b. At the next annual inspection, or within the next 100 hours' time in service, whichever comes first after the effective date of this AD, install Aerostar Kit No. SB 600-23-1 in accordance with Aerostar Service Bulletin No. 600-23, dated November 4, 1970, or by an equivalent method approved by the Chief, Engineering and Manufacturing Branch, Southwest Region, FAA, Fort Worth, Texas.

c. When the modification has been incorporated, the placard required by paragraph (a) above may be removed.
