Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes. This proposed AD was prompted by a report that torque wrenches used during production installation of bulkhead fittings on the oxygen lines of the flight crew oxygen mask stowage boxes and adapter fitting on the oxygen pressure gauge were out of calibration during production installation, which resulted in a higher torque level setting than required. This proposed AD would require replacement of the affected oxygen line fittings, as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
