text:  Mechanic Richard Cuevas, while working for Boeing supplier Spirit Aerosystems, claims he saw holes being drilled into the forward pressure bulkhead, which deviated from Boeing's manufacturing specifications, risking power failure and depressurization in flight. Cuevas says Boeing inspections identified 117 out of 200 holes were improperly drilled, but he claims the company has yet to correct the issue. Boeing responding, saying, engineering analysis determined that the issues raised did not present a safety concern and were addressed.
