Compliance required within the next 25 hours time in service after the effective date of this Airworthiness Directive, and at each subsequent installation of the subject Fuel Injectors.

To detect defective diaphragm assemblies, Bendix P/N 2529470, in Bendix Fuel Injectors, accomplish the following:

a) Determine from the airplane and engine logbooks whether the fuel injector has been repaired and/or overhauled between September 30, 1972, and February 28, 1973. If it is established that the fuel injector has not been repaired and/or overhauled between September 30, 1972, and February 28, 1973 record compliance with Paragraph "a" of this Airworthiness Directive in the engine logbook.

b) If the fuel injector has been repaired and/or overhauled between September 30, 1972, and February 28, 1973, unless already accomplished, inspect the fuel injector in accordance with Bendix Service Bulletin No. RS-41 dated February 13, 1973, Bendix Service Bulletin No. RS-41 revised April 7, 1973, or subsequent FAA approved revisions; or by any other method approved by the Chief, Engineering and Manufacturing Branch, Great Lakes Region. Indicate compliance on airworthy parts by stamping a "T" after the fuel injector serial number, and record compliance in the engine logbook or return to service statement. Replace or repair fuel injectors having defective diaphragms with airworthy fuel injector units.

NOTE: Only appropriately rated FAA approved repair stations are authorized to perform the inspection in "b" above.

This amendment is effective May 16, 1973.
