REGULATORY TEXT:  
77-23-04 AVIONS MARCEL DASSAULT-BREGUET AVIATION (AMD-BA): Amendment 39-3075. Applies to Model Falcon 10 airplanes, S/N 1 through 56, certificated in all categories, and any other Model Falcon 10 airplane incorporating Badin Crouzet total-pressure probes, P/N 33790-10.

Compliance is required as indicated.

To prevent failure of total-pressure probe accomplish the following:

(a) Prior to the accumulation of 600 total airplane flights or within the next 100 flights after the effective date of this AD, whichever occurs later, replace both total-pressure probes, P/N 33790-10, with new parts of the same part number, or with probes of improved design, P/N 33790-20, in accordance with paragraph 2 of Falcon 10 Service Bulletin No. F10.34.007, dated July 17, 1975, or an equivalent approved by the Chief, Aircraft Certification Staff for Europe, Africa, and Middle East Region, c/o American Embassy, A.P.O. New York, N.Y. 09667.

(b) Replacement probes P/N 33790-10 are hereby life limited to 600 flights.

(c) For the purpose of this AD, a flight is defined as a single takeoff and landing. If records are not maintained of each takeoff and landing, the number of flights may be determined by dividing each airplane's hours time in service by the operator's fleet average time from takeoff to landing for the airplane type, subject to acceptance by the assigned FAA airworthiness inspector.

This amendment becomes effective December 10, 1977.
