Airworthiness Directives; Gulfstream Aerospace Corporation 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-05-
12, which applied to all Gulfstream Aerospace Corporation Model GVII-
G500 and GVII-G600 airplanes. AD 2020-05-12 required revising the 
existing airplane flight manual (AFM) to incorporate revised 
limitations and procedures. This AD was prompted by reports of two 
landing incidents in which the alpha limiter engaged in the landing 
flare in unstable air, resulting in high rate of descent landings and 
damage to the airplanes. This AD retains certain requirements, and also 
adds and replaces certain AFM sections with more restrictive 
limitations and procedures. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective May 9, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 13, 
2020 (85 FR 14562, March 13, 2020).
    The FAA must receive comments on this AD by June 23, 2022.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued AD 2020-05-12, Amendment 39-19860 (85 FR 14562, 
March 13, 2020) (AD 2020-05-12), for all Gulfstream Aerospace 
Corporation Model GVII-G500 and GVII-G600 airplanes. AD 2020-05-12 
required revising the existing AFM to limit the maximum crosswind 
component for landing and increase the normal approach speeds, based on 
steady-state winds and wind gusts. AD 2020-05-12 was prompted by a 
report of a landing incident, which occurred on February 6, 2020, where 
the alpha (angle of attack) limiter engaged during the landing flare in 
unstable air, resulting in a high rate of descent landing and damage to 
the airplane. The FAA issued AD 2020-05-12 to address inappropriate 
alpha limiter engagement during the landing flare, which can limit 
pilot pitch authority during a critical phase of flight near the 
ground, and result in a high rate of descent landing with possible 
consequent loss of control of the airplane on landing.

Actions Since AD 2020-05-12 Was Issued

    After the FAA issued AD 2020-05-12, a second landing event occurred 
on April 4, 2022. As in the first event, the alpha limiter engaged 
during the landing flare in unstable air, resulting in a high rate of 
descent landing and damage to the airplane. In both events, the angle 
of attack (AOA) protection function (alpha limiter) of the flight 
control computer (FCC) engaged and overrode the pilot pitch control 
inputs which the flight control law erroneously predicted would exceed 
the stall AOA. This resulted in a high rate of descent landing on the 
runway. Additionally, the pilots in both events had full aft-stick 
input when the aircraft contacted the runway, and the full-up pitch 
control did not arrest the high rate of descent landing.
    The Model GVII-G500 and GVII-G600 alpha limiter function of the FCC 
is designed to prevent aerodynamic stalls and operates when airborne 
and operating in normal control law. The FCC uses many inputs including 
current AOA, rate of change of AOA, and pilot control stick inputs to 
determine alpha limiter activation. If the FCC predicts that critical 
AOA values will be exceeded, the FCC will activate the alpha limiting 
function. The FCC may activate the alpha limiting function when the AOA 
is not close to stall. Depending on the rate of AOA increase and pilot 
stick input, the alpha limiter may command nose down elevator to 
prevent a stall. It is clear from an analysis of both events that 
unintended alpha limiter engagement is primarily caused by rapid, 
large, and oscillating pilot control inputs near approach reference 
speeds, induced by unstable atmospheric conditions and gusty winds.
    The aircraft level hazard is that inappropriate alpha limiter 
engagement during the landing flare, which can limit the pilot's 
ability to control pitch during a critical phase of flight near the 
ground, can result in a high rate of descent landing with possible 
consequent loss of control of the airplane on landing. It has been 
determined that the operating limitations mandated by AD 2020-05-12 are 
not adequate to prevent another occurrence. For these reasons, the AFM 
wind and gust operating limitations have been further restricted in 
this AD.

Pilot Adherence to AFM Revisions To Mitigate the Unsafe Condition of 
Unintended Alpha Limiter Engagement

    These more restrictive operating limitations do not relieve a pilot 
from their other regulatory obligations, including verifying 
destination wind forecasts prior to departure, monitoring winds en 
route, verifying that the approach briefing includes a cockpit brief of 
winds and weather, and confirming that the winds are still within 
acceptable limits just prior to landing. Pilots are responsible for 
becoming familiar with this information when performing preflight 
actions under 14 CFR part 91.103, 91.151, and 91.167. Furthermore, 
these limitations can only be exceeded when the pilot is exercising 
their authority under 14 CFR part 91.3.

FAA's Determination

    The FAA is issuing this AD because the agency has determined the 
unsafe condition described previously is likely to exist or develop in 
other products of the same type design.

Interim Action

    The FAA considers this AD to be an interim action. The manufacturer 
is developing a modification that will address the unsafe condition 
identified in this AD. Once this modification is developed, approved, 
and available, the FAA might consider additional rulemaking.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies forgoing notice and comment prior to adoption of this rule 
because inappropriate alpha limiter engagement during the landing flare 
can limit pilot pitch authority during a critical phase of flight near 
the ground and could result in a high rate of descent landing with 
possible consequent loss of control of the airplane. Given the 
significance of the risk presented by this unsafe condition, it must be 
immediately addressed. Accordingly, notice and opportunity for prior 
public comment are impracticable and contrary to the public interest 
pursuant to 5 U.S.C. 553(b)(3)(B).
    In addition, the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days, 
for the same reasons the FAA found good cause to forgo notice and 
comment.

Comments Invited

    The FAA invites you to send any written data, views, or arguments 
about this final rule. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2022-0511 and Project Identifier 
AD-2022-00397-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the final rule, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this final rule because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this final rule.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this AD. Submissions containing CBI should be sent to Sanford 
Proveaux, Aerospace Engineer, Certificate Management and Safety 
Oversight Section, FAA, Atlanta ACO Branch, 1701 Columbia Avenue, 
College Park, GA 30337; phone: 404-474-5566; email: 
[email protected]. Any commentary that the FAA receives that is 
not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because the FAA has determined 
that it has good cause to adopt this rule without notice and comment, 
RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 120 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs

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.
    The FAA is 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.

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, and
    (2) Will not affect intrastate aviation in Alaska.
