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 certain Bombardier, Inc., Model 

CL–600–2B16 (CL–601–3A, CL–601–3R, 

and CL–604 Variants) airplanes. The 

NPRM published in the Federal 

Register on May 22, 2017 (82 FR 23156) 

(‘‘the NPRM’’). The NPRM was 

prompted by a report indicating that the 

lanyard length of the passenger drop 

down oxygen masks is too long. The 

NPRM proposed to require replacing the 

existing oxygen mask lanyards with 

lanyards of the correct length. We are 

issuing this AD to prevent improper 

oxygen flow functionality to the 

passenger oxygen masks in the event of 

an emergency. 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2016–15, 

dated May 18, 2016 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ’’the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc., Model CL– 

600–2B16 (CL–601–3A, CL–601–3R, and 

CL–604 Variants) airplanes. The MCAI 

states: 

Bombardier (BA) has determined that the 

lanyard length of the passenger drop down 

oxygen masks is too long and may cause the 

safety pin tethered to the opposite end of the 

lanyard to remain engaged in the oxygen flow 

mechanism when the mask is pulled to the 

passenger’s face. In an emergency situation 

where oxygen is required, it is possible that 

certain passengers may not receive oxygen 

supply due to the increased length of the 

lanyard. 

BA has issued service bulletin (SB) 605– 

35–003 to replace the existing lanyards in the 

passenger oxygen box assemblies with 

lanyards of the correct length. Incorporation 

of this BA SB will restore the proper oxygen 

flow functionality to the passenger oxygen 

masks in the event of an emergency. 

This [Canadian] AD mandates the 

incorporation of [Bombardier] SB 605–35– 

003. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2017– 

0477. 

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 

correcting 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 

Bombardier, Inc., has issued Service 

Bulletin 605–35–003, Revision 02, dated 

April 18, 2016. This service information 

describes procedures for replacing the 

existing oxygen mask lanyards with 

lanyards of the correct length. 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. 

Costs of Compliance 

We estimate that this AD affects 120 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement ..................... 4 work-hours × $85 per hour = $340 ........................ Not available .................... $340 $40,800

Federal Register / Vol. 82, No. 160 / Monday, August 21, 2017 / Rules and Regulations 39519 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. As a result, we 

have included all costs in our cost 

estimate. 

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 transport category 

airplanes to the Director of the System 

Oversight 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 that 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 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Airbus Model A300 

series airplanes; and Model A300 B4– 

600, B4–600R, and F4–600R series 

airplanes, and Model A300 C4–605R 

Variant F airplanes (collectively called 

Model A300–600 series airplanes). The 

NPRM published in the Federal 

Register on May 31, 2017 (82 FR 24903) 

(‘‘the NPRM’’). The NPRM was 

prompted by reports of cracks initiating 

at the upper radius of frame (FR) 47 and 

a determination that the current 

inspection procedure is not reliable in 

detecting certain cracking of the forward 

fitting of FR 47. The NPRM proposed to 

require repetitive inspections to detect 

cracking of the upper radius of the 

forward fitting of FR 47, and related 

investigative actions and corrective 

actions if necessary. We are issuing this 

AD to detect and correct fatigue 

cracking of the FR 47 forward fitting 

upper radius on the left-hand and righthand sides of the fuselage, which could 

propagate and result in reduced 

structural integrity of the airplane. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2016–0150, 

dated July 25, 2016 (referred to after this 

as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

on all. The MCAI states: 

During scheduled maintenance inspections 

on the fuselage, cracks initiating at the upper 

radius of frame (FR) 47 have been reported 

on several aeroplanes. Similar damage was 

also discovered on the A300 fatigue test 

fuselage. 

This condition, if not detected and 

corrected, could reduce the structural 

integrity of the fuselage. 

Prompted by these findings, Airbus issued 

Service Bulletin (SB) A300–53–0246, SB 

A300–53–6029 and SB A300–53–9014 to 

provide inspection instructions and, 

consequently, DGAC France issued AD F– 

2006–016 to require repetitive inspections 

and corrective action. 

Since that [French] AD was issued, further 

investigation led to the conclusion that the 

current ultrasonic inspection performed in 

accordance with Airbus SB A300–53–0246 

Revision 06, or SB A300–53–6029 Revision 

08, or SB A300–53–9014 Revision 01, as 

applicable, was not reliable to detect deep 

crack going downward. 

Consequently, to ensure the crack depth is 

correctly measured whatever the crack 

direction, Airbus developed a new 

nondestructive testing method [eddy current]
