AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

McDonnell Douglas Model MD–90–30 

airplanes. This proposed AD would 

require installing new fire handle 

shutoff system wiring. This proposed 

AD was prompted by a possible latent 

failure in the fire handle shutoff relay 

circuit due to a lack of separation 

between engine wires. We are proposing 

this AD to minimize the possibility of a 

multiple engine shutdown due to single 

fire handle activation. 

DATES: We must receive comments on 

this proposed AD by December 20, 

2010. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2010–1043; Directorate Identifier 2010– 

NM–200–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed 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 proposed AD. 

Discussion 

We have received a report from 

Boeing identifying a potential unsafe 

condition. The engine fire shutoff 

handles on the MD–90 airplanes are 

designed to shutoff fuel at both the wing 

spar’s mechanical fuel fire shutoff valve 

and the electrical solenoid controlled 

engine fuel shutoff valve in the engine 

Hydromechanical Unit (HMU). Due to 

the lack of separation between engine 

wires, a latent failure in the fire handle 

fuel shutoff relay circuit has the 

potential of causing a dual engine 

shutdown in the event any single engine 

fuel fire shutoff handle is activated. 

Separating the fire handle shutoff 

system wiring will minimize the 

possibility of multiple engine shutdown 

due to a single event. This condition, if 

not corrected, has the potential of 

causing a dual engine shutdown in the 

event of any single engine fuel fire 

shutoff handle activation. 

Relevant Service Information 

We reviewed Boeing Alert Service 

Bulletin MD90–74A002, dated August 

17, 2010. The service information 

describes procedures for installing new 

fire handle shutoff system wiring. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 25 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

68246 Federal Register / Vol. 75, No. 214 / Friday, November 5, 2010 / Proposed Rules 

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 determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed 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), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

McDonnell Douglas Corporation: Docket No. 

FAA–2010–1043; Directorate Identifier 

2010–NM–200–AD. 

Comments Due Date 

(a) We must receive comments by 

December 20, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to all McDonnell 

Douglas Corporation Model MD–90–30 

airplanes, certificated in any category. 

Subject 

(d) Joint Aircraft System Component 

(JASC)/Air Transport Association (ATA) of 

America Code 74: Ignition system. 

Unsafe Condition 

(e) This AD was prompted by a possible 

latent failure in the fire handle shutoff relay 

circuit due to a lack of separation between 

engine wires. We are proposing this AD to 

minimize the possibility of a multiple engine 

shutdown due to single fire handle 

activation. 

Compliance 

(f) Comply with this AD within the 

compliance times specified, unless already 

done. 

Wire Installation 

(g) Within 4,200 flight hours after the 

effective date of this AD, install new fire 

handle shutoff system wiring, in accordance 

with the Accomplishment Instructions of 

Boeing Alert Service Bulletin MD90–74A002, 

dated August 17, 2010. 

Alternative Methods of Compliance 

(AMOCs) 

(h)(1) The Manager, Los Angeles Aircraft 

Certification Office, FAA, has the authority to 

approve AMOCs for this AD, if requested 

using the procedures found in 14 CFR 39.19. 

In accordance with 14 CFR 39.19, send your 

request to your principal inspector or local 

Flight Standards District Office, as 

appropriate. If sending information directly 

to the manager of the ACO, send it to the 

attention of the person identified in the 

Related Information section of this AD. 

(2) Before using any approved AMOC, 

notify your Principal Maintenance Inspector 

or Principal Avionics Inspector, as 

appropriate, or lacking a principal inspector,

ACTION: Notice of proposed rulemaking

SUMMARY: The FAA proposes to 

supersede an existing airworthiness 

directive (AD) that applies to all Model 

DC–10–10, DC–10–10F, DC–10–15, DC– 

10–30, DC–10–30F (KC–10A and KDC– 

10), DC–10–40, DC–10–40F, MD–10– 

10F, MD–10–30F, MD–11, and MD–11F 

airplanes. The existing AD currently 

requires an inspection to determine if a 

certain fuel pump housing electrical 

connector is installed. The existing AD 

also requires a revision to the FAAapproved airplane flight manual (AFM) 

to advise the flightcrew of the 

appropriate procedures for disabling 

certain fuel pump electrical circuits 

following failure of a fuel pump housing 

electrical connector if applicable. The 

existing AD also requires the 

deactivation of certain fuel tanks or fuel 

pumps and the installation of placards 

if applicable. The existing AD allows 

the optional replacement of the fuel 

pump housing electrical connectors 

with new, improved parts, which would
