Aircraft Equipped With BRP-Rotax GmbH & Co KG 912 A Series Engine 
AGENCY : Federal Aviation 
Administration (FAA), Department of Transportation (DOT). 
ACTION : Final rule. 
SUMMARY : We are adopting a new 
airworthiness directive (AD) for various aircraft equipped with a BRP-Rotax GmbH & Co. KG (formerly BRP- Powertrain GmbH & Co. KG; Bombardier-Rotax GmbH & Co. KG; Bombardier-Rotax GmbH) 912 A series engine. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as defective valve push-rod assemblies manufactured from June 8, 2016, through October 2, 2017. We are issuing this AD to require actions to address the unsafe condition on these products. 
DATES : This AD is effective March 20, 
2018. 
The Director of the Federal Register 
approved the incorporation by reference of a certain publication listed in this AD as of March 20, 2018.

SUPPLEMENTARY INFORMATION : 
Discussion 
We issued a notice of proposed 
rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to various aircraft equipped with a BRP-Rotax GmbH & Co. KG (formerly BRP-Powertrain GmbH & Co. KG; Bombardier-Rotax GmbH & Co. KG; Bombardier-Rotax GmbH) 912 A series engine. The NPRM was published in the Federal Register on November 22, 2017 (82 FR 55527). The NPRM proposed to address an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. 
The MCAI states: 
Power loss and engine RPM drop have 
been reported on Rotax 912/914 engines in 
service. It has been determined that, due to a quality control deficiency in the manufacturing process of certain valve push- rod assemblies, manufactured between 08 June 2016 and 02 October 2017 inclusive, partial wear on the rocker arm ball socket may occur, which may lead to malfunction of the valve train. 
This condition, if not detected and 
corrected, may lead to rough engine operation and loss of power, possibly resulting in a forced landing, with consequent damage to the aeroplane and injury to occupants. 
To address this potential unsafe condition, 
BRP-Rotax issued Service Bulletin (SB) SB– 912 i–008/SB–912–070/SB–914–052 (single document), providing applicable instructions. 
For the reason described above, this 
[EASA] AD requires a one-time inspection and, depending on findings, replacement of affected parts. This [EASA] AD also prohibits installation of affected parts on an engine]. 
The MCAI can be found in the AD 
docket on the internet at https://
www.regulations.gov/ document?D=FAA-2017-1078-0002. 
Comments 
We gave the public the opportunity to 
participate in developing this AD. We 
received no comments on the NPRM or on the determination of the cost to the public. 
Conclusion 
We reviewed the relevant data and 
determined that air safety and the 
public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes: 
•Are consistent with the intent that 
was proposed in the NPRM for addressing the unsafe condition; and 
•Do not add any additional burden 
upon the public than was already proposed in the NPRM. 
Related Service Information Under 1 
CFR Part 51 
We reviewed BRP-Rotax GmbH & Co 
KG Rotax Aircraft Engines BRP Service Bulletin SB–912 i–008 R1/SB–912–070 R1/SB–914–052 R1 (co-published as one document), Revision 1, dated October 12, 2017. The service information describes procedures for inspecting and, if necessary, replacing the valve push- rod assembly on the left and/or right rocker arms. 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 of this AD. 
Costs of Compliance 
We estimate that this AD will affect 
63 products of U.S. registry. We also estimate that it will take about 1 work- hour per product to comply with the basic inspection requirement of this AD. The average labor rate is $85 per work- hour. Required parts will cost about $70 per product. 
Based on these figures, we estimate 
the cost of this AD on U.S. operators to be $9,765, or $155 per product.

In addition, we estimate that any 
necessary follow-on actions will take 
about 2 work-hours to replace all 8 valve push-rod assemblies and associated parts on all 4 cylinders and require parts costing $3,093, for a cost of $3,263 per product. We have no way of determining the number of products that may need these actions. 
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. 
We are 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. 
This AD is issued in accordance with 
authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to small airplanes, gliders, balloons, airships, domestic business jet transport airplanes, and associated 
appliances to the Director of the Policy and Innovation Division. Regulatory Findings 
We determined that 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) Is not a ‘‘significant rule’’ under 
the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), 
(3) Will not affect intrastate aviation 
in Alaska, and 
(4) 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.

SUPPLEMENTARY INFORMATION : 
Discussion 
The Civil Aviation Authority, which 
is the aviation authority for New Zealand, has issued CAA AD DCA/ 750XL/22, dated December 19, 2017 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for Pacific Aerospace Limited Model 750XL airplanes. To accompany that MCAI, the CAA issued Notification of Airworthiness Directive issued for New Zealand Aeronautical Products IAW ICAO Annex 8, dated December 19, 2017; the Notification states: 
This [CAA] AD with effective date 28 
December 2017 mandates an inspection of 
components and wiring behind the instrument panel for possible abrasion damage caused by ventilation hose chafing per the instructions in Pacific Aerospace Mandatory Service Bulletin (MSB) PACSB/ XL/083 issue 1, dated 15 December 2017, or later approved revision. 
The [CAA] AD is prompted by two reports 
of finding abrasion damage behind the instrument panel caused by ventilation hose chafing. 
In addition to the required inspection, 
this AD requires wrapping the 
ventilation hose with anti-abrasion tape and rerouting the hose. This AD also requires contacting the manufacturer for corrective action if abrasion damage is found during the required inspection. You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2018–0067. 
Related Service Information Under 1 
CFR Part 51 
Pacific Aerospace Limited has issued 
Pacific Aerospace Mandatory Service Bulletin PACSB/XL/083, Issue 1, dated December 15, 2017. The service information describes procedures for inspection of the ventilation hose behind the instrument panel, wrapping the ventilation hose with anti-abrasion tape, and rerouting the hose. 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 of 
the AD. 
FAA’s Determination and Requirements 
of the AD 
This product has been approved by 
the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. 
FAA’s Determination of the Effective 
Date 
An unsafe condition exists that 
requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because chafing of the ventilation hose on instrument components and wiring could cause abrasion damage and lead to short circuit, smoke, and/or fire. Therefore, we determined that notice
