SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0013, dated January 13, 2021
(EASA AD 2021-0013) (also referred to as the MCAI), to correct an
unsafe condition for all ATR-GIE Avions de Transport R[eacute]gional
Model ATR42-500 and ATR72-212A airplanes.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all ATR-GIE Avions de
Transport R[eacute]gional Model ATR42-500 and ATR72-212A airplanes. The
NPRM published in the Federal Register on July 7, 2021 (86 FR 35697).
The NPRM was prompted by reports indicating that Thales GPS SBAS
receivers provided, under certain conditions, erroneous outputs on
aircraft positions. The NPRM proposed to require replacing affected GPS
SBAS receivers with new, improved receivers, as specified in EASA AD
2021-0013.
The FAA is issuing this AD to address erroneous aircraft position
outputs from the GPS SBAS receivers, which could result in controlled
flight into terrain, and consequent loss of control of the airplane.
See the MCAI for additional background information.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from the Air Line Pilots Association,
International, (ALPA) who supported the NPRM without change.
Conclusion
The FAA reviewed the relevant data and determined that air safety
requires adopting this AD as proposed. Except for minor editorial
changes, this AD is adopted as proposed in the NPRM. None of the
changes will increase the economic burden on any operator. Accordingly,
the FAA is issuing this AD to address the unsafe condition on these
products.
Related AD
AD 2020-08-02, Amendment 39-21108 (85 FR 20586, April 14, 2020) (AD
2020-08-02) applies to certain Thales GPS SBAS receivers installed on
airplanes (including Model ATR42-500 and ATR72-212A) and helicopters.
AD 2020-08-02 requires the installation of a software update to the
aircraft navigation database and insertion of a change to the
applicable airplane flight manual (AFM). The FAA issued AD 2020-08-02
to address erroneous aircraft position outputs from the affected Thales
GPS SBAS receivers, which could result in controlled flight into
terrain and loss of the aircraft. AD 2020-08-02 corresponds to EASA AD
2019-0004, dated January 11, 2019. Upon completion of EASA AD 2021-0013
by Model ATR42-500 and ATR72-212A airplanes, all requirements of EASA
AD 2019-0004 are effectively terminated for those airplanes.
Related Service Information Under 1 CFR Part 51
EASA AD 2021-0013 describes procedures for replacing certain GPS
SBAS receivers with new, improved receivers. This material 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.
Costs of Compliance
The FAA estimates that this AD affects 15 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170........................... $0 * $170 $2,550
----------------------------------------------------------------------------------------------------------------
The manufacturer will provide replacement receivers at no cost to the operators. The FAA has received no
definitive data on which to base the cost estimates for these parts.
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
This AD will not have federalism implications under Executive Order
13132. This AD will not have a
[[Page 54803]]
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.
