To amend the Federal Aviation Act of 1958 to limit acquisitions of control of air carriers to ensure fitness.

Amends the Federal Aviation Act of 1958 to prohibit a person from acquiring control of an air carrier unless the Secretary of Transportation finds that such acquisition would not result in an increase in the carrier's debt-to-equity ratio to a level greater than one-to-one. Declares that the Secretary may approve an acquisition of control of an air carrier which would result in a debt-to-equity ratio increase to a level greater than one-to-one if the Secretary finds that: (1) such air carrier would continue to be fit, willing, and able following such acquisition; and (2) such acquisition would not be to the detriment of the public interest.
