## Probable cause

IMPROPER ATC CLEARANCE BY GROUND PERSONNEL AND POOR DECISION BY THE PILOT TO TAXI BEHIND AN AIRPLANE HOLDING ON A RUNWAY.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Propeller blast or jet exhaust/suction, taxi - to takeoff
  - atc clearance - improper, atc personnel(lcl/gnd/clnc) (cause)
  - planning/decision - poor, pilot in command (cause)
- Dragged wing,rotor,pod,float or tail/skid, taxi - to takeoff

## Analysis

AN ACFT WAS HOLDING ON THE RWY AWAITING TAKEOFF CLEARANCE WHEN THE ACCIDENT ACFT WAS MOTIONED TO CROSS THE RWY BEHIND THE HOLDING ACFT.  THE PLT OF THE ACFT ON THE RWY APPLIED POWER TO TAKE OFF & THE PROP WASH ELEVATED THE LT WING OF THE ACCIDENT ACFT CAUSING THE RT WING TO CONTACT THE GROUND.
