ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model DHC–8–400 

series airplanes. This proposed AD was 

prompted by reports of two in-service 

incidents where one side of the main 

landing gear (MLG) did not achieve 

down-lock. This proposed AD would 

require a detailed inspection of the apex 

joints of the stabilizer brace lock link in 

the MLG for clearance; rectifying and 

repairing the clearance gap, if necessary; 

and lubricating the apex joints of the 

stabilizer brace lock link in the MLG. 

We are proposing this AD to detect and 

correct insufficiently greased stabilizer 

brace lock linkage of the MLG and overtorqued lock linkage attachment bolts, 

which could lead to the failure to 

extend and down-lock the MLG, and 

could affect the safe landing of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by May 23, 2014.

Discussion 

The Transport Canada Civil Aviation, 

which is the aviation authority for 

Canada, has issued Canadian 

Airworthiness Directive CF–2013–19, 

dated July 18, 2013 (referred to after this 

as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

There have been two reported in-service 

incidents where one side of the main landing 

gear (MLG) did not achieve down-lock 

resulting in a gear unsafe indication. In both 

cases, the MLG was ultimately extended and 

down-lock was achieved through the use of 

the alternate extension system or by cycling 

the MLG. The investigation revealed that in 

both cases, the MLG stabilizer brace lock 

linkages were insufficiently greased and the 

lock linkage attachment bolts were overtorqued. 

Failure to extend and down-lock the MLG 

could adversely affect the safe landing of the 

aeroplane. 

This [TCCA] AD mandates the [detailed] 

inspection, rectification [and repair the 

clearance gap] as required, and lubrication of 

both MLG stabilizer brace lock link apex 

joints. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating it in Docket No. FAA– 

2014–0188. 

Relevant Service Information 

Bombardier, Inc. has issued Service 

Bulletin 84–32–121, dated May 27, 

2013. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This 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 the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Repair Approvals 

In many FAA transport ADs, when 

the service information specifies to 

contact the manufacturer for further 

instructions if certain discrepancies are 

found, we typically include in the AD 

a requirement to accomplish the action 

using a method approved by either the 

FAA or the State of Design Authority (or 

its delegated agent). We have recently 

been notified that certain laws in other 

countries do not allow such delegation 

of authority, but some countries do 

recognize design approval 

organizations. In addition, we have 

become aware that some U.S. operators 

have used repair instructions that were 

previously approved by a State of 

Design Authority or a Design Approval 

Holder (DAH) as a method of 

compliance with this provision in FAA 

ADs. Frequently, in these cases, the 

previously approved repair instructions 

come from the airplane structural repair 

manual or the DAH repair approval 

statements that were not specifically 

developed to address the unsafe 

condition corrected by the AD. Using 

repair instructions that were not 

specifically approved for a particular 

AD creates the potential for doing 

repairs that were not developed to 

address the unsafe condition identified 

by the MCAI AD, the FAA AD, or the 

applicable service information, which 

could result in the unsafe condition not 

being fully corrected. 

To prevent the use of repairs that 

were not specifically developed to 

correct the unsafe condition, certain 

requirements of this proposed AD 

would require that the repair approval 

specifically refer to the FAA AD. This 

change is intended to clarify the method 

of compliance and to provide operators 

with better visibility of repairs that are 

specifically developed and approved to 

correct the unsafe condition. In 

addition, we use the phrase ‘‘its 

delegated agent, or the DAH with State 

of Design Authority design organization 

approval, as applicable’’ in this 

proposed AD to refer to a DAH 

authorized to approve certain required 

repairs for this proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 75 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection and Lubrication .............................. $3 work-hours × $85 per hour = $255 ........... $0 $255 $19,125 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition actions 

specified in this proposed AD. 

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 


rmajette on DSK2TPTVN1PROD with PROPOSALS
Federal Register / Vol. 79, No. 67 / Tuesday, April 8, 2014 / Proposed Rules 19301 

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.
