hi...i sent u a mail in your mail box here...think u might not have seen it...well i wished if u could help me regarding this checklist..if u can send me this also..i'll be thankful [email protected]

1 disengages the lock...and 2 supplies the hyd to lower ramp..well u need to practically do it ur self for once and u'll understand how it goes..u can go counter clock wise but to open the ramp u'll have to go more clicks to reach 1..at no 6 and three the hyd supply is cut off..thus making it safe for any accidental movement.this N means neutral.

i think...atm motor is pneumatic driven and it drives generator.when you put load on gtc for atm and engine simultaneously it may stall or give underload problems.that is why it is advised to shut atm at 10% rpm... what do u say guys!

means.... lets suffer some more

well the RGB oil pressure is 150 - 250 psi

any body there

well the vibrations are fine... any other clue

please give an input....hurry..please

hey big guys give an input...need help

A FALSE low propeller oil warning light has caused many shutdowns in air. the culprit was oil level float indicator...Hydraulic used is 5606..and oil level float indicator part no is 519661... do u guys get the same problem with the floats or there is another oil level float being used..please tell any other reliable float(s) that don't make a false warning.

A number of RGB's have failed due to quite a handsome size of metal chunks detected by magnetic drain plugs..what could be the possible reasons for this cause... oil used is 23699 and is changed properly. Propeller dynamic balancing is also done properly. engine used is T-56-A-15 unable to find a good reason for these overhauled RGB's.:confused:

1.check gtc bleed drop time.if it less the 8.5 sec from 30 to 15 psi.theres prob of leakage in ducts.if its ok..no leak. 2. i suppose u had checked the serviceability of air bleed valve and starter control valve. 3. TIT is ok .so i think no need of checking T.D amplifier 4.do CIP blowing and 14th stage air filter cleaning. hope this would help

thx guys...i also found the scavenge pressure limits..the book says for power section its 40-50 psi RGB=70-75 psi but practically on gages it hardly exceeds 35 psi.. ....... and tusker thx for welcoming a new person.. more over if you were serious about burying your books.. doesn't it hurt you to throw such a precious knowledge. any way thx

hi every one...! i needed to know that what is the oil scavenge pressure of power section and reduction gear of T56 A-15 engine...because i couldn't find it any where..

cleaning of 14th stage bleed air filter and CIP blowing might help...if problem persists do a ground run in mechanical governing...adjust mech gov from FCU if problem shows in mech gov...
