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 G150 airplanes. This
proposed AD was prompted by reports of corrosion in the solder joints
of the upper and lower front relay box connectors to the printed
circuit board. This proposed AD would require replacement of the
existing relay boxes with modified boxes. We are proposing this AD to
address the unsafe condition on these products.
DATES: We must receive comments on this proposed AD by January 25,
2019.
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-24-2018-09-7, dated October 1, 2018 (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 existing Upper and Lower Front Relay Box might be prone to
corrosion in the relay box connector's solder joint to the printed
circuit board. As a result various CAS [crew alerting system]
messages such as slats unbalance and auto slats fail, Mach trim
fail, etc. . . . might be reported [and could interfere with
continued safe operation of the airplane]. To prevent this condition
replacement of existing relay boxes with modified boxes featuring an
added acrylic conformal coating should be performed.
Five occurrences on G150 model in last 3 years had been
reported.
[[Page 63597]]
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-2018-
1006.
Related Service Information Under 1 CFR Part 51
Gulfstream has issued Service Bulletin 150-24-193, dated March 30,
2018. This service information describes procedures for removing and
replacing the upper and lower front relay boxes.
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
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 the relevant information and determined the unsafe
condition described previously is likely to exist or develop on other
products of the same type design.
Proposed Requirements of This NPRM
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 81 airplanes of U.S.
registry. We estimate the following costs to comply with this proposed
AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
220 work-hours x $85 per hour = $18,700...................... $20,083 $38,783 $3,141,423
----------------------------------------------------------------------------------------------------------------
According to the manufacturer, some or all of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected individuals. We do not control warranty coverage for
affected individuals. As a result, we have included all known costs in
our cost estimate.
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 proposed 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 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.
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
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-2018-1006; Product
Identifier 2018-NM-142-AD.
(a) Comments Due Date
We must receive comments by January 25, 2019.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Gulfstream Aerospace LP (Type Certificate
previously held by Israel Aircraft Industries, Ltd.) Model
Gulfstream G150 airplanes, certificated in any category, serial
numbers 201 through 326 inclusive.
(d) Subject
Air Transport Association (ATA) of America Code 24, Electrical
power.
(e) Reason
This AD was prompted by reports of corrosion in the solder
joints of the upper and lower front relay box connectors to the
printed circuit board. We are issuing this AD to address corrosion
in the front relay box connector solder joints. If not addressed,
this condition could cause false crew alerting system (CAS)
messages, such as slats unbalance, auto slats fail, and Mach trim
fail, which could interfere with continued safe operation of the
airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
[[Page 63598]]
(g) Replacement
Within 36 months after the effective date of this AD, remove the
upper front relay box, Israel Aerospace Industries (IAI) part number
(P/N) 25G8130301-510/-512/-514/-516, and replace with IAI P/N
25G8130301-516, upgraded to MOD A, and remove the lower front relay
box, IAI P/N 25G8130300-512/-516/-518/-520, and replace with an
improved lower front relay box, IAI P/N 25G8130300-520, upgraded to
MOD A, in accordance with the Accomplishment Instructions of
Gulfstream Service Bulletin 150-24-193, dated March 30, 2018.
