EC135 Technical Question
 

Folks, I thought I knew the answer but now have doubts. The lack of an accessible FLM means I appeal to you.

When you use the overhead panel switch to test the Warning Lights, are you just testing the red light bulbs or do you continuity check the full circuitry for each light?

This is mainly aimed at the Low Fuel warning lights. Are you “proving” the system or checking the bulb? I always thought it was a bulb check

JTT,

WRT the Low Fuel Warning you are testing the circuit right back to the Low Fuel Sensor.

Just looked at the SDS (a bit vague) and shown clearly in WDM.

Any chance of a reference ��

Why?

You looking for a new job Jayteeto?

Funny you should say that, I am rapidly approaching 60 years of age. I could be a 737 copilot soon.........

Let’s see how desperate O’Leary really is

WDM 28-43-14-00 Fuel Quantity Indication - FUEL INDICATION

Ta very much!!

RyanAir are looking for 900 pilots.
The demand for more money by their pilots has fallen on deaf ears, so they are walking - in droves.

Shame, JT's a 135 pilot. :E

Embraer build a 135 ��

Dave, you forget, I have always kept that shiny aeroplanes licence with IR current as my 60 yrs + insurance policy

60? Time to retire. I'm sure your RAF pension's bigger than my Army one. Mind you, you'll have to cut back on your trips to Florida. :)

On a practical side I can confirm that the Warning Unit test does indeed test the low fuel sensors as half a year ago the LOW FUEL 2 wouldnt light up during this test. The mechanics found that the WU and light bulbs were all faultless, but indeed the low fuel sensor in the tank had failed.

I have a 135 question for those operating the type out there.

Do you have any specific requirements for keeping the fenestron blades clean and preventing salt build up in the marine environment? I seem to remember that the 120 had to be cleaned and then some kind of lubricant/wax applied but it's been a long time since I flew that model and it was brief.

Anyone out there help?

Thanks
ET

Same with the 135 ... ( waxing)

Thanks Skadi that's just the kind of information I'm looking for, can that be applied by a pilot or is that an engineering job only? Sorry to be pedantic but I've just had the question asked of me and I wasn't sure. I don't fly the type yet so not armed with all of the info. Also is the waxing referred to in any documentation anywhere?

Cheers

I don't known whether it could be done by the pilot or not. It is a standard procedure in our 100h inspections, done by the mechanics. But no rocketscience...

ET,

Get yourself a copy of the EC135 CECG (Corrosion and Erosion Control Guide).

Its pretty extensive!!

As for the TR blades wax is old school now - I think because the wax is NLA.

Currently Silicone Dielectric Paste SIL 4 is used.

All info is in the CECG.

Thanks RVDT that's even better. I'll go see where I can stir one up from.

Cheers
ET
