AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

BAE Systems (Operations) Limited 

Model BAe 146 airplanes. This AD 

requires repetitive inspections to 

measure the depth of chafing or scoring 

in the skin along the full length of the 

wing-to-fuselage fairing from forward to 

aft ends at the contact between the seal 

and fuselage, and related investigative/ 

corrective actions if necessary. This AD 

results from a report of chafing in this 

area. We are issuing this AD to detect 

and correct such chafing or scoring, 

which could result in reduced structural 

integrity of the fuselage. 

DATES: This AD becomes effective 

November 2, 2006. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of November 2, 2006.

Discussion 

The FAA issued a supplemental 

notice of proposed rulemaking (NPRM) 

to amend 14 CFR part 39 to include an 

AD that would apply to certain BAE 

Systems (Operations) Limited Model 

BAe 146 airplanes. That supplemental 

NPRM was published in the Federal 

Register on April 5, 2006 (71 FR 17037). 

That supplemental NPRM proposed to 

require repetitive inspections to 

measure the depth of chafing or scoring 

in the skin along the full length of the 

wing-to-fuselage fairing from forward to 

aft ends at the contact between the seal 

and fuselage, and related investigative/ 

corrective actions if necessary. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comment we received on 

the supplemental NPRM. 

Request for Revised Compliance Time 

BAE notes that corresponding British 

airworthiness directive G–2005–0020, 

dated July 6, 2005, allows an additional 

4,000 flight cycles before previously 

inspected airplanes must be 

reinspected. But paragraph (f) of the 

supplemental NPRM would require all 

airplanes to be inspected before the 

airplane accumulates 1,000 total flight 

cycles, or within a grace period of 500 

flight cycles, without any provision for 

an extended compliance time for 

airplanes previously inspected in 

accordance with both BAE Systems 

(Operations) Limited Inspection Service 

Bulletins ISB.53–005, Revision 2, dated 

February 16, 2005, and ISB.53–067, 

Revision 3, dated June 27, 2005. BAE 

adds that there are no airplanes in 

service with fewer than 1,000 total flight 

cycles. 

We infer that the commenter requests 

that we revise the supplemental NPRM. 

We agree. We have revised paragraph (f) 

to allow the deferral of certain 

corrective actions under specific 

conditions outlined in the service 

bulletins, as provided in new paragraph 

(h) in this AD. 

Additional Changes to Supplemental 

NPRM 

The supplemental NPRM specified 

that all actions including corrective 

actions would be required at the times 

specified in BAE Systems (Operations) 

Limited Inspection Service Bulletins 

ISB.53–005 and ISB.53–067. Our intent 

was to match the specifications of the 

service bulletins, which allow deferred 

corrective action only under certain 

conditions. To clarify the required 

compliance times of this AD, we have 

added new paragraph (h) to explicitly 

require corrective actions before further 

flight, except when repair may be 

deferred under the specific conditions 

noted in the service bulletins. 

Paragraph (g) of the supplemental 

NPRM specified making repairs using a 

method approved by either the FAA or 

the Civil Aviation Authority, which is 

the airworthiness authority for the 

United Kingdom. The European 

Aviation Safety Agency (EASA) has 

assumed responsibility for the airplane 

model subject to this AD. Therefore, we 

have revised paragraph (g) of this AD to 

specify making repairs using a method 

approved by the FAA, the CAA (or its 

delegated agent), or the EASA (or its 

delegated agent). 

Conclusion 

We have carefully reviewed the 

available data, including the comments 

received, and determined that air safety 

and the public interest require adopting 

the AD with the changes described 

previously. We have determined that 

these changes will neither increase the 

economic burden on any operator nor 

increase the scope of the AD. 

Costs of Compliance 

The following table provides the 

estimated costs for U.S. operators to 

comply with this 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 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.

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD), 

which applies to certain Boeing Model 

747 airplanes. That AD currently 

requires inspections to detect 

disbonding, corrosion, and cracking at 

the longitudinal rows of fasteners in the 

bonded skin panels in section 41 of the 

fuselage, and repair, if necessary. This 

new AD adds airplanes to the 

applicability, and requires new 

inspections of airplanes that may have 

Alodine-coated rivets installed. This AD 

results from a report of cracking 

discovered in a skin lap joint that was 

previously inspected using the eddy 

current method. We are issuing this AD 

to prevent rapid decompression of the 

airplane due to disbonding and 

subsequent cracking of the skin panels. 

DATES: This AD becomes effective 

November 2, 2006. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of November 2, 2006. 

On November 27, 1996 (61 FR 57994, 

November 12, 1996), the Director of the 

Federal Register approved the 

incorporation by reference of Boeing 

Alert Service Bulletin 747–53A2409, 

dated September 26, 1996.

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that 

supersedes AD 96–23–02, amendment 

39–9807 (61 FR 57994, November 12, 

1996). The existing AD applies to 

certain Boeing Model 747 series 

airplanes. That NPRM was published in 

the Federal Register on May 25, 2006 

(71 FR 30090). That NPRM proposed to 

continue to require inspections to detect 

disbonding, corrosion, and cracking at 

the longitudinal rows of fasteners in the 

bonded skin panels in section 41 of the 

fuselage, and repair, if necessary. That 

NPRM also proposed to add airplanes to 

the applicability of the existing AD, and 

require new inspections of airplanes 

that may have Alodine-coated rivets 

installed. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comments that have 

been received on the NPRM. 

Support for the NPRM 

Boeing supports the NPRM.
