Circumstances:
The airplane was engaged in a local sightseeing flight over the region of Whangarei, carrying one pilot, two adults, a mother and her one year-old baby. After takeoff, while climbing to a height of 300 feet, the engine failed. The pilot made a turn to the left, reduced his altitude and decided to return to the airport. He elected several times to restart the engine but without success. Eventually, he was forced to ditch the aircraft that crashed into the Whangarei harbor. The pilot evacuated the cabin and was able to assist both adults and the baby but unfortunately, the woman was trapped and could not be saved. The aircraft was lost.
Probable cause:
It was determined that the accident was caused by an engine failure due to the following factors:
- The engine failure was caused by a fuel starvation,
- The fuel starvation was caused by the petrol in the tank in use being forced to the outward end of the tank, thus vacating the tank outlets,
- The movement of the petrol away from the tank outlets was caused by a state of unbalanced flight,
- The state of unbalanced flight was caused either by corrective control to overcome the left wing low tendency, or by uncoordinated control during take-off,
- Underlying the causation factors is the inherent risk created by the design of the petrol system when the aircraft was flown on one partially-filled tank.

Circumstances:
The single engine airplane departed Paris-Le Bourget Airport at 1415LT on a flight to Rotterdam with two passengers and two crew members on board. Thirty minutes into the flight, while cruising at an altitude of 300 metres, the aircraft rolled to the left, entered a dive and crashed in a swampy area located in Mont-l'Evêque, east of Senlis. All four occupants were killed. The crew was repatriating the aircraft to The Netherlands as his owner, Mr. M. A. G. van der Leeuw, died in another Waco crash near Rotterdam 3 December 1936.
Crew:
Joachim Tissot, pilot,
Albertus Sommer, pilot.
Passengers:
Adriamis Hoertens,
Jacob Maltha.
Probable cause:
The accident is attributable to an in-flight breakup of the left airframe following, it seems, a resource following either a spin or a spiral and nose-down descent. The pilot who, at a given moment was in the clouds, would thus have, for a cause that the commission could not specify, lost the control of the plane. The aircraft would then have entered a spin or a steep dive and the pilot would have pulled it up sharply in sight of the ground, coming out of the clouds. It should be noted that the maximum load of 1'540 kilos indicated on the certificate of airworthiness was largely reached and that the speed of the aircraft must, at the time it was righted, have been very close to the speed limit of 300 km/h and that it could not, under these conditions, resist the acceleration due to a brutal resource.

Circumstances:
On May 3, 1936, at approximately 0650LT, at Detroit, Michigan, a privately owned airplane was involved in an accident resultant death to one passenger, serious injury to another, and minor injury to the pilot. A third passenger was uninjured, and the aircraft was completely destroyed. The airplane, a Waco Model UIC, bore Federal licence number NC13420. The pilot was unlicensed. He had formerly held a Federal Transport pilot's licence, which expired on December 31, 1933. Returning from a cross-country flight to Louisville, Kentucky, the pilot landed at the Wayne County Airport to inquire about weather conditions at Detroit City Airport. He took off again a few minutes later to fly to the latter airport, which is but a short flight from the former. While circling the field at an altitude of about 200 feet preparatory to landing, the engine suddenly stopped. The pilot decided that he could not reach the airport and attempted to land downwind in some vacant lots. He overshot these badly and rather than risk striking houses, guided the nose of the airplane between two trees at the end of the vacant lots. The trees were struck while the airplane was still about 10 feet in the air, tearing off the wings and empennage. The engine and fuselage continued on about 25 feet before striking the ground, the slid along for about 20 feet more. The two passengers in the rear seat, who were under a single safety belt, were thrown forward from under the belt by the impact, causing fatal injury to one and serious injury to the other. Careful examination of the wreckage disclosed that the Lunkenheimer gasoline drain was in the drain position. This valve is located in such a manner that it is only about an inch from the left rudder pedal and a large movement of the rudder pedals, while taxying, could probably cause the valve to be accidentally opened. As the pilot states that he did not use this drain at any time during the trip, it is probable that while taxying at the Wayne County Airport, the valve was accidentally kicked open, allowing the gasoline to drain away, the supply being exhausted while preparing to land at the Detroit City Airport, thus causing the sudden engine stoppage. A check of the entire flight discloses that the pilot had put in approximately 8 hours of night flying just previous to the accident, and was probably greatly fatigued. This would had an effect on his judgment of speed and distance on the forced landing, in which he erred considerably.
Crew:
James H. Baughn, pilot.
Passengers:
Sadie Rowley, †
Joseph M. Charlton,
Morrell D. Banker.
Probable cause:
It is the opinion of the Bureau of Air Commerce that the probable cause of this accident was accidental opening of the gasoline drain valve while taxying, together with the pilot's misjudgment of speed and distance while negotiating a forced landing.

Circumstances:
An Armistice Day Air Pageant was held at Pontotoc Airfield, Pontotoc County, Mississippi, on November 10 & 11, 1935. Air pageant organizer and pilot Dean Faulkner offered 1$ rides in his bright-red four-seat Waco UIC cabin biplane. On November 10, at 1330LT, he took up three of his cousins (Henry Graham, Lamon ‘Red’ Graham and Bud Warren) to fly over the Graham family farm. The Graham farm was located at 940 Benjamin Road, Thaxton, Pontotoc County, about 10 miles northwest of Pontotoc Airfield, about 4 miles north of Thaxton. The aircraft crashed within the boundaries of the Graham farm, killing the four occupants instantly. Reportedly the flip-over controls were found on the side of Lamon ‘Red’ Graham, who was a student pilot.
