On June 21, 1990, a Grumman G-164A (registration N29SK) operated by Faunce, Daniel H. was involved in an aviation accident near Tekoa, WA. Investigators recorded the probable cause as: FAILURE OF THE PILOT TO MAINTAIN CLEARANCE BETWEEN THE AIRPLANE AND TALL GRASS ADJACENT TO THE GRAVEL STRIP. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An agricultural aircraft veered off a dirt strip after its spray boom caught in tall grass during a crosswind landing, causing a spin and post-impact fire. The pilot reported no mechanical issues.
Accident Details
During the final approach to a private dirt runway following an aerial application mission, the pilot encountered a crosswind and lowered the right wing to counteract the drift. As the aircraft touched down, the low-hanging right-wing spray boom struck tall vegetation bordering the runway. This caused the airplane to pivot abruptly and subsequently collide with terrain in a nose-down attitude.
Post-Impact Fire
The force of the impact ruptured the fuel tanks, and the released fuel ignited. The resulting fire consumed the aircraft. The pilot, who survived the accident, later stated that there were no mechanical failures or malfunctions with the airplane prior to the event.
Context
The accident occurred during daylight hours at a private airstrip. The pilot was conducting an aerial application flight, a common operation involving low-level maneuvering and often requiring precision landing on unprepared surfaces.
