The FAA proposes a $300,000 fine against American Airlines

The Federal Aviation Administration (FAA) (Washington) yesterday (March 18) on proposed a second fine in a week of $300,000 against American Airlines (Dallas/Fort Worth) for alleged maintenance violations according to Reuters.

The FAA alleged American mechanics misdiagnosed a problem with the heater on an McDonnell Douglas DC-9-82 (MD-82) air speed sensor in 2009 that should have restricted when the plane could fly. Instead, the work was deferred and the aircraft flew five regularly scheduled flights before the mistake was corrected.

Last week, the FAA proposed a $787,500 fine against American for three alleged maintenance violations that occurred in 2008 and 2009.
