Federal Aviation Administration FAA, DOT.
ACTION: Final rule.
AGENCY:

The FAA is adopting a new airworthiness directive AD for all Pratt & Whitney Canada Corp. P&WC
PW210A and PW210S model turboshaft engines. This 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 high-pressure compressor HPC rotor.

is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective September 9, 2021.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD
as of September 9, 2021.
