SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from mandatory continuing
airworthiness information (MCAI)
issued by an airworthiness authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as an incomplete discharge of
the extinguishing agent in the fire zone,
which could lead, in the worst case, in
combination with an engine fire, to a
temporary uncontrolled engine fire. We
are issuing this AD to require actions to
correct the unsafe condition on these
products.
DATES: This AD becomes effective April
19, 2007.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of April 19, 2007.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA is implementing a new
process for streamlining the issuance of
ADs related to MCAI. This streamlined
process will allow us to adopt MCAI
safety requirements in a more efficient
manner and will reduce safety risks to
the public. This process continues to
allow all FAA AD issuance processes to
meet legal, economic, Administrative
Procedure Act, and Federal Register
VerDate Aug<31>2005

Jkt 211001
requirements. We also continue to meet
our technical decision-making
responsibilities to identify and correct
unsafe conditions on U.S.-certificated
products.
This AD references the MCAI and
related service information that we
considered in forming the engineering
basis to correct the unsafe condition.
The AD contains text copied from the
MCAI and for this reason might not
follow our plain language principles.
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on January 12, 2007 (72 FR
1470). That NPRM proposed to require
a one-time detailed visual inspection for
the presence of the retaining-ring on the
discharge head assembly of the engine
fire extinguishing system, and repair if
necessary. The MCAI states that one
Model A330 operator discovered that
the line connection to the discharge
head could not be properly secured
during engine fire bottle replacement,
due to a missing retaining-ring.
Inspections revealed that all four
discharge-heads line connectors, two
per engine, were missing the retainingring. It was confirmed later that it was
a quality issue.
The function of the retaining-ring is to
secure a tight connection between the
fire-extinguishing line and the discharge
head. In absence of the retaining-ring, in
case of activation of the fire
extinguishing system, the pressure
exerted by the agent on the pipe could
compromise the tightness of the
connection, leading to an incomplete
discharge of the extinguishing agent in
the fire zone.
This situation if not corrected could
lead, in the worst case, in combination
with an engine fire, to a temporary
uncontrolled engine fire which
constitutes an unsafe condition.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comment received. The
commenter, Jonathan Frederick,
supports the NPRM.
Conclusion
We reviewed the available data,
including the comments received, and
determined that air safety and the
public interest require adopting the AD
as proposed.
Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
PO 00000
Frm 00041
Fmt 4700

general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable in a U.S.
court of law. In making these changes,
we do not intend to differ substantively
from the information provided in the
MCAI and related service information.
We might also have required different
actions in this AD from those in the
MCAI in order to follow our FAA
policies. Any such differences are
described in a separate paragraph of the
AD. These requirements, if any, take
precedence over the actions copied from
the MCAI.
Costs of Compliance
We estimate that this AD will affect
27 products of U.S. registry. We also
estimate that it will take about 4 workhours per product to comply with this
AD. The average labor rate is $80 per
work-hour. Required parts will cost
about $0 per product. Where the service
information lists required parts costs
that are covered under warranty, we
have assumed that there will be no
charge for these parts. As we do not
control warranty coverage for affected
parties, some parties may incur costs
higher than estimated here. Based on
these figures, we estimate the cost of
this AD to the U.S. operators to be
$8,640, or $320 per product.
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.
Regulatory Findings
We determined that 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,

Federal Register / Vol. 72, No. 50 / Thursday, March 15, 2007 / Rules and Regulations
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); and
(3) 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD Docket.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://dms.dot.gov; or in

Reason
(d) The mandatory continuing
airworthiness information (MCAI) states that
one Model A330 operator discovered that the
line connection to the discharge head could
not be properly secured during engine fire
bottle replacement, due to a missing
retaining-ring. Inspections revealed that all
four discharge-heads line connectors, two per
engine, were missing the retaining-ring. It
was confirmed later that it was a quality
issue. The function of the retaining-ring is to
secure a tight connection between the fireextinguishing line and the discharge head. In
absence of the retaining-ring, in case of
activation of the fire extinguishing system,
the pressure exerted by the agent on the pipe
could compromise the tightness of the
connection, leading to an incomplete
discharge of the extinguishing agent in the
fire zone. This situation if not corrected
could lead, in the worst case, in combination
with an engine fire, to a temporary
uncontrolled engine fire which constitutes an
unsafe condition. The MCAI requires a onetime detailed visual inspection for the
presence of the retaining-ring on the
discharge head assembly of engine fire
extinguishing system, and repair if necessary.
Actions and Compliance
(e) Unless already done, do the following
actions. Within 900 flight hours from the
effective date of this AD: On both engine
pylons (left hand and right hand), for all four
engine fire extinguisher bottles, two per
engine pylon, perform a one-time detailed
visual inspection for the presence of the
retaining ring on the discharge head of the
bottles and apply all applicable corrective
actions, in accordance with instructions
defined in Airbus Service Bulletin A330–
26A3037, dated July 26, 2006. Do all
applicable corrective actions before further
flight. Aircraft on which the four engine fire
extinguishing bottles, 2 per engine pylon,
have been removed and re-installed at the
opportunity of hydrostatic test of engine fire
extinguishing as per Airbus A330
Maintenance Review Board Report (MRBR)
task 26.21.00/04, are not concerned by this
AD.

The FAA is implementing a new process for streamlining the issuance
of ADs related to MCAI. This streamlined process will allow us to adopt
MCAI safety requirements in a more efficient manner and will reduce
