2. Total Loss of Oil Pressure
If a total loss of oil pressure is accompanied by a rise in
oil temperature, this is a good indication that engine
failure is imminent. Proceed as follows:
a. Reduce engine power immediately.
b. Select a suitable forced landing field and land with
power.
3-7. Turbocharger or Wastegate Failure
Turbocharger or wastegate seizure will be evidenced by loss
of manifold pressure, if operating at manifold pressures
above ambient pressure. It should be possible to maintain
level flight at reduced airspeeds and altitudes as the engine
should be capable of maintaining manifold pressure equal
to ambient pressure. If the wastegate seizes, it may take
considerable force on the throttle twist grip to separate the
linkage between the throttle and the wastegate. If the
turbocharger seizes or the wastegate seizes in the full
bypass condition, proceed as follows:
1. Perform a power check to confirm power available for
landing.
2. Land as soon as practicable, using running landing
(reference Section 4, para. 4-18).
