Analysis

The pilot-in-command, a certified mechanic, performed his own maintenance on the acft. This maintenance required the removal, reinstallation & rigging of the ailerons. As the plt was taking off on the 1st flt after maintenance, the acft entered a roll after lift-off & crashed. An investigation revealed the controls to the left aileron were connected in reverse.
