Airlines in the booming Asia-Pacific market, are becoming far more aware of life-cycle costs and are seeking more flight-hour-based, comprehensive solutions, extending to spares accessibility and obsolescence management. “The more mature carriers are starting to understand that back shops are not delivering a high-value proposition, and are moving toward outsourcing,” says Bob Still, general manager of operations for Rockwell Collins Melbourne (Australia) Service Center.

When an Air New Zealand Boeing 777-300ER completed a Los Angeles-Auckland flight in December, it was the first time an airline operated under 240-min. extended operations (ETOPS). But the new 240-min. limit is no longer the edge of the envelope—330 min. is now poised to become the new ETOPS gold standard—ever since last November when Boeing received type design authority from the FAA to offer a 330-min. ETOPS “option” on the General Electric GE90-powered 777 family.

When approving ETOPS extensions, the reliability of the propulsion system is the primary focus of the regulators. Central to that is the demonstrated engine inflight shut-down rate (IFSD), which must not exceed specific thresholds.
