14 CFR Part 39

[Docket No. FAA-2017-0692; Product Identifier 2017-NM-043-AD; Amendment 
39-19075; AD 2017-21-04]

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 adopting a new airworthiness directive (AD) for certain 
Gulfstream Aerospace LP Model Gulfstream G150 airplanes. This AD was 
prompted by a report indicating 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 AD requires accomplishing an 
updated rigging procedure for the adjustment of the MED microswitch. We 
are issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective November 27, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 27, 
2017.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Gulfstream 
Aerospace LP Model Gulfstream G150 airplanes. The NPRM published in the 
Federal Register on July 17, 2017 (82 FR 32656) (``the NPRM'').
    The Civil Aviation Authority of Israel (CAAI), which is the 
aviation authority for Israel, has issued Israeli Airworthiness 
Directive ISR-I-52-2017-03-28, 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 G150 airplanes. The MCAI states:

    [The purpose of the Israeli AD is] to improve the Main Entrance 
Door (MED) 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-2017-0692.

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.

[[Page 48916]]

Conclusion

    We reviewed the relevant 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 for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Gulfstream Aerospace LP has issued Gulfstream G150 Service Bulletin 
150-52-188, 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.

Costs of Compliance

    We estimate that this AD affects 65 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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 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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

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

2017-21-04 Gulfstream Aerospace LP (Type Certificate Previously Held 
by Israel Aircraft Industries, Ltd.): Amendment 39-19075; Docket No. 
FAA-2017-0692; Product Identifier 2017-NM-043-AD.

issuing this AD to prevent the MED from opening during flight, which 
could lead to structural damage and loss of control of the airplane.
