Germany's BFU released their brief final report reporting the cause of the serious incident was:
A leaky valve at the bulk seal at the keel beam of the APU bleed duct was identified as reason for the depressurisation.
Another leakage was found in the area of the left-hand pack.
The BFU reported: "Both Cabin Pressure Controllers (CPC) were read out. Both had recorded the error High Cabin Air Leak Rate. One condition for this error being recorded is that the cabin pressure rate was more than 2,000 SLFPM (sea level feet per minute). After the irregularities had been eliminated a cabin pressure test was conducted which revealed leakage at the left-hand pack. After the left-hand pack had been closed down the leak tightness of the pressurized cabin was established and the aircraft cleared for service in accordance with the Minimum Equipment List (MEL) for a flight without passengers up to FL250."
