American Airlines- AAE File #EW815504
Pursuant to a recent whistleblower investigation completed on behalf of our office, I wanted you
to know of cultural concerns at American Airlines which have a direct impact on aviation safety.
Six Chicago-based Aviation Maintenance Technicians alleged that maintenance managers had
pressured them to not record discrepancies, take shortcuts with maintenance activities, or
improperly sign-off on work which was not actually completed. Pressuring mechanics in this
way is contrary to regulatory requirements and safe operating practices.
An investigation team from the Orlando Certificate Management Office conducted an exemplary
investigation, interviewing dozens of witresses and gathering hundreds of documents, ultimately
substantiating all of the complainant's allegations. It also appears the concems may be much
more prevalent across American's organtzation than even the complainant's alleged, affecting
maintenance activities in Dallas, New York, Miami and beyond. Additionally, there exists a
substantial likelihood that American has not properly conducted lightning strike inspections for a
protracted period of time.
Flight Standards (AFS) has opened approximately 20 enforcement investigations as a result of
the initial complaint. Although the whistleblower investigation has been completed, we strongly
recommend AFS continue additional investigation to determine the scope, depth, and root causes
If you have any questions, please contact Vincent L. Murray II, Manager and Chief Investigator,
