2007-03-05 Gulfstream Aerospace LP (Formerly Israel Aircraft Industries, Ltd.): Amendment 39-14916. Docket No. FAA-2007-27077; Directorate Identifier 2006-NM-286-AD. Effective Date (a) This airworthiness directive (AD) becomes effective February 15, 2007. Affected ADs (b) None. Applicability (c) This AD applies to Gulfstream Model Gulfstream 100 airplanes; and Model Astra SPX and 1125 Westwind Astra airplanes; certificated in any category; all serial numbers. Reason (d) 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 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.

FAA AD Differences Note 3: 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).
