The NTSB asks the FAA to issue an airworthiness directive for Cessna Model T303 airplanes requiring immediate inspections of the turbocharger inlet for exhaust leaks or fire, with remedial action if needed, and removal and inspection of specific fuel metering unit tee fittings (Teledyne Continental Motors part no 646289) for cracks, replacing them with new fittings using proper installation procedures as an alternative.
