Job Safety Analysis (JSA) and improper compressor purging procedures were brought to the forefront on 8 December with the US Bureau of Safety and Environmental Enforcement’s (BSEE) issuance of Safety Alert No. 327. The alert described two incidents that occurred in the Gulf of Mexico in June and July and the findings of BSEE’s investigations. After the air compressor was back on line, there were two failed attempts to restart the gas compressor. The mechanic then made adjustments to the magnetic pickup and the flywheel. Two attempts later, the gas compressor appeared to be starting, but after 2–3 seconds, the engine backfired.
