Airworthiness Directives; Various 

Aircraft Equipped With BRPPowertrain GmbH & Co KG 912 A 

Series Engine 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for various 

aircraft equipped with a BRP-Powertrain 

GmbH & Co KG (formerly Rotax Aircraft 

Engines) 912 A series engine. This 

proposed AD results from mandatory 

continuing airworthiness information 

(MCAI) originated by an aviation 

authority of another country to identify 

and correct an unsafe condition on an 

aviation product. The MCAI describes 

the unsafe condition as a design change 

of the engine cylinder head temperature 

sensor without a concurrent revision of 

the engine model designation, the 

engine part number, or the cockpit 

indication to the pilot. We are issuing 

this proposed AD to require actions to 

address the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by May 12, 2016. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No.: 2015– 

0240, dated December 18, 2015, to 

correct an unsafe condition for the 

specified products. The MCAI states: 

A design change of the engine cylinder 

heads was introduced by BRP-Powertrain in 

March 2013 which modifies the engine/

aircraft interfaces by substituting the 


Lhorne on DSK5TPTVN1PROD with PROPOSALS
17110 Federal Register / Vol. 81, No. 59 / Monday, March 28, 2016 / Proposed Rules 

previous cylinder head temperature (CHT) 

measurement (limit temperature 135 °C/150 

°C) with a coolant temperature (CT) 

measurement (limit temperature 120 °C). The 

design change was communicated on 15 May 

2013 by BRP-Powertrain Service Instruction 

(SI) 912–020R7/914–022R7 (single 

document) but was not identified by a change 

of the engine model designation or of the 

engine P/N, but only through the cylinder 

head P/N and the position of the temperature 

sensor. 

Consequently, engines with the new 

cylinder heads (installed during production 

or replaced in-service during maintenance) 

may be installed on an aircraft without 

concurrent modification of that aircraft, 

instructions for which should be provided by 

the Type Certificate (TC) holder or 

Supplemental Type Certificate (STC) holder, 

as applicable. In this case, the coolant 

temperature with a maximum engine 

operating limit of 120 °C (valid for engines 

operated with water diluted glycol coolant) is 

displayed on a CHT indicator with a typical 

limit marking (red radial/range) of more than 

120 °C. 

This condition, if not detected and 

corrected, will prevent the pilot to identify 

coolant limit exceedances, with subsequent 

loss of coolant (120 °C is the boiling 

temperature of the coolant), which could lead 

to engine in-flight shut-down, possibly 

resulting in a forced landing, with 

consequent damage to the aircraft and injury 

to occupants. 

BRP-Powertrain published revised SI–912– 

020R8/914–022R8 to clarify that, on the new 

cylinder heads, the coolant temperature, 

instead of the cylinder head temperature in 

the aluminium, is measured. EASA issued 

SIB 2014–34 to raise awareness that 

installation of affected engines and spare 

parts, without concurrent incorporation of 

aircraft TC/STC holder approved 

modifications, and even if unintended and 

unnoticed by production or maintenance, 

constitutes an unapproved aircraft 

modification. 

Since EASA published the SIB, further 

investigation has finally determined that 

sufficient reason exists to warrant AD action. 

For the reason stated above, this AD 

requires a one-time inspection to determine 

the actual engine configuration and, 

depending on findings, engine 

reidentification and (depending on TC or 

STC holder installation) modification of the 

affected aircraft. This also affects engines that 

are operated with waterless coolant.

Internet at http://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2016–4878. 

Related Service Information Under 1 

CFR Part 51 

BRP-Powertrain GmbH & CO KG has 

issued Rotax Aircraft Engines BRP 

Service Bulletin SB–912–068 and SB– 

914–049 (co-published as one 

document), dated April 16, 2015. The 

service information describes 

procedures for re-identifying the engine 

that has new cylinder heads, part 

numbers 413235 and 413236 installed. 

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 NPRM. 

FAA’s Determination and Requirements 

of the Proposed 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 proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 65 products of U.S. 

registry. 

We also estimate that it would take 

about 1 work-hour per product to 

comply with the engine re-identification 

requirement of this proposed AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of this portion of this proposed 

AD on U.S. operators to be $5,525, or 

$85 per product. 

We also estimate that it would take 

about 1 work-hour per product to 

comply with the engine installation 

modification to indicate a Maximum 

Coolant Temperature requirement of 

this proposed AD. The average labor 

rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of this portion of this proposed 

AD on U.S. operators to be $5,525, or 

$85 per product. 

We also estimate that it would take 

about 1.5 work-hours per product to 

comply with the cylinder head 

replacement option of this proposed 

AD. The average labor rate is $85 per 

work-hour. Required parts would cost 

about $2,500 to replace a single engine 

cylinder head. 

Based on these figures, we estimate 

the cost of this portion of this proposed 

AD on U.S. operators to be $2,627.50 

per engine cylinder head. 

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. 

Regulatory Findings 

We 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) 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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD:

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all serial numbers of the 

airplanes listed in table 1 of paragraph (c) of 

this AD, that are: 

(1) Equipped with a BRP-Powertrain GmbH 

& Co KG (formerly Rotax Aircraft Engines) 

912 A series engine with a part number (P/ 

N) 413235 or 413236 cylinder head installed

(d) Subject 

Air Transport Association of America 

(ATA) Code 72: Engine—Reciprocating. 

(e) Reason 

This AD was prompted by design change 

of the engine cylinder head temperature 

sensor without a concurrent revision of the 

engine model designation, the engine part 

number, or the cockpit indication to the 

pilot. The sensor now measures the coolant 

temperature rather than the cylinder head 

temperature. If the engine coolant 

temperature with a maximum engine 

operating limit of 120 °C is displayed on a 

Cylinder Head Temperature indicator with a 

typical limit marking greater than 120 °C, the 

pilot will be unable to identify coolant 

temperature limit exceedances. This could 

result in loss of coolant, which could cause 

an inflight engine shutdown and forced 

landing. 

(f) Actions and Compliance 

Unless already done, do the following 

actions: 

(1) Within 6 months after the effective date 

of this AD, for engines with cylinder heads 

listed in paragraph (c)(1) of this AD installed 

on both position 2 and position 3, change the 

engine model designation on the engine type 

data plate to include a ‘‘–01’’ suffix following 

paragraph 3.1.1) of the Accomplishment/

Instructions in Rotax Aircraft Engines BRP 

Service Bulletin SB–912–068 and SB–914– 

049 (co-published as one document), dated 

April 16, 2015. 

(2) Within 6 months after the effective date 

of this AD, for engines with only one 

cylinder head listed paragraph (c)(1) of this 

AD installed in a position 2 or 3, in order to 

keep such cylinder installed, you must 

replace the cylinder head installed on the 

unchanged position (2 or 3, as applicable) 

with a cylinder head having a P/N listed in 

paragraph (c)(1) of this AD, and change the 

engine model designation on the engine type 

data plate to include a ‘‘–01’’ suffix following 

paragraph 3.1.1) of the Accomplishment/

Instructions in Rotax Aircraft Engines BRP 

Service Bulletin SB–912–068 and SB–914– 

049 (co-published as one document), dated 

April 16, 2015. 

(3) Before further flight after doing the 

required actions in paragraphs (f)(1) or (f)(2) 

of this AD as applicable, modify the aircraft 

and related documentation to indicate a 

Maximum Coolant Temperature limit of 120 

°C using FAA-approved procedures. 

(i) Such procedures can be found by 

contacting your aircraft type certificate 

holder or the FAA contact specified in 

paragraph (g)(1) of this AD. The service 

documents referenced in paragraph (h) of this 

AD are examples of FAA-approved 

procedures for the applicable aircraft. 

(ii) These re-identified engines remain 

eligible for installation on approved aircraftengine combinations. 

(4) As of the effective date of this AD, do 

not install any other P/N cylinder head 

unless that installation is done following 

approved instructions provided by BRPPowertrain at the address provided in 

paragraph (h) of this AD. 

(g) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Standards Office, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures

4090; email: jim.rutherford@faa.gov. Before 

using any approved AMOC on any airplane 

to which the AMOC applies, notify your 

appropriate principal inspector (PI) in the 

FAA Flight Standards District Office (FSDO), 

or lacking a PI, your local FSDO. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service.
