Airworthiness Directives; Pratt &
Whitney Canada Corp. Turboshaft Engines Federal Aviation Administration FAA, DOT.
ACTION: Notice of proposed rulemaking NPRM.
AGENCY:

The FAA proposes to adopt a new airworthiness directive AD for all Pratt & Whitney Canada Corp. P&WC
PW210A and PW210S model turboshaft engines. This proposed AD was prompted by a report from the manufacturer that the Automated Damage Tracking System ADTS may under-count the number of cycles accrued by the impeller and the highpressure compressor HPC rotor. The impeller and HPC rotor are both lifelimited components and exceeding their published life limits could result in the failure of these components. This proposed AD would require the use of the manual low-cycle fatigue LCF
counting method in place of the ADTS
counting method to determine the number of cycles accrued by the impeller and HPC rotor. The FAA is proposing this AD to address the unsafe condition on these products.

Background Transport Canada Civil Aviation Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF2020
13, dated April 28, 2020 referred to after this as the MCAI, to address the unsafe condition on these products. The MCAI states:
The engine manufacturer has discovered that the Automated Damage Tracking System ADTS may under-count the number of cycles accrued by the impeller and the High Pressure HP compressor rotor. The impeller and HP compressor rotor are both life limited components and exceeding their published life limits could result in the failure of these components.
Failure of the impeller or HP compressor rotor could result in the uncontained release of the impeller or the HP compressor rotor, and subsequently could result in damage to the engine, damage to the helicopter, and loss of control of the helicopter.
This Transport Canada AD mandates the use of the Manual Low Cycle Fatigue LCF
Counting method to ensure that the impeller and HP compressor rotor do not exceed their published life limits.
