Resumo
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model CL-215-6B11 (CL215T variant) and CL-215- 6B11 (CL415 variant) series airplanes. This proposed AD would require replacing the mounting pad studs of the auxiliary feather pump with new, longer studs, and installing a pressure relief valve. This proposed AD is prompted by a few incidents of external oil leaks from the oil pump of the power control unit due to a malfunction of the pressure regulating valve. We are proposing this AD to prevent fracturing of the pump body, which could result in loss of engine oil, and consequent inability to maintain engine oil pressure and to feather the propeller.
