Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt 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 proposed AD 

was prompted by reports of airspeed 

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

occurred during or after heavy rain. This 

proposed AD would require, for certain 

airplanes, inspecting for drain bottles 

having certain part numbers, and 

replacing affected drain bottles. This 

proposed AD would require, for certain 

other airplanes, replacing drain bottles. 

We are proposing 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: We must receive comments on 

this proposed AD by June 3, 2013. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

Transport Canada Civil Aviation, 

which is the aviation authority for 

Canada, has issued Canadian 

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 obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

Bombardier, Inc. has issued the 

following service bulletins. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

• Bombardier Service Bulletin 601– 

0617, Revision 03, dated December 20, 

2012. 

• Bombardier Service Bulletin 604– 

34–065, Revision 02, dated December 

20, 2012. 

• Bombardier Service Bulletin 605– 

34–027, Revision 02, dated December 

20, 2012. 

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. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 77 products of U.S. registry. 

We also estimate that it would take 

about 5 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost up to $2,939 per 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 78, No. 74 / Wednesday, April 17, 2013 / Proposed Rules 22807 

product. 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. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$259,028, or $3,364 per product. 

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 

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 proposed AD and placed it in the 

AD docket. 

List of Subjects in 14 CFR Part 39

RIN 1625–AA08 

Special Local Regulations; Pro HydroX Tour, Lake Dora; Tavares, FL 

AGENCY: Coast Guard, DHS. 

ACTION: Notice of proposed rulemaking. 

SUMMARY: The Coast Guard proposes to 

establish a special local regulation on 

the waters on Lake Dora in Tavares, 

Florida during the Pro Hydro-X Tour, a 

series of high-speed personal watercraft 

races. The event is scheduled to take 

place on Saturday and Sunday, June 1– 

2 and June 8–9, 2013. Approximately 75 

vessels are anticipated to participate in 

the races. This special local regulation 

is necessary to ensure the safety of life 

on navigable waters of the United States 

during the races. The special local 

regulation would consist of the 

following two areas during each 

weekend of its enforcement: (1) A race 

area, where all persons and vessels, 

except those persons and vessels 

participating in the high-speed personal 

watercraft races, are prohibited from 

entering, transiting, anchoring, or 

remaining; and (2) a buffer zone around 

the race area, where all persons and 

vessels, except those persons and 

vessels enforcing the buffer zone, or 

authorized participants and vessels 

transiting to the race area, are prohibited 

from entering, transiting, anchoring, or 

remaining unless authorized by the 

Captain of the Port Jacksonville or a 

designated representative. 

DATES: Comments and related material 

must be received by the Coast Guard on 

or before May 17, 2013. Requests for 

public meetings must be received by the 

Coast Guard on or May 1, 2013.
