Unsafe Condition
the occurrence of drill marks at the lower ring region of the rear pressure bulkhead between the circumferential splice joint and rear skin located between stringers 12 and 13. These marks may result in formation of fatigue cracks accelerated by corrosion reducing the structural strength of the rear pressure bulkhead, which may cause a sudden decompression of the passenger cabin.
