Series 100 & 440) Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Bombardier Model CL–600–2B19 

(Regional Jet Series 100 & 440) 

airplanes. This AD requires repetitive 

inspections of the bolts that attach the 

exhaust nozzle to the aft engine flange 

to determine if any bolts are missing or 

fractured, and replacement of the 

existing bolts with new, improved bolts. 

This AD results from reports of the 

engine exhaust nozzle and fairing 

departing from the airplane in flight due 

to missing attachment bolts. We are 

issuing this AD to detect and correct 

missing or fractured attachment bolts, 

which could lead to the loss of an 

engine exhaust nozzle during flight and 

consequent structural damage to the 

airplane and hazard to people or 

property on the ground. Damage to the 

airplane could cause the airplane to yaw 

and result in reduced controllability of 

the airplane. 

DATES: This AD becomes effective April 

3, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 


cprice-sewell on PROD1PC66 with RULES

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to certain Bombardier Model CL–

600–2B19 (Regional Jet Series 100 & 

440) airplanes. That NPRM was 

published in the Federal Register on 

December 26, 2006 (71 FR 77312). That 

NPRM proposed to require repetitive 

inspections of the bolts that attach the 

exhaust nozzle to the aft engine flange 

to determine if any bolts are missing or 

fractured, and replacement of the 

existing bolts with new, improved bolts. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed. 

Costs of Compliance 

The following table provides the 

estimated costs for U.S. operators to 

comply with this AD. 

ESTIMATED COSTS

Action Work 

hours 

Average 

labor rate 

per hour 

Parts Cost per airplane 

Number of 

U.S.- 

registered 

airplanes 

Fleet cost 

Inspection, per inspection cycle.2 $80 None ............................. $160, per inspection 

cycle.

686 $109,760, per inspection 

cycle. 

Replacement ................. 4 $80 $513 .............................. $833 .............................. 686 $571,438. 

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 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 

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 AD and placed it in the AD docket. 

See the ADDRESSES section for a location 

to examine the regulatory evaluation.

Compliance 

(e) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Repetitive Inspections 

(f) Within 1,500 flight hours after the 

effective date of this AD: For the left and 

right engine exhaust nozzles, do a detailed 

inspection of the bolts that attach the exhaust 

nozzle to the aft engine flange to determine 

if any bolts are missing or fractured, in 

accordance with Part A of the 

Accomplishment Instructions of Bombardier 

Service Bulletin 601R–78–021, dated June 2,

flight hours, until the replacement specified 

in paragraph (g) or (h) of this AD is 

accomplished. 

Note 1: For the purposes of this AD, a 

detailed inspection is: ‘‘An intensive 

examination of a specific item, installation, 

or assembly to detect damage, failure, or 

irregularity. Available lighting is normally 

supplemented with a direct source of good 

lighting at an intensity deemed appropriate. 

Inspection aids such as mirror, magnifying 

lenses, etc., may be necessary. Surface 

cleaning and elaborate procedures may be 

required.’’

Corrective Action, if Necessary 

(g) If any bolt of an engine exhaust nozzle 

is found missing or fractured during any 

inspection required by paragraph (f) of this 

AD, before further flight, replace the existing 

bolts that attach the exhaust nozzle to the aft 

engine flange with new, improved bolts, in 

accordance with Part B of the 

Accomplishment Instructions of Bombardier 

Service Bulletin 601R–78–021, dated June 2, 

2006. Accomplishing the bolt replacement 

for an engine exhaust nozzle terminates the 

repetitive inspections required by paragraph 

(f) of this AD for that engine exhaust nozzle 

only. 

Note 2: Bombardier Service Bulletin 601R–

78–021, dated June 2, 2006, refers to 

Bombardier Service Bulletin CF34-NAC–78–

024, Revision 4, dated November 10, 2005, as
