 for the right main gear (S73) and the steel actuator arm.
 4)  Put a steel actuator bar on the uplock sensor switch for
 the right main gear (S74).

 hook.
 (d)  If you used a simulated gear position you must also use a
 simulated air mode:
 CAUTION:_______ CAREFULLY PULL THE TELEFLEX CABLE UNTIL THE AIR MODE
 SENSOR OPERATES.  IF YOU ARE NOT CAREFUL, YOU CAN
 CAUSE DAMAGE TO THE AIR MODE SENSOR TARGET BRACKET.
