Airworthiness Directives; McDonnell 

Douglas Model MD–90–30 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

McDonnell Douglas Model MD–90–30 

airplanes. This AD requires installing 

fuses and wire protection in certain 

wing and fuel tank spars. This AD 

results from fuel system reviews 

conducted by the manufacturer. We are 

issuing this AD to prevent possible 

damage to the fuel level float or pressure 

switch wires. Such damage could 

become a potential ignition source 

inside the fuel tank, and, when 

combined with flammable fuel vapors, 

could result in a fuel tank explosion and 

consequent loss of the airplane. 

DATES: This AD is effective July 7, 2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of July 7, 2009.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to 

certain McDonnell Douglas Model MD– 

90–30 airplanes. That NPRM was 

published in the Federal Register on 

March 10, 2009 (74 FR 10202). That 

NPRM proposed to require installing 

fuses and wire protection in certain 

wing and fuel tank spars. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

We estimate that this AD will affect 

15 airplanes of U.S. registry. 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 

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. 

You can find our regulatory 

evaluation and the estimated costs of 

compliance in the AD Docket.

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2009–11–11 McDonnell Douglas: 

Amendment 39–15921. Docket No. 

FAA–2009–0213; Directorate Identifier

America Code 28: Fuel. 

Unsafe Condition 

(e) This AD results from fuel system 

reviews conducted by the manufacturer. We 

are issuing this AD to prevent possible 

damage to the fuel level float or pressure 

switch wires. Such damage could become a 

potential ignition source inside the fuel tank, 

and, when combined with flammable fuel 

vapors, could result in a fuel tank explosion 

and consequent loss of the airplane. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

Federal Register / Vol. 74, No. 104 / Tuesday, June 2, 2009 / Rules and Regulations 26293 

the compliance times specified, unless the 

actions have already been done. 

Installation 

(g) Within 5 years after the effective date 

of this AD, do the actions specified in 

paragraph (g)(1) or (g)(2) of this AD, as 

applicable, in accordance with the 

Accomplishment Instructions of Boeing 

Service Bulletin MD90–28–012, dated 

November 19, 2008 (‘‘the service bulletin’’). 

(1) For Group 1 airplanes identified in the 

service bulletin, install fuel level float switch 

in-line fuses and wire protection in the left 

and right wing forward spars and center fuel 

tank forward spar, right side. 

(2) For Group 2 airplanes identified in the 

service bulletin, install fuel level float switch 

in-line fuses and wire protection in the left

fuel pressure switch in-line fuse and wire 

protection in the center fuel tank forward 

spar, left side. 

Alternative Methods of Compliance 

(AMOCs)

Certification Office (ACO), FAA, has the 

authority to approve AMOCs for this AD, if 

requested using the procedures found in 14 

CFR 39.19. Send information to Attn: Samuel

(2) To request a different method of 

compliance or a different compliance time 

for this AD, follow the procedures in 14 CFR 

39.19. Before using any approved AMOC on 

any airplane to which the AMOC applies,

This deviation provides for the bridge to 

remain closed to navigation for eight 

hours with an opening at noon for the 

passage of vessels. The purpose of the 

closure is to replace parts on the bridge. 

DATES: This deviation is effective from 

7 a.m. to 3 p.m. on Tuesday, June 9, 

2009. 

ADDRESSES: Documents mentioned in 

this preamble as being available in the

SUPPLEMENTARY INFORMATION: The 

Burlington Northern Railway Company 

has requested a temporary deviation in 

order to perform necessary maintenance 

on the Conley joints of the Galveston 

Causeway Railroad Bascule Bridge 

across the Gulf Intracoastal Waterway, 

mile 357.2 west of Harvey Locks, at 

Galveston, Galveston County, Texas. 

The maintenance is essential for the 

continued safe operation of the railroad 

bridge. This temporary deviation will 

allow the bridge to remain in the closedto-navigation position from 7 a.m. until 

3 p.m. on Tuesday, June 9, 2009. The 

bridge will open for the passage of 

vessels at noon for all vessels to transit 

through the bridge. Currently, the draw 

opens on signal for the passage of 

vessels. 

The bridge has a vertical clearance of 

10 feet above mean high water in the 

closed-to-navigation position. 

Navigation at the site of the bridge 

consists mainly of tows with barges and 

some recreational pleasure craft. Due to 

prior experience, as well as 

coordination with waterway users, it 

has been determined that this closure 

will not have a significant effect on 

these vessels. No alternate routes are 

available. This closure is considered 

necessary for repair of the bridge. 

In accordance with 33 CFR 117.35(e), 

the drawbridge must return to its regular 

operating schedule immediately at the 

end of the designated time period. This 

deviation from the operating regulations 

is authorized under 33 CFR 117.35. 

Dated: May 18, 2009.

Bridge Administrator.
