with consequent loss of engine power, particularly at altitude. A signicant loss of manifold
pressure will be indicated and this may be the rst recognisable symptom.
If symptoms of an engine malfunction indicate any possibility of a turbocharger or exhaust
system re the pilot should give immediate consideration to carrying out a precautionary landing
before the situation gets out of hand. If terrain or other operational necessity prohibits such
action the pilot should continue ight at reduced power but remain vigilant for symptoms of a
re developing in the engine bay. Symptoms may include smoke, burning smell, and/or ames.
If an engine bay re is conrmed the Engine Fire In Flight checklist (paragraph 3.3.3) must be
carried out and a forced landing executed.
An exhaust system failure downstream of the turbocharger system will be harder to diagnose in
ight but is also less likely to pose a signicant hazard. Nevertheless if smoke or a burning smell
occurs power should be reduced and the aircraft landed at the rst practical opportunity. If an
engine bay re develops the Engine Fire In Flight checklist (paragraph 3.3.3) must be carried
out and a forced landing executed.
In the event of a partial loss of engine power occurring it is possible that the turbocharger waste
gate control has failed in the OPEN position. Provided no symptoms of rough running or engine
re develop the ight may be continued at reduced power but a landing should be carried at the
rst practical opportunity.
If the turbocharger waste gate control was to fail in the CLOSED position, an engine power over-
boost condition may be experienced. In this case the throttle setting should be reduced as much
as necessary to maintain the manifold pressure within limits.
3.4.3. Forced Landings
If all attempts to restart the engine fail and a forced landing is imminent, a suitable landing area
should be selected and the EMERGENCY LANDING WITHOUT ENGINE POWER checklist
should be completed if at all possible.
3.4.4. Ditching
The aircraft has not been ight tested in actual ditchings, therefore the recommended procedure
is based entirely on the best judgement of the manufacturer.
If available, life jackets should be donned but not inated until after evacuating the aircraft.
Inating the life jackets prematurely increases the risk of damage to them exiting the aircraft.
Additionally their bulkiness adds to the difculty of evacuating the aircraft.
Plan the approach into wind if the winds are high and the seas are heavy. With heavy swells
and light winds, land parallel to the swell. If possible maintain a constant descent rate of
approximately 300 ft/min almost until touchdown but reducing speed to the minimum practical
immediately prior to touchdown. An orderly evacuation of the aircraft should then be conducted.
It may be necessary to open the main cabin sliding door rst to allow the cabin to ood to
equalise the pressure prior to opening the cockpit doors.
3.4.5. Fires
Although engine res are extremely rare in ight, the checklist procedures should be followed if
one is encountered. After completion of this procedure, execute a forced landing. Do not attempt
to restart the engine after an engine re.
