reports of an oil leak from the main 

gearbox (MGB) during engine start up. 

This AD requires modifying and 

performing subsequent repetitive 

function testing of the MGB emergency 

lubrication (EMLUB) system as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

incorporated by reference (IBR). The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective July 12, 

2021. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2016–0232, 

dated November 22, 2016 (EASA AD 

2016–0232), to correct an unsafe 

condition for Airbus Helicopters Model 

EC 225 LP helicopters. EASA later 

issued EASA AD 2016–0232R1, dated 

December 12, 2019 (EASA AD 2016– 

0232R1), to revise EASA AD 2016–0232. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Airbus Helicopters Model 

EC225LP helicopters. The NPRM 

published in the Federal Register on 

March 15, 2021 (86 FR 14281). The 

NPRM was prompted by reports of oil 

leaks during engine starting, originating 

from the MGB. The NPRM proposed to 

require modifying and repetitively 

functional testing the MGB EMLUB 

system, and if there is a discrepancy, 

accomplishing corrective action(s). 

Accomplishing any corrective action(s) 

does not constitute terminating action 

for the repetitive functional tests, as 

specified in an EASA AD. 

The FAA is issuing this AD to address 

inadvertent opening of the P 2.4 valve 

of the MGB EMLUB system, which 

results from MGB pressurization by 

compressed air produced by the engine 

during starting in response to a signal 

from the EMLUB electronic control 

card. See EASA AD 2016–0232R1 for 

additional background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The FAA received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Conclusion 

The FAA reviewed the relevant data 

and determined that air safety and the 

public interest require adopting this 

final rule as proposed, except for minor 

editorial changes. The FAA has 

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 

EASA AD 2016–0232R1 requires 

modifying the electrical control circuit 

of the MGB EMLUB system. After 

modifying, EASA AD 2016–0232R1 

requires a repetitive functional test of 

the MGB EMLUB system, and if there is 

a discrepancy, accomplishing corrective 

action(s). Accomplishing any corrective 

action(s) does not constitute terminating 

action for the repetitive functional tests. 

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. 

Differences Between This AD and the 

EASA AD 

Where EASA AD 2016–0232R1 refers 

to December 6, 2016 (the effective date 

of EASA AD 2016–0232), this AD 

requires using the effective date of this 

final rule. EASA AD 2016–0232R1 

allows an additional interval margin of 

225 flight hours (FH), while this AD 

does not. Where the service information 

referenced in EASA AD 2016–0232R1 

requires contacting Airbus Helicopters 

for corrective action, this AD requires 

accomplishing the corrective action 

using a method approved by the 


khammond on DSKJM1Z7X2PROD with RULES
30152 Federal Register / Vol. 86, No. 107 / Monday, June 7, 2021 / Rules and Regulations 

Manager, Strategic Policy Rotorcraft 

Section, FAA. 

Costs of Compliance 

The FAA estimates that this AD 

affects 24 helicopters of U.S. Registry. 

Labor rates are estimated at $85 per 

work-hour. Based on these numbers, the 

FAA estimates that operators may incur 

the following costs in order to comply 

with this AD. 

Modifying the electrical control 

circuit of the MGB EMLUB system takes 

about 22 work-hours and parts cost 

about $1,592 for an estimated cost of 

$3,462 per helicopter and $83,088 for 

the U.S. fleet. 

Functional testing the EMLUB system 

takes about 12 work-hours for an 

estimated cost of $1,020 per helicopter 

and $24,480 for U.S. fleet, per testing 

cycle. If the electrical functional test 

results in a need to replace the 

lubrication printed circuit board, the 

replacement time takes about 2 workhours and parts cost about $5,150 for an 

estimated cost of $5,320 per helicopter. 

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.

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0095, 

dated March 31, 2021 (EASA AD 2021– 

0095), to correct an unsafe condition for 

Leonardo S.p.a. Model AB139 and 

AW139 helicopters with 3-stretcher kit 

part number 139084–501 installed by a 

certain supplemental type certificate 

(STC). EASA advises that a design 

deficiency was identified, affecting the 

primary stretcher unit, part number 

002095–502, of the 3-stretcher kit part 

number 139084–501. This condition, if 

not addressed, could lead, in case of an 

emergency landing, to failure of the 

primary stretcher of the 3-stretcher kit, 

possibly resulting in injury to helicopter 

occupants. 

Accordingly, EASA AD 2021–0095 

requires installing a placard on the 

primary stretcher stating a limitation of 

61 kg (134.5 lbs) for the maximum 

allowable weight of the occupant on the 

primary stretcher. EASA considers its 

AD an interim action and states that 

further AD action may follow. Although 

EASA AD 2021–0095 applies to 

Leonardo S.p.a. Model AB139 and 

AW139 helicopters with 3-stretcher kit 

part number 139084–501 installed by a 

certain STC, this AD applies to 

helicopters with an affected part 

installed instead. 

FAA’s Determination 

These helicopters have been approved 

by EASA and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the 

European Union, EASA has notified the 

FAA about the unsafe condition 

described in its AD. The FAA is issuing 

this AD after evaluating all known 

relevant information and determining 

that the unsafe condition described 

previously is likely to exist or develop 

on other helicopters of these same type 

designs. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Aerolite Alert 

Service Bulletin ASB–21–006, dated 

March 16, 2021. This service 

information specifies procedures for 

installing a weight limit placard on the 

primary stretcher unit of the 3-stretcher 

kit. 

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. 

AD Requirements 

This AD requires accomplishing the 

actions specified in the service 

information already described, except as 

discussed under ‘‘Differences Between 

the AD and the EASA AD.’’
