E8-28270 Airworthiness Directives; Pratt & Whitney PW4000 Series 94-Inch Fan Turbofan Engines Rule The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney (P&W) PW4052, PW4056, PW4060, PW4062, PW4152, PW4156A, PW4158, PW4460, and PW4462 turbofan engines. This AD requires a onetime visual inspection of all EEC-131 model electronic engine controls (EECs). This AD also requires the EECs to be identified, categorized by group number, marked, and replaced using a fleet management plan. This AD results from a report of an uncommanded engine in-flight shutdown due to defective EEC pulse width modulator (PWM) microcircuits. We are issuing this AD to prevent uncommanded in-flight engine shutdowns which could result in loss of thrust and prevent continued safe flight or landing. 2008-12-04 2008 12 https://www.federalregister.gov/documents/2008/12/04/E8-28270/airworthiness-directives-pratt-and-whitney-pw4000-series-94-inch-fan-turbofan-engines https://www.govinfo.gov/content/pkg/FR-2008-12-04/pdf/E8-28270.pdf Transportation Department; Federal Aviation Administration 492,159 The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney (P&W) PW4052, PW4056, PW4060, PW4062, PW4152, PW4156A, PW4158, PW4460, and PW4462 turbofan engines.
