Engine Flight Hours—NB -1% in June on Lower CFM56 (-10%) / V2500 (-16%); WB flat on Lower GE90 (-1%)

Industry Update Equity Research

Flight Hours and Daily Utilization by Manufacturer and Engine Type

We are monitoring engine flight activity across the global fleet of passenger and freighter aircraft. We

track both flight hours and average daily utilization by engine type. Total flight hours on an engine type

incorporate both the number of engines in active service along with average utilization. Average daily

utilization measures the daily usage of engines that are in service only (not parked for maintenance/

storage).

We estimate total flight hours in the global fleet were down 1% YoY in June, while ~9% above June

2019 levels, while average daily utilization is at ~8.7 hours, ~5% below June 2019 levels.

Exhibit 2 - Average Daily Utilization for Global NB/WB Fleet (Hours per Day)

We estimate that narrowbody engine flight hours were 1% lower YoY in June and 11% above June

2019 levels, driven primarily by higher GTF/LEAP flight hours (much larger installed base). Widebody

engine flight hours were flat YoY in June and are 4% above June 2019 levels as higher Trent has been

partially offset by lower GE90.
