Washington, Aug 31: The US Federal Aviation Administration has ordered US airlines to inspect 1,440 Boeing jets to see if they have a fuel pump with potentially faulty wiring that could lead to an explosion.

The FAA also said it was warning foreign airlines, which operate about 2,100 of the aircraft with suspect pumps. The FAA stressed that no serious incidents have been linked to problems with the pumps, which are made by Hydro-Aire Inc. of Burbank, California, and were installed in January and April on Boeing 737s, 747s and 757s.


The US airlines were given four days to inspect their fleets. The FAA estimated 1,250 pumps could have a problem with wires that were placed too close to a rotor and can chafe.


The FAA is sending advisories about the pumps to its counterpart agencies in other countries. Ron Wojnar, the FAA's deputy director of aircraft certification services, said any airlines with the pumps are being ordered to keep enough fuel in the tanks to cover the devices even when the planes bank or encounter turbulence in flight.


Wojnar said the submersion would prevent any sparks from igniting fuel vapors. "This is not an unsafe condition," he said.


The order affects 515 of the 737s, 247 of the 747s, and 678 of the 757s operated by US carriers. Bureau Report
