ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2B16 

(CL–601–3A, CL–601–3R, and CL–604 

Variants) airplanes. This AD was 

prompted by reports of airspeed 

mismatch between the pilot and copilot’s airspeed indicators, which 

occurred during or after heavy rain. This 

AD requires, for certain airplanes, 

inspecting for drain bottles having 

certain part numbers, and replacing 

affected drain bottles. This AD requires, 

for certain other airplanes, replacing 

drain bottles. We are issuing this AD to 

prevent pitot static tubing from 

becoming blocked by water, which if 

not corrected, could lead to erroneous 

airspeed and altitude indications, and 

consequent loss of control of the 

airplane. 

DATES: This AD becomes effective 

December 5, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of December 5, 2013.

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 the specified products. The 

NPRM was published in the Federal 

Register on April 17, 2013 (78 FR 

22806). The NPRM proposed to correct 

an unsafe condition for the specified 

products. 

Transport Canada Civil Aviation, 

which is the aviation authority for 

Canada, has issued Canadian 


wreier-aviles on DSK5TPTVN1PROD with RULES
Federal Register / Vol. 78, No. 211 / Thursday, October 31, 2013 / Rules and Regulations 65191 

Airworthiness Directive CF–2012–30, 

dated December 7, 2012 (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: 

A number of reports were received from 

the operators indicating airspeed mismatch 

between the pilot and co-pilot’s airspeed 

indicators. The erroneous indication 

occurred during or after heavy rain. Further 

investigation revealed that during heavy 

precipitation, the pitot static tubing may 

become partially or completely blocked by 

the water which didn’t enter the drain 

bottle(s). This condition, if not corrected, 

may result in erroneous airspeed and altitude 

indications [and consequent loss of control of 

the airplane]. 

This [Canadian] AD mandates [for certain 

airplanes] the replacement of the drain 

bottles to improve drainage of the pitot-static 

tubing [and, for certain other airplanes, an 

inspection for, and replacement of, certain 

drain bottles]. 

You may examine the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov/

#!documentDetail;D=FAA-2013-0332- 

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 22806, April 17, 2013) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the 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 (78 FR 

22806, April 17, 2013) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 22806, 

April 17, 2013). 

Costs of Compliance 

We estimate that this AD affects 77 

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 ................................................... 5 work-hours × $85 per hour = $425 ............. $2,939 $3,364 $259,028 

Where the service information lists 

required parts costs that are covered 

under warranty, we have assumed that 

there will be no charge for these parts. 

As we do not control warranty coverage 

for affected parties, some parties may 

incur costs higher than estimated here. 

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 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.

You may examine the AD docket on 

the Internet at http://

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all The 

Boeing Company Model 727 airplanes. 

This AD was prompted by reports 

indicating that a standard fuel tank 

access door was located where an 

impact-resistant access door was 

required, and stencils were missing 

from some impact-resistant access 

doors. This AD requires an inspection of 

the left- and right-hand wing fuel tank 

access doors to determine that impactresistant access doors are installed in 

the correct locations, and to replace any 

door with an impact-resistant access 

door if necessary. This AD also requires 

an inspection for stencils and index 

markers on impact-resistant access 

doors, and application of new stencils 

or index markers if necessary. This AD 

also requires revising the maintenance 

program to incorporate changes to the 

airworthiness limitations section. We 

are issuing this AD to prevent foreign 

object penetration of the fuel tank, 

which could cause a fuel leak near an 

ignition source (e.g., hot brakes), 

consequently leading to a fuel-fed fire. 

DATES: This AD is effective December 5, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of December 5, 2013.

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 the specified products. The 

NPRM published in the Federal 

Register on August 1, 2013 (78 FR 

46538). The NPRM proposed to require 

an inspection of the left- and right-hand 

wing fuel tank access doors to 

determine that impact-resistant access 

doors are installed in the correct 

locations, and to replace any door with 

an impact-resistant access door if 

necessary. The NPRM also proposed to 

require an inspection for stencils and 

index markers on impact-resistant 

access doors, and application of new 

stencils or index markers if necessary. 

The NPRM also proposed to require 

revising the maintenance program to 

incorporate changes to the airworthiness 

limitations section. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

The Boeing Company supported the 

NPRM (78 FR 46538, August 1, 2013). 

Conclusion 

We reviewed the relevant data, 

considered the comments received, 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 (78 FR 

46538, August 1, 2013) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 46538, 

August 1, 2013). 

Costs of Compliance 

We estimate that this AD affects 139 

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 ............................................ Up to 3 work-hours × $85 per hour = $255 ...................... $0 $255 $35,445 

Maintenance program revision ............ 1 work-hour × $85 per hour = $85 .................................... 0 85 11,815 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need these replacements:
