    BIRD FOD

    Dear during landing portion PL remain much vigilent for these flying FOD.... but once PL reaches his final aproach and landing speed after this it is much difficult for PL to avoid these... So in my opinion it is the duty of mobil as well as ATC to clear enviroment from birds near the landing points.... 

    Thanks

    I disagreed with this.....  Explain how the ignitor plugs are the defaulters in this case??? REGARDS... 

    Dear Moeed as you know that one of ignition plugs became defective what happen in flight one plug unable to ignite the rich mixture but on ground you can not judge.The pattern of mixture is changed as enrichment switch is  selected to normal.

    Hello world Flyer expertise ,how PL can avoid bird FOD while landing and takeoff. My opinion is, the  vision of PL is   like eagle vision ,bird FOD can be avoided during LDG and T/off

    Not much to be done there. Airfield safety should be taking care of birds thru keeping grass verges short, falcons, etc. Nothing a crew can do

    once they're committed to land or take off

     

    Thanks petter

    ATM GENERATOR won’t run ESS Bus

    Struggling with an ongoing ATM gen problem. Getting good freqs good volts. Turn ATM gen to on gen out light does not come on but the ESS bus off lite stays on and all systems requiring 3 phase power do not work. 

     

    The single phase AC items on bus do work. AC instrument fuel control bus works and Elevator trim works. 

    We have changed contactor, generator, GCP, and voltage regulator multiple times with no luck. Anyone seen this??

     

    Thanks

     

    Have check battery was connected and  SW solenoide CB push in? EXT power contactar is not de-energized , check the K9 contactor

    Thanks

    Are you performing vibration analysis, prop balancing, torquemeter runout, 135 day signature checks with Honeywell VXP equipment? vibration maybe the key.

    Icing Conditions

    Thanks a lot for your answer "Hehe".

    My concern is with potential significant ice accumulation under severe icing conditions and potential flow "disruptions" in front of lower pitots tubes (static pressure error ?)  with AoA for exemple.

    What beautiful picture of B model aircraft

    ENGINE FLAME OUT

    Thank you. based on this and your previous mentioning the shift

    to another engine, it sounds like you have a rollback, a problem

    with the synchrophaser. Check out synchrophaser, sych rack, and

    also run synch box tester. sometimes the problem can be a false

    signal generated by a seemingly good valve housing. also check

    all 4 prop pulse generators.

    Thanks

    Regards Munir Abbasi

    is this in level flight, during a ground run, taxi, descent, take off? what are throttle sttings?

    Throttles are in takeoff range on the ground, aircraft lineup in the runway for departure

    Five total? Same aircraft? Same engine? or just five across your fleet?

    mounting bolts or bolts on generator?

     

     Same aircraft but different engines.GEN stator mounting screws were broken and cooling Shroud also broken due to RGBs were defective these occurrences of vibration could not observe by flight crews, only  GEN OUT light came on with V/F/L zero.
