Before further flight after the effective date of this AD, inspect each of the two Edison P/N 195-10TC112D1 fuel pressure indicators for a ruptured diaphragm by disconnecting and observing the fuel pressure gage vent line while operating the appropriate electric fuel pump. If fuel is found in the vent line or flows from vent, replace gage.

2. Within the next 25 hours time in service after the effective date of this AD, install fuel float check valves, Aerostar Part Number A6601151, in accordance with instruction 11 of Aerostar Aircraft Corporation Service Bulletin No. 600-28, dated November 4, 1970, or later FAA approved revision. Alternate means of compliance or equivalent replacement parts may be acceptable if approved by the Chief, Engineering and Manufacturing Branch, Flight Standards Division, Southwest Region, Federal Aviation Administration, Fort Worth, Texas.

This amendment becomes effective to all known owners of Aerostar Model 600 and 601 airplanes upon receipt of individual copies mailed November 6, 1970, and to all other persons on November 16, 1970.
