AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Hawker Beechcraft Corporation Model 

390 airplanes. This AD requires you to 

inspect the essential bus lightning strike 

protection for proper installation of 

metal oxide varistor (MOV) and spark 

gap wiring. This AD also requires you 

to rework the wiring as necessary to 

achieve the required lightning strike/ 

surge protection. This AD results from 

a report that the wires to the MOV and 

spark gap were swapped. We are issuing 

this AD to detect and correct improper 

installation of the MOV and spark gap 

wiring, which could result in overload 

of the MOV in a lightning strike and 

allow electrical energy to continue to 

the essential bus and disable equipment 

that receives power from the essential 

bus. The disabled equipment could 

include the autopilot, anti-skid system, 

hydraulic indicator, spoiler system, 

pilot primary flight display, audio 

panel, or the #1 air data computer. This 

failure could lead to a significant 

increase in pilot workload during 

adverse operating conditions. 

DATES: This AD becomes effective on 

June 21, 2010. 

On June 21, 2010, the Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

On February 16, 2010, we issued a 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

include an AD that would apply to 

certain Hawker Beechcraft Corporation 

Model 390 airplanes. This proposal was 

published in the Federal Register as a 

notice of proposed rulemaking (NPRM) 

on February 23, 2010 (75 FR 8001). The 

NPRM proposed to require you to 

inspect the essential bus lightning strike 

protection for proper installation of 

metal oxide varistor (MOV) and spark 

gap wiring. The NPRM also proposed to 

require you to rework the wiring as 

necessary to achieve the required 

lightning strike/surge protection. 

Comments 

We provided the public the 

opportunity to participate in developing 

this AD. We received no comments on 

the proposal 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 except for 

minor editorial corrections. We have 

determined that these minor 

corrections: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Costs of Compliance 

We estimate that this AD affects 170 

airplanes in the U.S. registry. 

We estimate the following costs to do 

the inspection (includes any necessary 

follow-on action):

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 AD. 

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 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 summary of the costs 

to comply with this AD (and other 

information as included in the 

Regulatory Evaluation) and placed it in 

the AD Docket. You may get a copy of 

this summary by sending a request to us 

at the address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2010–0158; 

Directorate Identifier 2010–CE–006–AD’’ 

in your request.

wiring, which could result in overload of the 

MOV in a lightning strike and allow 

electrical energy to continue to the essential 

bus and disable equipment that receives 

power from the essential bus. The disabled 

equipment could include the autopilot, antiskid system, hydraulic indicator, spoiler 

system, pilot primary flight display, audio 

panel, or the #1 air data computer. This 

failure could lead to a significant increase in 

pilot workload during adverse operating 

conditions.

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 Model 747 

airplanes. That AD currently requires 

repetitive inspections to detect cracking 

in certain fuselage skin lap joints, and 

repair if necessary. This new AD 

expands the inspection area in the 

existing AD, adds a modification of 

certain lap joints, and adds certain postrepair inspections of the lap joints. 

Accomplishing the modification ends 

the repetitive inspections required by 

the existing AD for the length of lap 

joint that is modified. This AD results 

from a structural review of affected skin 

lap joints for widespread fatigue 

damage. We are issuing this AD to 

prevent fatigue cracking in certain lap 

joints, which could result in rapid 

depressurization of the airplane. 

DATES: This AD becomes effective June 

21, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of June 21, 2010. 

On July 13, 1994 (59 FR 30277, June 

13, 1994), the Director of the Federal 

Register approved the incorporation by 

reference of certain other publications 

listed in the AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that 

supersedes AD 94–12–04, Amendment 

39–8932 (59 FR 30277, June 13, 1994). 

The existing AD applies to certain 

Model 747 airplanes. That NPRM was 

published in the Federal Register on 

November 18, 2009 (74 FR 59488). That 

NPRM proposed to continue to require 

repetitive inspections to detect cracking 

in certain fuselage skin lap joints, and 

repair if necessary. That NPRM also 

proposed to expand the inspection area 

in the existing AD, add a modification 

of certain lap joints, and add certain 

post-repair inspections of the lap joints. 

That NPRM specified that 

accomplishing the modification would 

end the repetitive inspections required 

by the existing AD for the length of lap 

joint that is modified. 

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. 

Request for Certain Clarifications 

Boeing asks that we provide the 

following clarifications: 

• Include language in paragraph (c) of 

the NPRM which specifies that 

airplanes having line number 629, 635, 

637, 650, 666, 667, 673, 675, 683, 713, 

750, or 810 are Group 5 airplanes. 

Boeing states that after Boeing Service 

Bulletin 747–53A2367, Revision 3, 

dated January 15, 2009, was released, it 

was determined that these airplanes do 

not have a lower lobe air stair door and 

should have been included in Group 5, 

not Group 10. 

We agree with Boeing’s request for the 

reason provided. The airplane grouping 

is incorrect in Boeing Alert Service 

Bulletin 747–53A2367, Revision 2, 

dated October 30, 2008, and Boeing 

Service Bulletin 747–53A2367, Revision 

3, dated January 15, 2009. Therefore, we 

have added a new Note 1 after 

paragraph (c) of this AD to clarify the 

correct airplane grouping for airplanes 

having the identified line numbers. 

• Change the term ‘‘Delegation Option 

Authorization’’ (DOA) to ‘‘Organization 

Designation Authorization’’ (ODA) 

throughout the NPRM. 

We agree. Boeing Commercial 

Airplanes has received an Organization 

Designation Authorization (ODA), 

which replaces the previous designation 

as a Delegation Option Authorization 

(DOA) holder. We have changed 

paragraph (m)(3) of this AD to add 

delegation of authority to Boeing 

Commercial Airplanes ODA to approve 

an alternative method of compliance for 

any repair required by this AD. 

• Change the Discussion section of 

the NPRM to note that AD 2009–04–16, 

Amendment 39–15822 (74 FR 8737, 

February 26, 2009), supersedes AD 

2008–10–15, Amendment 39–15522 (73 

FR 29042, May 20, 2008). Although we 

agree that AD 2009–04–16 superseded 

AD 2008–10–15, the discussion section 

of the NPRM is not carried over to this 

final rule. Therefore, we have made no 

change to the AD in this regard.
