Airworthiness Directives; Bombardier 

Model CL–600–2B19 (Regional Jet 

Series 100 & 440) Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: This amendment adopts a 

new airworthiness directive (AD), 

applicable to certain Bombardier Model 

CL–600–2B19 (Regional Jet Series 100& 

440) airplanes, that requires performing 

an inspection of the electrical harnesses 

of the spoiler and the brake pressure 

sensor unit on both sides of the wing 

root to detect any chafing or wire 

damage, and repairing or replacing any 

damaged or chafed harness or wire with 

a new harness, as applicable. This 

action also provides/requires a 

terminating modification for the onetime inspection. The actions specified 

by this AD are intended to detect and 

correct chafing of the electrical cables of 

the spoiler and brake pressure sensor 

unit on both sides of the wing root, 

which could result in loss of the flight 

control system and consequent reduced 

controllability of the airplane. This 

action is intended to address the 

identified unsafe condition. 

DATES: Effective October 11, 2005. 

The incorporation by reference of a 

certain publication listed in the 

regulations is approved by the Director 

of the Federal Register as of October 11, 

2005. 

ADDRESSES: The service information 

referenced in this AD may be obtained 

from Bombardier, Inc., Canadair,

SUPPLEMENTARY INFORMATION: A 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

include an airworthiness directive (AD) 

that is applicable to certain Bombardier 

Model CL–600–2B19 (Regional Jet 

Series 100 & 440) airplanes was 

published as a supplemental notice of 

proposed rulemaking (NPRM) in the 

Federal Register on June 27, 2005 (70 

FR 36862). That action proposed to 

require performing an inspection of the 

electrical harnesses of the spoiler and 

the brake pressure sensor unit on both 

sides of the wing root to detect any 

chafing or wire damage, and repairing or 

replacing any damaged or chafed 

harness or wire with a new harness, as 

applicable. The action also proposed to 

require performing a terminating 

modification for the one-time 

inspection. 

Comments 

Interested persons have been afforded 

an opportunity to participate in the 

making of this amendment. We received 

no comments on the proposed AD or on 

the determination of the cost to the 

public. 

Conclusion 

After careful review of the available 

data, the FAA has determined that air 

safety and the public interest require the 

adoption of the rule as proposed. 

Cost Impact 

The FAA estimates that 709 airplanes 

of U.S. registry will be affected by this 

AD. 

It will take approximately 1 work 

hour per airplane to accomplish the 

required inspection, at the average labor 

rate of $65 per work hour. Based on 

these figures, the cost impact of the 

inspection required by this AD on U.S. 

operators is estimated to be $46,085, or 

$65 per airplane. 

It will take approximately 5 work 

hours per airplane to accomplish the 

required modification, at the average 

labor rate of $65 per work hour. 

Required parts will be supplied by the 

airplane manufacturer at no cost to 

operators. Based on these figures, the 

cost impact of the modification required 

by this AD on U.S. operators is 

estimated to be $230,425, or $325 per 

airplane. 

The cost impact figures discussed 

above are based on assumptions that no 

operator has yet accomplished any of 

the requirements of this AD action, and 

that no operator would accomplish 

those actions in the future if thisAD 

were not adopted. The cost impact 

figures discussed in AD rulemaking 

actions represent only the time 

necessary to perform the specific actions 

actually required by the AD. These 

figures typically do not include 

incidental costs, such as the time 

required to gain access and close up, 

planning time, or time necessitated by 

other administrative actions. 

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 Impact 

The regulations adopted herein 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. Therefore, it is 

determined that this final rule does not 

have federalism implications under 

Executive Order 13132. 

For the reasons discussed above, I 

certify that this action (1) is not a 

‘‘significant regulatory action’’ under 

Executive Order 12866; (2) is not a 

‘‘significant rule’’ under 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. A final evaluation has 

Federal Register / Vol. 70, No. 171 / Tuesday, September 6, 2005 / Rules and Regulations 52903 

been prepared for this action and it is 

contained in the Rules Docket. A copy 

of it may be obtained from the Rules 

Docket at the location provided under 

the caption ADDRESSES.

Compliance: Required as indicated, unless 

accomplished previously. 

To detect and correct chafing of the

the flight control system and consequent 

reduced controllability of the airplane, 

accomplish the following: 

Initial Inspections 

(a) Within 500 flight hours after the 

effective date of this AD, do a general visual 

inspection for chafing or wire damage of the

obvious damage, failure, or irregularity. This 

level of inspection is made from within 

touching distance unless otherwise specified. 

A mirror may be necessary to enhance visual 

access to all exposed surfaces in the 

inspection area. This level of inspection is 

made under normally available lighting 

conditions such as daylight, hangar lighting, 

flashlight, or droplight and may require 

removal or opening of access panels or doors. 

Stands, ladders, or platforms may be required 

to gain proximity to the area being checked.’’

Corrective Actions 

(b) If any damaged or chafed electrical 

harness or wire is found during any 

inspection required by paragraph (a) of this 

AD, before further flight, do either paragraph 

(b)(1) or (b)(2) of this AD.
