Federal Register / Vol. 75, No. 85 / Tuesday, May 4, 2010 / Rules and Regulations
Authority for This Rulemaking
§ 39.13
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
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), 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.
You can find our regulatory
evaluation and the estimated costs of
compliance in the AD Docket.
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

2. The FAA amends § 39.13 by adding
the following new AD:
2010–09–12 McDonnell Douglas
Corporation: Amendment 39–16277.
Docket No. FAA–2010–0032; Directorate
Identifier 2009–NM–213–AD.
Effective Date
(a) This airworthiness directive (AD) is
effective June 8, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to McDonnell Douglas
Corporation Model DC–10–10, DC–10–10F,

Federal Register / Vol. 75, No. 85 / Tuesday, May 4, 2010 / Rules and Regulations
airworthiness directive (AD) that was
published in the Federal Register on
March 11, 2010. The error resulted in an
imprecise compliance time in a table.
This AD applies to certain Airbus Model
A300 B2–1C, B2–203, B2K–3C, B4–103,
B4–203, B4–2C airplanes; Model A310
series airplanes; and Model A300 B4–
601, B4–603, B4–605R, B4–620, B4–622,
and B4–622R airplanes. This AD
requires repetitive inspections to detect
cracks of the pylon side panels (upper
section) at rib 8; and corrective actions
if necessary.
DATES: This correction is effective May
4, 2010. The effective date of AD 2010–
06–04 remains April 15, 2010.

SUPPLEMENTARY INFORMATION: On March
4, 2010, the FAA issued AD 2010–06–
04, Amendment 39–16228 (75 FR
11428, March 11, 2010), for certain
Airbus Model A300 B2–1C, B2–203,
B2K–3C, B4–103, B4–203, B4–2C
airplanes; Model A310 series airplanes;
and Model A300 B4–601, B4–603, B4–
605R, B4–620, B4–622, and B4–622R
airplanes. The AD requires repetitive
23573
inspections to detect cracks of the pylon
side panels (upper section) at rib 8; and
corrective actions if necessary.
As published, Table 1 of this AD
contained a typographical error in the
second row in the second column. The
compliance time of ‘‘>17,500 total
flight 1 ’’ has been corrected to read
’’>17,500 total flight cycles 1.’’ (The word
‘‘cycles’’ was omitted in the AD.)
No other part of the regulatory
information has been changed;
therefore, the final rule is not
republished in the Federal Register.
The effective date of this AD remains
April 15, 2010.

In the Federal Register of March 11,
2010, on page 11430, in the second row

Final rule.
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD) for
CFM International, S.A. CFM56–5B
series turbofan engines. That AD
requires reviewing exhaust gas
temperature (EGT) monitoring records
to determine EGT margin deterioration,
and for airplanes where both engines
have greater than 80 °centigrade (C) of
EGT margin deterioration, borescopeinspecting the high-pressure compressor
(HPC) of both engines. That AD also
requires removing from service any
engine that does not pass the borescope
inspection and, if both engines pass,
replacing one of the engines with an
engine that has 80 °C or less of EGT
margin deterioration. That AD also
requires continuous monitoring of EGT
margin deterioration on engines in
service to prevent two engines on an
airplane from having greater than 80 °C
of EGT margin deterioration. This AD:
• Reduces the number of engine
models affected;
• Continues to monitor EGT margin
deterioration;
• Lowers the EGT margin threshold
from 80 °C to 75 °C;
• Removes FADEC software version
5.B.Q and earlier versions from the
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
engine as mandatory terminating action
to the continuous EGT margin
deterioration monitoring, for certain
engine models;
• Removes the requirement to
borescope inspect; and
• Removes the requirement to replace
one of the engines with an engine that
has 80 °C or less deterioration of EGT
margin as a corrective action.
This AD results from a reduction of
the affected engine models listed in AD
2009–01–01 from 25 to 19, a reduction
in the engine EGT margin deterioration
threshold from 80 °C to 75 °C, the
introduction of terminating action to the
continuous EGT monitoring for certain
engines, and a change to the removal
plan for the remaining engines if the
EGT margin deterioration is greater than
75 °C. We are issuing this AD to prevent
HPC stalls, which could prevent
continued safe flight or landing.
DATES: This AD becomes effective June
8, 2010. The Director of the Federal
Register approved the incorporation by
reference of certain publications listed
in the regulations as of June 8, 2010.

SUMMARY: The FAA is correcting a typographical error in an existing
[[Page 23573]]
airworthiness directive (AD) that was published in the Federal Register
on March 11, 2010. The error resulted in an imprecise compliance time
in a table. This AD applies to certain Airbus Model A300 B2-1C, B2-203,

and Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, and B4-622R
airplanes. This AD requires repetitive inspections to detect cracks of

if necessary.
DATES: This correction is effective May 4, 2010. The effective date of
AD 2010-06-04 remains April 15, 2010.
ADDRESSES: You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Management Facility
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains this AD, the regulatory evaluation,
any comments received, and other information. The address for the
Docket Office (telephone 800-647-5527) is the Document Management
Facility, U.S. Department of Transportation, Docket Operations, M-30,

SUPPLEMENTARY INFORMATION: On March 4, 2010, the FAA issued AD 2010-06-
04, Amendment 39-16228 (75 FR 11428, March 11, 2010), for certain
Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-103, B4-203, B4-2C
airplanes; Model A310 series airplanes; and Model A300 B4-601, B4-603,
B4-605R, B4-620, B4-622, and B4-622R airplanes. The AD requires
repetitive inspections to detect cracks of the pylon side panels (upper
section) at rib 8; and corrective actions if necessary.
As published, Table 1 of this AD contained a typographical error in
the second row in the second column. The compliance time of ``>17,500
total flight \1\ '' has been corrected to read ''>17,500 total flight
cycles \1\.'' (The word ``cycles'' was omitted in the AD.)
No other part of the regulatory information has been changed;
therefore, the final rule is not republished in the Federal Register.
The effective date of this AD remains April 15, 2010.

In the Federal Register of March 11, 2010, on page 11430, in the second
