The FAA proposes to supersede Airworthiness Directive (AD) 2017-22-06, which applies to certain Bombardier, Inc., Model CL-600- 2B16 (601-3A, 601-3R, and 604 Variants) airplanes. AD 2017-22-06 requires repetitive inspections for fuel leakage at the engine and auxiliary power unit (APU) fuel pumps, and related investigative and corrective actions if necessary. Since the FAA issued AD 2017-22-06, terminating actions have been developed and additional airplanes have been determined to be affected by the unsafe condition. This proposed AD would retain the requirements of AD 2017-22-06, and require an inspection of the APU, repair if necessary, and modification of the engine electrical fuel pump (EFP) installation. This proposed AD would also add airplanes to the applicability. The FAA is proposing this AD to address the unsafe condition on these products.
