Battery system fire
Indication of battery fire is dense smoke and a distinctive chemical smell. Disengage both battery
circuit breakers, land immediately and leave the aircraft as soon as possible.
WARNING! Be aware that lithium battery fires are extremely dangerous because they are
self-sustaining! They are a result of chemical reactions and are impossible to extinguish. You
can only prevent or delay fire propagation by continually cooling down the batteries and sur-
rounding items with a copious amount of water.
Smoke in cockpit
1. Set master switch to OFF.
2. Open all cabin vents for adequate breathing.
3. Land as soon as possible.
EPSI570 failure
While on the ground:
During taxi: Do not takeoff!
During takeoff run: If possible and safe, abort the takeoff procedure!
While in flight:
Without power to the motor: Look for a spot to carry out a safe outlanding. If practical check the
circuit breakers, disengage the system’s four main switches, power lever to cut-off, and attempt a
re-start.
With power to the motor: Do not switch the motor off. Attempt to fly to the next airfield and land
as practical.
Flutter
Flutter is described as the oscillation of control surfaces. In most cases it is caused by abrupt control
deflections at speeds close to or in excess of VNE. As it occurs, the ailerons, elevator or even the whole
aircraft start to vibrate violently.
Should flutter occur, pull on the stick and reduce power immediately!
WARNING! Fluttering of ailerons or tail surfaces may cause permanent structural dam-
age and/or inability to control the aircraft.
After a safe landing, the aircraft MUST undergo a series of check-ups performed by author-
ised service personnel to verify airworthiness.
Exceeding VNE
Should the VNE be exceeded, reduce airspeed slowly and continue flying using gentle control
deflections. Land safely as soon as possible and have the aircraft verified for airworthiness by
authorised service personnel.
