Narrative:
On nov/xa/97 I was captain on a flight from pit to mem. The flight was delayed for approximately 50 mins due to freezing rain. When the rain stopped, we were deiced and anti-iced with type I and type ii fluid. During taxi, light freezing rain returned and at XA35L we took off runway 14 pit well within holdover time. Temperature was 0 degrees C, light freezing rain, engine anti-ice open. Engines were stable throughout the takeoff and initial climb, but #1 engine failed at 1500 ft AGL while power was being reduced for noise abatement. ATC vectored us for an uneventful ILS to runway 10L pit. Maintenance discovered metal in the tail section of #1 engine. Upon further investigation there appeared to be a contained failure on the N2 turbine. The failure was limited to this section of the engine and was not WX related.

Title: AN ACR LGT FREIGHTER FLC LOSE THE #1 ENG WHILE REDUCING PWR FOR NOISE ABATEMENT PURPOSES AFTER TKOF. THE FLC DECLARED AN EMER AND RETURNED TO LAND WHERE THEY DISCOVERED THAT THE ENG HAD A CONTAINED N2 TURBINE FAILURE.
Narrative: ON NOV/XA/97 I WAS CAPT ON A FLT FROM PIT TO MEM. THE FLT WAS DELAYED FOR APPROX 50 MINS DUE TO FREEZING RAIN. WHEN THE RAIN STOPPED, WE WERE DEICED AND ANTI-ICED WITH TYPE I AND TYPE II FLUID. DURING TAXI, LIGHT FREEZING RAIN RETURNED AND AT XA35L WE TOOK OFF RWY 14 PIT WELL WITHIN HOLDOVER TIME. TEMP WAS 0 DEGS C, LIGHT FREEZING RAIN, ENG ANTI-ICE OPEN. ENGS WERE STABLE THROUGHOUT THE TKOF AND INITIAL CLB, BUT #1 ENG FAILED AT 1500 FT AGL WHILE PWR WAS BEING REDUCED FOR NOISE ABATEMENT. ATC VECTORED US FOR AN UNEVENTFUL ILS TO RWY 10L PIT. MAINT DISCOVERED METAL IN THE TAIL SECTION OF #1 ENG. UPON FURTHER INVESTIGATION THERE APPEARED TO BE A CONTAINED FAILURE ON THE N2 TURBINE. THE FAILURE WAS LIMITED TO THIS SECTION OF THE ENG AND WAS NOT WX RELATED.
