LONDON, July 13 Executives at aircraft engine
maker Pratt & Whitney said a fault on the engines for
Bombardier's CSeries planes was to do with a seal in
the oil system and not to do with the low pressure turbine.
The company, a division of United Technologies Corp,
makes the engine for Bombardier's CSeries narrow-body plane, but
the aircraft has been grounded since late May after a major
engine failure in testing.
"The issue is a seal problem in the oil system. The
fan-drive gear system is rock solid," Pratt Commercial Engines
President David Brantner told journalists at a briefing ahead of
the Farnborough air show.
Bombardier hopes to dominate the 110- to 149-seat plane
market with the CSeries, built with lightweight composite
materials and other technologies designed to reduce fuel burn,
noise and operating costs.
Separately on Sunday, Pratt's Canadian unit signed a deal
for its PWC150C turboprop engine to power the new MA700 regional
turboprop aircraft being launched by AVIC Xi'an Aircraft Company
