The Federal Bureau of Investigation is looking into a hole possibly caused by a bullet discovered Monday in the fuselage of a US Airways Group Inc.  plane in a pre-flight inspection at an airport in Charlotte, N.C., Bloomberg News reported Tuesday on its website, citing the airline.

The hole was found near the tail of the Boeing Co. 737 by a pilot in a pre-flight inspection, according to airline spokeswoman Michelle Mohr. The plane, which was taken out of service, had arrived from Philadelphia.

An FBI spokeswoman said the hole extended from the outer fuselage into the cabin.
