SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (SNPRM) to 

amend 14 CFR part 39 by adding an AD 

that would apply to all Airbus Defense 

and Space S.A. Model CN–235, CN– 

235–100, CN–235–200, and CN–235– 

300 airplanes; and Model C–295 

airplanes. The SNPRM published in the 

Federal Register on June 21, 2017 (82 

FR 28274) (‘‘the SNPRM’’). We preceded 

the SNPRM with a notice of proposed 

rulemaking that published in the 

Federal Register on November 25, 2016 

(81 FR 85169) (‘‘the NPRM’’). The 

NPRM proposed to require an 

inspection of motorized cross-feed fuel 

valves and, depending on findings, 

applicable corrective action(s). The 

NPRM was prompted by leakage of a 

motorized cross-feed fuel valve. The 

SNPRM proposed to require a reduced 

compliance time for the initial 

inspection, the addition of repetitive 

inspections and operational checks, and 

corrective actions if necessary. We are 

issuing this AD to detect and correct 

leaks in a motorized fuel valve, which 

could lead to failure of the fuel valve 

and consequent improper fuel system 

functioning or, in case of the presence 

of an ignition source, an airplane fire. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2017–0004, dated January 9, 

2017 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for all Airbus 

Defense and Space S.A. Model CN–235, 

CN–235–100, CN–235–200, and CN– 

235–300 airplanes; and Model C–295 

airplanes. The MCAI states: 

Leakage of a motorised cross-feed fuel 

valve Part Number (P/N) 7923227F was 

reported on a CN–235–100M aeroplane. The 

leakage was observed through the valve 

electrical connectors and detected during 

accomplishment of a functional check in 

accordance with task 28.007 of the CN–235 

Maintenance Review Board Report (MRB 

CN–235–PV01). Identical motorised fuel 

valves are installed on civilian CN–235 and 

C–295 aeroplanes, as cross-feed, shut-off and 

defueling valves. 

This condition, if not detected and 

corrected, could lead to failure of a motorised 

fuel valve and consequent improper 

functioning of the fuel system or, in case of 

an ignition source, could lead to a fire, 

possibly resulting in damage to the aeroplane 

and injury to occupants. 

To address this potentially unsafe 

condition, Airbus Defence & Space (D&S) 

issued Alert Operators Transmission (AOT)– 

CN235–28–0001 and AOT–C295–28–0001 to 

provide inspection instructions. 

Consequently, EASA issued AD 2016–0071 

to require a one-time inspection of the 

affected motorised fuel valves and, 

depending on findings, accomplishment of 

applicable corrective action(s). 

Since that [EASA] AD was issued, new 

occurrences of fuel leakage involving the 


asabaliauskas on DSKBBXCHB2PROD with RULES
44896 Federal Register / Vol. 82, No. 186 / Wednesday, September 27, 2017 / Rules and Regulations 

affected motorised fuel valves were reported 

and Airbus D&S issued Revision 1 of AOT– 

CN235–28–0001 and Revision 1 of AOT– 

C295–28–0001 to introduce repetitive 

inspections and operational checks of the 

affected motorised fuel valves. 

For the reasons described above, this 

[EASA] AD retains the requirements of EASA 

AD 2016–0071, which is superseded, and 

introduces repetitive inspections and 

operational checks [and corrective actions, if 

necessary] of the affected fuel valves. 

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–2016– 

9386. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the SNPRM 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 SNPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the SNPRM. 

Related Service Information Under 1 

CFR Part 51 

Airbus Defense and Space has issued 

Alert Operators Transmission (AOT) 

AOT–C295–28–0001, Revision 1, dated 

September 27, 2016; and AOT–CN235– 

28–0001, Revision 1, dated September 

27, 2016. This service information 

describes procedures for repetitive 

inspections, replacement of the 

motorized fuel valves, and operational 

checks and corrective actions on 

affected motorized fuel valves. These 

documents are distinct since they apply 

to different airplane models. 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 14 

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 

Inspection and operational check ................... 3 work-hours × $85 per hour = $255 ............. $0 $255 $3,570 

Reporting ......................................................... 1 work-hour × $85 per hour = $85 ................. 0 85 1,190 

We estimate the following costs to do 

any necessary replacements that will be 

required based on the results of the 

required inspection. We have no way of 

determining the number of aircraft that 

might need these replacements: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement ................................................................. 5 work-hours × $85 per hour = $425 ........................... $38,448 $38,873 

We have received no definitive data 

that will enable us to provide cost 

estimates for the on-condition corrective 

actions for the operational check 

specified in this AD. 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a current valid 

OMB control number. The control 

number for the collection of information 

required by this AD is 2120–0056. The 

paperwork cost associated with this AD 

has been detailed in the Costs of 

Compliance section of this document 

and includes time for reviewing 

instructions, as well as completing and 

reviewing the collection of information. 

Therefore, all reporting associated with 

this AD is mandatory. Comments 

concerning the accuracy of this burden 

and suggestions for reducing the burden 

should be directed to the FAA at 800 

Independence Ave. SW., Washington, 

DC 20591, ATTN: Information 

Collection Clearance Officer, AES–200. 

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.

Bombardier, Inc., Model DHC–8–401 

and –402 airplanes. This AD was 

prompted by the discovery of cracking 

on two test spoiler power control unit 

(PCU) manifolds during testing by the 

manufacturer. This AD requires 

replacement of affected spoiler PCUs. 

We are issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective November 1, 

2017. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of November 1, 2017.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (SNPRM) to 

amend 14 CFR part 39 by adding an AD 

that would apply to certain Bombardier, 

Inc., Model DHC–8–401 and –402 

airplanes. The SNPRM published in the 

Federal Register on July 14, 2017 (82 FR 

32496) (‘‘the SNPRM’’). We preceded 

the SNPRM with a notice of proposed 

rulemaking (NPRM) that published in 

the Federal Register on January 13, 

2016 (81 FR 1586) (‘‘the NPRM’’). The 

NPRM proposed to require replacement 

of affected spoiler PCUs. The NPRM was 

prompted by the discovery of cracking 

on two test spoiler PCU manifolds 

during testing by the manufacturer. The 

SNPRM proposed to require 

replacement of affected spoiler PCUs, 

and also proposed to add airplanes to 

the applicability. We are issuing this AD 

to prevent cracking of the spoiler PCUs 

that could lead to the loss of multiple 

flight controls and landing gear systems.
