Levelling and Weighing

Text Box: 5-12 AIRCRAFT GENERAL

LEVELING (C90A/B/GT)

 

  • The aircraft may be leveled by inflating or deflating the main or nose gear struts. 
  • To level the aircraft laterally, use a bubble level across the two inboard seat  tracks and deflate the tire or strut on the high side of the aircraft until the bubble centers. 
  • To level the aircraft longitudinally, attach a cord and plumb bob to the upper Phillips-head screw, located at W.L. 122.0, just forward of the cabin door. 
  • Inflate or deflate the nose gear shock strut as required to pass the cord over the center line of a second Phillips-head screw directly below at W.L 91. at the bottom of the door.
  •  Suspending the plumb bob in a container filled with light engine oil dampens its movement.

LEVELING (C90GTI)


  • Perform the JACKING procedure.
  • Place the spirit levels at the forward end of the seat tracks. 
  • Then place a spirit level on the RH outboard seat track. 
  • Adjust the nose jack until the aircraft is level in pitch.
  • Then place a spirit level across the inboard seat tracks and adjust the rear spar jacks until the air- craft is level in roll. Verify the aircraft is level in pitch and roll before performing the required maintenance procedure(s).  
  • Once complete remove the aircraft from the jacks.

TTP B1-L3 ATA 56 Beech 90 Series B2-L1 Windows The King Air for w ard windshields are fo r med from t w o-p l y glass in an int e g ral aluminum frame. The t w o glass plies are bonded t o gether with a center po l yvi n yl sheet that co n tains the fine wire heating g rids. The windshields are electrostatical l y  coated and cu r rent-production windshields are sur f ace sealed. All the side wind o ws are const r ucted from ac r ylic plastic. WINDSHIELDS   The electrical l y heated laminated glass windshield is subject to the g radual process of delamination due to the effect of chemical action and differentials of temperature and pressure incu r red during pressurized flights at v a r ying altitudes and under v a r ying w eather conditions. This delamination is not detrimental to the st r uctural int e g rity of the windshiel d , b ut ...
