SERVICE BULLETIN

S.B. N°119-130 ALERT DATE: October 5, 2023 Page 2 of 60 REVISION: /

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.

S.B. N°119-130 ALERT DATE: October 5, 2023 REVISION: / Page 3 of 60 The Emergency Procedures related to BATT DISCH and DC GEN reported in the RFMs have been amended accordingly to account for this failure mode, also for AW119MKII G1000H (not with STC SR03280NY) and NXi helicopters, already equipped with the Kit Battery Discharge Detector.

E. DESCRIPTION Part I describes the procedure to perform the installation of the retrofit battery discharge d etector P/N 109G2430R02-101 for the helicopters equipped with IDS and requires to check in cockpit the availability of the last revision of the related RFM.

Part II describes the procedure to perform the installation of the retrofit battery discharge detector P/N 109G2430R02-103 for the helicopters without IDS and requires to check in cockpit the availability of the last revision of the related RFM.

Part III describes the procedure to perform the installation of the retrofit battery discharge detector P/N 109G2430R02-109 for the helicopters with IDS and with battery relocated and requires to check in cockpit the availability of the last revision of the related RFM.

Part IV requires to check in cockpit the availability of the last revision of the related RFM.

F. APPROVAL The technical content of this Service Bulletin is approved under the authority of DOA n

r. EASA.21.J.005. For helicopters registered under other Aviation Authorities, before applying the Service Bulletin, applicable Aviation Authority approval must be checked with Local Aviation Authority.

EASA states mandatory compliance with inspections, modifications or technical directives and related time of compliance by means of relevant Airworthiness Directives.

If an aircraft listed in the effectivity embodies a modification or repair not LHD certified and affecting the content of this Service Bulletin, it is responsibility of the Owner/Operator to obtain a formal approval by Aviation Authority having jurisdiction on the aircraft, for any adaptation necessary before incorporation of the present Service Bulletin.

3. ACCOMPLISHMENT INSTRUCTIONS

GENERAL NOTES

a) Place an identification tag on all components that are re-usable, including the attaching hardware that has been removed to gain access to the modification area and adequately protect them until their later reuse.

b) Shape the cables in order to prevent interference with the structure and the other existing installations, using where necessary suitable lacing cords and plastic cable tiedown.

c) Exercise extreme care during drilling operations to prevent instruments, cables and hoses damage.

d) After drilling, remove all swarf and sharp edges.

Apply on bare metal a light film of primer unless the hole is used for ground connection.

e) During the installation of bonding braids or components requiring grounding, clean the surface structure in order to obtain a good ground contact.

f) Let adhesive cure at room temperature for at least 24 hours unless otherwise specified.

g) Exposed thread surface and nut must be protected using a layer of tectyl according to MIL-C-16173 grade I.

h) All lengths are in mm.

PART I NOTE Following instructions are applicable only to AW119MKII helicopters not equipped with STC SR03280NY. For helicopters installing the STC contact the STC holder.

1. In accordance with AMP DM 19-A-00-20-00-00A-120A-A , prepare the helicopter on ground for a safe maintenance. Disconnect the battery, all electrical power sources and/or the external power supply.

S.B. N°119-130 ALERT DATE: October 5, 2023 Page 12 of 60 REVISION: /

2. In accordance with AMP DM 19-A-06-40-00-00A-018A-A and with reference to Figures 1 thru 3, remove all external panels, internal panels and internal liners as required to gain access to the area affected by the installation.

NOTE  The positions for the installation of the Battery Discharge Detector are reported in Figure 2 View B-B. The one on the left side (near STA 472.0) of the nose has to be considered as the preferred position. The alternative one (near STA 0.0 and BL

0.0) should be used when the preferred position is not available.

 If preferred battery discharge detector installation position (refer to Figure 2 View B-B) is available, perform retromod P/N 109G5320P18-201 and battery discharge installation as described at step 3.

 If preferred battery discharge detector installation position (refer to Figure 2 View B-B) is not available due to the presence of the chip burner power module, perform retromod P/N 109G5320P18-201 and battery discharge installation as described at step 4;

 If preferred battery discharge detector installation position (refer to Figure 2 View B-B) is not available due to the presence of items other than the chip burner power module, perform retromod P/N 109G5320P18-101 and battery discharge installation as described at step 5.

3. Battery discharge installation - Preferred positi o n available.

3.1 With reference to Figures 1 thru 3, perform battery discharge detector retromod P/N 109G5320P18-201 as described in the following procedure:

3.1.1 With reference to Figure 2 View B-B and Figure 3 Section B-B, temporarily locate the bracket P/N 109-0315-73-123 in its installation position, and countermark n°2 holes positions.

3.1.2 With reference to Figure 3 Section B-B, drill n°2 holes Ø 14.25 - 14.38.

3.1.3 With reference to Figure 3 Section B-B, install n°2 inserts P/N NAS1832-08-3 by means of adhesive EA 934NA AERO (C054).
