCAI states:

    [The purpose of the Israeli AD is] to improve the Main Entrance 
Door (MED)

[[Page 32655]]

microswitch adjustment procedure so that the locking indication will 
be extinguished when the door handle is locked.

    The required actions include accomplishing an updated rigging 
procedure for the adjustment of the MED microswitch. The unsafe 
condition is the in-flight opening of the MED, which could lead to 
structural damage and loss of control of the airplane. You may examine 
the MCAI in the AD docket on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2017-0693.

Related Service Information Under 1 CFR Part 51

    Gulfstream Aerospace LP has issued G100 Service Bulletin 100-52-
312, dated January 15, 2016. The service information describes an 
updated rigging procedure for the adjustment of the MED microswitch. 
This service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 110 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

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

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.

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
1. 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
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Gulfstream Aerospace LP (Type Certificate Previously Held by Israel 
Aircraft Industries, Ltd.): Docket No. FAA-2017-0693; Directorate 
Identifier 2017-NM-044-AD.

(a) Comments Due Date

    We must receive comments by August 31, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Gulfstream Aerospace LP Model Gulfstream 100, 
Astra SPX, and 1125 Westwind Astra airplanes, certificated in any 
category, serial numbers 004, and 011 through 158 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 52, Doors.

(e) Reason

    This AD was prompted by a report that the main entrance door 
(MED) opened during flight, and by the determination that the 
``CABIN DOOR UNLOCK'' crew alerting system (CAS) message may 
extinguish before the handle latch pin is fully engaged. We are 
issuing this AD to prevent the MED from opening during flight, which 
could lead to structural damage and loss of control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Rigging Procedure

    Within 12 months after the effective date of this AD: Do an 
updated rigging procedure for the adjustment of the MED microswitch, 
in accordance with the Accomplishment Instructions of Gulfstream 
G100 Service Bulletin 100-52-312, dated January 15, 2016.

(h) Other FAA AD Provisions

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

Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
local flight standards district office/certificate holding district 
office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain corrective actions from a manufacturer, the action must be 
accomplished using a method approved by the Manager, International
