Safety Alert Messages
Ref. ID
Title
1
WARNING
Connection of equipment or devices other than the Lycoming “Field
Service Tool” to CAN 2 Bus may compromise safe EECS operation.
Connection of non-Lycoming approved equipment or devices to the
CAN 2 bus interface is prohibited. The Field Service Tool must not
be used in flight.
2
WARNING
In the event of a NTO indication in flight, the operator should make
minimum and gentle throttle changes to reduce operability
anomalies.
3
WARNING
After a software installation, the maintainer shall confirm proper and
correct software loading via the Lycoming Field Service Tool.
4
WARNING
An ECU reset (re-initialization) shall only be conducted as a last
chance recovery attempt from an EECS anomaly as determined
necessary by the operator. It is possible that an ECU reset may not
be recoverable. The operator must take this into consideration when
deciding to command a reset.
5
WARNING
The NTO indication provides an indication that the ECU along with
limited conventional engine hardware is acceptably safe for flight
once a proper PFT is conducted. The operator must still interrogate
conventional engine indications to determine that the conventional
engine is also acceptable safe for flight.
6
WARNING
The operator must properly conduct a PFT prior to flight.
7
WARNING
The operator must allow sufficient time for the PFT to be completely
executed (as indicated by the PFT active annunciator) prior to
making any throttle changes otherwise the PFT may be inadvertently
canceled with no other indication that the PFT is incomplete.
8
CAUTION
The PFT is not to be commanded during flight. If the PFT is
commanded during flight, throttle movement will cancel the PFT.
9
CAUTION
To ensure proper EECS operation, the Lycoming Field Service Tool
shall not be used during flight.
10
CAUTION
Selection of the IGNITION ON-OFF switch to OFF during ground
operations is a single interlock. To ensure that the engine is not
inadvertently started or the ignition system is not inadvertently
actuated during maintenance, electrical power should be removed
from the ECU during maintenance as a secondary interlock to prevent
injury.
