REGULATORY TEXT:   77-13-01 GRUMMAN AMERICAN AVIATION CORPORATION (GAAC): Amendment 39-2919 as amended by Amendment 39-3003 is further amended by Amendment 39-3183. Applies to GAAC Model G-159, all serial numbers, and Model G-1159, serial numbers 1 through 208 and 775, airplanes certificated in all categories.

Compliance required within 10 hours time in service after June 21, 1977, unless already accomplished.

To prevent injury to an occupant of any jumpseat located between fuselage stations 119 and 169 on GAAC Models G-159 and G-1159 airplanes, accomplish one of the following:

(a) Install a placard either on the bulkhead adjacent to the jumpseat or at any equivalent location approved by the Federal Aviation Administration utilizing a minimum of 3/16 inch high letters with the wording: "JUMPSEAT OCCUPANCY DURING TAXI, TAKEOFF, OR LANDING PROHIBITED." or

(b) Modify in the following manner:

1. The Model G-159 nose landing gear drag strut fused or bulkhead modification in accordance with GAAC Aircraft Service Change No. 226, Part I or II, or later FAA approved revision, or in an equivalent manner approved by the Chief, Engineering and Manufacturing Branch, FAA, Southern Region.

2. The Model G-1159 nose landing gear wheel well bulkhead is modified to eliminate drag strut penetration in accordance with GAAC Aircraft Service Change No. 226, Part II, or later FAA approved revision, or in an equivalent manner approved by the Chief, Engineering and Manufacturing Branch, FAA, Southern Region, or

(c) Upon a grant of extension of compliance time by the Chief, Engineering and Manufacturing Branch, FAA, Southern Region, the required placard may be removed for the length of the extension. Interested operators must furnish documentation with justification for the need for an extension to the Federal Aviation Administration, Chief, Engineering and Manufacturing Branch, P.O. Box 20636, Atlanta, Georgia 30320 by July 21, 1978. Also required in this documentation is evidence of a firm commitment from GAAC or a qualified modifier on the available date for the modification kit for that serial number aircraft. Each request for an extension will be handled on an individual aircraft basis.

When either of the modifications described in paragraph b(1) or b(2) are accomplished, or the individual grant of extension is issued in accordance with paragraph (c), the required placard of paragraph (a) may be removed. However, grants of extension of compliance time will not be issued for any date beyond November 8, 1979. After November 8, any G-159 or G-1159 aircraft with a jumpseat installed between fuselage stations 119 and 169 must have installed either the modification in paragraph b(1) or b(2), or the placard in paragraph (a).

Amendment 39-2919 became effective June 21, 1977.
Amendment 39-3003 became effective August 8, 1977.
This Amendment 39-3183 becomes effective April 21, 1978.
