SUPPLEMENTARY INFORMATION: Discussion On November 7, 2018, we issued Emergency AD 2018–23–51, which requires revising certificate limitations and operating procedures of the AFM to provide the flight crew with runaway horizontal stabilizer trim procedures to follow under certain conditions. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This action was prompted by analysis performed by the manufacturer showing that if an erroneously high single AOA sensor input is received by the flight control system, there is a potential for repeated PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 62697 nose-down trim commands of the horizontal stabilizer. This condition, if not addressed, could cause the flight crew to have difficulty controlling the airplane, and lead to excessive nosedown attitude, significant altitude loss, and possible impact with terrain. FAA’s Determination We are issuing 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. AD Requirements This AD requires revising certificate limitations and operating procedures of the AFM to provide the flight crew with runaway horizontal stabilizer trim procedures to follow under certain conditions. Interim Action We consider this AD interim action. If final action is later identified, we might consider further rulemaking then. FAA’s Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of Emergency AD 2018–23–51, issued on November 7, 2018, to all known U.S. owners and operators of these airplanes. The FAA found that the risk to the flying public justified waiving notice and comment prior to adoption of this rule because an erroneously high single AOA sensor input received by the flight control system can result in a potential for repeated nose-down trim commands of the horizontal stabilizer, which could cause the flight crew to have difficulty controlling the airplane, and lead to excessive nose-down attitude, significant altitude loss, and possible impact with terrain. These conditions still exist and the AD is hereby published in the Federal Register as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13) to make it effective to all persons. Therefore, we find good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reason(s) stated above, we find that good cause exists for making this amendment effective in less than 30 days.

SUMMARY: We are adopting a new airworthiness directive (AD) for all The 
Boeing Company Model 737-8 and -9 airplanes. This emergency AD was sent 
previously to all known U.S. owners and operators of these airplanes. 
This AD requires revising certificate limitations and operating 
procedures of the airplane flight manual (AFM) to provide the flight 
crew with runaway horizontal stabilizer trim procedures to follow under 
certain conditions. This AD was prompted by analysis performed by the 
manufacturer showing that if an erroneously high single angle of attack 
(AOA) sensor input is received by the flight control system, there is a 
potential for repeated nose-down trim commands of the horizontal 
stabilizer. We are issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective December 21, 2018 to all persons except 
those persons to whom it was made immediately effective by Emergency AD 
2018-23-51, issued on November 7, 2018, which contained the 
requirements of this amendment.
    We must receive comments on this AD by January 22, 2019.

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

SUPPLEMENTARY INFORMATION:

Discussion

    On November 7, 2018, we issued Emergency AD 2018-23-51, which 
requires revising certificate limitations and operating procedures of 
the AFM to provide the flight crew with runaway horizontal stabilizer 
trim procedures to follow under certain conditions. This emergency AD 
was sent previously to all known U.S. owners and operators of these 
airplanes. This action was prompted by analysis performed by the 
manufacturer showing that if an erroneously high single AOA sensor 
input is received by the flight control system, there is a potential 
for repeated nose-down trim commands of the horizontal stabilizer. This 
condition, if not addressed, could cause the flight crew to have 
difficulty controlling the airplane, and lead to excessive nose-down 
attitude, significant altitude loss, and possible impact with terrain.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires revising certificate limitations and operating 
procedures of the AFM to provide the flight crew with runaway 
horizontal stabilizer trim procedures to follow under certain 
conditions.

Interim Action

    We consider this AD interim action. If final action is later 
identified, we might consider further rulemaking then.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
Emergency AD 2018-23-51, issued on November 7, 2018, to all known U.S. 
owners and operators of these airplanes. The FAA found that the risk to 
the flying public justified waiving notice and comment prior to 
adoption of this rule because an erroneously high single AOA sensor 
input received by the flight control system can result in a potential 
for repeated nose-down trim commands of the horizontal stabilizer, 
which could cause the flight crew to have difficulty controlling the 
airplane, and lead to excessive nose-down attitude, significant 
altitude loss, and possible impact with terrain. These conditions still 
exist and the AD is hereby published in the Federal Register as an 
amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 
39.13) to make it effective to all persons. Therefore, we find good 
cause that notice and opportunity for prior public comment are 
impracticable. In addition, for the reason(s) stated above, we find 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about

[[Page 62698]]

this final rule. Send your comments to an address listed under the 
ADDRESSES section. Include the docket number FAA-2018-0960 and Product 
Identifier 2018-NM-151-AD at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this final rule. We will consider 
all comments received by the closing date and may amend this final rule 
because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this final rule.

Costs of Compliance

    We estimate that this AD affects 45 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 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:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.
