Operated by the Air Charter Safety Foundation, the Illegal Charter Reporting Hotline is open to employees or agents of FAR Part 135 on-demand certificate holders and the general public to file reports of suspected illegal commercial flights, “where an aircraft operator without a Part 135 certificate is accepting compensation for transportation in violation of both FAA and Department of Transportation regulations.” The toll-free hotline, (888) 759-3581, is staffed by an independent third party with knowledge of the air charter industry. Reports can be filed anonymously if desired, and all reporters will be provided with a case code for follow-up. The FAA will be provided with details to initiate an investigation, and the National Air Transportation Association will regularly contact the FAA to ensure that cases are being followed up for appropriate action.
