On the heels of a federal agency's report critical of the FAA's oversight of maintenance and repair stations, a former 20-year FAA airworthiness representative pleaded guilty last week to selling bogus aircraft parts. The court said the sales caused losses of $2.2 million to the FAA and the airlines. Daniel Booker, 63, of California, bought used or surplus parts and falsified the serial numbers, data plates, and documentation to make it appear that the parts met the airlines' specifications, the Associated Press reported. No accidents have been traced to the falsified parts. Booker will be sentenced in January, and could get life in prison.
