AD NUMBER: 2004-07-21 MANUFACTURER: Gulfstream SUBJECT: Airworthiness Directive 2004-07-21 SUMMARY: This amendment adopts a new airworthiness
directive (AD), applicable to certain Model Astra SPX and 1125
Westwind Astra series airplanes, that requires detailed inspections
and resistance measurements of the starter generator electrical
cables of both engines to detect damage, and replacement of the
electrical cable and cable support if any damage is found. This
amendment also requires eventual replacement of the cable support.
This action is necessary to prevent chafing of the starter
generator cable, which could result in electrical arcing in the
vicinity of a fuel line, and possible fire or explosion. This
action is intended to address the identified unsafe condition.
