Incident Summary
A pilot was preparing to pick up a banner using a grappling hook. The hook was deployed without visually confirming that the cable was properly deployed. Instead, the cable became wrapped around the aircraft's stabilizer.
Sequence of Events
The pilot then returned to the airport to drop the banner. When the banner was released, the cable that had been wrapped around the stabilizer traveled forward and jammed the elevator. This resulted in an in-flight loss of control. The aircraft subsequently collided with terrain.
Pilot Action
According to the investigation, the pilot did not ensure that the grappling hook cable was properly deployed by visually checking the cable. This oversight allowed the cable to wrap around the stabilizer, setting the stage for the elevator jam during banner release.
Outcome
The in-flight loss of control led to a collision with terrain. No further details about injuries or damage were provided.
