NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
Following an uneventful flight in the tailwheel-equipped airplane, the pilot entered the airport traffic pattern for the nontowered airport, which featured a single turf runway. The pilot announced his position on the airport’s common traffic advisory frequency (CTAF). The pilot continued to turn onto the base leg and then onto final, announced his position on each segment, and landed in a 3-point attitude. During the landing roll, the airplane struck a stationary, occupied lawnmower and a truck on the right side of the runway. The pilot further reported that he did not see the lawnmower while he was in the traffic pattern or during the landing sequence. The driver of the truck, who was talking to the person operating the lawnmower, reported that they were located on the right side of the runway, just beyond a turnoff to the taxiway, and were discussing an issue with the mower. The driver further reported that the lawnmower operator did have a headset connected to an aircraft transceiver; however, he was not wearing it during the conversation. It is likely that the nose-high attitude of the tailwheel-equipped airplane and the pilot’s position in the rear seat reduced the pilot’s forward visibility during the landing and subsequent landing roll precluded his ability to see objects directly in front of the airplane. However, the pilot would have had adequate visibility to inspect the runway for obstructions while operating in the traffic pattern. In addition, if the lawnmower operator had been using the transceiver to monitor the CTAF, it is likely that he would have heard the approaching airplane and repositioned the lawnmower off the runway before the airplane landed.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's failure to observe the runway environment while operating in the traffic pattern and his subsequent failure to maintain clearance from a lawnmower on the runway during the landing roll. Contributing to the accident was the lawnmower operator's decision to remain on the runway while troubleshooting the mowing equipment without monitoring the airport's common traffic advisory frequency.
On August 6, 2015, about 1030 Pacific daylight time, a tailwheel equipped Ryan Aeronautical ST3KR, N48701, was substantially damaged when it collided with an occupied riding lawn mower during landing at the Frazier Lake Airport (1C9), Hollister, California. The airplane was registered to, and operated by, the pilot under the provisions of Title 14 Code of Federal Regulations Part 91. The private pilot sustained minor injuries and the pilot rated passenger sustained serious injuries. The pilot rated occupant of the lawn mower sustained fatal injuries. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight. The local flight originated from the Reid-Hillview Airport, San Jose, California, at 1000, with 1C9 as the intended destination.
In a written statement to, and a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge, the pilot reported that he initially transmitted his intention of landing about 8 miles from the airport on the airport's common traffic advisory frequency (CTAF). The pilot said he then entered the airport traffic pattern on a right downwind for runway 23, reported that he was on right downwind and continued to announce his position on downwind, base, and final for the runway on the CTAF. The pilot stated that he landed slightly longer than normal, and during the landing roll, the airplane struck a lawn mower. The pilot further reported that he did not see the lawnmower while he was in the traffic pattern or during the landing sequence.
Examination of the airplane by a Federal Aviation Administration (FAA) aviation safety inspector revealed that the fuselage of the airplane was structurally damaged. The lawnmower, yellow in color, remained partially underneath the engine of the airplane, with the front of the lawnmower facing in the direction of travel of the airplane. In addition, the inspector reported that the airplane also struck a parked vehicle, which was white in color that was parked adjacent to the lawnmower.
A witness, who was located in the run up area for runway 23, reported that he saw the lawnmower on the right side of the runway. The witness said that during his taxi to the run up area, and during his run up, he never heard any radio communication from the person on the lawnmower, however, he did hear the pilot of the accident airplane report that they were 5 miles out, followed by a report on downwind. The witness further reported that he saw the accident airplane on final approach, just crossing the runway numbers about 50 to 70 feet above ground level, and that it seemed to be fast, as if he was conducting a long landing. He then observed the airplane land in a 3-point attitude, and shortly after, impact the lawn mower.
The driver of the truck who was located adjacent to the lawnmower, reported that he was having a conversation with the person who was seated on a mower about an issue he was having with it not cutting properly. He stated that they were just past the turn off to the taxiway on the right side of runway 23, and at no time heard or saw the airplane prior to the collision. He further stated that the person on the lawnmower did have a headset connected to an aircraft transceiver; however, he did not have the headset on during their conversation.
1C9 is a non-towered airport, which features a single turf runway (5/23) that is 2,500 feet in length and 100-feet wide. In addition, the airport features a water runway located adjacent to the turf runway that is 3,000 feet in length and 60-feet wide. Review of the FAA Airport Facilities Directory revealed that at the time of the accident, no remarks were present for mowing operations. In addition, at the time of the accident, no Notices to Airmen (NOTAMS) were present for mowing operations.
The Ryan Aeronautical ST3KR is a two-place, tandem configured, low wing, tailwheel equipped monoplane, manufactured in 1942. The airplane is commonly flown from the aft seat, which is located just aft of the wing. Visibility from the aft seat is limited in a three-point attitude due to the nose high angle and engine.

Sheriff's authorities suspect an airplane landed at Frazier Lake Airpark and then struck a riding mower Thursday morning, killing the Hollister man on the grass runway, according to a statement released Thursday evening.
The sheriff's office, which acts as the coroner, released the victim's identity Friday morning.
The victim was Douglas Ralph Jackson, 75, of Hollister.
The San Benito County Sheriff's Office is investigating the 10:30 a.m. Thursday crash at Frazier Lake Airpark resulting in the death of a 75-year-old Hollister man on a riding mower.
Investigators believe the single-engine plane on the way from San Jose to the private landing strip in San Benito County touched down on the grass runway and then struck the riding mower, according to a statement.
The pilot of the airplane is from Monte Sereno and sustained minor injuries.
The one passenger was airlifted to a Bay Area trauma center with a large head laceration and his status is unknown, according to authorities.
Federal authorities will determine a cause. San Benito County sheriff's officials plan to release the fatality victim's identity after adequately notifying family.
According to that statement:
Our preliminary investigation shows the decedent was on a riding mower, on the runway. Frazier Lake Airpark is a private airfield with one grass and one water runway. The decedent was mowing the runway when an older WW2 style “taildragger” plane landed on the runway. The pilot did not see the male on the riding mower and struck him after landing. The FAA and NTSB are investigating as to the cause of the crash. As of this point neither weather nor mechanics seem to be a factor. The plane had completed its landing and struck the male after all wheels had touched down.
The pilot, from Monte Sereno, was en route from Reid-Hillview Airport in San Jose, to Frazier Lake where he has a hangar. He sustained minor injuries to his head and arm and was treated and released at the scene. He was cooperating with FAA and NTSB Officials. His passenger sustained a large head laceration and was airlifted to an area trauma center. His condition is unknown.
The FAA and NTSB will determine the cause of the crash. As of this point, there are no criminal charges pending. The identity of the decedent will be released shortly after next of kin have been notified.
