79-06-03 GULFSTREAM AMERICAN (formerly Grumman American Aviation Corporation): Amendment 39-3437. Applies to Model G-159, all serial numbers; and to Model G-1159, serial numbers 1 through 238 and 775, certificated in all categories.
Compliance is required prior to further flight, unless already accomplished.
To prevent a potential hazard caused by inability to discharge the engine or APU fire extinguisher bottles, accomplish the following:
(1) Inspect the cartridge terminals on each aircraft engine and APU fire extinguisher bottle (container) for the presence of electrical shunts. Shunts are installed for safety in shipping and handling and inadvertently may have been left installed.
(2) Remove any electrical shunts found on the cartridge terminals, using procedures in the applicable aircraft maintenance manual.
Gulfstream American Alert Customer Bulletins No. 11 for Model G-159, and No. 17 for Model G-1159, both dated February 16, 1979, pertain to this subject.
This amendment is effective April 2, 1979.
