Background

    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2024-0183, dated September 20, 2024 (EASA AD 2024-0183) (also 
referred to as ``the MCAI''), to correct an unsafe condition on Polskie 
Zaklady Lotnicze Sp. z o.o. Models PZL M28 02-W and PZL M28 05 
airplanes, all manufacturer serial numbers. The MCAI states that 
occurrences have been reported by pilot instructors where, during type 
rating training with Model PZL M28 airplanes, students applied an 
incorrect flap setting and airspeed while practicing the emergency 
procedure for an approach and landing with OEI after a simulated engine 
failure. The investigation concluded that the root cause for these 
occurrences was typographical errors in the AFM. The MCAI requires 
incorporating an AFM update containing the correct flap setting and 
airspeed to be applied during approach with OEI. Applying an incorrect 
flap setting and airspeed during an approach for landing under 
(simulated) OEI conditions could result in loss of control of the 
airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2025-1113.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed pages 3-4 ENGINE FAILURE AT DESCENT and ENGINE 
FAILURE DURING BALKED LANDING; 3-9 BALKED LANDING WITH ONE ENGINE 
INOPERATIVE; 3-17 ENGINE FAILURE AT DESCENT (LANDING APPROACH); 3-18 
ENGINE FAILURE DURING BALKED LANDING; and 3-25 and 3-26 BALKED LANDING 
WITH ONE ENGINE INOPERATIVE from Section 3, Emergency Procedures in 
Polskie Zak[lstrok]ady Lotnicze Sp. z o.o. Airplane Flight Manual, 
Model PZL M28 05, Revision 55, dated July 9, 2024. This material 
provides the correct emergency procedures for the flightcrew when 
adjusting the flap settings and airspeed during approach for landing 
under simulated OEI conditions.
    The FAA also reviewed Polskie Zaklady Lo[lstrok]nicze Sp. z o.o. 
Check List, PZL M28 05 with PT6A-65B engines, Emergency Procedures, 
Revision 1, dated July 9, 2024. This material provides the flightcrew 
with the correct emergency procedures checklist that corresponds with 
the changes to Section 3, Emergency Procedures, of the AFM.
    In addition, the FAA reviewed Polskie Zak[lstrok]ady Lotnicze Sp. z 
o.o. Check List, PZL M28 05 with PT6A-65B engines, Emergency 
Procedures, effective on airplanes without the installed ice protection 
system certified for flights in known and forecast icing conditions, 
Revision 1, dated July 9, 2024. This material provides the flightcrew 
with the correct emergency procedures checklist that corresponds with 
the changes to Section 3, Emergency Procedures, of the AFM.
    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.

FAA's Determination

    These products have been approved by the aviation authority of 
another country and are 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 material referenced above. The FAA is issuing this NPRM 
after determining that the unsafe condition described previously is 
likely to exist or develop on other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require revising the existing AFM for your 
airplane to provide the correct emergency procedures and checklist for 
the flightcrew when adjusting the flap settings and airspeed during 
approach for landing under OEI conditions. See ``Differences Between 
this Proposed AD and the MCAI'' for a discussion of the general 
differences included in this AD.
    The owner/operator (pilot) holding at least a private pilot 
certificate may revise the existing AFM and checklist for your airplane 
and must enter compliance with the applicable paragraph of this 
proposed AD into the airplane maintenance records in

[[Page 26465]]

accordance with 14 CFR 43.9(a) and 91.417(a)(2)(v). The pilot may 
perform this action because it only involves revising the AFM. This 
action could be performed equally well by a pilot or a mechanic. This 
is an exception to the FAA's standard maintenance regulations.

Differences Between This Proposed AD and the MCAI

    The MCAI applies to Polskie Zaklady Lotnicze Sp. z o.o. Model PZL 
M28 02-W airplanes, but this proposed AD would not because this model 
does not have an FAA type certificate.
    The MCAI requires informing all pilots about the AFM update and 
thereafter operating the airplane accordingly, and this proposed AD 
would not because those actions are already required by FAA 
regulations.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect nine airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

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 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
