FAA Orders Fix for Pratt & Whitney Engine Sensors
Published Date: 5/26/2026
Proposed Rule
Summary
The FAA wants to keep Pratt & Whitney engines safe by fixing a problem with sensors that can cause fires or engine shutdowns. If you own or operate certain PW engines, you’ll need to replace these pressure burner sensors soon. Comments on this plan are open until July 10, 2026, and the fix helps avoid costly and dangerous engine troubles.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Required Pb Sensor Replacement Costs
If you own or operate the listed Pratt & Whitney engines, you must replace the pressure burner (Pb) sensors within the compliance times in the rule. The FAA estimates this affects 210 U.S.-registered engines, with a per-engine cost of $15,864 (2 work-hours at $85/hour = $170 labor plus $15,694 parts) and a total U.S. operator cost of $3,331,440.
Safety Risk Reduction for PW Engines
This AD is meant to stop Pb sensor deterioration that the FAA says has caused tailpipe fires, loss of thrust control, and engine in-flight shutdowns. Replacing the sensors as required helps detect and correct the deterioration and reduce those safety risks for aircraft using the specified Pratt & Whitney engines.
