AD: Pratt & Whitney Canada Corp. Turboshaft Engines

AD NUMBER: 2019-22-03

PRODUCT: Certain Pratt & Whitney Canada Corp. (P&WC) PT6B-37A turboshaft engines.

ACTION: Final rule

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2015-20-04 for the engines listed above.

AD 2015-20-04 required initial and repetitive inspections until replacement of the No. 10 bearing, and eventual replacement of the No. 9 bearing, both located in the engine reduction gearbox (RGB) assembly.

This AD requires removal from service and replacement of the No. 9 and No. 10 position bearings.

This AD was prompted by reports of incorrect engine torque for PT6B-37A turboshaft engines.

DATES: This AD is effective December 24, 2019.

COST: The FAA estimates that this AD affects 119 engines installed on helicopters of U.S. registry. Operators may incur the following costs in order to comply with this AD:

  • Labor: Remove and replace No. 9 and No. 10 bearings: 65 work-hours × $85 per hour = $5,525 per aircraft.
  • Parts: $37,874.
  • Cost per aircraft: $43,399.
