INSTALLATION MANUAL
10) Engine suspension and position
■ CAUTION: At installation of engine be aware of engine weight and assure careful
handling.
The engine suspension is determined essentially by the aircraft design. Twelve
attachment points are provided on the engine (8 on engine and 4 on engine frame).
The engine can be supplied with a well tried and certified suspension frame for
attachment on the fire proof bulk head. The airbox is supported on this frame too. The
installation into the aircraft is as generally practised by captive rubber mounts which
ensure also to balance out vibrations and sound from engine to aircraft frame.
▲ WARNING: If the engine suspension frame supplied by BRP-Powertrain is not
used or if modified, certification to the latest requirements such as
FAR or EASA has to be conducted by the aircraft manufacturer.
It is recommended to use the ROTAX engine suspension frame and the 4 stated
attachment points R2, L2, R3 and L3 .
▲ WARNING: At least 4 of the given anchorage points must be used in a side
symmetrical pattern of the left (L) and right (R) side.
