FAA Mandates Inspections for Pratt & Whitney Engines

## Summary

If you own or operate Pratt & Whitney Canada PW210A, PW210A1, or PW210S engines, listen up! The FAA found cracks caused by heat stress and now requires regular checks and possible part replacements to keep flights safe. These new rules kick in July 14, 2026, so get ready to inspect or replace parts soon—ignoring this could cost time and money down the line.

## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Pratt & Whitney Canada Corp. (P&WC) Model PW210A, PW210A1, and PW210S engines. This AD was prompted by reports of circumferential cracks found at the turbine exhaust frame external surface caused by thermal stress from engine starts. This AD requires repetitive visual inspections of the turbine exhaust frame for cracks and, depending on the results of the inspections, replacement of the turbine exhaust frame. The FAA is issuing this AD to address the unsafe condition on these products.

## Effects PRIA read

- Required inspections and part replacements: cost, high. If you own or operate Pratt & Whitney Canada Model PW210A, PW210A1, or PW210S engines, the FAA now requires repetitive visual inspections of the turbine exhaust frame for cracks and replacement of the frame if cracks are found. This rule is effective July 14, 2026 and follows the procedures in Tran…
- Urgent initial inspection window: cost, medium. For certain helicopters with the affected engines, the AD requires initial compliance within 5 hours time-in-service or 20 engine starts, whichever occurs first, after the AD becomes effective. That means you may need to inspect engines right away after July 14, 2026.
- Estimated compliance and replacement costs: cost, high. The FAA estimates this AD affects 48 engines on U.S. registry. The FAA estimates a visual inspection costs 0.5 work-hours (0.5 x $85 = $42.50) per engine and totals $2,040 for U.S. operators; if a turbine exhaust frame must be replaced, the FAA estimates labor at 9 work-hours ($765) plus parts at $…
- No requirement to report to manufacturer: benefit, low. Although the referenced service material asks operators to submit certain information to the manufacturer, this FAA AD does not require submitting that information. You do not have to send those reports to the manufacturer to comply with this AD.
- How an 'engine start' is counted: cost, low. The AD defines an 'engine start' to include any engine start for any reason, even if it is not followed by a flight. That definition is used to count the 20 engine starts compliance threshold where applicable.
