SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain serial-numbered
Piaggio Model P-180 airplanes. The NPRM published in the Federal
Register on April 8, 2022 (87 FR 20790). The NPRM was prompted by MCAI
originated by the European Union Aviation Safety Agency (EASA), which
is the Technical Agent for the Member States of the European Union.
EASA issued EASA AD 2019-0269, dated October 29, 2019 (referred to
after this as ``the MCAI''), to address the unsafe condition on Piaggio
Model P.180 Avanti II airplanes. The MCAI states:
During monitoring of P.180 Avanti II fleet by EUROCONTROL
(checks performed by Air Traffic Control stations) a mean altimetry
system error and some singular measurement exceedances were reported
being outside of limits defined by rules applicable to Reduced
Vertical Separation Minimum (RVSM) airworthiness standards.
Subsequent investigation determined that the static source error
correction curves embedded in the ADC of pilot and co-pilot, as well
as in the stand-by instrument system, did not ensure the required
RVSM performance of the aeroplane.
This condition, if not corrected, could lead to delivery [of]
erroneous air data information and consequent impairment of
aeroplane altitude-keeping capability, possibly resulting in a mid-
air collision within RVSM airspace.
To address this potential unsafe condition, Piaggio issued the
AFM TC [Temporary
[[Page 54359]]
Change No. 107] introducing additional limitations for operation
within RVSM airspace and issued the SB [Piaggio Aerospace Service
Bulletin 80-0467] providing instructions to modify the aeroplane.
For the reasons described above, this [EASA] AD requires
amendment of the AFM and modification of the aeroplane by installing
improved ADCs and DCM.
You may examine the MCAI in the AD docket at <a href="http://www.regulations.gov">www.regulations.gov</a> by
searching for and locating Docket No. FAA-2022-0397.
In the NPRM, the FAA proposed to require amending the existing AFM,
installing improved ADCs and a DCM, and revising the existing
instructions for continued airworthiness. The FAA is issuing this AD to
prevent a mean altimetry system error measurement from exceeding the
limits defined for operations within airspace designed as RVSM
airspace. The unsafe condition, if not addressed, could result in a
potential mid-air collision within RVSM airspace.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from Piaggio. The following presents the
comment received on the NPRM and the FAA's response to the comment.
Request To Update Obsolete Contact Information for Piaggio
Piaggio requested that the FAA revise the NPRM to update their
contact information for service information.
The FAA agrees and has updated the contact information for Piaggio
accordingly.
Conclusion
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI and
service information referenced above. The FAA reviewed the relevant
data, considered the comment received, and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on this product. Except for the
changes described previously, this AD is adopted as proposed in the
NPRM. None of the changes will increase the economic burden on any
operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Piaggio Aero Industries S.p.A. A.S. Service
Bulletin No. 80-0467, Revision 2, dated March 6, 2020, which specifies
procedures for replacing the two ADCs and the DCM with improved parts.
The FAA also reviewed Piaggio Aviation P.180 Avanti II/EVO
Temporary Change No. 107, dated September 17, 2019, which updates the
limitations section of the AFM by prohibiting operations in RVSM
airspace if the ADCs and DCM have not been replaced.
In addition, the FAA reviewed Piaggio Aviation P.180 Avanti EVO
Maintenance Manual Temporary Revision No. 126, dated June 6, 2019,
which updates and adds certain tasks for the navigation system.
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.
Differences Between This AD and the MCAI
The MCAI requires informing all flight crews of the AFM revision
and operating accordingly thereafter, and this AD does not because
those actions are already required by FAA operating regulations.
Costs of Compliance
The FAA estimates that this AD will affect 101 airplanes of U.S.
registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost airplane operators
----------------------------------------------------------------------------------------------------------------
Revise AFM...................... 1 work-hour x $85 Not Applicable........... $85 $8,585
per hour = $85.
Update AFM...................... 1 work-hour x $85 Not Applicable........... 85 8,585
per hour = $85.
Replace two ADCs and one DCM.... 16 work-hours x $85 $21,900.................. 23,260 2,349,260
per hour = $1,360.
----------------------------------------------------------------------------------------------------------------
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 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.
