2) Engine suspension and installation position
General note
Engine suspen-
sion
The engine suspension is essentially determined by the aircraft design.
Eight attachment points are provided (4 on engine and 4 on engine frame).
Engine suspen-
sion frame
The engine is supplied with a tested and certified suspension frame for the
fireproof bulk head. Installation in the aircraft is carried out using standard
captive rubber mounts which also isolate vibration and noise from the air-
craft frame.
2.1) Engine suspension instructions
General note
Noise emmision
and vibration
During engine installation take into account the total
engine weight and ensure careful handling.
If the engine suspension frame is not used or if modi-
fied, certification in accordance with the latest regula-
tions, such as FAR or EASA, must be conducted by the
aircraft manufacturer.
The rubber mounts for neutralising vibrations and all
engine suspension components not in the scope of de-
livery must be ground run tested at the specified loads
and tested for vibration behaviour.
Certification to the latest regulations, such as FAR and
EASA, must be conducted by the aircraft manufactur-
er.
The engine suspension must be designed to prevent
excessive engine movement and to minimise noise
emission and vibration on the airframe.
If the GENUINE-ROTAX engine suspension frame is
not being used, a vibration test must be carried out.
