ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is revising an 

existing airworthiness directive (AD), 

which applies to all McDonnell Douglas 

Model DC–9–10 series airplanes, DC–9– 

30 series airplanes, DC–9–81 (MD–81) 

airplanes, DC–9–82 (MD–82) airplanes, 

DC–9–83 (MD–83) airplanes, DC–9–87 

(MD–87) airplanes, MD–88 airplanes, 

and MD–90–30 airplanes. That AD 

currently requires modifying the flight 

deck door. This AD revises the 

applicability by removing certain 

airplanes. This AD was prompted by a 

report indicating that certain equipment 

of the flight deck door is defective. We 

are issuing this AD to prevent failure of 

this equipment, which could jeopardize 

flight safety. 

DATES: This AD is effective August 5, 

2010, to all persons except those 

persons to whom it was made 

immediately effective by AD 2009–15– 

16, issued July 15, 2009, which 

contained the requirements of this 

amendment. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of August 5, 2010. 

On July 6, 2010 (75 FR 38017, July 1, 

2010), the Director of the Federal 

Register approved the incorporation by 

reference of a certain other publication 

listed in the AD. 

We must receive any comments on 

this AD by September 20, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

On June 18, 2010, we issued AD 

2009–15–16, Amendment 39–16345 (75 

FR 38017, July 1, 2010). That AD 

applies to all McDonnell Douglas 

Corporation Model DC–9–10 series 

airplanes, DC–9–30 series airplanes, 

DC–9–81 (MD–81) airplanes, DC–9–82 

(MD–82) airplanes, DC–9–83 (MD–83) 

airplanes, DC–9–87 (MD–87) airplanes, 

MD–88 airplanes, and MD–90–30 

airplanes. That AD requires modifying 

the flight deck door. That AD was 

prompted by a report indicating that 

certain equipment of the flight deck 

door is defective. The actions specified 

in that AD are intended to prevent 

failure of this equipment, which could 

jeopardize flight safety. 

Actions Since AD Was Issued 

Since we issued that AD, we have 

learned that certain airplanes were 

incorrectly included in the 

applicability. The only airplanes subject 

to the identified unsafe condition are 

those equipped with flight deck doors 

installed in accordance with 

Supplemental Type Certificate (STC) 

ST02463AT. 

Relevant Service Information 

AD 2009–15–16 referred to TIMCO 

Service Bulletin TSB–88–52–045, 

Revision E, dated November 6, 2008, as 

the appropriate source of service 

information for the required 

modification. TIMCO has since revised 

the service bulletin. Revision G, dated 

December 8, 2009, changes Part II., 

‘‘Approval Basis,’’ by referring to STC 

ST02463AT. The procedures specified 

in Revision G of this service bulletin are 

unchanged from those in Revision E. 

FAA’s Determination and Requirements 

of this AD 

The unsafe condition described 

previously is likely to exist or develop 

on other airplanes of these same type 

designs. For this reason, we are issuing 

this AD to revise AD 2009–15–16. This 

new AD retains the requirements of the 

existing AD, and includes the following 

changes: 

• This new AD revises the 

applicability by removing airplanes that 

do not have flight deck doors installed 

in accordance with STC ST02463AT. 

• This new AD also refers to TIMCO 

Service Bulletin TSB–88–52–045, 

Revision G, dated December 8, 2009, as 

the appropriate source of service 

information for the required 

modification. 

• This new AD adds new paragraph 

(h) in this AD to give credit for actions 

done before the effective date in 

accordance with TIMCO Service 

Bulletin TSB–88–52–045, Revision F, 

dated November 2, 2009. 

FAA’s Justification and Determination 

of the Effective Date 

Certain defective equipment of the 

flight deck door could result in failure 

of the equipment and jeopardize flight 

safety. Because of our requirement to 

promote safe flight of civil aircraft and 

thus the critical need to ensure the 

proper functioning of the flight crew 

door, as well as the short compliance 

time involved with this action and the 

need to advise operators of the reduced 

applicability, this AD must be issued 

immediately. 

Because an unsafe condition exists 

that requires the immediate adoption of 

this AD, we find that notice and 

opportunity for prior public comment 

hereon are impracticable and that good 

cause exists for making this amendment 

effective in less than 30 days.

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not provide you with notice and 

an opportunity to provide your 

comments before it becomes effective. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2010–0702; Directorate Identifier 2010– 

NM–144–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this AD. We will consider all 

comments received by the closing date 

and may amend this AD because of 

those comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about 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 the 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 AD and placed it in the AD docket. 

See the ADDRESSES section for a location 

to examine the regulatory evaluation.

AGENCY: Federal Aviation 

Administration, DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: This amendment adopts a 

new airworthiness directive (AD) for the 

specified Eurocopter France helicopters. 

This action requires inspecting certain 

electrical harnesses for damage and if 

damage is found, repairing the electrical 

harness; protecting the electrical 

harness from damage; installing harness 

clamp blocks; and inspecting each 

fairing attachment screw to determine 

the length and replacing attachment 

screws, if they exceed a certain length. 

This amendment is prompted by a 

report of an in-flight incident that led to 

the inflation of the emergency floatation 

gear (emergency floats) and the 

activation of various warnings. The 

actions specified in this AD are 

intended to prevent interference 

between an electrical harness and the 

lower structure fairing attachment 

screws. Damage to an electrical harness 

by a lower structure fairing attachment 

screw could lead to short-circuiting of 

various warnings, inflation of the 

emergency floats during flight, and 

subsequent loss of control of the 

helicopter. 

DATES: Effective August 20, 2010. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of August 20, 

2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

This amendment adopts a new AD for 

Eurocopter France Model EC 130 B4 

helicopters that have been modified in 

accordance with MOD 073774, and have 

not had MOD 073591 nor the 

modification specified in Eurocopter 

Drawing No. 350A085340 incorporated. 

This action requires, within 10 hours 

time-in-service (TIS), removing the 

lower forward right-hand, left-hand, and 

center lower structure fairings (fairings); 

inspecting each electrical harness for 

chaffing, tears, holes, or other damage at 

the location of each attachment screw 

and repairing any damage; protecting 

electrical harnesses by wrapping them 

with electrical tape; installing harness 

clamp blocks; and inspecting each 

attachment screw to determine the 

length and replacing any attachment 

screw that is longer than 14mm. This 

amendment is prompted by a report of 

an in-flight incident in which an 

attachment screw that secures the righthand lower center fairing damaged the 

electrical harness and caused several 

short circuits, resulting in the described 

incident. This condition, if not detected, 

could lead to inflation of the emergency 

floats during flight, and subsequent loss 

of control of the helicopter. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2006– 

0344 R1, dated May 10, 2007, to correct 

an unsafe condition for Eurocopter 

France Model EC 130 B4 helicopters. 

EASA advises that their AD was 

initially issued as an Emergency AD, 

following a report of an in-flight 

incident which led to activation of 

various warning lights and inflation of 

the emergency floats. The pilot was able 

to land the helicopter without damage. 

EASA AD No. 2006–0344 R1 revises 

EASA Emergency AD 2006–0344–E, 

dated November 13, 2006. 

Related Service Information 

Eurocopter France has issued 

Emergency Alert Service Bulletin 

(EASB) No. 88A001 R1, dated April 17, 

2007, which specifies procedures for 

detecting and correcting interference 

between an electrical harness and a 

fairing attachment screw. The EASA 

classified this EASB as mandatory and 

issued AD No. 2006–0344 R1, dated 

May 10, 2007, to ensure the continued 

airworthiness of these helicopters.
