Airworthiness Directives; Pratt & Whitney Canada Corp. Engines

The FAA proposes to adopt a new airworthiness directive (AD) for all Pratt & Whitney Canada Corp. (P&WC) Model PW814GA and PW815GA engines. This proposed AD was prompted by the manufacturer revising the airworthiness limitations section (ALS) of the existing airworthiness limitations manual (ALM) to introduce new or more restrictive airworthiness limitations and associated thresholds and intervals for life-limited parts. This proposed AD would require updating the ALS of the existing ALM or instructions for continued airworthiness (ICA) and the existing approved maintenance or inspection program, as applicable, to incorporate new or more restrictive instructions and associated thresholds and intervals for life-limited parts. The FAA is proposing this AD to address the unsafe condition on these products.
