REGULATORY TEXT:  
76-19-02 AVIONS MARCEL DASSAULT (AMD): Amendment 39-2722. Applies to Model Fan Jet Falcon airplanes, all series, certificated in all categories.

Compliance is required as indicated, unless already accomplished.

To prevent possible contamination of cabin ventilation air with fuel fumes or mist, comply with the following:

(a) Within the next 10 hours time in service or the next 10 days after the effective date of this AD, whichever occurs later, accomplish the following:

(1) Inspect and rectify, as necessary, the fuel tank pressurization system in accordance with Paragraphs (2) and (3) of Fan Jet Falcon (FJF) Maintenance Manual Change Notice Nos. 229 and 230, dated March 1976, or an FAA approved equivalent.

(2) For airplanes incorporating an AMD-installed cabin air conditioning system, inspect and rectify, as necessary, the cabin air conditioning system in accordance with FJF Maintenance Manual Change Notice No. 233, dated March 1976, or an FAA-approved equivalent. For all other airplanes, inspect and rectify the air conditioning system in accordance with a procedure approved by the Chief, Aircraft Certification Staff, Europe, Africa, and Middle East Region.

(3) Incorporate the following operating limitations in the airplane flight manual:

(i) The airplane may not be operated with a feeder tank fuel quantity gage needle in a red zone.

(ii) Takeoff is prohibited if evidence of fuel overflow from drain at fuselage Frame 33, or from the drain mast, is observed.

(iii) If fuel fumes are detected in flight, the airplane may only be flown to the nearest base where repairs can be performed.

(Fan Jet Falcon Flight Manual Revision dated March 17, 1976, deals with the operating limitations specified in paragraph (a)(3)(i) and (ii) of this paragraph. FJF Maintenance Manual Change Notice Nos. 229, 230, and 233 dated March 1976, contain inspection and rectification information for the fuel tank pressurization and air conditioning systems that relate to the deficiencies covered by the operating limitations covered by this paragraph.)

(b) For airplanes not incorporating the fuel tank pressurization system drain provisions of AMD Service Bulletin No. 293, dated January 15, 1968, or an FAA-approved equivalent, within 10 hours time in service after the effective date of this AD replace the placards at the fuel filler opening of each wing tank with new placards that limit the maximum fuel capacity to 1455 kg (3,200 lb).

(c) Within the next 100 hours time in service or 60 days after the effective date of this AD, whichever occurs later, accomplish the following:

(1) Decrease the usable capacity of the fuel feeder tanks in accordance with AMD Service Bulletin No. 554, dated March 18, 1976, or an FAA-approved equivalent. For airplanes serial numbers 1 through 29, incorporate feeder tank float valves, in accordance with AMD Service Bulletin No. 161, Revision 1, dated November 18, 1966, or an FAA-approved equivalent.

(2) Enlarge the diameter of the wing tank pressurization system drain hole in accordance with AMD Service Bulletin No. 555, dated March 18, 1976, or an FAA-approved equivalent. For airplanes serial numbers 1 through 124 incorporate drain hole provisions, in accordance with AMD Service Bulletin No. 293, dated January 15, 1968, or an FAA-approved equivalent.

(d) Prior to the accumulation of 150 hours time in service after accomplishment of paragraph (c) of this AD, and, thereafter, at intervals not to exceed 150 hours time in service since the last inspection, inspect and rectify, as necessary, the fuel overflow drain at fuselage Frame 33, in accordance with FJF Maintenance Manual Change Notice No. 231, subparagraph 3 C, dated March 1976, or an FAA-approved equivalent.

(e) Upon the request of an operator, an FAA maintenance inspector, subject to prior approval of the Regional Director, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for that operator.

This amendment becomes effective September 30, 1976.
