Hot section inspection program

Get the reliability of new OEM engine parts and save through major discounts
We have developed a multi-faceted program to help make your upcoming Host Section Inspection (HSI) on your PT6A engine as smooth as possible. In addition to substantial savings at virtually every stage of your HSI event, you will return to flight with genuine Pratt & Whitney parts installed by our engine experts. Studies have shown that engines maintained by the OEM can often attract a higher asset valuation. So you win two ways.

Benefits of this offer

Upon the purchase of new Compressor Turbine (CT) blades during your HSI event, P&WC will cover the cost of labour for the entire HSI – that’s savings from $15,000 to $20,000 USD depending on your PT6A engine model*. We will also pick up the cost of new CT shroud segments and spark igniters. To give you a head start on your next engine overhaul, we’re offering you a further $10,000 USD credit when you overhaul your engine through one of our P&WCSMART programs.

By leveraging all of the perks of this program, you’ll benefit from up to $40,000 in savings.

As your HSI event progresses you may opt to replace other elements of your engine with our Pratt & Whitney genuine parts. To help with that decision we have developed a second level of discounts:

  • Sealing Ring
