We propose to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation (Gulfstream) Models G-IV and GIV-X airplanes. This proposed AD was prompted by reports of disbonding and surface cracking of the composite aft pressure bulkhead. This proposed AD would require inspections of the forward and aft surfaces of the pressure bulkhead composite panels for damage and repair of any damage found. We are proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Gulfstream Aerospace Corporation 
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 Corporation (Gulfstream) Models G-IV and 
GIV-X airplanes. This proposed AD was prompted by reports of disbonding 
and surface cracking of the composite aft pressure bulkhead. This 
proposed AD would require inspections of the forward and aft surfaces 
of the pressure bulkhead composite panels for damage and repair of any 
damage found. We are proposing this AD to address the unsafe condition 
on these products.

Discussion

    We received reports of disbonding and accompanying surface cracking 
of the composite aft pressure bulkhead on Gulfstream Model G-IV 
airplanes. Gulfstream Model GIV-X airplanes have the same type design. 
During scheduled maintenance, areas with disbonding and accompanying 
surface cracks were found. Operational pressure loads by-passing the 
disbonded facesheet caused wrinkling or compression failure and led to 
the surface cracking. This condition, if not addressed, could result in 
structural failure of the bulkhead and loss of cabin pressure.
    Airplanes maintained under Gulfstream's Maintenance Steering Group 
(MSG-3) maintenance program do not have a scheduled tap test inspection 
of the aft pressure bulkhead. Model G-IV airplanes with a serial number 
(S/N) 1400 through 1535, and Model GIV-X airplanes with a S/N 4001 
through 4004 adopted the MSG-3 maintenance program in production. 
Airplanes produced earlier may change to the MSG-3 program by following 
the instructions in Aircraft Service Change (ASC) No. 416A, dated 
September 29, 2000.

Related Service Information Under 1 CFR Part 51

    We reviewed Gulfstream G300 Customer Bulletin Number 243; 
Gulfstream G350 Customer Bulletin Number 198; Gulfstream G400 Customer 
Bulletin Number 243; Gulfstream G450 Customer Bulletin Number 198; and 
Gulfstream IV Customer Bulletin Number 243; all dated January 25, 2018. 
For the applicable airplanes, the service information describes 
procedures for inspecting the composite panels of the forward and aft 
pressure bulkhead for damage and repairing any damage found. 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.

Other Related Service Information

    We also reviewed ASC No. 416A, dated September 29, 2000, which 
contains instructions for changing the maintenance program for Model G-
IV airplanes from the airplane's existing program to the MSG-3 
maintenance program.

[[Page 35569]]

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 709 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
              Action                      Labor cost             Parts cost           product        operators
----------------------------------------------------------------------------------------------------------------
Inspection........................  18 work-hours x $85    Not applicable.......          $1,530      $1,084,770
                                     per hour = $1,530.
----------------------------------------------------------------------------------------------------------------

    The extent of damage found during the proposed inspection may vary 
from airplane to airplane. We have no way of determining the number of 
airplanes that might need repairs or the cost of such repairs for each 
airplane.

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 small airplanes, gliders, 
balloons, airships, domestic business jet transport airplanes, and 
associated appliances to the Director of the Policy and Innovation 
Division.

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.
