This was said by the Chairman of United Technologies back in 1997:
"We've seen same kinds of gains in basic engine reliability, what we call in-flight shutdowns (IFSD). When we began with high bypass turbofans in the late 1960s, we regularly saw IFSD rates in the forty per 100,000 engine flight hour (EFH) range, or 400 per million EFH, or an expected shutdown of about once per engine per year. Today's ETOPS standard (the long range, over water operation), is one twentieth that rate, 2 IFSDs per 100,000 hours or about one event per engine per twenty years."
Any idea what is happening here, two engines (and their corresponding aircraft) with the same operator in such a short term?
