NATOPS1

"Condition is only happening on a steep decent into a higher altitude airport."

Are the flaps being moved at higher airspeeds (IE: 220KIAS for 10%) or are they slowing to 180 and then moving the flaps to 50%? 

What model (A,B,E,F,H,R,T,Q...) is the aircraft and which VVI is installed?

Bonjour, ma panne est:

L'avion penché à gauche des moteurs sont un 19600LBS, Frein appliquer.

3 services Amortisseur effectuer sur vérin

Pression bloc de frein OK

Dissymétrie Carburant vérifiée avec manuel OK.

Avez-vous des solutions ou un retour d'expérience?

 

Hello, my breakdown is: The plane leaned to the left of the engines are a 19600LBS, Brake apply. 3 services Shock absorber on cylinder Brake block pressure OK

Dissymmetry Fuel checked with manual OK.

Do you have solutions or feedback?

Lockheed says 64 +/- 4 psi for the Fuel Level Control Valve pressure relief valve setting.

To those concerned with Lars' production list, please have patience.

My working day (much overtime at the pharmacy) leaves me just about one evening hour at the computer.

Weekends I'm OTK.

Agree with PJVR99 

Nothing you can do from the outside to fix this problem.

Yes, if you are looking.

The cabin altimeter on the copilots instrument panel and the Pressure controllers differential pressure gauge.  

I think the true answer you are looking for is: No, there is no warning system for a high cabin altitude. Nothing that is originally installed equipment but there have been a few after market systems used.

Has three speed switch been changed? The 95% arms the bleed air ( does the on speed light illuminate?) and the 110%switch shuts down the APU.

Set 900C, TD in Auto (position I'm guessing it already is) with engine anti-ice off, close the #3 Bleed Air Valve and actuate the wing/ Emp anti-ice system and see what happens.

Torque/TIT and FF should not change.

Make sure temps go up in each section of wing/emp

Being very late in this conversation, I don't know if this has any bearing any longer, but as son of Lars I inherited printings for another

forty or so copies of the very last issue (30th). They are now assembled and could be sent for the cost of post and package, just like my father did.

I too would appreciate a copy; my email address is [email protected]

Thank you for sharing these items with us!!

Is your Battery always connected? Even with External power connected/ON the aircraft?

And to clarify you can start and run the APU for 20 min or more and ONLY AFTER the GEN is turned ON the APU will continue to run for (another) 20 min and then stop OR stops sooner?

NATOPS1, aircraft is glass cockpit, so I believe indicated rpm to be same as AUTOTACH. It does match

generator frequency. Problem is what to do to get off that 95% GI rpm. Changing the engine only puts

the problem on the ready line for the next time

Ok got it. ANY pictures? (if allowed)

Guess you can swap out the FSR maybe it has an issue or increase the GI/FI RPM closer to the upper limit.

If you reset the gen will it go on line without speed increase?

if you speed up the engine and get the generator on line will it stay online when slowing back to 95%

The Generator is "offline" below 95% as a function of the frequency sensitive relay so if the rpm is right at the limit to energize it may not, but the FSR relays are known to hold energized once above 95% to a number below 95% SOME say as low as 88% but I have never verified that number as it is impossible to dial down the rpm to 88%

To me the video focuses on a location that is far aft of the actual leak site. If you observe closely fuel is passing by and getting picked up by the airstream at the forward edge of the fuel pump access hinge plate. The boostpump access and strainer are both in that area; any maintenance been done in that area (filter cleaned or changed, fuel boostpump replaced?)?

How far forward is the leak?

What was the fuel level of the tank during the video and other times that it has leaked? Does it always leak at all fuel levels?

What pumps were operating? What valves open? transferring fuel? Crossfeed or only main tank pump and n crossfeed?

Check your vent lines inside the tanks; a cracked vent pipe will let fuel into the system and can vent overboard.

Are these RPM numbers AUTOTAC RPM numbers or RPM Gage numbers?

Sorry for all the questions.

SO I fully understand:

How much fuel is in the number 2 tank?

Do you turn ON the fuel boost pump in the number 2 tank when operating the APU?

When you start the APU it will run normally with the bleedair valve CLOSED and generator OFF; WILL it run for more than 20 min in this configuration?

Will the APU run with the bleedair valve OPEN and gen OFF for more than 20 min?

When you turn ON the GEN how long before the APU stops?

Are you starting the APU with BATTERY power only or is External power unit connected?

OK so does the APU shut off each time you turn on the Generator with the Bleed air valve open or closed?

Yes! The APU run's without problems!

Ok good.

The APU stops when you turn on an air conditioner, yes? Watch the EGT and see what it is reading when it stops.

Can you start an engine with the APU or does it stop?

Flux all the time or maybe only with prop anti ice on?

With Bleed Air Valve CLOSED, it runs without problems!

Will the APU run without problems with the Bleed air valve open AND NO air conditioners or other bleed air load applied?

When it stops can you start it up immediately without any issues?

Help narrow the fault by running it for 20 min with the bleed air valve closed. Does it stop? 

Start in NULL; TD may be in full take (thinks TIT is too hi)

O got it guess I should read better... No idea, don't know, never knew or don't remember... I do seem to remember this was a question LONG LONG ago and it is not in our level of pubs.
