Narrative:

The near collision occurred during a sbound takeoff from a non movement infield area with a taxiing airplane. The airplane was taxiing wbound and perpendicular to my takeoff path. A sbound clearance for takeoff was given by the tower, including lower than 500 ft when crossing runway 25L. The takeoff static condition was 100 pounds heavy. A rolling takeoff procedure was selected due to the static condition. A rolling takeoff is similar to an airplane takeoff because a ground roll is required prior to liftoff. During the takeoff roll the airplane was partially blocked from my view by ground equipment. Additionally, most of my attention was focused straight ahead. Once the taxiing airplane was clearly in view I was committed to take off. Once reaching liftoff speed, the best rate of climb was maintained directly into the wind. My aircraft passed over the airplane approximately 50-75 ft above it. Although the airplane was very near, no evasive action was necessary. I feel there were contributing factors. Both aircraft were handled by different controllers, ground and tower. Also, operating from a non movement -- had the takeoff been from a runway, I believe a hold short instruction would have been given. Also, ground equipment obstructing the view of the taxiing airplane. And certainly an insufficient level of awareness on my part.

Title: SMA ON INITIAL TKOF LGB NARROWLY MISSES TAXIING ACFT.

Narrative: THE NEAR COLLISION OCCURRED DURING A SBOUND TKOF FROM A NON MOVEMENT INFIELD AREA WITH A TAXIING AIRPLANE. THE AIRPLANE WAS TAXIING WBOUND AND PERPENDICULAR TO MY TKOF PATH. A SBOUND CLRNC FOR TKOF WAS GIVEN BY THE TWR, INCLUDING LOWER THAN 500 FT WHEN XING RWY 25L. THE TKOF STATIC CONDITION WAS 100 LBS HVY. A ROLLING TKOF PROC WAS SELECTED DUE TO THE STATIC CONDITION. A ROLLING TKOF IS SIMILAR TO AN AIRPLANE TKOF BECAUSE A GND ROLL IS REQUIRED PRIOR TO LIFTOFF. DURING THE TKOF ROLL THE AIRPLANE WAS PARTIALLY BLOCKED FROM MY VIEW BY GND EQUIP. ADDITIONALLY, MOST OF MY ATTN WAS FOCUSED STRAIGHT AHEAD. ONCE THE TAXIING AIRPLANE WAS CLRLY IN VIEW I WAS COMMITTED TO TAKE OFF. ONCE REACHING LIFTOFF SPD, THE BEST RATE OF CLB WAS MAINTAINED DIRECTLY INTO THE WIND. MY ACFT PASSED OVER THE AIRPLANE APPROX 50-75 FT ABOVE IT. ALTHOUGH THE AIRPLANE WAS VERY NEAR, NO EVASIVE ACTION WAS NECESSARY. I FEEL THERE WERE CONTRIBUTING FACTORS. BOTH ACFT WERE HANDLED BY DIFFERENT CTLRS, GND AND TWR. ALSO, OPERATING FROM A NON MOVEMENT -- HAD THE TKOF BEEN FROM A RWY, I BELIEVE A HOLD SHORT INSTRUCTION WOULD HAVE BEEN GIVEN. ALSO, GND EQUIP OBSTRUCTING THE VIEW OF THE TAXIING AIRPLANE. AND CERTAINLY AN INSUFFICIENT LEVEL OF AWARENESS ON MY PART.
