Federal Aviation Administration (FAA), Department of Transportation (DOT).
Final rule; request for comments.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The unsafe condition is incomplete closure of the main entry door, which may result in the door opening in flight, causing damage to wing, fuselage, engine, and/or tail, and possible damage to the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
This AD becomes effective February 15, 2007.
We must receive comments on this AD by March 2, 2007.
You may send comments by any of the following methods:

Streamlined Issuance of AD
The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. This streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products. Start Printed Page 4415
This AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The AD contains text copied from the MCAI and for this reason might not follow our plain language principles.
The Civil Aviation Authority of Israel (CAAI), which is the aviation authority for Israel, has issued Israeli Airworthiness Directive 52-06-11-08, dated November 28, 2006 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The unsafe condition is incomplete closure of the main entry door, which may result in the door opening in flight, causing damage to wing, fuselage, engine, and/or tail, and possible damage to the airplane. The MCAI requires amending the airplane flight manuals to include additional procedures for verifying complete closure and locking of the main entry door. You may obtain further information by examining the MCAI in the AD docket.
FAA's Determination and Requirements of This 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, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all the information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
Differences Between the 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 required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are described in a separate paragraph of the AD. These requirements take precedence over the actions copied from the MCAI.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because there have been two incidents of main entry doors opening in flight, both at relatively low altitude and airspeeds. Since it cannot be shown the airplane can continue safe operation and return to the nearest airport after such an event in any phase of flight, we have determined that loss of an airplane is possible unless immediate actions are taken. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.
This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2007-27077; Directorate Identifier 2006-NM-286-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.
We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about 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.
We determined that this AD would not have federalism implications under Executive Order 13132. This 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 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 AD and placed it in the AD docket.Start List of Subjects

The mandatory continuing airworthiness information (MCAI) requires amending the airplane flight manuals to include additional procedures for verifying complete closure and locking of the main entry door.
Actions and Compliance
(e) Unless already done, do the following actions. Within 10 days after the effective date of this AD, 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 door latch handle pin is fully engaged in the handle lock).
2. BEFORE TAXIING: Change the CABIN DOOR procedure as follows (POST Mod 20052/Gulfstream Service Bulletin 100-31-284): Check CABIN DOOR light—OUT.
3. BEFORE TAKE-OFF: Insert between the POSITION lights switch and the THRUST LEVERS procedures: (PRE Mod 20052/Gulfstream Service Bulletin 100-31-284): Check CABIN DOOR light—OUT (50% N1 may be required).
(POST Mod 20052/Gulfstream Service Bulletin 100-31-284): Check CABIN DOOR light—OUT; CABIN DOOR SEAL light—OUT (50% N1 may be required).”
Mod 20052 is equivalent to Gulfstream Service Bulletin 100-31-284, dated August 17, 2006.
This AD may be accomplished by a holder of a Private Pilot's License.
FAA AD Differences
This AD differs from the MCAI and/or service information as follows: We revised the order in which the AFM procedures for verifying closure and locking of the main entry door appear in the MCAI. We also removed one procedure under “BEFORE TAXIING” for verifying the cabin door seal light is out (Post Mod 20052/Post Gulfstream Service Bulletin 100-31-284) and for verifying the cabin door light is out (Pre Mod 20052/Pre Gulfstream Service Bulletin 100-31-284).
