Narrative:

Regular scheduled commercial flight phl-iah. WX at phl was rain and 60 degrees. Normal takeoff. Icing encountered at 8000 ft, #1 nacelle anti-ice switch turned on. Switch agreement light came on but no drop in EPR, so no anti- ice to #1 nacelle. #2 engine and south duct anti-ice switch selected on. Temperature indicator went off scale high and overheat light came on. #2 anti-ice selected off. Climb was made from 10000 ft to 30000 ft in icing with no protection on engine #1 and engine #2. Now, the B727 is a hardy airplane and while the icing was present, no mention was made to return to phl. At 31000 ft we were on top and had no further en route problems. Upon arrival at iah we wrote up both problems and a maintenance delay occurred on the outbound flight. No further report was made.

Narrative: REGULAR SCHEDULED COMMERCIAL FLT PHL-IAH. WX AT PHL WAS RAIN AND 60 DEGS. NORMAL TKOF. ICING ENCOUNTERED AT 8000 FT, #1 NACELLE ANTI-ICE SWITCH TURNED ON. SWITCH AGREEMENT LIGHT CAME ON BUT NO DROP IN EPR, SO NO ANTI- ICE TO #1 NACELLE. #2 ENG AND S DUCT ANTI-ICE SWITCH SELECTED ON. TEMP INDICATOR WENT OFF SCALE HIGH AND OVERHEAT LIGHT CAME ON. #2 ANTI-ICE SELECTED OFF. CLB WAS MADE FROM 10000 FT TO 30000 FT IN ICING WITH NO PROTECTION ON ENG #1 AND ENG #2. NOW, THE B727 IS A HARDY AIRPLANE AND WHILE THE ICING WAS PRESENT, NO MENTION WAS MADE TO RETURN TO PHL. AT 31000 FT WE WERE ON TOP AND HAD NO FURTHER ENRTE PROBS.
