2019-14-11 DIAMOND AIRCRAFT INDUSTRIES GMBH: Amendment 39-19689; Docket No. FAA-2019-0203; Product Identifier 2018-CE-052-AD.
(a) EFFECTIVE DATE

    This AD is effective September 9, 2019.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This AD applies to Diamond Aircraft Industries GmbH (Diamond) Model DA
    42 NG and Model DA 42 M-NG airplanes, serial numbers 42.N202, 42.N203,
    42.N205  through  42.N207, 42.N210  through  42.N214, 42.N229  through
    42.N338, 42.N340,  42.MN055, 42.MN057,  and 42.MN058,  certificated in
    any category.

(d) SUBJECT

    Air Transport Association of America (ATA) Code 27: Flight Controls.

(e) REASON

    This AD was prompted by mandatory continuing airworthiness information
    (MCAI)  originated  by an  aviation  authority of  another  country to
    identify and correct an unsafe  condition on an aviation product.  The
    unsafe condition reported by the MCAI is insufficient clearance of the
    gust lock mounts on the pilot  side rudder pedals. The FAA is  issuing
    this AD  to prevent  restricted rudder  travel, which  could result in
    reduced control of the airplane.

(f) ACTIONS AND COMPLIANCE

    Unless already done, do the following actions in paragraphs (f)(1) and
    (2) of this AD.

(1) Within the next 100 hours time-in-service after September 9, 2019 (the
    effective date of this AD):

(i) Remove  the  pilot  (left-hand) side rudder pedal gust lock mounts  in
    accordance  with steps 1 through 5 of the Instructions in Diamond Air-
    craft Industries GmbH Work Instruction WI-MSB 42NG-077,  dated  August
    20, 2018.

(ii) Revise the airplane flight manual (AFM) by adding the figures on page
     8-11a of Diamond Aircraft Temporary Revision  TR-MAM 42-1097 Gustlock
     on Co-Pilot Side only,  Doc. #7.01.15-E,  dated  July 18, 2018,  into
     Chapter 8 of the AFM.

(2) As  of  September 9, 2019 (the effective date of this AD),  do not in-
    stall on any airplane a pilot (left-hand) side rudder pedal  gust lock
    mount.

(g) ALTERNATIVE METHODS OF COMPLIANCE (AMOCS)

    The Manager, Small Airplane Standards Branch,  FAA,  has the authority
    to approve AMOCs for this AD,  if requested using the procedures found
    in 14 CFR 39.19.  Send information  to  ATTN:  Mike Kiesov,  Aerospace
    Engineer,  FAA, Small Airplane Standards Branch, 901 Locust, Room 301,

    -4090;  email: mike.kiesov@faa.gov.  Before using any approved AMOC on
    any airplane to which the AMOC applies,  notify your appropriate prin-
    cipal  inspector  (PI)  in  the  FAA  Flight Standards District Office
    (FSDO), or lacking a PI, your local FSDO.

SUPPLEMENTARY INFORMATION:

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Diamond
Aircraft Industries GmbH Model DA 42 NG and Model DA 42 M-NG airplanes.
The NPRM published in the Federal Register on April 2, 2019 (84 FR
12532). The NPRM proposed to require removing the left-hand pilot
rudder pedal gust lock mounts and revising the airplane flight manual.
The NPRM was based on MCAI originated by the European Aviation Safety
Agency (EASA), which is the Technical Agent for the Member States of
the European Community. The MCAI states:

During production check-out of two DA 42 NG aeroplanes, it was
noticed that, with the adjustable rudder pedals in full forward
position, the gust lock mounts slightly touched the canopy gas
spring damper. The subsequent investigation found that this was due
to an unfavourable combination of production tolerances on these two
aeroplanes. [Diamond Aircraft Industries GmbH] DAI determined that
other aeroplanes of the same build standard (configuration) may also
be affected.
This condition, if not corrected, could lead to restricted
rudder travel, possibly resulting in reduced control of the
aeroplane.
Prompted by these findings, DAI published the [mandatory service
bulletin] MSB, providing modification instructions to remove the
gust lock mounts on the pilot (left-hand, LH) side rudder pedals to
ensure sufficient clearance, regardless of production tolerances and
rudder pedal position.
For the reason described above, this [EASA] AD requires
implementation of a temporary revision (TR) to the applicable
Airplane Flight Manual (AFM) and a modification, removing the pilot
(LH) side rudder pedal gust lock mounts.

The MCAI can be found in the AD docket on the internet at https://www.regulations.gov/document?D=FAA-2019-0203-0002.

Comments

The FAA gave the public the opportunity to participate in
developing this final rule. The FAA received no comments on the NPRM or
on the determination of the cost to the public.

Conclusion

The FAA reviewed the relevant data and determined that air safety
and the public interest require adopting this final rule as proposed.

Related Service Information Under 1 CFR Part 51

The FAA reviewed Diamond Aircraft Temporary Revision TR-M[Auml]M
42-1097 Gustlock on Co-Pilot Side only, Doc. #7.01.15-E, dated July 18,
2018 (TR-MAM 42-1097), which contains amended figures related to the
gust lock belt. The FAA also reviewed Diamond Aircraft Industries GmbH
Work Instruction WI-MSB 42NG-077, dated August 20, 2018, which contains
procedures for removing the pilot (LH) side rudder pedal gust lock
mounts and specifies inserting a copy of TR-MAM 42-1097 into the AFM.
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

The FAA also reviewed Diamond Mandatory Service Bulletin MSB 42NG-
077, dated August 20, 2018, which specifies complying with the most
recent issue of Work Instruction WI-MSB 42NG-077.

Costs of Compliance

The FAA estimates that this AD will affect 53 products of U.S.
registry. The FAA also estimates that it will take about 1 work-hour
per product to comply with the removal of the pilot side rudder pedal
gust lock mounts and to insert copy of TR-MAM 42-1097 into the AFM. The
average labor rate is $85 per work-hour. Required parts will cost about
$10 per product.
Based on these figures, the FAA estimates the cost of this AD on
U.S. operators to be $5,035, or $95 per product.

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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to small airplanes, gliders,
balloons, airships, domestic business jet transport airplanes, and
associated appliances to the Director of the Policy and Innovation
Division.

Regulatory Findings

The FAA 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 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.
