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 that would 

supersede an existing AD. 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: Incomplete 

closure of the MED [main entry door] 

may be followed by in-flight opening of 

the door. As a result, the MED and the 

adjacent fuselage structure may be 

damaged during opening and landing 

impact. Damage to the left engine by 

flying debris and objects may also occur. 

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 March 25, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

On January 23, 2007, we issued AD 

2007–03–05, Amendment 39–14916 (72 

FR 4414, January 31, 2007). That AD 

required actions intended to address an 

unsafe condition on the products listed 

above. 

Since we issued AD 2007–03–05, the 

Civil Aviation Administration of Israel 

(CAAI), which is the aviation authority 

for Israel, has issued Israeli 

Airworthiness Directive 31–06–11–05, 

dated May 27, 2009 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

To increase pilots’ awareness to the 

possibility of incomplete closure of the Main 

Entry Door (MED) by the following means: 

WReier-Aviles on DSKGBLS3C1PROD with PROPOSALS

6158 Federal Register / Vol. 75, No. 25 / Monday, February 8, 2010 / Proposed Rules 

1. Splitting the common caution light 

CABIN DOOR signaling both MED Improper 

Closure and MED Inflatable Seal Failure into 

two separate lights: CABIN DOOR and 

CABIN DOOR SEAL. 

2. Converting the separated CABIN DOOR 

Caution light into a Warning light by 

changing its color to red. 

Note: Aircraft Flight Manuals (AFM’S) 

refer to these changes as MOD G1–20052. 

Incomplete closure of the MED may be 

followed by in-flight opening of the door. As 

a result, the MED and the adjacent fuselage 

structure may be damaged during opening 

and landing impact. 

Damage to the left engine by flying 

debris and objects may also occur. 

Required actions include modifying the 

warning and caution lights panel 

(WACLP), changing the WACLP and 

MED wiring, changing the wiring 

harness connecting the MED to the 

WACLP, and ensuring the Log of 

Modification of the AFM includes 

reference to MOD G1–20052. You may 

obtain further information by examining 

the MCAI in the AD docket. 

Relevant Service Information 

Gulfstream has issued Service 

Bulletin 100–31–284, dated August 17, 

2006. Honeywell has issued Service 

Bulletin 80–0548–31–0002, dated March 

1, 2006; Service Bulletin 80–5090–31– 

0001, dated March 1, 2006; and Service 

Bulletin 80–0548–31–0001, dated April 

1, 2006. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

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 

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 120 products of U.S. 

registry. 

The actions that are required by AD 

2007–03–05 and retained in this 

proposed AD take about 1 work-hour 

per product, at an average labor rate of 

$80 per work hour. Based on these 

figures, the estimated cost of the 

currently required actions is $80 per 

product. 

We estimate that it would take about 

60 additional work-hours per product to 

comply with the new basic 

requirements of this proposed AD. 

Required parts would cost about $600 

per product. The average labor rate is 

$80 per work-hour. Where the service 

information lists required parts costs 

that are covered under warranty, we 

have assumed that there will be no 

charge for these costs. As we do not 

control warranty coverage for affected 

parties, some parties may incur costs 

higher than estimated here. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$648,000, or $5,400 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

Federal Register / Vol. 75, No. 25 / Monday, February 8, 2010 / Proposed Rules 6159 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

To increase pilots’ awareness to the 

possibility of incomplete closure of the Main 

Entry Door (MED) by the following means: 

1. Splitting the common caution light 

CABIN DOOR signaling both MED Improper 

Closure and MED Inflatable Seal Failure into 

two separate lights: CABIN DOOR and 

CABIN DOOR SEAL. 

2. Converting the separated CABIN DOOR 

Caution light into a Warning light by 

changing its color to red. 

NOTE: Aircraft Flight Manuals (AFM’S) 

refer to these changes as MOD G1–20052. 

Incomplete closure of the MED may be 

followed by in-flight opening of the door. As 

a result, the MED and the adjacent fuselage 

structure may be damaged during opening 

and landing impact. 

Damage to the left engine by flying debris 

and objects may also occur. 

Required actions include modifying the 

warning and caution lights panel (WACLP), 

changing the WACLP and MED wiring, 

changing the wiring harness connecting the 

MED to the WACLP, and ensuring the Log of 

Modification of the AFM includes reference 

to MOD G1–20052. 

Restatement of Requirements of AD 2007– 

03–05, With No Changes: 

(f) Unless already done, do the following 

actions. Within 10 days after February 15,

amend Section IV, Normal Procedures, of the 

following Gulfstream airplane flight manuals 

(AFMs): Model 1125 Astra, 25W–1001–1; 

Model Astra SPX, SPX–1001–1; and Model 

G100, G100–1001–1; as applicable; to include 

the following statement. Insertion of copies 

of this AD at the appropriate places of the 

AFMs is acceptable. 

‘‘1. BEFORE ENGINE START: 

(PRE and POST Mod 20052/Gulfstream 

Service Bulletin 100–31–284): 

CABIN DOOR—CLOSED (Physically verify

CABIN DOOR SEAL light—OUT (50% N1 

may be required)’’ 

Note 1: Mod 20052 is equivalent to 

Gulfstream Service Bulletin 100–31–284, 

dated August 17, 2006. 

Note 2: This AD may be accomplished by 

a holder of a Private Pilot’s License. 

New Requirements of This AD 

Actions and Compliance 

(g) Unless already done, for all airplanes 

except airplane serial number 158, do the 

following actions. 

(1) Within 250 flight hours after the 

effective date of this AD: Modify the WACLP 

in accordance with the Accomplishment 

Instructions of the applicable service bulletin 

identified in Table 1 of this AD. 

TABLE 1—MODIFICATION SERVICE

80–5090–31–0001 ... March 1, 2006. 

(2) Within 250 flight hours after the 

effective date of this AD: Change the WACLP 

and MED wiring in accordance with the 

Accomplishment Instructions of Gulfstream 

Service Bulletin 100–31–284, dated August 

17, 2006. 

(3) Within 250 flight hours after the 

effective date of this AD: Change the wiring 

harness connecting the MED to the WACLP 

in accordance with the Accomplishment 

Instructions of Gulfstream Service Bulletin 

100–31–284, dated August 17, 2006. 

(4) Within 250 flight hours after the 

effective date of this AD: Verify that the Log 

of Modification of the relevant airplane flight 

manual (AFM) includes reference to MOD 

G1–20052, and, if no reference is found, 

revise the Log of Modification of the AFM to 

include reference to the modification. 

(5) Doing the modifications in paragraphs 

(g)(1), (g)(2), (g)(3), and (g)(4) of this AD 

terminates the requirements of paragraph (f) 

of this AD, and after the modifications have 

been done, the AFM limitation required by 

paragraph (f) of this AD may be removed 

from the AFM. 

FAA AD Differences 

Note 3: This AD differs from the MCAI 

and/or service information as follows: 

Paragraph (g)(5) of this AD mandates a 

terminating action. However, Israeli AD 31– 

06–11–05, dated May 27, 2009, does not 

explicitly mandate a terminating action. This 

difference has been coordinated with the 

Civil Aviation Authority of Israel. 

Other FAA AD Provisions 

(h) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, Transport Airplane 

Directorate, FAA, has the authority to 

approve AMOCs for this AD, if requested 

using the procedures found in 14 CFR 39.19.

227–2677; fax (425) 227–1149. Before using 

any approved AMOC on any airplane to 

which the AMOC applies, notify your 

principal maintenance inspector (PMI) or 

principal avionics inspector (PAI), as 

appropriate, or lacking a principal inspector, 

your local Flight Standards District Office. 

The AMOC approval letter must specifically 

reference this AD. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, under the 

provisions of the Paperwork Reduction Act 

(44 U.S.C. 3501 et seq.), the Office of 

Management and Budget (OMB) has
