Airworthiness Directives; Polskie Zaklady Lotnicze Sp. z o.o. Airplanes
AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Notice of proposed rulemaking (NPRM).
SUMMARY:
The FAA proposes to adopt a new airworthiness directive (AD) for all Polskie Zaklady Lotnicze Sp. z o.o. Model PZL M28 05 airplanes. This proposed AD was prompted by incorrect flap settings and airspeed during approach for landing under one engine inoperative (OEI) conditions in the airplane flight manual (AFM) emergency procedures. This proposed AD would require revising the existing AFM for your airplane to provide the correct emergency procedures. The FAA is proposing this AD to address the unsafe condition on these products.
DATES:
The FAA must receive comments on this NPRM by August 7, 2025.

Confidential Business Information
CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this NPRM contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this NPRM, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as "PROPIN." The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this NPRM. Submissions containing CBI should be sent to Doug Rudolph, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking.
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 Zaklady 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 Lolnicze 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 Zaklady 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.
[top] 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
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:
| Action | Labor cost | Parts cost | Cost per product | Cost on U.S. operators |
|---|---|---|---|---|
| Revise AFM and checklist | 2 work-hours × $85 per hour = $170 | $0 | $170 | $1,530 |
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.
