SWANSON TIGER MOTH 80S/N: TM44

Summary

On May 17, 2013, a Swanson TIGER MOTH 80 (N928VS) was involved in an accident near Lynden, WA. The accident resulted in 1 minor injury. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this accident to be: The pilot's failure to maintain clearance from trees during final approach and his obscured vision due to the sun glare.

The pilot reported that following an uneventful flight, he noted that the wind favored landing to the west, into the sun. During final approach to the runway, the pilot's view of the runway was obscured by the sun glare, however, he "thought I would get through the blind spot" and elected not to abort the landing. Subsequently, the right wing of the airplane struck a tree and the airplane impacted the ground, which resulted in structural damage to both the upper and lower left and right wings, and forward portion of the fuselage. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. Official sunset was about 17 minutes after the time of the accident.

This accident is documented in NTSB report WPR13CA235. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N928VS.
