2010-2686. Airworthiness Directives; Gulfstream Aerospace LP Model Gulfstream 100 Airplanes, and Model Astra SPX and 1125 Westwind Astra Airplanes
-
Start Preamble
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.

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:Start Printed Page 6158
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.

(c) This AD applies to Gulfstream Aerospace LP Model Gulfstream 100 airplanes; and Model Astra SPX and 1125 Westwind Astra airplanes; certificated in any category; all serial numbers.
Subject
(d) Air Transport Association (ATA) of America Code 31: Instruments.Start Printed Page 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, 2007 (the effective date of AD 2007-03-05), 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):
