temporarily require additional inspections to probe a component
flaw in the powerplant, European safety regulators said.
The European regulator is concerned about degradation of
seals on the Trent 1000’s intermediate pressure turbine section,
and the engines will have to be removed in certain
circumstances, the Cologne, Germany-based European Aviation
Safety Agency said today in an airworthiness directive that
takes effect May 2.
“This condition, if not detected and corrected, could lead
to an in-flight shut-down resulting in reduced control of the
airplane,” EASA said.
Rolls-Royce is one of two engine suppliers on Boeing’s

“We have, as a matter of good practice, recommended that
Trent 1000 operators make a routine engine inspection at a time
convenient to their operations to check for the presence of a
small component piece to ensure optimum engine performance is
maintained,” Rolls-Royce spokesman Richard Hedges said. “All

New engines can be used on up to 450 flights before being
checked and thereafter would need to be examined at least every
200 flights, EASA said. A long-term fix to remove the need for
repeat inspections should be in place in several months, it
