REGULATORY TEXT:  
76-11-08 AVIONS MARCEL DASSAULT-BREGUET AVIATION (AMD/BA): Amendment 39-2633. Applies to Model Falcon 10 airplanes, certificated in all categories, which incorporate General Electric (GE) Model 2CM504D1 or 2CM504D1A starter-generators.

Compliance is required as indicated.

To prevent a possible loss of electrical power to the airplane, accomplish the following:

(a) Within the next 10 hours time in service after the effective date of this AD, unless already accomplished within the last 40 hours time in service, and thereafter at intervals not to exceed 50 hours time in service from the last inspection, comply with the following:

(1) Remove the starter-generator, GE Model 2CM504D1, or 2CM504D1A.

(2) Inspect the brushes, and replace them as necessary, in accordance with paragraph 2.B. of GE Service Bulletin No. 2CM504D1/D1A-24-01, dated May 15, 1975, or an FAA-approved equivalent.

(3) Inspect the drive-end bearing for radial play in accordance with the procedures specified in paragraphs 2.A.(1) through 2.A.(4) of the section entitled "Accomplishment Instructions" of GE Service Bulletin No. 2CM504D1/DIA-24-01, dated May 15, 1975, or an FAA-approved equivalent, and determine the average radial play for the three measurements required.

(b) If the average radial play determined in accordance with an inspection specified in paragraph (a)(3) of this AD, exceeds 0.0020 inch (0.051 mm), before further flight, replace the starter-generator, with either -

(1) A serviceable starter-generator GE Model 2CM504D1 or 2CM504D1A or an FAA-approved equivalent part. Prior to installation, inspect the replacement starter- generator in accordance with paragraph (a) of this AD, and, thereafter, continue to inspect in accordance with that paragraph; or

(2) A starter-generator of improved design, GE Model 2CM504D1D, or an FAA-approved equivalent part.

(c) The inspections specified in paragraph (a) of this AD may be discontinued upon the installation of a starter-generator GE Model 2CM504D1D or an FAA-approved equivalent part.

(d) Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Aircraft Certification Staff, FAA, Europe, Africa, and Middle East Region, c/o U.S. Embassy, A.P.O. New York, N.Y. 09667, 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 change for that operator.

This amendment becomes effective June 15, 1976.
