1. PLANNING INFORMATION 
A. EFFECTIVITY 
NOTE 
For AW119MKII helicopters equipped with STC 
SR03280NY “Installation of a Garmin G1000H 
PFD/MFD Display System” contact the STC holder. 
Part I : all A119/AW119MKII (not equipped with retrofit kit battery relocation P/N 
109G2406R01) helicopters from S/N 14031 thru 14900. 
Part II: all A119 helicopters from S/N 14003 thru 14030. 
Part III: all AW119MKII helicopters up to S/N 14900 equipped with retrofit kit battery 
relocation P/N 109G2406R01. 
Part IV: all AW119MKII helicopters from S/N 14901 and subsequent. 
B. COMPLIANCE 
Within and not later than 12 months after the issue of this Service Bulletin.  
C. CONCURRENT REQUIREMENTS 
N.A. 
D. REASON 
A case of undetected electrical failure and consequent loss of electrical power supply 
t
o all buses occurred on an AW119MKII helicopter. The investigation allowed to 
determine that the occurrence experienced was due to a series of events: the rupture 
of the drive shaft of the starter generator that was then unable to provide the necessary 
electrical power coupled with the lack of the Battery Discharge Detector, a device 
capable to alert the crew when the battery is providing electrical power to the helicopter 
in lieu of the starter generator itself. The investigation performed, allowed to identify the 
root cause of the drive shaft failure in a misalignment of the starter generator drive 
shaft, most probably occurred during installation/removal operations. As a containment 
action, Leonardo Helicopters issued the Alert SB 119-121 providing more robust 
instructions on the removal and the installation of the component, in compliance with 
latest data available from the supplier. 
As a terminating action, in order to allow the timely detection of the Drive shaft failure, 
LHD issued this SB to retrofit the affected A119 fleet with the Retromod Kit Battery 
Discharge Installation P/N 109G2430R02.

1.2 SAFETY 
A) Ensure that power is removed from any LRU, test equipment or powered assembly before
t
he connection or disconnection of electrical wiring.
B) In the interests of safety to personnel and to protect aircraft components and structure, it is
recommended that pro e used for initial testing. The short circuitduction batteries not b
destructive difficulty of maintaining a reliable state ofpower of batteries coupled with the 
charge poses problems in a production test . For these reasons, thenvironment e use of
regulated and current limited DC power supplies is recommended in place of the Ground
Power Unit and the Batt  voltage and safe source of DCery. This will provide a controllable
power until the electrica  System ha ed and productionl Distribution s been satisfactorily test
batteries and normal ground power can be connected.
C) Secure and/or insulate any un-terminated power wiring prior to application of power.
