Transport Canada Recommends EEC Upgrades on Learjet 60s
A Transport Canada safety alert is advising operators of Learjet 60s equipped with older EECs to upgrade the units.

Concerned about an increased rate of in-flight shutdowns (IFSDs) of PW305A engines powering Bombardier Learjet 60s, Transport Canada has issued a civil aviation safety alert (CASA) advising operators to follow Pratt & Whitney Canada service instructions for upgrades to remedy the situation. Released last week, the CASA cites “a notable increase in engine IFSD events” that were attributed to failures of electronic engine control (EEC) units manufactured by Smiths (P/N 31B4741/vendor P/N 1240KDC).
