Turboprop Engines Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede airworthiness directive (AD) 2006–15– 08, which applies to all Honeywell International Inc. TPE331–1, –2, –2UA, –3U, –3UW, –5, –5A, –5AB, –5B, –6, –6A, –10, –10AV, –10GP, –10GT, –10P, –10R, –10T, –10U, –10UA, –10UF, –10UG, –10UGR, –10UR, –11U, –12JR, –12UA, –12UAR, and –12UHR turboprop engines with certain part numbers (P/Ns) of Woodward fuel control unit (FCU) assemblies, installed. AD 2006–15–08 currently requires initial and repetitive dimensional inspections of the fuel control drive spline for wear, and replacement of the FCU and fuel pump. Since we issued AD 2006–15–08, we determined that additional FCU assembly P/Ns are affected, the compliance deadline and assembly replacement after removal for cause or overhaul are no longer required, and that cautionary engine operating information must be observed. This proposed AD was prompted by reports of loss of the fuel control drive, leading to engine overspeed, overtorque, overtemperature, uncontained rotor failure, and asymmetric thrust in multiengine airplanes. This proposed AD would require initial and repetitive dimensional inspections of the affected fuel control drive splines, and insertion of certain airplane operating procedures into the applicable flight manuals.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On July 14, 2006, we issued AD 2006– 15–08, Amendment 39–14688 (71 FR 41121, July 20, 2006), for all Honeywell International Inc. TPE331 series turboprop engines with certain P/Ns of Woodward FCU assemblies installed. AD 2006–15–08 requires initial and repetitive dimensional inspections of the fuel control drive spline for wear that might cause replacement of the FCU and/or fuel pump assemblies. AD 2006–15–08 also requires the replacement of the FCU assembly when the FCU is removed for cause or overhaul, but not later than December 31, 2012. AD 2006–15–08 was prompted by fuel control drive failures that resulted in a rapid, uncommanded, uncontrolled increase in fuel flow and overspeed of the engine during ground start. We issued AD 2006–15–08 to prevent failure of the fuel control drive, destructive overspeed that could result in uncontained rotor failure and damage to the airplane. Actions Since AD 2006–15–08 Was Issued Since we issued AD 2006–15–08, Amendment 39–14688 (71 FR 41121, July 20, 2006), we determined that additional FCU assembly P/Ns are affected, certain repetitive fuel control drive inspections are necessary, and that additional flight crew emergency procedures and warnings are required. The warnings are required to inform flight crew of the probable engine response(s) following a loss of drive between the engine driven fuel pump and fuel control governor system. These engine responses are dependent on the phase of operation (ground engine start, ground or flight operations). Also since we issued AD 2006–15–08, Amendment 39–14688 (71 FR 41121, July 20, 2006), we reviewed the inservice trends and engine in-flight shutdowns (IFSDs) caused by the PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 modified FCU and determined that the IFSD rate had not improved and the installation of the modified FCU assembly was not required. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require continued dimensional spline inspections required by AD 2006–15– 08, add new P/Ns of affected FCU assemblies that require dimensional spline inspections. This proposed AD would require insertion of uncommanded engine overspeed procedures into the Airplane Flight Manual, Pilot Operating Handbook, and or Manufacturer’s Operating Manual. This proposed AD would retain some but not all requirements of AD 2006– 15–08, (71 FR 41121, July 20, 2006), but would no longer require the installation of a modified FCU. Costs of Compliance We estimate that this proposed AD would affect 2,250 engines installed on airplanes of U.S. registry. We estimate that it would take 8 hours per engine to perform an FCU inspection, and three inspections will be required over the life of the product. The average labor rate is $85 per hour. Due to the more frequent inspections proposed by this AD, we estimate 10% of affected engines would require FCU assembly stub shaft replacement, fuel pump or fuel control repair. We also estimate that repairs should not exceed $10,000 per engine. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $6,307,044. 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 E:\FR\FM\19MRP1.SGM 19MRP1 Federal Register / Vol. 79, No. 53 / Wednesday, March 19, 2014 / Proposed Rules 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. (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. Regulatory Findings We have 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. For the reasons discussed above, I certify that the 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), (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, and List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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. § 39.13 [Amended] 2.

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 2012–0103, dated June 11, 2012 (corrected June 19, 2012) (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: During maintenance checks, cracks were discovered by A300 and A300–600 operators in the frame [base] feet fittings, connecting the frame lower positions to the centre wing box. These occurrences were followed by a dedicated sampling inspection programme carried out by Airbus. During this sampling programme, 22 A300–600 aeroplanes were found with cracks on the lower fittings of frame 44 to frame 46 left hand (LH) and right hand (RH) side. This condition, if not detected and corrected, could affect the structural integrity of the fuselage of all aeroplanes operated up to the extended service goal (ESG). For the reasons described above, this [EASA] AD requires repetitive detailed visual inspections [for discrepancies (cracking)] of the lower frame fittings between frame 41 and frame 46 and, depending on findings, accomplishment of a repair. This [EASA] AD has been republished to correct Note 2 in Appendix 1. Related investigative actions include doing a rotating probe inspection for cracking of the crack stop hole. Corrective actions include repairing or replacing cracking and cracked base fittings. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating it in Docket No. FAA– 2014–0143. Relevant Service Information Airbus has issued Mandatory Service Bulletin A300–53–6111, Revision 05, including Appendix 01, dated January 28, 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. E:\FR\FM\19MRP1.SGM 19MRP1

Airworthiness Directives; Honeywell International Inc. Turboprop
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directive (AD) 2006-15-
08, which applies to all Honeywell International Inc. TPE331-1, -2, -
2UA, -3U, -3UW, -5, -5A, -5AB, -5B, -6, -6A, -10, -10AV, -10GP, -10GT,
-10P, -10R, -10T, -10U, -10UA, -10UF, -10UG, -10UGR, -10UR, -11U, -
12JR, -12UA, -12UAR, and -12UHR turboprop engines with certain part
numbers (P/Ns) of Woodward fuel control unit (FCU) assemblies,
installed. AD 2006-15-08 currently requires initial and repetitive
dimensional inspections of the fuel control drive spline for wear, and
replacement of the FCU and fuel pump. Since we issued AD 2006-15-08, we
determined that additional FCU assembly P/Ns are affected, the
compliance deadline and assembly replacement after removal for cause or
overhaul are no longer required, and that cautionary engine operating
information must be observed. This proposed AD was prompted by reports
of loss of the fuel control drive, leading to engine overspeed,
overtorque, overtemperature, uncontained rotor failure, and asymmetric
thrust in multi-engine airplanes. This proposed AD would require
initial and repetitive dimensional inspections of the affected fuel
control drive splines, and insertion of certain airplane operating
procedures into the applicable flight manuals. We

[[Page 15262]]

are proposing this AD to prevent failure of the fuel control drive that
could result in damage to the engine and airplane.

DATES: We must receive comments on this proposed AD by May 19, 2014.

Discussion

On July 14, 2006, we issued AD 2006-15-08, Amendment 39-14688 (71
FR 41121, July 20, 2006), for all Honeywell International Inc. TPE331
series turboprop engines with certain P/Ns of Woodward FCU assemblies
installed. AD 2006-15-08 requires initial and repetitive dimensional
inspections of the fuel control drive spline for wear that might cause
replacement of the FCU and/or fuel pump assemblies. AD 2006-15-08 also
requires the replacement of the FCU assembly when the FCU is removed
for cause or overhaul, but not later than December 31, 2012. AD 2006-
15-08 was prompted by fuel control drive failures that resulted in a
rapid, uncommanded, uncontrolled increase in fuel flow and overspeed of
the engine during ground start. We issued AD 2006-15-08 to prevent
failure of the fuel control drive, destructive overspeed that could
result in uncontained rotor failure and damage to the airplane.

Actions Since AD 2006-15-08 Was Issued

Since we issued AD 2006-15-08, Amendment 39-14688 (71 FR 41121,
July 20, 2006), we determined that additional FCU assembly P/Ns are
affected, certain repetitive fuel control drive inspections are
necessary, and that additional flight crew emergency procedures and
warnings are required. The warnings are required to inform flight crew
of the probable engine response(s) following a loss of drive between
the engine driven fuel pump and fuel control governor system. These
engine responses are dependent on the phase of operation (ground engine
start, ground or flight operations).
Also since we issued AD 2006-15-08, Amendment 39-14688 (71 FR
41121, July 20, 2006), we reviewed the in-service trends and engine in-
flight shutdowns (IFSDs) caused by the modified FCU and determined that
the IFSD rate had not improved and the installation of the modified FCU
assembly was not required.

FAA's Determination

We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

This proposed AD would require continued dimensional spline
inspections required by AD 2006-15-08, add new P/Ns of affected FCU
assemblies that require dimensional spline inspections. This proposed
AD would require insertion of uncommanded engine overspeed procedures
into the Airplane Flight Manual, Pilot Operating Handbook, and or
Manufacturer's Operating Manual. This proposed AD would retain some but
not all requirements of AD 2006-15-08, (71 FR 41121, July 20, 2006),
but would no longer require the installation of a modified FCU.

Costs of Compliance

We estimate that this proposed AD would affect 2,250 engines
installed on airplanes of U.S. registry. We estimate that it would take
8 hours per engine to perform an FCU inspection, and three inspections
will be required over the life of the product. The average labor rate
is $85 per hour. Due to the more frequent inspections proposed by this
AD, we estimate 10% of affected engines would require FCU assembly stub
shaft replacement, fuel pump or fuel control repair. We also estimate
that repairs should not exceed $10,000 per engine. Based on these
figures, we estimate the cost of this proposed AD on U.S. operators to
be $6,307,044.

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

[[Page 15263]]

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 have 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.
For the reasons discussed above, I certify that the 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),
(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.
