AGENCY:
We are adopting a new
airworthiness directive (AD) for all
Airbus Model A318, A319, A320, and
A321 series airplanes. This emergency
AD was sent previously to all known
U.S. owners and operators of these
airplanes. This AD requires revising the
airplane flight manual to advise the
flightcrew of emergency procedures for
abnormal Alpha Protection (Alpha Prot).
This AD was prompted by a report of
Angle of Attack (AoA) probes jamming
on an in-service Airbus Model A321
airplane. Jamming of the two AoA
probes during climb is attributed to
water freezing under the AoA vane
slinger, and led to activation of the
Alpha Prot while the Mach number
increased, which resulted in an airplane
pitch down per design. We are issuing
this AD to ensure that the flightcrew has
procedures to counteract the pitch down
order due to abnormal activation of the
Alpha Prot. An abnormal Alpha Prot, if
not corrected, could result in loss of
control of the airplane.
DATES: This AD is effective February 6,
2015 to all persons except those persons
to whom it was made immediately
effective by Emergency AD 2014–25–51,
issued on December 10, 2014, which
contained the requirements of this
amendment.
We must receive comments on this
AD by March 9, 2015.

SUPPLEMENTARY INFORMATION:
Discussion
On December 10, 2014, we issued
Emergency AD 2014–25–51, which
requires revising the airplane flight
manual to advise the flightcrew of
emergency procedures for abnormal
Alpha Prot. This emergency AD was
sent previously to all known U.S.
owners and operators of these airplanes.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued Emergency
Airworthiness Directive 2014–0266–E,
dated December 9, 2014 (referred to
after this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
on all Model A318, A319, A320, and
A321 series airplanes. The MCAI states:
An occurrence was reported where an
Airbus A321 aeroplane encountered a
blockage of two Angle of Attack (AoA) probes
during climb, leading to activation of the
Alpha Protection (Alpha Prot) while the
Mach number increased. The flightcrew
PO 00000
Frm 00015
Fmt 4700
Sfmt 4700
3153
managed to regain full control and the flight
landed uneventfully.
When Alpha Prot is activated due to
blocked AoA probes, the flight control laws
order a continuous nose down pitch rate that,
in a worst case scenario, cannot be stopped
with backward sidestick inputs, even in the
full backward position. If the Mach number
increases during a nose down order, the AoA
value of the Alpha Prot will continue to
decrease. As a result, the flight control laws
will continue to order a nose down pitch
rate, even if the speed is above minimum
selectable speed, known as VLS.
This condition, if not corrected, could
result in loss of control of the aeroplane.
To address this unsafe condition, Airbus
* * * [has] developed a specific Aircraft
Flight Manual (AFM) procedure, which has
been published in AFM Temporary Revision
(TR) No. 502.
For the reasons described above, this AD
requires amendment of the applicable AFM
[to advise the flightcrew of emergency
procedures for abnormal Alpha Prot].
This is considered to be an interim action
and further [EASA] AD action may follow.
FAA’s Determination and AD
Requirements
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 issuing this
AD because we evaluated all pertinent
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD. The FAA has found that the risk to
the flying public justifies waiving notice
and comment prior to adoption of this
rule because an abnormal Alpha Prot, if
not corrected, could result in loss of
control of the airplane. Therefore, we
find that notice and opportunity for
prior public comment are impracticable
and 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
this AD. Send your comments to an

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.

America Code 34, Navigation.
(e) Unsafe Condition
This AD was prompted by a report of
Angle of Attack (AoA) probes jamming on an
in-service Airbus Model A321 airplane.
Jamming of the two AoA probes during climb
is attributed to water freezing under the AoA
vane slinger, and led to activation of the
Alpha Protection (Alpha Prot) while the
Mach number increased, which resulted in
an airplane pitch down per design. We are
issuing this AD to ensure the flightcrew has
procedures to counteract the pitch down
order due to abnormal activation of the
Alpha Prot. An abnormal Alpha Prot, if not
corrected, could result in loss of control of
the airplane.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
(g) Revision of Airplane Flight Manual
(AFM)
Within 2 days after the effective date of
this AD, revise the AFM to incorporate
procedures to address undue activation of
Alpha Prot by inserting the text specified in
figure 1 to paragraph (g) of this AD into the
Emergency Procedures section of the
applicable AFM, to advise the flightcrew of
emergency procedures for abnormal Alpha
Prot. This may be accomplished by inserting
a copy of this AD into the AFM. When a
statement identical to the text specified in
figure 1 to paragraph (g) of this AD is
included in the general revisions of the AFM,
the general revisions may be inserted in the
AFM, and the text specified in figure 1 to
paragraph (g) of this AD may be removed.

On December 10, 2014, we issued Emergency AD 2014-25-51, which
requires revising the airplane flight manual to advise the flightcrew
of emergency procedures for abnormal Alpha Prot. This emergency AD was
sent previously to all known U.S. owners and operators of these
airplanes.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued Emergency
Airworthiness Directive 2014-0266-E, dated December 9, 2014 (referred
to after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition on all Model A318, A319,
A320, and A321 series airplanes. The MCAI states:
An occurrence was reported where an Airbus A321 aeroplane
encountered a blockage of two Angle of Attack (AoA) probes during
climb, leading to activation of the Alpha Protection (Alpha Prot)
while the Mach number increased. The flightcrew managed to regain
full control and the flight landed uneventfully.
When Alpha Prot is activated due to blocked AoA probes, the
flight control laws order a continuous nose down pitch rate that, in
a worst case scenario, cannot be stopped with backward sidestick
inputs, even in the full backward position. If the Mach number
increases during a nose down order, the AoA value of the Alpha Prot
will continue to decrease. As a result, the flight control laws will
continue to order a nose down pitch rate, even if the speed is above
minimum selectable speed, known as VLS.
This condition, if not corrected, could result in loss of
control of the aeroplane.
To address this unsafe condition, Airbus * * * [has] developed a
specific Aircraft Flight Manual (AFM) procedure, which has been
published in AFM Temporary Revision (TR) No. 502.
For the reasons described above, this AD requires amendment of
the applicable AFM [to advise the flightcrew of emergency procedures

This is considered to be an interim action and further [EASA] AD
action may follow.
FAA's Determination and AD Requirements
This product has been approved by the aviation authority of another

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.
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.
List of Subjects in 14 CFR Part 39

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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):
2014-25-51 Airbus: Amendment 39-18067; Docket No. FAA-2014-0924;
Directorate Identifier 2014-NM-228-AD.
(a) Effective Date
This AD is effective February 6, 2015 to all persons except
those persons to whom it was made immediately effective by Emergency
AD 2014-25-51, issued on December 10, 2014, which contained the
requirements of this amendment.
(b) Affected ADs
None.
(c) Applicability
This AD applies to the Airbus airplanes, certificated in any
category, identified in paragraphs (c)(1), (c)(2), (c)(3), and
(c)(4) of this AD.
(1) All Model A318-111, -112, -121, and -122 airplanes.
(2) All Model A319-111, -112, -113, -114, -115, -131, -132, and
-133 airplanes.
(3) All Model A320-211, -212, -214, -231, -232, and -233
airplanes.
(4) All Model A321-111, -112, -131, -211, -212, -213, -231, and
-232 airplanes.
(d) Subject
Air Transport Association (ATA) of America Code 34, Navigation.
(e) Unsafe Condition
This AD was prompted by a report of Angle of Attack (AoA) probes
jamming on an in-service Airbus Model A321 airplane. Jamming of the
two AoA probes during climb is attributed to water freezing under
the AoA vane slinger, and led to activation of the Alpha Protection
(Alpha Prot) while the Mach number increased, which resulted in an
airplane pitch down per design. We are issuing this AD to ensure the
flightcrew has procedures to counteract the pitch down order due to
abnormal activation of the Alpha Prot. An abnormal Alpha Prot, if
not corrected, could result in loss of control of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Revision of Airplane Flight Manual (AFM)
Within 2 days after the effective date of this AD, revise the
AFM to incorporate procedures to address undue activation of Alpha
Prot by inserting the text specified in figure 1 to paragraph (g) of
this AD into the Emergency Procedures section of the applicable AFM,
to advise the flightcrew of emergency procedures for abnormal Alpha
Prot. This may be accomplished by inserting a copy of this AD into
the AFM. When a statement identical to the text specified in figure
1 to paragraph (g) of this AD is included in the general revisions
of the AFM, the general revisions may be inserted in the AFM, and
the text specified in figure 1 to paragraph (g) of this AD may be
removed.
[[Page 3155]]
Figure 1 to Paragraph (g) of This AD--AFM Procedure
------------------------------------------------------------------------
-------------------------------------------------------------------------
At any time, with a speed above VLS, if the aircraft goes to a
continuous nose down pitch rate that cannot be stopped with backward
sidestick inputs, immediately:
Keep on one ADR.
Turn off two ADRs.
If the Alpha Max strip (red) hides completely the Alpha Prot
strip (black and amber) in a stabilized wings-level flight path
(without an increase in load factor):
Keep on one ADR.
Turn off two ADRs.
In case of dispatch with one ADR inoperative, switch only one ADR to
OFF.
CAUTION RISK OF ERRONEOUS DISPLAY OF THE VSW STRIP (RED AND
BLACK)
Consider using the Flight Path Vector (FPV).
If the Alpha Prot strip (black and amber) rapidly moves by more
than 30 kt during flight maneuvers (with an increase in load factor),
with AP ON and speed brakes retracted:
Keep on one ADR.
Turn off two ADRs.
In case of dispatch with one ADR inoperative, switch only one ADR to
OFF.
CAUTION RISK OF ERRONEOUS DISPLAY OF THE VSW STRIP (RED AND BLACK)
Consider using the Flight Path Vector (FPV).
------------------------------------------------------------------------
(h) Special Flight Permits
Special flight permits, as described in Section 21.197 and
Section 21.199 of the Federal Aviation Regulations (14 CFR 21.197
and 21.199), are not allowed.
