Narrative:

After a normal pushback and engine start the captain advanced power for taxi. We were stopped and told an aircraft behind us had rocked up on a wing tip, then were told to continue taxi. A subsequent call to air carrier operations (slc) confirmed that an unoccupied aircraft had received minor damage from our jet blast during initial taxi. From my perspective, I saw nothing abnormal about our power application -- certainly nothing excessive. At no time were we informed of an aircraft behind us after pushback. Corrective actions: 1) push crew should advise of any aircraft behind a taxiing airplane (light or otherwise). 2) a light aircraft parked on a jet operations ramp should be tied down at the very least (the damaged aircraft wasn't).

Title: AFTER PUSHBACK RPTR WAS TOLD ON ADVANCING PWR FOR TAXI THAT AN ACFT BEHIND HAD ROCKED UP ON A WING TIP.

Narrative: AFTER A NORMAL PUSHBACK AND ENG START THE CAPT ADVANCED PWR FOR TAXI. WE WERE STOPPED AND TOLD AN ACFT BEHIND US HAD ROCKED UP ON A WING TIP, THEN WERE TOLD TO CONTINUE TAXI. A SUBSEQUENT CALL TO ACR OPS (SLC) CONFIRMED THAT AN UNOCCUPIED ACFT HAD RECEIVED MINOR DAMAGE FROM OUR JET BLAST DURING INITIAL TAXI. FROM MY PERSPECTIVE, I SAW NOTHING ABNORMAL ABOUT OUR PWR APPLICATION -- CERTAINLY NOTHING EXCESSIVE. AT NO TIME WERE WE INFORMED OF AN ACFT BEHIND US AFTER PUSHBACK. CORRECTIVE ACTIONS: 1) PUSH CREW SHOULD ADVISE OF ANY ACFT BEHIND A TAXIING AIRPLANE (LIGHT OR OTHERWISE). 2) A LIGHT ACFT PARKED ON A JET OPS RAMP SHOULD BE TIED DOWN AT THE VERY LEAST (THE DAMAGED ACFT WASN'T).
