Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The acft impacted the ground in an inverted position in about a 30 degree nose down attitude. The acft was observed doing aerobatics with the last maneuver a spin. The acft spun to an out of sight position behind the trees and a crash was heard. The CFI on this flt had been known to perform aerobatics in this acft and to allow students to do them. The pilot receiving instruction on the day of the flt had been recommended for an instrument rating check ride. One pilot who had flown with this CFI said limited aerobatics had been performed with him but the CFI performed at a poor proficiency level during aerobatics. A noted aerobatic pilot who had flown this acft said it spun relatively flat. He stated that without training most professional aerobatic pilots were unable to recognize either the direction or proper procedure for recovery from an inverted flat spin.
