II. Compliance required as indicated.

The inspections outlined in the above Service Bulletin No. 73 must be conducted on all aircraft as follows:

1. Conduct the inspections outlined above in Service Bulletin 73 at maximum intervals of 900 hours and beginning with the last inspection conducted at approximately 1,500 hours total flight time, the succeeding intervals shall not exceed 600 hours.

2. Conduct the inspections of amendments 2and 6 of Service Bulletin 73 between 1,500 and 1,700 total flight hours and at maximum intervals of 200 hours thereafter.

As an added precautionary measure do not operate the aircraft in excess of 90 percent of the Placard Vne and Vno speeds as shown in Aircraft Specification A-795. In the event any turbulence is encountered in flight, immediately reduce the speed to a maximum of 170 m.p.h. and further reduce the speed to a maximum of 150 m.p.h. dependent upon the severity of the turbulence. (Suitable revisions to the operating manual will be provided.)
