SUMMARY: Examining the AD Docket You may examine the AD docket on the internet at https:// 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 December 11, 2018 (83 FR 63596). The NPRM was prompted by reports of corrosion in the solder joints of the upper and lower front relay box connectors to the printed circuit board. The NPRM proposed to require replacement of the existing relay boxes with modified boxes. 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. 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. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 1006. Comments We gave the public the opportunity to participate in developing this final rule. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this final rule 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 addressing 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 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. Costs of Compliance We estimate that this AD affects 81 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 220 work-hours × $85 per hour = $18,700 ................................................................................. $20,083 $38,783 $3,141,423 VerDate Sep<11>2014 16:21 Mar 01, 2019 Jkt 247001 PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 E:\FR\FM\04MRR1.SGM 04MRR1 Federal Register / Vol. 84, No. 42 / Monday, March 4, 2019 / Rules and Regulations According to the manufacturer, some or all of the costs of this 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.

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 December 11, 2018 (83 FR 63596). The NPRM was 
prompted by reports of corrosion in the solder joints of the upper and 
lower front relay box connectors to the printed circuit board. The NPRM 
proposed to require replacement of the existing relay boxes with 
modified boxes.
    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.
    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.

    You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2018-
1006.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this final rule 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 addressing 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 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.

Costs of Compliance

    We estimate that this AD affects 81 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

[[Page 7273]]

    According to the manufacturer, some or all of the costs of this 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 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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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:

fail, which could interfere with continued safe operation of the 
airplane.
