Subject: Overdue Aircraft Located Crashed Near Williams HA Clark Field 

WILLIAMS, Arizona – On Sunday, April 18th around 6:00 PM, deputies from the Coconino County Sheriff’s Williams Sub-Station received a report of an overdue aircraft from Vista, California. A family member of one of the overdue occupants indicated that the missing parties had not reported for work as scheduled on Sunday. The occupants have been identified as Timothy Michael Gill, 37, and Joylani Roseann Kamalu, 38, of Vista, California.

The reported destination for the aircraft was the Grand Canyon Airport for a scheduled appointment in the Tusayan area at 9:00 AM, having departed from the Sedona Airport. Investigators immediately focused on attempting to search for the aircraft at the Sedona and Grand Canyon airports.

Due to the potential of the aircraft being in multiple jurisdictions, the State Search and Rescue Coordinator was notified, who in turn requested assistance from the US Air Force Civil Air Patrol to determine the last known direction and location of the aircraft. This information from the US Air Force directed search efforts to an area northeast of the Williams airport, also known as HA Clark Airfield.

Deputies requested the assistance of the Arizona Department of Public Safety Air Rescue helicopter out of Kingman. 

On Monday, April 19th at 1:40 AM, DPS Air Rescue located the aircraft crashed in a wooded area in near the Williams Airport. Two occupants were confirmed deceased in the downed aircraft.

The incident is currently under investigation by the NTSB, FAA, the Coconino County Sheriff’s Office, and the Coconino County Medical Examiner’s Office. No further information is available at this time.

  1. There was probably video footage of the trip since they were avid youtube posters, sad deal on apparent first trip with there new to them C140.

    1. Yeah, according to another Youtuber the Cessna 140 had just been purchased by them. Sad, they seem like such great people. I wonder what the cause is going to be. The area they were flying in has some really high elevations, I wonder if that was a factor.

    2. I am guessing they fueled up in Williams before they reached the destination Grand Canyon airport that morning and the little 140 just couldn't perform with the weight and field elevation on takeoff with that 90 hp Cont. :/

    3. Hate to think that the crash might be related to a fuel stop in Williams to get lower cost 100LL vs taking on fuel at Sedona or GC.

  2. 02:30Z is 7:30 PM at Williams, sunset was 7 PM there on 16 April.
    Temp was 42F, not windy per METARS (From

  3. Engine examination will be of interest. Airplane may not have flown for a year or more after previous owner's 3rd class medical expired at the end of 2019 (Med date = October 2017, was good for 24 months due to being over age 40).

    Continental documented the possibility of lifter corrosion from "hangar runs" of the engine that don't dry out moisture. Guidance to manage the concern in linked document:

  4. During the 7,000 or so hours that I flew professionally, in everything from gliders and jump planes, to Pt. 135 cargo and 135 airline, never once did it occur to me to record my activities so as to share them with the world. The potential dangers associated with flying are great enough as it is without adding the distractions associated with recording oneself and chatting with potential viewers.
    I can't help but wonder that if the pilot had been devoting his concentrating solely to flying his airplane he might have noticed how its performance was degrading in the thinning air and mentally prepared himself better for the possible eventualities.
    In 'Fate is the Hunter' Earnest Gann wrote some words on this topic.....

    1. So you know that the person flying the airplane was distracted and that's why the plane crashed? What other forms of magic do you believe in besides clairvoyance?

    2. That is a very resonable assumption. I see they would often use the hashtag #grassrootsaviation. I don't know what "grass roots" aviation is, but it sounds like something that would have a high accident rate. Greater than that of GA and certified aircraft.

    3. Tim and Joylani were friends of mine and they loved flying. They also loved sharing their adventures with the world. If you had the chance to see any of their youtube videos, you would notice that they saved their "chatting with potential viewers" to when they were back on the ground. They would have some chatting during flight occassionally on video, but nothing more than most pilots would probably have with their passengers in a small plane.

  5. Only critique I'll offer is that this accident occurred either in fading light or true nightfall. Where these events unfolded two hours earlier they would've had a much easier time dealing with whatever problem they encountered. Where they needed to set the plane down then there's an excellent chance they could've done so with some damage to the airplane but otherwise walk away safely.

    Setting a plane down when it's dark outside is pretty scary business.

    Really wish they'd planned this flight to occur in full daylight, is the one thing I would change.

    1. Perhaps there was unplanned delay in making the departure from Sedona.

      For reference, the supposed 7:30 pm crash time on 16 April was halfway between sunset and 8 pm nautical twilight, when it becomes too difficult to perceive the horizon.

  6. Not much ground disturbance around the aircraft. It possibly went straight down. Heavy, hot, bank, stall, crash.
