China Southern Airlines says it will consider ahead of schedule checks on its five early model Boeing 737s after the United States Federal Aviation Administration (FAA) ordered emergency inspections of the models' fuel systems. The models affected are the small to medium-sized Boeing 737-100s and 200s. The FAA on Sunday barred all US airlines from using 737 models with more than 50,000 flying hours to carry passengers until inspections were completed and repairs made. The airlines had 14 days to inspect the 737s that had 40,000 flying hours. A China Southern official yesterday said the H share had five Boeing 737-200s, all in its 60 per cent-held Xiamen Airlines, with 20,000 to 30,000 flying hours. The official said the Civil Aviation Administration of China (CAAC) had given no instructions to the company, but Boeing representatives had told them of the fuel problems. Its 737-200 jets, however, all had less than 40,000 flying hours. At the end of March, the Guangzhou-based carrier had 94 aircraft, including 82 Boeings and 10 Airbuses. The H share, however, said it may carry out inspections for safety purposes ahead of regular checks. The FAA called for the inspections after uncovered fuel pump wiring was found in two 737 aircraft. US officials feared the situation could contribute to dangerous wire arcing, possibly causing a fuel tank explosion such as the one that brought down Trans World Airlines Flight 800 off New York in 1996.
