81-04-02 GULFSTREAM AMERICAN CORPORATION: Amendment 39-4035. Applies to all Gulfstream I (G-159) airplanes certificated in all categories.
Compliance is required as indicated, unless already accomplished.
To prevent possible operation at degraded performance levels due to inaccurate performance data presented in the AFM, accomplish the following:
(a) Within 25 hours time in service after the effective date of this AD, incorporate FAA approved Gulfstream I (G-159) Interim Revisions 23-5, dated October 30, 1980, and 23-6, dated November 28, 1980, into the AFM and operate the airplane accordingly.
(b) These interim revisions may be removed from Gulfstream I (G-159) AFM when FAA approved Revision 24 is incorporated.
An equivalent means of compliance may be approved by the Chief, Engineering and Manufacturing Branch, ASO-210, FAA, Southern Region, P.O. Box 20636, Atlanta, Georgia 30320.
This amendment becomes effective February 12, 1981.
