The Civil Aviation Administration of China (CAAC) announced Tuesday that all its airplanes made by McDonnell Douglas (MD) have passed examinations into potential mechanical problems.

The CAAC said all reports from its subordinate airlines which own MD airplanes suggested that all 50 of their MD produced airplanes are in good mechanical condition.

Last Saturday, following a report that an US Alaska Airline registered MD-80 crashed into the Pacific Ocean due to mechanical problems, CAAC ordered all its subordinate companies to conduct

urgent examinations on all MD planes.

Statistics from Boeing China Inc indicate that there are no MD-80 airplanes operating in China.
