Airworthiness Directives; Ipeco Holdings Ltd. Pilot and Co-Pilot Seats
We propose to adopt a new airworthiness directive (AD) for certain Ipeco Holdings Ltd. (Ipeco) pilot and co-pilot seats. This proposed AD was prompted by reports of unexpected movement of pilot and co-pilot seats on takeoff and landing. This proposed AD would require modification and reidentification of the affected seats. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Airbus Defense and Space S.A. (Formerly Known as Construcciones Aeronauticas, S.A.) Airplanes
We propose to supersede Airworthiness Directive (AD) 2013-02- 12, which applies to all EADS CASA (now Airbus Defense and Space S.A.) Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes. AD 2013-02-12 currently requires a one-time inspection to identify the correct polarity for each pair of electrical connectors on each engine fire extinguisher cartridge, and repair if necessary. Since we issued AD 2013-02-12, we have determined it is necessary to add a requirement for modifying the installation of the fire extinguisher circuit harness. This proposed AD would continue to require identifying the correct polarity of each pair of electrical connectors of the affected engine fire extinguisher cartridge, and doing a repair if necessary. This proposed AD would also require modifying the installation of the fire extinguisher circuit harnesses. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turboshaft Engines
We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CT7-8A and CT7-9B model turboshaft engines. This proposed AD was prompted by reports from the manufacturer that the high-pressure compressor (HPC) impeller installed on these engines may have suffered from material degradation during the manufacturing process. This proposed AD would require removal of the affected HPC impellers. We are proposing this AD to address the unsafe condition on these products.
