Procedure; Aircraft; Human Factors
A phone call from someone stating; 'Did you know Aircraft X; Flight XXX has a problem?' Then Air to Ground radio goes off and it was Flight XXX and Controller said; 'I'll call you back.' I thought I was talking to Maintenance Control. Flight XXX; Aircraft X [calling]; 'We had a compressor stall. I'm going to run engines again; OK?' I said; 'Sure; and [I'll] check Maintenance Computer Scepter history.' He; [Flight XXX] called back and said engine parameters are 'OK' and I told him no history on engine in [past] 90-days. 'OK; we will takeoff then.' Never a comment about an aborted takeoff or fire for Flight XXX. The small [Maintenance] room I was in was very busy from Graveyard crew check-in. More than 10-people in a room that measures 15 feet by 20 feet; very crowded. Air to Ground radio very garbled.
Reporter stated there was no mention of flame or fire at any time from the departing flight crew; only their reference to a compressor stall. Since their Maintenance Computer Scepter History did not have any previous Stall data recorded; the flight crew decided to depart.Reporter stated his Supervisor later noted that once a Compressor stall has been confirmed; that a Visual Inspection of the engine is required. A Borescope of the RB-211 Engine was accomplished downline and no discrepancies were found.
A Line Maintenance Lead Technician reports that a B757-300 flight crew took off after reporting a compressor stall during their initial takeoff roll; without returning to the gate for a Visual Inspection of their engines.
