Narrative:

On takeoff, just as first power reduction was started, #1 strut overheat warning light came on. This was second occurrence for this crew in one day. First occurrence happened at cruise altitude and at a much lower power setting. These differences created an atmosphere of uncertainty. Elected to return and land immediately. Off to on time was 8 minutes. Suggestions: make takeoff power runup to make certain problem is corrected before aircraft is dispatched. Provisions for overweight landing should be part of 'aircraft flight manual' and not obscured in unindexed 'flying information bulletins'. Supplemental information from acn 99112: follow up after the 3RD occurrence revealed a blown pre-cooler on the number one engine. We unknowingly flew around for 2 days with a worsening 250+ degree C bleed air leak.

Title: #1 STRUT OVERHEAT RESULTS IN RETURN TO DEP POINT AND LNDG OVERGROSS.

Narrative: ON TKOF, JUST AS FIRST POWER REDUCTION WAS STARTED, #1 STRUT OVERHEAT WARNING LIGHT CAME ON. THIS WAS SECOND OCCURRENCE FOR THIS CREW IN ONE DAY. FIRST OCCURRENCE HAPPENED AT CRUISE ALT AND AT A MUCH LOWER POWER SETTING. THESE DIFFERENCES CREATED AN ATMOSPHERE OF UNCERTAINTY. ELECTED TO RETURN AND LAND IMMEDIATELY. OFF TO ON TIME WAS 8 MINUTES. SUGGESTIONS: MAKE TKOF POWER RUNUP TO MAKE CERTAIN PROBLEM IS CORRECTED BEFORE ACFT IS DISPATCHED. PROVISIONS FOR OVERWEIGHT LNDG SHOULD BE PART OF 'ACFT FLT MANUAL' AND NOT OBSCURED IN UNINDEXED 'FLYING INFO BULLETINS'. SUPPLEMENTAL INFORMATION FROM ACN 99112: FOLLOW UP AFTER THE 3RD OCCURRENCE REVEALED A BLOWN PRE-COOLER ON THE NUMBER ONE ENGINE. WE UNKNOWINGLY FLEW AROUND FOR 2 DAYS WITH A WORSENING 250+ DEGREE C BLEED AIR LEAK.
