The Canadian Air Force is lifting a
flight restriction on its fleet of 15 CH-149 Cormorant search and
rescue helicopters that temporarily limited the aircraft to search
and rescue operations only, following modifications to an engine
fuel supply line.
The individual CH-149 Cormorant aircraft (Canadian Coast Guard
varient shown below) will be able to be used for training flights
as soon as they are modified.
The flight restriction meant that
the Cormorants could only be flown for actual search and rescue
missions: no training flights could be conducted until aircraft
modifications were completed.
The fuel lines on all 15 Cormorants were inspected and no
further defective lines were found. An over-sized Viton sleeve is
fitted over the aircraft fuel lines to reduce the possibility of
fuel being sprayed inside the engine compartment until new,
re-engineered fuel lines can be produced and installed on all three
engines of the aircraft to completely eliminate the problem.
The recent discovery of two leaking engine fuel lines prompted
Major General Marc Dumais, Commander 1 Canadian Air Division, to
impose the flight restriction as a precautionary measure on Feb. 5.
"The Canadian Air Force will not take unnecessary risks with our
people and equipment. I am satisfied that a proper solution to this
problem is being implemented and that there will be no further
occurrences of leaking fuel lines," said Major-General Dumais.
The engineering solution to the problem was developed by EH
Industries, the aircraft manufacturer. The modifications to the
fuel lines will be carried out by IMP, the aircraft maintenance
