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 all GEAC H75–100, H75–200, 

H80, H80–100, H80–200, H85–100, and 

H85–200 model turboprop engines. The 

NPRM published in the Federal 

Register on October 24, 2022 (87 FR 

64175). The NPRM was prompted by 

AD 2022–0008, dated January 19, 2022, 

issued by the European Union Aviation 

Safety Agency (EASA), which is the 

Technical Agent for the Member States 

of the European Union (referred to after 

this as the MCAI). The MCAI states that 

the airworthiness limitations for H 

series engine models, which are 

approved by EASA, are currently 

defined and published in the ALS of the 

GEAC EMM. These instructions have 

been identified as mandatory for 

continued airworthiness. Failure to 

accomplish these instructions could 

result in an unsafe condition. The MCAI 

explains that recently GEAC published 

a revision to the ALS, introducing 

updated coefficients for the calculation 

of the cyclic life and safe life for the 

main shaft. 

In the NPRM, the FAA proposed to 

require revising the ALS of the existing 

EMM and the operator’s existing 

approved maintenance or inspection 

program, as applicable, to incorporate 

the updated coefficients and recalculate 

the cycles accumulated on critical parts. 

An owner/operator (pilot) holding at 

least a private pilot certificate may 

revise the ALS of the existing EMM, and 

the owner/operator must enter 

compliance with the applicable 

paragraphs of the AD into the aircraft 

records in showing compliance with 

this AD in accordance with 14 CFR 

43.9(a) and 14 CFR 91.417(a)(2)(v). The 

record must be maintained as required 

by 14 CFR 91.417, 121.380, or 135.439. 

This is an exception to the FAA’s 

standard maintenance regulations. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2022–1302. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Conclusion 

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 referenced 

above. The FAA reviewed the relevant 

data and determined that air safety 

requires adopting this AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. Except for minor editorial 

changes, this AD is adopted as proposed 

in the NPRM. 

Related Service Information 

The FAA reviewed the ALS of the 

GEAC EMM, Part No: 0983402, Rev. 22, 

dated December 18, 2020. This service 

information provides updated 

coefficients for the calculation of the 

cyclic life and safe life for the main 

shaft. 

Costs of Compliance 

The FAA estimates that this AD 

affects 33 engines installed on airplanes 

of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

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 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.
