All Guimbal Cabri G2 Helicopters.
The CAA has received a report from a maintenance provider of finding a significant crack in the cyclic base on the pilot side (RH) of a Cabri G2 helicopter. Refer to Figure 1 below for further details.
While carrying out Guimbal Mandatory Service Bulletin (MSB) 23-006A, engineers found a crack in the pilot cyclic base P/N G41-42-801 (IPC Ref. IPC4.3-00 Rev C Item 18).
The cracked part was removed from service pending installation of a serviceable replacement.
It is not clear if a specific event, or the aircraft age are contributing factors to the initiation of the crack.
Guimbal MSB 23-006A is not the subject of an Airworthiness Directive but is considered mandatory by the manufacturer. CAA will notify the manufacturer about this finding.
This finding highlights the importance of operators ensuring that they assess and give due consideration to following manufacturer service information.
