## Discrepancy

FLIGHT 7358 IDA TO SLC, AIR TURNBACK DISCREPANCY: AFTER TAKEOFF ON CLIMBOUT, THE LANDING GEAR WOULD NOT RETRACT NORMALLY. CYCLING THE GEAR HANDLE HAD NO EFFECT. SIMULTANEOUSLY, THE CREW RECEIVED A "DON'T SINK" WARNING (ALTHOUGH THE AIRCRAFT WAS WELL ABOVE ANY TERRAIN) AND INTERMITTENT STICK SHAKER. CREW ELECTED TO RETURN TO IDA, NO EMERGENCY WAS DECLARED. AFTER EXTENSIVE TROUBLESHOOTING MAINTENANCE REPLACED THE LG CONTROL LEVER AND RADIO ALTIMETER TRANSCEIVER. OPS CHECKS GOOD AND OCF WAS SATISFACTORY. PN LG CONTROL LEVER, F96GA0102 SN 124: TRANSCEIVER, 9599-607-14562 SN 4575.
