ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Bombardier Model CL–600–

2B19 (Regional Jet Series 100 & 440) 

airplanes. This proposed AD would 

require replacing the Gask-O-Seal in the 

coupling of the refuel/defuel shut-off 

valves. This proposed AD results from 

a report that Gask-O-Seals that did not 

incorporate an integral restrictor to limit 

fuel flow rate and fuel pressure during 

refueling were installed on certain 

airplanes. We are proposing this AD to 

prevent a buildup of excessive static 

charge, which could create an ignition 

source inside the fuel tank. 

DATES: We must receive comments on 

this proposed AD by November 28, 

2005. 

ADDRESSES: Use one of the following

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the airworthiness 

authority for Canada, notified us that an 

unsafe condition may exist on certain 

Bombardier Model CL–600–2B19 

(Regional Jet Series 100 & 440) 

airplanes. TCCA advises that incorrectly 

identified Gask-O-Seals have been 

installed on certain production 

airplanes and have been delivered as 

part of a modification kit for Bombardier 

Service Bulletin 601R–28–053, dated 

July 12, 2004. The incorrectly identified 

Gask-O-Seal did not incorporate an 

integral restrictor to limit fuel flow rate 

and fuel pressure during refueling. This 

condition, if not corrected, could result 

in a buildup of excessive static charge, 

which could create an ignition source 

inside the fuel tank. 

Relevant Service Information 

Bombardier has issued Alert Service 

Bulletin A601R–28–064, dated April 21, 

2005. The alert service bulletin 

describes procedures for replacing the 

Gask-O-Seal, part number (P/N) 202297, 

in the coupling of the refuel/defuel 

shut-off valves with a new Gask-O-Seal, 

P/N 601R62085–1. Accomplishing the 

actions specified in the service 

information is intended to adequately 

address the unsafe condition. TCCA 

mandated the service information and 

issued Canadian airworthiness directive 

CF–2005–18, dated June 9, 2005, to 

ensure the continued airworthiness of 

these airplanes in Canada. 

FAA’s Determination and Requirements 

of the Proposed AD 

This airplane model is manufactured 

in Canada and is type certificated for 

operation in the United States under the 

provisions of section 21.29 of the 

Federal Aviation Regulations (14 CFR 

21.29) and the applicable bilateral 

airworthiness agreement. Pursuant to 

this bilateral airworthiness agreement, 

TCCA has kept the FAA informed of the 

situation described above. We have 

examined TCCA’s findings, evaluated 

all pertinent information, and 

determined that we need to issue an AD 

for airplanes of this type design that are 

certificated for operation in the United 

States. 

Therefore, we are proposing this AD, 

which would require accomplishing the 

actions specified in the service 

information described previously. 

Costs of Compliance 

The following table provides the 

estimated costs for U.S. operators to 

comply with 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 have 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. 

61922 Federal Register / Vol. 70, No. 207 / Thursday, October 27, 2005 / Proposed Rules 

For the reasons discussed above, I 

certify that the 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); and 

3. 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. See the ADDRESSES section 

for a location to examine the regulatory 

evaluation.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Airbus Model A318–100 and A319–100 

series airplanes; Model A320–111 

airplanes; and Model A320–200, A321–

100, and A321–200 series airplanes. 

This proposed AD would require 

repetitive detailed inspections of the 

trimmable horizontal stabilizer actuator 

(THSA) attachments for proper 

clearances, and any crack, damage, or 

metallic particles; related corrective 

actions if necessary; and a report of the 

inspection results to the manufacturer. 

This proposed AD results from a report 

that during lab testing to verify the 

performance of the THSA’s secondary 

load path with a simulated failure of the 

THSA’s primary load path, the 

secondary load path’s nut did not jam 

(as it was supposed to do.) We are 

proposing this AD to ensure the 

integrity of the THSA’s primary load 

path, which if failed, could result in 

latent (undetected) loading and eventual 

failure of the THSA’s secondary load 

path and consequent uncontrolled 

movement of the horizontal stabilizer 

and loss of control of the airplane. 

DATES: We must receive comments on 

this proposed AD by November 28, 

2005.
