Summary
On January 29, 2018, a Wayne Miller SPORT COPTER II (N767LW) was involved in an incident near Van Nuys, CA. All 1 person aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot’s decision to takeoff in gusting wind conditions with insufficient rotor rpm.
According to the pilot in the experimental amateur-built gyroplane, during the takeoff roll on runway 34 in gusting wind conditions, the pilot did not allow the rotor revolutions per minute (RPM) to adequately increase. He advanced the throttle and the nose pitched up. The gyroplane exited the left side of the runway and the rotor blades struck the propeller.
The gyroplane sustained substantial damage to the vertical stabilizer.
The METAR at the airport reported that about the time of the accident, the wind was from 350° at 17kts gusting to 22kts.
Per the National Transportation Safety Board's Pilot Aircraft Accident Report, the pilot reported in the Safety Recommendation section that, this accident could have been prevented if he had confirmed the proper rotor RPM.
This incident is documented in NTSB report GAA18CA114. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N767LW.
