American Airlines grounded 14 Boeing 737-800s. These are planes that have undergone the ‘Oasis’ modification – to replace interiors with more seats; less comfortable seats; less distance between seats; less recline; no seat back video; and smaller lavatories plus bigger overhead bins.
All of the planes were modified by the same vendor, Aviation Technical Services. There were several problems identified with some aircraft including the way that overhead bins attached to the aircraft, and how wiring was done that raises potential safety concerns.
