Regulatory Action Targets Sensor Damage In Pratt Engines
The FAA plans to mandate a sensor swap on Pratt & Whitney PW4000-94 engines due to sensor damage caused by epoxy deterioration, which has led to incidents including tailpipe fires and engine shutdowns. The directive, set for publication on May 26, affects 210 US-registered engines and follows Pratt & Whitney’s recommendation to replace the sensors within 10-30 months. This development was first reported by Aviation Week.
