Airworthiness Directives; Airbus Helicopters Deutschland GmbH
Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2007-26-51
which applied to certain Airbus Helicopters Deutschland GmbH Model
EC135 helicopters. AD 2007-26-51 required inspecting the tail rotor
control rod (control rod) and ball pivot and, depending on findings,
replacing those parts. This new AD requires inspecting certain ball
pivots, applying corrosion preventative compound on the ball pivot, and
corrective action, as applicable. This AD also requires replacing the
control rod with a newly developed control rod. This AD was prompted by
the manufacturer's development of a new control rod, which the FAA has
determined must be installed in order to address the identified unsafe
condition. The actions of this AD are intended to address an unsafe
condition on these products.

DATES: This AD is effective January 22, 2021.
    The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 22,
2021.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to remove AD 2007-26-51, Amendment 39-15357 (73 FR 6008,
February 1, 2008) (AD 2007-26-51), and add a new AD. AD 2007-26-51
applied to certain Airbus Helicopters Deutschland GmbH (type
certificate previously held by Eurocopter Deutschland GmbH) Model EC135
helicopters, serial number (S/N) 0005 up to and including S/N 0444,
except S/N 0028, and with control rod part number (P/N) L672M2005207,
installed. The NPRM was published in the Federal Register on June 18,
2020 (85 FR 36816). The NPRM proposed to require inspecting certain
ball pivots for damage and freedom of movement, applying corrosion
preventative compound on the ball pivot, and corrective action, as
applicable. The NPRM also proposed to require replacing the control rod
with the newly developed control rod that the FAA determined was
necessary to address the unsafe condition.
    The NPRM was prompted by EASA AD No. 2010-0227R1, dated April 7,
2017 (referred to after this as the Mandatory Continuing Airworthiness
Information, or ``the MCAI''), issued by EASA, which is the Technical
Agent for the Member States of the European Union, to correct an unsafe
condition for all Model EC135 P1, EC135 P2, EC135 P2+, EC135 T1, EC 135
T2, and EC135 T2+ helicopters; and Model EC635 T1, EC635 P2+, and EC635
T2+ helicopters. EASA advises that in 2007 an accident occurred on an
EC135 helicopter in Japan. Preliminary investigation results indicated
that loss of control was due to failure of the control rod. EASA issued
EASA Emergency AD 2007-0301-E, dated December 13, 2007 (EASA AD 2007-
0301-E) to inspect the affected control rod P/N L672M2005207 and the
ball pivot (which correspond to the actions required by AD 2007-26-51).
EASA AD 2007-0301-E was subsequently superseded by EASA AD 2007-0313,
dated December 21, 2007, to require repetitive inspections and,
depending on findings, the replacement of the control rod and ball
pivot, only for helicopters not equipped with an automatic flight
control system (AFCS). After review of the inspection results, EASA
issued EASA AD 2008-0064, dated April 4, 2008, and later revised to
EASA AD 2008-0064 R1, dated April 15, 2008 (EASA AD 2008-0064 R1), to
apply the requirements to helicopters equipped with an AFCS.
    EASA also advises that after EASA AD 2008-0064R1 was issued,
Eurocopter Deutschland GmbH developed a new control rod P/N
L672M2006101, installation of which constituted terminating action for
the repetitive inspections. Consequently, EASA issued EASA AD 2010-
0227, dated November 3, 2010, and corrected November 8, 2010, retaining
the requirements of EASA AD 2008-0064R1, and requiring the replacement
of control rod P/N L672M2005207 with the new control rod P/N
L672M2006101. The FAA has determined that this new control rod must be
installed in order to address the unsafe condition.
    In addition, EASA advises that following a review of data and
feedback received from in-service helicopters, it

has been determined that the repetitive inspections of the ball pivot
are no longer required to address the unsafe condition. The repetitive
inspections of the ball pivot are now included in Chapter 05 of the
aircraft maintenance manual. Therefore, EASA issued EASA AD 2010-0227R1
to remove the requirement for repetitive inspections of the control rod
and of the ball pivot.
    You may examine the MCAI in the AD docket on the internet at
https://www.regulations.gov by searching for and locating Docket No.
FAA-2020-0572.

Comments

    The FAA gave the public the opportunity to participate in
developing this final rule, but the FAA did not receive any comments on
the NPRM or on the determination of the cost to the public.

FAA's Determination

    These helicopters have been approved by EASA and are approved for
operation in the United States. Pursuant to the FAA's bilateral
agreement with the European Union, EASA has notified the FAA of the
unsafe condition described in its AD. The FAA is issuing this AD after
evaluating all of the information provided by EASA and determining the
unsafe condition exists and is likely to exist or develop on other
helicopters of the same type designs and that air safety and the public
interest require adopting the AD requirements as proposed.

Differences Between This AD and the MCAI or Service Information

    The MCAI includes a compliance time of 50 flight hours for the
inspection of a certain ball pivot; 100 flight hours or 43 days for the
inspection of a certain other ball pivot; and 400 flight hours or 12
months for the replacement of the control rod. This AD requires all
actions be accomplished within 50 hours time-in-service.
    The MCAI applies to Airbus Helicopters Deutschland GmbH Model EC635
T1, EC635 P2+, and EC635 T2+ helicopters. Model EC635 T1, EC635 P2+,
and EC635 T2+ helicopters are not certified by the FAA and are not
included on the U.S. type certificate data sheet except where the U.S.
type certificate data sheet explains that the Model EC635T2+ helicopter
having serial number 0858 was converted from Model EC635T2+ to Model
EC135T2+; this AD therefore does not include those Model EC 635
helicopters in the applicability.
    Additionally, although the MCAI and service information specify to
contact the manufacturer, this AD does not include that requirement.

Related Service Information Under 1 CFR Part 51

    Airbus Helicopters has issued Alert Service Bulletin ASB EC135-67A-
017, Revision 4, dated April 3, 2017, including the Appendix
(watermarked as Appendix to SB EC135-67A-017 Revision 4). This service
information describes procedures for, among other actions, an
inspection of ball pivots, P/Ns 92-201-00 and 92-207-00, for freedom of
movement, and for damage (e.g., cracks, missing hardware, loose
bearing, or play), application of corrosion preventative compound, and
corrective actions. Corrective actions include replacing the ball pivot
and the control rod with serviceable parts, and applying corrosion
preventative compound.
    This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.

Other Related Service Information

    Eurocopter has issued Service Bulletin EC135-67-018, Revision 01,
dated May 15, 2008, which describes procedures for replacing the
control rod having P/N L672M2005207 with a control rod having P/N
L672M2006101.
    Eurocopter has also issued Alert Service Bulletin EC135-67A-017,
Revision 03, dated July 26, 2010, which describes procedures for ball
pivot inspections and replacements.

Costs of Compliance

    The FAA estimates that this AD affects 311 helicopters of U.S.
Registry. The FAA estimates that operators may incur the following
costs in order to comply with this AD. Labor costs are estimated at $85
per work-hour.
    Inspecting the ball pivot takes about 1 work-hour, for an estimated
cost of $85 per helicopter and $26,435 for the U.S. fleet. If
applicable, applying corrosion preventative compound takes a minimal
amount of additional time for a nominal cost.
    Replacing the control rod takes about 3 work-hours, and parts cost
about $800 for an estimated cost of $1,055 per helicopter and $328,105
for the U.S. fleet.
    Replacing the control rod and ball pivot takes up to about 6 work-
hours, and parts cost up to about $2,150 for an estimated cost of up to
$2,660 per helicopter.

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.
    The FAA is 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

    The FAA has determined that 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) Will not affect intrastate aviation in Alaska, 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.

EFED will ideally add Tier 2 GW needs and conceptual model to the agenda for the January meeting - Will be covered in April - see Betsy Behl comments.

Mark Cheplick to post details of code changes in PRZM on this and slides showing impact of changes on the list server. EXPRESS now available.  Wenlin Chen instigated code changes also now available.

Don will circulate an Excel spreadsheet of combined databases when available - aiming for the end of month  (Don will circulate an Excel spreadsheet of combined databases when available - aiming for the end of month  ) - PH to remind Don about this and the earlier action - Done

Michael Barret still to circulate PGW database templates (last meeting) and, if appropriate, Michael will arrange for a discussion topic on this at the January EMWG - still under way

Don Wauchope to post the proposal or the soil dissipation meeting at ACS anaheim (spring 2004) on the FIFRA-EMWG list server. Still to do.

Ron Parker to update FIFRA EMWG on progress of the FAO comparative model at the next meeting - delay till next meeting.

A demonstration of the EFED database will be given I possible at the January meeting - some budgetary issues, work still under way - may be given in April.

Michael Barrett to add a discussion of the details of the kinetics policy to the agenda of the first FIFRA EMWG after management has approved the draft as well as circulating the proposal itself. - awaiting approval

Industry to present the findings of the FOCUS kinetics group at the same meeting - see later

All speakers ideally to provide copies of their presentations to Michael Barrett - Michael to announce new file availability on web site by list server - Optional but nice to do

EPA to consider adding a presentation on the work done internally on Foliar degradation, washoff and extraction factors as well as chemical application method factors for PRZM.  Industry may also develop presentations.  See later presentation.

EPA to review CARES and PLUS - add CARES as a standard topic for updates to future meetings - start at April meeting.

Brief Updates

PRZM-EXAMS model/ EXPRESS

EXPRESS Users manual still under development, internal review of EXPRESS will follow.  A finalized version of PRZM version 3.12 is due for approval - this will be completed when the projects budget is worked out.  3.12 Beta is still the "approved version".  Access to older versions of PRZM EXAMS will also be improved - All comments on version differences should be sent round via the list server.

Frequent teleconferences have been held between OPP and ORD on PRZM/EXAMS.  Recent topic was volatilisation.  David Jones reports that some inconsistencies have been found and the routines appear to be poorly validated.

Industry has put the evaluation of EXPRESS on hold pending resolution of a bug found by Tamara Estes that seems to be due to some truncation issues.  If this is an issue also for EFED (this seems to be the case), it is important to resolve this soon.  Action for Mark Cheplick, Tammara Estes to ensure this is tracked down.

PE4 - EFED Shell

The shell has been refined and minor changes have been made.  Ian Kennedy reported the ability to set the application date relative to emergence date has been added.  It is clear that the PE4 Shell will remain the tool used by EPA exposure assessments for at least the next 4 or 5 months.

The 50+ scenarios are under review presently and EPA findings from the review of public/industry comments will be discussed by the EFED WQ tech team shortly.  Action - They will report back to the next EMWG meeting.

Groundwater

Betsy Behl reported that OPP, USGS (Jack Barbash et al) and others are working together to evaluate seven models, HYDRUS 2D, PRZM, LeachM , LeachP, RZWQM98, GLEAMS, BS2D being run with data from two PGW sites.  This group will report back on progress to EMWG next time.  Barbash has prepared a tool to try to make sure that "internal model settings" are comparable.

PMRA are using LEACHM model presently and are developing scenarios for GW subsurface. A guidance document is being prepared.

Regional Percent Crop area

A policy refinement has been approved regarding the use of 0.87 default for minor crops.  These have been reviewed regionally (HUC2 - major basins - as this is judged suitable & conservative for water issues) to produce local max PCA values (e.g. CA uses 0.56).  This data was generated in the original evaluation of a national maximum.

The data should be made available soon (via Web site?)

Scientist to Scientist Drinking Water treatment Workshop

EPA OPP, OWOW, CLA, University Connecticut, NRDC, many others will attend meeting at end of January by invitation.  This is intended to be a brainstorming session and hence the numbers of attendees were kept low; all groups will need to take care to report the meeting findings back to their constituents to ensure the meeting findings are communicated most effectively.

ACS Soil Dissipation Meeting ACS Anaheim 2004-01-06

Don Wauchope and Al Barefoot are co-organizers for this symposium, which will focus on next steps following the workshop from 2002; there will be four talks from EPA and PMRA.  It is hoped that revised guidance on TFSD studies will be finalized later in 2004.

FOCUS Kinetics Work Group Findings

Russell Jones (BayerCropScience) and Claude Beigel (BASF) made two presentations.  Russell provided an overview of the concepts behind the FOCUS approaches while Claude examined the findings of the FOCUS subgroup on metabolite formation and decline.

Questions focused mainly on the details of some of the examples given by both speakers.  The topic of the formation fraction of metabolites generated considerable discussion.  The development of harmonized standard flow charts seems likely to reduce procedural debates and to standardise reporting and explication.  It was clear that "experts" are likely to apply expert judgement differently on some data sets - and there is still an element of artistry in the effective calculation of sensible kinetics data.

There may be a need for a standardised software package to reduce concerns about uniform encoding of the fitting models in standard mathematical software packages.  The background thinking might make a useful agenda topic at an upcoming EMWG meeting.

Foliar Degradation Data Derivation from Magnitude of Residue Studies - David Jones (and Santhini Ramasamy)

David Jones described a project stimulated by both internal EFED actions and also some data developed on Carbaryl by the registrant.  They did not consider at foliar dislodgeable studies aimed at human exposure.   He made the point that EPA may relax their thinking on using "foreign data" in future where the climate conditions are appropriate to US uses.  David made the point that the presentation actually measures dissipation rather than degradation; and therefore, at some point, it is possible that weather data availability might be added as another data acceptability requirement for a residue dataset.

This approach offers the potential for replacing the aerobic soil default value for foliar degradation.  Can be a very significant term for reducing aquatic exposure assessments - particularly for foliar applied compounds.  The obvious conclusion is that it seems as if the inclusion of a few extra sampling points in a Magnitude of Residue field program is a cheap way of obtaining useful data for some products.

Spatial approaches for designing a statistically-based ecological monitoring program: Lessons learned - Nelson Thurman and Paul Hendley

Joint presentations were made to discuss learning points noted from the work conducted to identify sites for the atrazine ecological monitoring study required by the Jan 31, 2003 IRED.

Questions were asked about the size of selected streams and the planned extent of the monitoring of atrazine use near the selected sampling sites.

Note:  Due to the size of the powerpoint presentation files, anyone interests in getting a copy should contact the presenters.

A degree day concept for estimating degradation time under Field Conditions - Scott Jackson

Measurement of accumulated heat is known as physiological time.  The underlying concept is that since the heat unit approach works well for insects and crops, it therefore should work for the soil organisms that degrade agricultural chemicals.  Due to non-availability of max and min soil and air temperatures (average may be all that is available in some regions), the authors had to generate models based on mean temperature values.  They also added an empirical volumetric water content correction t improve water content depletion.

A question was asked about whether the day length was critical - Answer - No.  But unless photosynthesis provides enough energy (and this is dependent on day length), the system may fail.

The publication described in Scott's presentation is available in full in Pesticide Management Science, Vol. 59, 10 Oct 2003.
