AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: Extension of airbrakes 

above 360 KIAS [knots indicated air 

speed]/0.79 Mi [Mach indicated] results 

in aerodynamic driven vibration of the 

airbrake which, if not limited per 

Revision 14 to the AFM [airplane flight 

manual], can lead to high cycle fatigue 

failure of the airbrake in board hinge. 

The unsafe condition is high cycle 

fatigue of the airbrake in-board hinge, 

which can result in loss of the airbrake, 

which in turn can lead to reduced 

controllability of the airplane. The 

proposed AD would require actions that 

are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by August 9, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The Civil Aviation Authority of Israel 

(CAAI), which is the aviation authority 

for Israel, has issued Israeli 

Airworthiness Directive 01–10–01– 

07R1, dated January 20, 2010 (referred 

to after this as ‘‘the MCAI’’), to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Extension of airbrakes above 360 KIAS 

[knots indicated air speed]/0.79 Mi [Mach 

indicated] results in aerodynamic driven 

vibration of the airbrake which, if not limited 

per Revision 14 to the AFM [airplane flight 

manual], can lead to high cycle fatigue failure 

of the airbrake in board hinge. 

The unsafe condition is high cycle 

fatigue of the airbrake in-board hinge, 

which can result in loss of the airbrake, 

which in turn can lead to reduced 

controllability of the airplane. The 

required action includes revising the 

Limitations section of the Gulfstream 

200 Airplane Flight Manual to prohibit 

deploying the air brakes above the 

stated speed. You may obtain further 

information by examining the MCAI in 

the AD docket. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

mstockstill on DSKH9S0YB1PROD with PROPOSALS

Federal Register / Vol. 75, No. 122 / Friday, June 25, 2010 / Proposed Rules 36297 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a Note within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 90 products of U.S. registry. 

We also estimate that it would take 

about 1 work-hour per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$7,650, or $85 per product. 

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); 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 proposed AD and placed it in the 

AD docket. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety. 

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 AD: 

Gulfstream Aerospace LP (Type Certificate 

Previously Held by Israel Aircraft 

Industries, Ltd.): Docket No. FAA–2010– 

0555; Directorate Identifier 2010–NM– 

053–AD. 

Comments Due Date 

(a) We must receive comments by August 

9, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Gulfstream 

Aerospace LP (Type Certificate previously 

held by Israel Aircraft Industries, Ltd.) Model 

Galaxy and Gulfstream 200 airplanes, all 

serial numbers, certificated in any category. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 27: Flight controls. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

Extension of airbrakes above 360 KIAS 

[knots indicated air speed]/0.79 Mi [Mach 

indicated] results in aerodynamic driven 

vibration of the airbrake which, if not limited 

per Revision 14 to the AFM [airplane flight 

manual], can lead to high cycle fatigue failure 

of the airbrake in board hinge. 

The unsafe condition is high cycle fatigue of 

the airbrake in-board hinge, which can result 

in loss of the airbrake, which in turn can lead 

to reduced controllability of the airplane. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Actions 

(g) Within 60 days after the effective date 

of this AD: Revise the Limitations section of 

the Gulfstream 200 Airplane Flight Manual 

(AFM) to include the following statement. 

This may be done by inserting a copy of this 

AD into the AFM. 

‘‘MAXIMUM AIR BRAKES OPERATION/ 

EXTENDED SPEED 

360 KIAS/0.79 Mi

NOTE 

During emergency, air brakes may be used 

at speeds above 0.79 Mi.’’ 

Note 1: When a statement identical to that 

in paragraph (g) of this AD has been included 

in the general revisions of the AFM, the 

general revisions may be inserted into the 

AFM, and the copy of this AD may be 

removed from the AFM. 

Note 2: The Gulfstream 200 AFM applies 

to both the Model Galaxy and Gulfstream 200 

airplanes. 

FAA AD Differences 

Note 3: This AD differs from the MCAI 

and/or service information as follows: No 

differences.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede an existing airworthiness 

directive (AD) that applies to all of the 

McDonnell Douglas Corporation 

airplanes identified above. The existing 

AD currently requires revising the 

maintenance program to incorporate 

new airworthiness limitations for fuel 

tank systems to satisfy Special Federal 

Aviation Regulation No. 88 

requirements. This proposed AD would 

add requirements to revise the 

maintenance program to incorporate 

specific Critical Design Configuration 

Control Limitations (CDCCL) 

information and install fuel tank float 

switch in-line fuses. This proposed AD 

would also add two Airworthiness 

Limitations inspections (ALIs). This 

proposed AD results from a design 

review of the fuel tank systems. We are 

proposing this AD to prevent the 

potential for ignition sources inside fuel 

tanks caused by latent failures, 

alterations, repairs, or maintenance 

actions, which, in combination with 

flammable fuel vapors, could result in a 

fuel tank explosion and consequent loss 

of the airplane. 

DATES: We must receive comments on 

this proposed AD by August 9, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

On April 4, 2008, we issued AD 2008– 

09–04, Amendment 39–15484 (73 FR 

21523, April 22, 2008), for all Model 

DC–8–31, DC–8–32, DC–8–33, DC–8–41, 

DC–8–42, and DC–8–43 airplanes; 

Model DC–8–50 series airplanes; Model 

DC–8F–54 and DC–8F–55 airplanes; 

Model DC–8–60 series airplanes; Model 

DC–8–60F series airplanes; Model DC– 

8–70 series airplanes; and Model DC–8– 

70F series airplanes. That AD requires 

revising the maintenance program to 

incorporate new airworthiness 

limitations for fuel tank systems to 

satisfy Special Federal Aviation 

Regulation No. 88 requirements. That 

AD resulted from a design review of the 

fuel tank systems. We issued that AD to 

prevent the potential for ignition 

sources inside fuel tanks caused by 

latent failures, alterations, repairs, or 

maintenance actions, which, in 

combination with flammable fuel 

vapors, could result in a fuel tank 

explosion and consequent loss of the 

airplane. 

Actions Since Existing AD Was Issued 

Since we issued AD 2008–09–04, we 

have been notified that the float switch 

wires located on the leading edges of the 

left and right wings at the front spar are 

routed in the same bundles as power 

wires. If a short circuit between a float 

switch wire and a power wire occurs, an 

over-current can cause excessive 

temperatures in the float switch wires, 

resulting in damage. Adding an in-line 

fuse as a self-contained component in
