ATA Chapter: 26 Fire Extinguisher System
Issue: Inadvertent discharge of the fire extinguisher bottle.
Status: Incidents can be classified in two categories:
1. Inadvertent discharge during pre flight procedure- Caused by overlapping of test switch positions when test switch is moved rapidly from the Off to the EXT/WARN position
- Procedure in the flight manual will be changed:First from OFF to EXT (Cautions EXT & FIRE EXT must come on) and only thereafter to EXT WARN (Cautions EXT/WARN, FIRE EXT & FIRE E TEST must come on)
2. Inadvertent discharge due to defective fire detectors- First batch of defective sensors have been sent to the manufacturer in CW 22 for investigation.
- Failures were caused by ingress of moisture due to defective sealant

-
28
ATA Chapter: 31 Main Switch Panel (20VE)
New System: Audio Warning Single ENG Take-Off If only one engine main switch is in the FLIGHT position when the collective
is unlatched, a red warning CHECK ENG indication will appear and a special audio gong will be generated. The red flashing warning will last for five seconds (flashing at four times per
second) along with the special audio gong (which will sounds like: #go-go-go-go#). It will not be possible to acknowledge the special audio gong during these five seconds.
After five seconds a permanent red warning will appear, along with the standard audio gong. This standard audio gong can be acknowledged. The red warning will only disappear if/when both engine main switches are
put in FLIGHT position or when both are not in the FLIGHT position.
SB will be distributed in 2010

EC135 MGB Input Stage: Status of New Topography
New tooth topography was designed (different topography on LH and RH). Overload test (140%) and qualification test (endurance test) successfully
concluded in October 2009. Certification of new input pinions granted on December 17th 2009. Main XMSN with improved input pinions will have a new part number. First serial production main XMSNs with improved pinions will be on
production line by March 2010. Main XMSNs undergoing repair/overhaul will be getting new input pinions as
from March 2010. Every main XMSN which needs to be opened for any repair/overhaul will
generally receive new input pinions. Main XMSNs with improved input pinions are not affected by ASB 63-012 (oil
sampling every 100 hours).
-

EC135 MGB FS108 Spacer Tube
Wear on top surface of
spacer tube
Severe wear of tangs
Issue: The EC135 main transmission
spacer tube shows extensive wear and broken tangs. Additionally, the spacer tube wears more than expected on the top surface directly in contact with the upper mast bearing inner ring.
Root causes: The settling effect of the mast
assembly and the wear ofthe spacer tube result in aloss of the mast nut torque.
-
51
EC135 MGB FS108 Spacer Tube
Historical improvements introduced: Increase from 2 to 6 keys. Material of spacer from steel to titanium. Increase of nut torque from 350 Nm to 800 Nm. 1,600 hour interim inspection.
Further steps:
Short-term solution: A reference fleet is getting re-torqued at 50FH then every 100FH. The Ti-, Fe- and Ag-content in oil of further A/C of the reference fleet will be monitored if the
content of these materials will increase in the same proportion, mast nut will be re-torqued. Introduction of mast nut retorque into MSM at 150 hours TSN, TSO or since mast installation (at
400 hours if retorque at 150 hours shows no movement of nut). First main XMSN oil change will be shifted from 50 hours TSN, TSO to 150 hours TSN, TSO.
Mid-term solution: Design improvement of main rotor mast nut and spacer tube. Change request launched approved. First design proposal currently under detailed study.

ATA Chapter: 65 EC135 TRDS Bearings Failure
Issue: Since 2007 several tail rotor drive shaft bearings have seized, leading to rubber sleeve damage. The following failure modes have been observed:
Heavy corrosion: long immobilization time in humid/salty environment Incorrectly manufactured bearing seal retaining groove: loss of grease Slight corrosion, loss of inner play: high rotating speed increased operating temperature
Status: Design analysis has been launched with the purpose of investigating measures which could decrease
bearing temperature. The following results have been gathered: High rotational speed leads to high bearing operating temperature Rubber sleeve has an isolating effect on the heat flow of the bearing increase in operating temperature
Further steps for problem solution: The influence of the following parameters on bearing
temperature will be analyzed in detail: Bearing grease amount Bearing grease type Isolating effect of sealing Isolating effect of rubber sleeve
Test results planned end of October 2009
