Airworthiness Directives; Pratt & Whitney Turbofan Engines, 17856-17859 [2014-06953]

Download as PDF 17856 Federal Register / Vol. 79, No. 61 / Monday, March 31, 2014 / Rules and Regulations Title VI of the Appropriations Act supports an interim final rulemaking as the limitation arguably makes formal proposed and final rulemaking procedures ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Further, we believe amending the rule to remove the requirements for non-binding, advisory votes will ensure compliance with the Appropriations Act. Consistent with the Appropriations Act, as well as the Farm Bill, this interim final rulemaking is limited to the advisory vote provisions of the October 3, 2012, (77 FR 60582) rulemaking. Specifically, we are removing the following rule provisions: D § 611.100(a), defining the term ‘‘advisory vote’’; D § 611.360, requiring policies and procedures for non-binding, advisory votes on senior officer compensation; D § 611.410, addressing non-binding, advisory votes on senior officer compensation; D § 620.5(a)(11), requiring disclosure of any advisory votes held during the reporting year at the institution; D § 620.6(c)(6), requiring disclosure (adjacent to the compensation table) in the annual report of a stockholder’s right to petition for a non-binding, advisory vote on senior officer compensation; and D § 630.20(i)(last sentence), requiring disclosure of any advisory votes held during the reporting year within the System. All other regulatory provisions and changes resulting from the October 3, 2012 (77 FR 60582) rulemaking remain in effect. IV. Regulatory Flexibility Act Pursuant to section 605(b) of the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), the FCA hereby certifies that this interim final rule will not have a significant economic impact on a substantial number of small entities. Each of the banks in the System, considered together with its affiliated associations, has assets and annual income in excess of the amounts that would qualify them as small entities. Therefore, System institutions are not ‘‘small entities’’ as defined in the Regulatory Flexibility Act. emcdonald on DSK67QTVN1PROD with RULES PART 611—ORGANIZATION Authority: Secs. 1.2, 1.3, 1.4, 1.5, 1.12, 1.13, 2.0, 2.1, 2.2, 2.10, 2.11, 2.12, 3.0, 3.1, 3.2, 3.3, 3.7, 3.8, 3.9, 3.21, 4.3A, 4.12, 4.12A, 4.15, 4.20, 4.21, 4.25, 4.26, 4.27, 4.28A, 5.9, 5.17, 5.25, 7.0–7.13, 8.5(e) of the Farm Credit Act (12 U.S.C. 2002, 2011, 2012, 2013, 2020, 2021, 2071, 2072, 2073, 2091, 2092, 2093, 2121, 2122, 2123, 2124, 2128, 2129, 2130, 2142, 2154a, 2183, 2184, 2203, 2208, 2209, 2211, 2212, 2213, 2214, 2243, 2252, 2261, 2279a–2279f–1, 2279aa–5(e)); secs. 411 and 412 of Pub.

ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2146, PW2240, PW2337, PW2643, and F117–PW–100 turbofan engines. This AD was prompted by a rupture of the diffuser-to-high-pressure turbine (HPT) case flange. This AD requires a one-time eddy current inspection (ECI) of affected engines with certain diffuser and HPT cases installed. This AD also requires a fluorescentpenetrant inspection (FPI) of the diffuser case rear flange and HPT case front flange. We are issuing this AD to prevent failure of the diffuser-to-HPT case flange, which could lead to uncontained engine failure and damage to the airplane. DATES: This AD is effective May 5, 2014. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 5, 2014.

SUPPLEMENTARY INFORMATION: emcdonald on DSK67QTVN1PROD with RULES Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all PW PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2146, PW2240, PW2337, PW2643, and F117–PW–100 turbofan engines. The NPRM published in the Federal Register on October 29, 2013 (78 FR 64419). The NPRM was prompted by a rupture of the diffuserto-HPT case flange. The NPRM proposed to require a one-time ECI of affected engines with certain diffuser and HPT cases installed and an FPI of the diffuser case rear flange and HPT case front flange. We are issuing this AD to prevent failure of the diffuser-to-HPT case flange, which could lead to uncontained engine failure and damage to the airplane. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal and the FAA’s response to each comment. VerDate Mar<15>2010 16:18 Mar 28, 2014 Jkt 232001 17857 Request Credit for FPI at Piece Part Level deleting diffuser and HPT cases that have been inspected. Delta Air Lines (DAL), PW, Federal Express, and United Parcel Service (UPS) requested that previous FPI of cases at the piece part level be allowed for AD compliance in lieu of ECI. The justification for this request is that FPI of diffuser/HPT cases at the piece part level performed after January 1, 2010 are equivalent to the ECI procedures. We agree. We changed the AD to allow credit for FPI of diffuser and HPT cases performed after January 1, 2010. Request Definition for Piece Part Exposure DAL, UPS, and an individual commenter requested that a definition be provided for ‘‘piece part exposure’’ as it applies to repetitive inspections of diffuser and HPT cases. The reason for this request was to clarify when inspections are required. We agree. We added a definition for ‘‘piece part exposure’’ in this AD. Request to Eliminate Initial Inspection and Mandated Repetitive Inspections DAL and PW requested elimination of inspection for diffuser/HPT cases identified in Table 1 to paragraph (e) of this AD because the inspections have already been completed. DAL and PW also requested that mandated repetitive inspections of the diffuser and HPT case be eliminated since this requirement is already in the engine manual and part of DAL’s PW2000 maintenance program. Mandated inspection results in a quality records burden. The AD is requested to be withdrawn based on these requested actions. We partially agree. We agree that many of the diffuser/HPT case inspections have been completed. PW reports that all diffuser and HPT cases have been inspected except for three. Those three cases are installed on engines not currently in service. We changed the AD to eliminate Table 1 to paragraph (e) of this AD. We added the remaining diffuser cases and HPT cases requiring inspection to paragraph (e) of this AD. We do not agree that mandated inspections for the diffuser and HPT cases are not required as diffuser or HPT case failure may result in a catastrophic aircraft event. We did not change the AD requirement for repetitive inspections. This AD will not be withdrawn. Request to Exclude F117–PW–100 Requirements PW requested that F117–PW–100 requirements not be included in this AD as the inspections will be completed by December 2013. We partially agree. We received confirmation that the diffuser and HPT cases that are applicable to F117–PW– 100 engines have been inspected. However, since the F117–PW–100 engine model has been certified by the FAA and is on the type certificate data sheet, we will require repetitive FPI of the diffuser and HPT cases at piece part opportunity. We changed this AD by PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 Request for New Compliance Method DAL requested that the compliance requirement for repetitive inspections direct operator’s to revise their approved maintenance programs with an FPI of the diffuser and HPT cases and not require documenting AD compliance for each individual case. This change would help to eliminate undue burden on operator/maintenance facility for AD tracking requirements. We partially agree. We agree that changing the continuous airworthiness maintenance program (CAMP) to require diffuser and HPT case inspections adequately addresses our safety concerns. We do not agree that tracking repetitive inspections to show AD compliance is an undue burden. We changed the AD by adding an Optional Terminating Action allowing diffuser and HPT case inspections to be added to the CAMP to satisfy repetitive inspection requirements of this AD. Request FAA Standard Practices, Processes, Consumables, and Standard Tooling be Allowed to Perform ECI One individual commenter requested that only Non-destructive Inspection Procedure sections IX through XVIII be mandated as these sections contain the only items that have an actual effect on the unsafe condition of the AD. We disagree. The specific ECI inspection equipment and procedures developed by PW have been verified as being able to detect cracks in the diffuser case and HPT case M-flange. The specific equipment and procedures must be used to ensure proper inspection results. However, operators and maintenance facilities can propose use of other equipment and/or procedures as an alternative method of compliance if they can validate equivalent results. We did not change this AD. Request Clarification for Applicability The same individual commenter requested clarification that the Compliance paragraph apply to all HPT E:\FR\FM\31MRR1.SGM 31MRR1 17858 Federal Register / Vol. 79, No. 61 / Monday, March 31, 2014 / Rules and Regulations and diffuser cases regardless of whether they are listed in Table 1 to paragraph (e) or not. The reason for this request is that it is unclear if the repetitive inspections are required only for those cases specified in Table 1. We agree. We deleted Table 1 to paragraph (e) of this AD and added the remaining diffuser cases and HPT cases requiring inspection to paragraph (e) of this AD. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 64419, October 29, 2013) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 64419, October 29, 2013). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. emcdonald on DSK67QTVN1PROD with RULES Costs of Compliance We estimate that this AD will affect 638 engines installed on airplanes of U.S. registry. Of the 638 engines, we estimate that about 3 engines will be subject to ECI and all engines will be subject to the FPI. We also estimate that it will take about 5 hours to perform the ECI and 3 hours to perform the FPI required by this AD. Materials cost for the FPI will be about $20 per engine. The average labor rate is $85 per hour. Based on these figures, we estimate the total cost of this AD to U.S. operators is $176,725. 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 VerDate Mar<15>2010 16:18 Mar 28, 2014 Jkt 232001 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.

[FR Doc. 2014–06959 Filed 3–28–14; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF HEALTH AND HUMAN SERVICES Food and Drug Administration 21 CFR Part 558 On January 21, 2014, a final rule for FAA Docket No. FAA–2012–0661, Airspace Docket No. 09–AWA–4, was published in the Federal Register (79 FR 3305) to amend the Detroit Class B airspace area. The Detroit Class B airspace area was modified to contain aircraft conducting published instrument procedures at Detroit Metropolitan Wayne County Airport (DTW) within Class B airspace, enhance safety, improve the flow of air traffic, and reduce the potential for midair collisions in the DTW terminal area, while accommodating the concerns of all airspace users. Subsequent to publication of the rule, the FAA determined the boundary segment described in Area A, from lat. 42°17′18″ N., long. 83°27′27″ W. on the 4.4-mile radius of the Detroit Willow Run Airport to lat. 42°20′47″ N., long. 83°22′12″ W. on the 8-mile arc of the DXO VOR/DME, and the boundary segment described in Area B, from the intersection of the DXO VOR/DME 354° radial and the Detroit Willow Run Airport 047° bearing to lat. 42°20′47″ N., long. 83°22′12″ W., did not align as intended and contained a gap between the two adjacent subareas. The FAA is correcting this minor error by adding the geographic point defined by the intersection of the DXO VOR/DME 354° radial and the Detroit Willow Run Airport 047° bearing in the Area A description to remove the gap.

14 CFR Part 39

[Docket No. FAA-2013-0740; Directorate Identifier 2013-NE-24-AD; 
Amendment 39-17804; AD 2014-05-32]
RIN 2120-AA64


Airworthiness Directives; Pratt & Whitney Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, 
PW2146, PW2240, PW2337, PW2643, and F117-PW-100 turbofan engines. This 
AD was prompted by a rupture of the diffuser-to-high-pressure turbine 
(HPT) case flange. This AD requires a one-time eddy current inspection 
(ECI) of affected engines with certain diffuser and HPT cases 
installed. This AD also requires a fluorescent-penetrant inspection 
(FPI) of the diffuser case rear flange and HPT case front flange. We 
are issuing this AD to prevent failure of the diffuser-to-HPT case 
flange, which could lead to uncontained engine failure and damage to 
the airplane.

DATES: This AD is effective May 5, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 5, 2014.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all PW PW2037, PW2037D, 
PW2037M, PW2040, PW2040D, PW2043, PW2146, PW2240, PW2337, PW2643, and 
F117-PW-100 turbofan engines. The NPRM published in the Federal 
Register on October 29, 2013 (78 FR 64419). The NPRM was prompted by a 
rupture of the diffuser-to-HPT case flange. The NPRM proposed to 
require a one-time ECI of affected engines with certain diffuser and 
HPT cases installed and an FPI of the diffuser case rear flange and HPT 
case front flange. We are issuing this AD to prevent failure of the 
diffuser-to-HPT case flange, which could lead to uncontained engine 
failure and damage to the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
and the FAA's response to each comment.

Request Credit for FPI at Piece Part Level

    Delta Air Lines (DAL), PW, Federal Express, and United Parcel 
Service (UPS) requested that previous FPI of cases at the piece part 
level be allowed for AD compliance in lieu of ECI. The justification 
for this request is that FPI of diffuser/HPT cases at the piece part 
level performed after January 1, 2010 are equivalent to the ECI 
procedures.
    We agree. We changed the AD to allow credit for FPI of diffuser and 
HPT cases performed after January 1, 2010.

Request to Eliminate Initial Inspection and Mandated Repetitive 
Inspections

    DAL and PW requested elimination of inspection for diffuser/HPT 
cases identified in Table 1 to paragraph (e) of this AD because the 
inspections have already been completed. DAL and PW also requested that 
mandated repetitive inspections of the diffuser and HPT case be 
eliminated since this requirement is already in the engine manual and 
part of DAL's PW2000 maintenance program. Mandated inspection results 
in a quality records burden. The AD is requested to be withdrawn based 
on these requested actions.
    We partially agree. We agree that many of the diffuser/HPT case 
inspections have been completed. PW reports that all diffuser and HPT 
cases have been inspected except for three. Those three cases are 
installed on engines not currently in service. We changed the AD to 
eliminate Table 1 to paragraph (e) of this AD. We added the remaining 
diffuser cases and HPT cases requiring inspection to paragraph (e) of 
this AD.
    We do not agree that mandated inspections for the diffuser and HPT 
cases are not required as diffuser or HPT case failure may result in a 
catastrophic aircraft event. We did not change the AD requirement for 
repetitive inspections. This AD will not be withdrawn.

Request to Exclude F117-PW-100 Requirements

    PW requested that F117-PW-100 requirements not be included in this 
AD as the inspections will be completed by December 2013.
    We partially agree. We received confirmation that the diffuser and 
HPT cases that are applicable to F117-PW-100 engines have been 
inspected. However, since the F117-PW-100 engine model has been 
certified by the FAA and is on the type certificate data sheet, we will 
require repetitive FPI of the diffuser and HPT cases at piece part 
opportunity. We changed this AD by deleting diffuser and HPT cases that 
have been inspected.

Request Definition for Piece Part Exposure

    DAL, UPS, and an individual commenter requested that a definition 
be provided for ``piece part exposure'' as it applies to repetitive 
inspections of diffuser and HPT cases. The reason for this request was 
to clarify when inspections are required.
    We agree. We added a definition for ``piece part exposure'' in this 
AD.

Request for New Compliance Method

    DAL requested that the compliance requirement for repetitive 
inspections direct operator's to revise their approved maintenance 
programs with an FPI of the diffuser and HPT cases and not require 
documenting AD compliance for each individual case. This change would 
help to eliminate undue burden on operator/maintenance facility for AD 
tracking requirements.
    We partially agree. We agree that changing the continuous 
airworthiness maintenance program (CAMP) to require diffuser and HPT 
case inspections adequately addresses our safety concerns.
    We do not agree that tracking repetitive inspections to show AD 
compliance is an undue burden. We changed the AD by adding an Optional 
Terminating Action allowing diffuser and HPT case inspections to be 
added to the CAMP to satisfy repetitive inspection requirements of this 
AD.

Request FAA Standard Practices, Processes, Consumables, and Standard 
Tooling be Allowed to Perform ECI

    One individual commenter requested that only Non-destructive 
Inspection Procedure sections IX through XVIII be mandated as these 
sections contain the only items that have an actual effect on the 
unsafe condition of the AD.
    We disagree. The specific ECI inspection equipment and procedures 
developed by PW have been verified as being able to detect cracks in 
the diffuser case and HPT case M-flange. The specific equipment and 
procedures must be used to ensure proper inspection results. However, 
operators and maintenance facilities can propose use of other equipment 
and/or procedures as an alternative method of compliance if they can 
validate equivalent results. We did not change this AD.

Request Clarification for Applicability

    The same individual commenter requested clarification that the 
Compliance paragraph apply to all HPT

[[Page 17858]]

and diffuser cases regardless of whether they are listed in Table 1 to 
paragraph (e) or not. The reason for this request is that it is unclear 
if the repetitive inspections are required only for those cases 
specified in Table 1.
    We agree. We deleted Table 1 to paragraph (e) of this AD and added 
the remaining diffuser cases and HPT cases requiring inspection to 
paragraph (e) of this AD.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
     [Agr]re consistent with the intent that was proposed in 
the NPRM (78 FR 64419, October 29, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 64419, October 29, 2013).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD will affect 638 engines installed on 
airplanes of U.S. registry. Of the 638 engines, we estimate that about 
3 engines will be subject to ECI and all engines will be subject to the 
FPI. We also estimate that it will take about 5 hours to perform the 
ECI and 3 hours to perform the FPI required by this AD. Materials cost 
for the FPI will be about $20 per engine. The average labor rate is $85 
per hour. Based on these figures, we estimate the total cost of this AD 
to U.S. operators is $176,725.

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.
