Narrative:
I departed asx runway 02. At approximately 1200 ft AGL all occupants heard a pop sound. The left engine spooled back to approximately 45 percent. I told my first officer that we will be returning back to asx, entered a left downwind advised on 122.80. We landed with a good right engine and with the power lever on #1 at idle. The company sent a replacement plane for the passenger. The next day a replacement engine was installed on the 1ST aircraft. A total of 8 or so 1ST and 2ND stage compressor blades were found damaged. Possible cause - ice broke off fuselage during taxi to hangar earlier in the day and was ingested by the left engine. After ice was melted off of plane, it was taxied back to the pick up point and engine run up was conducted and both engines performed fine. A preflight was conducted and nothing out of the ordinary was noted. After the above departure was performed and a return for landing was made a more closer visual inspection was made and only slight inclusions were visible on a 1ST stage compressor blade. The original plan was to tow the plane into the hangar, but because of the 2000 or so foot distance to the hangar and the type of tug to be used, the tug operator did not feel that sufficient traction was available and did not want to be responsible so he asked me to taxi the plane to the hangar. I broke off all the ice on the leading edge of the wings, inspected the engine nacelles, inlets, etc, and then taxied to the hangar.

Title: ACFT EQUIP PROB - FLC RETURNS AND LANDS WHEN THE L ENG INDICATES SERIOUS DAMAGE.
Narrative: I DEPARTED ASX RWY 02. AT APPROX 1200 FT AGL ALL OCCUPANTS HEARD A POP SOUND. THE L ENG SPOOLED BACK TO APPROX 45 PERCENT. I TOLD MY FO THAT WE WILL BE RETURNING BACK TO ASX, ENTERED A L DOWNWIND ADVISED ON 122.80. WE LANDED WITH A GOOD R ENG AND WITH THE PWR LEVER ON #1 AT IDLE. THE COMPANY SENT A REPLACEMENT PLANE FOR THE PAX. THE NEXT DAY A REPLACEMENT ENG WAS INSTALLED ON THE 1ST ACFT. A TOTAL OF 8 OR SO 1ST AND 2ND STAGE COMPRESSOR BLADES WERE FOUND DAMAGED. POSSIBLE CAUSE - ICE BROKE OFF FUSELAGE DURING TAXI TO HANGAR EARLIER IN THE DAY AND WAS INGESTED BY THE L ENG. AFTER ICE WAS MELTED OFF OF PLANE, IT WAS TAXIED BACK TO THE PICK UP POINT AND ENG RUN UP WAS CONDUCTED AND BOTH ENGS PERFORMED FINE. A PREFLT WAS CONDUCTED AND NOTHING OUT OF THE ORDINARY WAS NOTED. AFTER THE ABOVE DEP WAS PERFORMED AND A RETURN FOR LNDG WAS MADE A MORE CLOSER VISUAL INSPECTION WAS MADE AND ONLY SLIGHT INCLUSIONS WERE VISIBLE ON A 1ST STAGE COMPRESSOR BLADE. THE ORIGINAL PLAN WAS TO TOW THE PLANE INTO THE HANGAR, BUT BECAUSE OF THE 2000 OR SO FOOT DISTANCE TO THE HANGAR AND THE TYPE OF TUG TO BE USED, THE TUG OPERATOR DID NOT FEEL THAT SUFFICIENT TRACTION WAS AVAILABLE AND DID NOT WANT TO BE RESPONSIBLE SO HE ASKED ME TO TAXI THE PLANE TO THE HANGAR. I BROKE OFF ALL THE ICE ON THE LEADING EDGE OF THE WINGS, INSPECTED THE ENG NACELLES, INLETS, ETC, AND THEN TAXIED TO THE HANGAR.
