Staudacher S-300, N126RG: Accident occurred June 02, 2016 in Prospect Heights, Cook County, Illinois

NTSB Identification: GAA16CA280
14 CFR Part 91: General Aviation
Accident occurred Thursday, June 02, 2016 in Prospect Heights, IL
Probable Cause Approval Date: 08/03/2016
Aircraft: STAUDACHER AIRCRAFT INC S 300, registration: N126RG
Injuries: 1 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot of the tailwheel-equipped airplane reported that he landed hard and bounced. The pilot further reported that after the bounce, he knew that the left main landing gear had collapsed, and he held the left wing off of the runway until the airplane slowed and the wing stopped producing lift. Subsequently, the airplane veered off the runway to the left and collided with runway signs, which resulted in substantial damage to the horizontal stabilizer. 

The pilot reported that the "½ inch fine thread bolt" on the left main landing gear failed during the bounced landing.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's incorrect pitch control during the landing, which resulted in a hard bounced landing, and subsequent left main landing gear collapse, a runway excursion, and a collision with a runway sign.
