Hot Section Inspection Cost
A Hot Section Inspection (HSI) is required at mid-life intervals (typically 1,800 hours for PT6A-42) to inspect turbine components for wear and damage. This is less extensive than a full overhaul but critical for continued airworthiness.
HSI Pricing Range:
- Basic HSI (inspection only)$15,000 - $25,000
- HSI with minor repairs$25,000 - $45,000
- HSI with turbine blade replacement$45,000 - $60,000+
HSI intervals depend on engine model and operator profile. Some operators extend HSI intervals through engine condition monitoring (ECM) programs with P&WC approval.

Factory-recommended interval between major overhauls for PT6A-42 engines operated under normal conditions.
