2008-08-19 Gulfstream Aerospace LP (Formerly Israel Aircraft Industries, Ltd.): Amendment 39-15473. Docket No. FAA-2008-0120; Directorate Identifier 2007-NM-327-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective May 27, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Gulfstream Model Gulfstream G150 airplanes, certificated in any category, serial numbers 201 through 239 inclusive.
Subject
(d) Air Transport Association (ATA) of America Code 24: Electrical power.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:
Possible chafing between [the] electrical feeder cable connected to contactor 123P/2 and ground point 803GND, installed within the left DC power box, discovered during routine receiving inspection. This condition may exist on boxes installed on in-service aircraft. If this chafing condition is left unattended, an electrical short may develop, leading to disconnection of the battery and battery bus from the electrical system of the aircraft, [which could result in] overheating, arcing, smoke and fire.
The corrective action includes inspecting for chafing and arcing damage of the feeder cable, terminal lug and ground point, contacting Gulfstream for repair if any damage is found and repairing, installing new heat-shrink tubing if the tubing is missing or damaged, and repositioning the feeder cable.
Actions and Compliance
(f) Unless already done, do the following actions. Within 50 flight hours or 30 days after the effective date of this AD, whichever occurs first, inspect the feeder cable, terminal lug 123P/ 2, and ground point 803GND for chafing and arcing damage, reposition the feeder cable to maintain an adequate gap, and do all applicable corrective actions. Do the actions in accordance with Gulfstream Alert Service Bulletin 150-24A-046, dated October 31, 2007. Do all applicable corrective actions before further flight.
