Accident Number: GAA17CA494
Date & Time: 08/17/2017, 1540 PDT
Registration: N8230S
Aircraft: AEROTECHNIK L 13 SEH VIVAT
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 1 None
Flight Conducted Under:  Part 91: General Aviation - Personal 

According to the powered-glider pilot, during takeoff he noticed a slower than usual acceleration, but continued the departure.

He reported that, "after lift-off the glider exhibited a poor climb rate although the engine was running smooth."

Moments later, the glider stopped climbing, then descended and struck the roof of a building located about 800ft southwest of the departure end of the runway. The glider came to rest upright, after colliding with another structure, and was consumed by a post-crash fire.

The pilot recalled that during the startup sequence, he was, "anxious to get back to my home base" and that he had not used the checklist.

The pilot reported that he had taken off with the propeller in the cruise setting and the wing spoilers deployed.

The pilot reported that there were no preaccident mechanical malfunctions or failures with the glider that would have precluded normal operation.

Okay, I give up. How does a glider catch on fire?

Easy-peasy;
The L13 Vivat is a motorglider - engine in front.
