Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2011–0080,
dated May 6, 2011 (referred to after this
as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
Routine inspections have revealed cracking
on the head sections of two Trent 800 front
combustion liners.
This condition, if not detected and
corrected, could lead to hot gas breakout with
subsequent downstream component release
potentially leading to uncontained high
energy debris, possibly resulting in damage
to the aeroplane or injury to persons on the
ground.
We are proposing this AD to prevent
uncontained engine failure and damage
to the airplane.
Relevant Service Information
Rolls-Royce plc has issued Alert
Service Bulletin RB.211–72–AG456,
dated September 9, 2010. The actions
described in this service information are
intended to correct the unsafe condition
identified in the MCAI.

FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of the United
Kingdom, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the United
Kingdom, they have notified us of the
unsafe condition described in the MCAI
and service information referenced
above. We are proposing this AD
because we evaluated all information
provided by EASA, and determined the
unsafe condition exists and is likely to
exist or develop on other products of the
same type design.
Costs of Compliance
We estimate that this proposed AD
would affect about 125 products of U.S.
registry. We also estimate that it would
take about 10 work-hours per product to
inspect and 10 additional work-hours
for those combustion liners that require
replacement. The average labor rate is
$85 per work-hour. Required parts
would cost about $525,000 per product.
We expect that four front combustion
liners will require replacement. Based
on these figures, we estimate the cost of
the proposed AD on U.S. operators to be
$2,209,650.
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 proposed AD
would not have federalism implications
under Executive Order 13132. This
proposed AD would 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.

Federal Register / Vol. 76, No. 227 / Friday, November 25, 2011 / Proposed Rules
For the reasons discussed above, I
certify this proposed regulation:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
2. Is not a ‘‘significant rule’’ under the
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 proposed AD and placed it in the
AD docket.

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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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.
[[Page 72652]]
For the reasons discussed above, I certify this proposed
regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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 proposed AD and placed it in the AD docket.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
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]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Rolls-Royce plc: Docket No. FAA-2011-0959; Directorate Identifier
2011-NE-25-AD.
(a) Comments Due Date
We must receive comments by January 24, 2012.
(b) Affected Airworthiness Directives (ADs)
None.
(c) Applicability
This AD applies to Rolls-Royce plc (RR) RB211 Trent 800 turbofan
engines, all models, all serial numbers.
(d) Reason
(1) This AD results from mandatory continuing airworthiness
information (MCAI) issued by an aviation authority of another
country to identify and correct an unsafe condition on an aviation
product. The MCAI describes the unsafe condition as:
Routine inspections have revealed cracking on the head sections
of two Trent 800 front combustion liners.
This condition, if not detected and corrected, could lead to hot
gas breakout with subsequent downstream component release
potentially leading to uncontained high energy debris, possibly
resulting in damage to the aeroplane or injury to persons on the
ground.
(2) We are issuing this AD to prevent uncontained engine failure
and damage to the airplane.
(e) Actions and Compliance
Unless already done, do the following actions.
(f) Initial Inspection
(1) Within 1,000 flight cycles (FCs) after the effective date of
this AD, inspect the front combustion liner head section for
cracking. Use paragraph 3.A, except for 3.A.(1)(a)(i), of the On-
Wing Accomplishment Instructions of RR Alert Service Bulletin (ASB)
RB.211-72-AG456, dated September 9, 2010, to do your inspections.
(2) If you find cracking, remove the front combustion liner head
section from service at the next shop visit. Until the next shop
visit, take the corrective actions listed in Table 1 of this AD, as
applicable.
Table 1--Inspection Findings and Follow-On Actions
------------------------------------------------------------------------
Action(s) and compliance
Inspection findings time(s)
------------------------------------------------------------------------
(i) Cumulative crack length up to 150 Reduce the inspection intervals
mm (up to 2 heatshields). to 250 FCs.
(ii) Cumulative crack length 150 mm to Reduce the inspection intervals
300 mm (up to 4 heatshields). to 100 FCs.
(iii) Cumulative crack length 300 mm to Remove the engine within 50
450 mm (up to 6 heatshields). FCs.
(iv) Cumulative crack length 450 mm to Replace the engine within 5
900 mm (up to 12 heatshields). FCs.
(v) Cumulative crack length greater Replace the engine before next
than 900 mm (more than 12 heatshields). flight.
------------------------------------------------------------------------
(g) Repetitive Inspections
(1) At intervals not to exceed 2,000 FCs, inspect the front
combustion liner head section for cracking. Use paragraph 3.A,
except for 3.A.(1)(a)(i), of the On-Wing Accomplishment Instructions
of RR ASB RB.211-72-AG456, dated September 9, 2010, to do your
inspection.
(i) If you find cracking, remove the front combustion liner head
section at the next shop visit. Until the next shop visit, take the
corrective actions as detailed in Table 1 of this AD, as applicable.
(2) For engines not found to have cracks in the front combustion
liner head section in accordance with paragraphs (f)(1), (f)(2), or
(g)(1) of this AD, at every shop visit after the effective date of
this AD, inspect the front combustion liner head section for
cracking. Use paragraph B.(2), except B.(2)(a)(i), of the In-shop
Accomplishment Instructions of RR ASB RB.211-72-AG456, dated
September 9, 2010, to do the inspections.
(3) Accomplishment of a shop visit inspection as required by
paragraph (g)(2) of this AD may substitute for the accomplishment of
an on-wing inspection as required by paragraph (f)(1) or (g)(1) of
this AD.
(h) Definition of Shop Visit
For the purpose of this AD, the term shop visit means the
induction of an engine into the shop for maintenance where the front
combustion liner is exposed or when the engine has been removed from
service as a result of paragraph (f)(2) or (g)(1)(i) of this AD.
(i) Alternative Methods of Compliance (AMOCs)
The Manager, Engine Certification Office, FAA, has the authority
to approve AMOCs for this AD, if requested using the procedures
found in 14 CFR 39.19.
