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
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 to the extent that it justifies making a regulatory
distinction; 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.
We prepared an economic evaluation of the estimated costs to comply with this AD and placed it
in the AD docket.

EASA AD No.: 2013-0096
EASA AIRWORTHINESS DIRECTIVE
AD No.: 2013-0096
Date: 18 April 2013
Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation
(EC) No 216/2008 on behalf of the European Community, its Member States and of the
European third countries that participate in the activities of EASA under Article 66 of that
Regulation.
This AD is issued in accordance with EU 748/2012, Part 21.A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the
continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate an
aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency [EC
2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption].
Design Approval Holder’s Name: Type/Model designation(s):
ROLLS-ROYCE PLC Trent 1000 engines
TCDS Number: EASA.E.036
Foreign AD: Not applicable
Supersedure: None
ATA 72 Engine – Intermediate Pressure Turbine Blades – Inspection
Manufacturer(s): Rolls-Royce plc
Applicability: Trent 1000-A, Trent 1000-C, Trent 1000-D, Trent 1000-E, Trent 1000-G and
Trent 1000-H engines, all serial numbers.
These engines are known to be installed on, but not limited to, Boeing 787
series aeroplanes.
Reason: During overhaul and on-wing inspections, Intermediate Pressure Turbine (IPT)
blades Part Number (P/N) FW63838 have been found with missing rear seal
fins. Release of an IPT blade rear seal fin may result in downstream, secondary
damage, potentially accompanied with engine power loss.
This condition, if not detected and corrected, could lead to an in-flight shut-
down resulting in reduced control to the aeroplane.
For the reasons described above, this AD requires repetitive borescope
inspections and, depending on findings, removal from service of the engine.
This AD is considered an interim action, pending the development of a
modification that will enhance the capability of the engine to sustain non-
uniform loads, which is expected to be terminating action for the repetitive
inspections as required by this AD.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company
Model 777 airplanes. This AD was prompted by reports that escape slides/rafts did not deploy due to
galvanic corrosion of the door-mounted slide/raft packboard release mechanisms. This AD requires
doing a general visual inspection of the housing assembly of the packboard release mechanism to
determine if its surface treatment has been sealed, and if the surface of the housing assembly is
unsealed, replacing the housing assembly with a new or serviceable housing assembly. We are
issuing this AD to detect and correct corrosion of the packboard release mechanisms, which could
interfere with escape slide/raft deployment, prohibit doors from opening in the armed mode, and
cause consequent delay and injury during evacuation of passengers and crew from the cabin in the
event of an emergency.
DATES: This AD is effective May 3, 2013.
The Director of the Federal Register approved the incorporation by reference of a certain
publication listed in the AD as of May 3, 2013.

SUPPLEMENTARY INFORMATION:
Discussion
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 published in the Federal Register on January
19, 2012 (77 FR 2666). That NPRM proposed to require doing a general visual inspection of the
housing assembly of the packboard release mechanism to determine if its surface treatment has been
sealed, and if unsealed, replacing the housing assembly with a new or serviceable housing assembly.
Comments
We gave the public the opportunity to participate in developing this AD. The following presents
the comments received on the proposal (77 FR 2666, January 19, 2012), and the FAA's response to
each comment. Boeing supported the NPRM. American Airlines stated that it has incorporated the
requirements of the NPRM into its maintenance program and will continue to do so. United Airlines
(United) did not object to the proposed compliance time.
Request To Allow Verification of Stencil
United requested that we revise the NPRM (77 FR 2666, January 19, 2012) to provide
instructions for inspecting for the accomplishment of Air Cruisers Service Bulletin 777 107-25-30,
dated September 30, 2010, by verifying the stencil of the ''Inspected and/or Mod per S.B. 777 107-25-
30'' on the girt assembly and upper lacing cover. United also requested that we revise the NPRM to
permit operators to demonstrate compliance by means of a technical records review for the
accomplishment of Air Cruisers Service Bulletin 777 107-25-30, dated September 30, 2010.
We agree because, if the modification has been accomplished before the issuance of the AD,
there is no need to duplicate it. We have revised paragraph (g) of this final rule to specify only
slides/rafts that have not been modified using Air Cruisers Service Bulletin 777 107-25-30, dated
September 30, 2010, require the replacement of the housing assembly. We also have added a new
paragraph (h) to this final rule (and re-identified subsequent paragraphs accordingly) to state that
verifying the stencil or a review of technical or maintenance records is acceptable for determining if
the modification has been accomplished.
Request To Revise Service Information
Delta Airlines (Delta) requested that we revise the NPRM (77 FR 2666, January 19, 2012) to
provide instructions stating how to inspect for discrepant unsealed components. Delta stated that the
2
instructions are referenced within a note in Air Cruisers Service Bulletin 777 107-25-30, dated
September 30, 2010. (Boeing Special Attention Service Bulletin 777-25-0507, dated June 30, 2011,
references Air Cruisers Service Bulletin 777 107-25-30, dated September 30, 2010, as an additional
source of guidance for inspecting and installing a new housing assembly of the door-mounted
slide/raft packboard release mechanism.) Delta stated that it is not recommended to have important
instructions listed only within a note.
We disagree with the commenter's request to revise the AD to provide inspection instructions.
We reference the Air Cruisers Service Bulletin as an additional source of guidance for accomplishing
the actions. To delay this AD so manufacturer service information could be revised would be
inappropriate, in light of the identified unsafe condition. We have not changed the AD in this regard.
Request To Extend Compliance Time
Delta expressed concern that the 42-month compliance time would be difficult to meet if
replacement part kits were not available upon the issuance of the AD. We infer from this comment
that Delta is requesting that the 42-month compliance time be extended to allow the part supplier
adequate time to make part kits available.
We disagree with the request to extend the compliance time because we have confirmed that the
supplier has prepared to have parts available and also to support the compliance time of the AD. If
adequate parts are not available as planned approaching the end of the compliance period, paragraph
(j) of this AD provides operators the opportunity to request approval of an alternative compliance
time if data are presented that prove that the alternative compliance time will provide an acceptable
level of safety. We have not changed this AD regarding this issue.
Request To Provide Credit for Previous Actions
United requested that we allow credit for work done prior to the effective date of the AD using
Air Cruisers Service Bulletin 777 107-25-30, dated September 30, 2010, since Air Cruisers Service
Bulletin 777 107-25-30 is now at Revision 1.
We find that no change is necessary because this AD requires that actions be done in accordance
with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-25-0507,
dated June 30, 2011, which references Air Cruisers Service Bulletin 777 107-25-30, dated September
30, 2010, as an additional source of guidance for inspecting and installing a new housing assembly of
the door-mounted slide/raft packboard release mechanism. Boeing has not revised its service bulletin
and, therefore, this AD references the original issue of Air Cruisers Service Bulletin 777 107-25-30,
dated September 30, 2010. We have not changed this AD in this regard.
Explanation of Change Made to This Final Rule
We have changed Note 1 to paragraph (g) of the NPRM (77 FR 2666, January 19, 2012), which
defined a general visual inspection, to new paragraph (i) in the regulatory text of this AD, and re-
identified subsequent paragraphs and notes accordingly.
Conclusion
We reviewed the relevant data, considered the comments received, and determined that air safety
and the public interest require adopting the AD with the changes described previously–and minor
editorial changes. We have determined that these minor changes:
• Are consistent with the intent that was proposed in the NPRM (77 FR 2666, January 19,
2012) for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM
(77 FR 2666, January 19, 2012).
