American Airlines celebrates excellence in aviation maintenance with top mechanics

American Airlines recognized five of its top aviation maintenance technicians (AMTs) for their exceptional work in their field as recipients of this year’s Ken MacTiernan Excellence in Aviation Maintenance Award. Since 2019, the award has been honoring AMTs at American who exhibit the qualities of professional AMTs, strive to uphold the highest standards in aircraft maintenance and support and promote the profession.
