Incident History
Private Australian
On 26 January 2017, the pilot of a Grumman American Aviation Corp G-73 amphibian aircraft, registered VH-CQA (CQA), was participating in an air display as part of the City of Perth Australia Day Skyworks event. On board were the pilot and a passenger. The pilot of CQA was flying ‘in company’ with a Cessna Caravan amphibian and was conducting operations over Perth Water on the Swan River, that included low-level passes of the Langley Park foreshore. After conducting two passes in company, both aircraft departed the display area. The pilot of CQA subsequently requested and received approval to conduct a third pass, and returned to the display area without the Cessna Caravan. During positioning for the third pass, the aircraft departed controlled flight and collided with the water. The pilot and passenger were fatally injured.
Chalk's Ocean Airways
On December 19, 2005, about 1439 eastern standard time, a Grumman Turbo Mallard (G-73T) amphibious airplane, N2969, operated by Flying Boat, Inc., doing business as Chalk’s Ocean Airways flight 101, crashed into a shipping channel adjacent to the Port of Miami, Florida, shortly after takeoff from the Miami Seaplane Base. Flight 101 was a regularly scheduled passenger flight to Bimini, Bahamas, with 2 flight crewmembers and 18 passengers on board. The airplane’s right wing separated during flight. All 20 people aboard the airplane were killed, and the airplane was destroyed by impact forces. Flight 101 was operating under the provisions of 14 Code of Federal Regulations Part 121 on a visual flight rules flight plan. Visual meteorological conditions prevailed at the time of the accident.
Chalk's Ocean Airways
The flightcrew had completed a 14 cfr part 135 charter flight and had landed in the harbor at Key West, Florida. They had moored the seaplane and departed. About an hour later, they reboarded the seaplane to fly it to an airport for refueling, then to return to the harbor to board the passengers. During takeoff, the seaplane was observed to pitch nose up, roll left, and crash nose down in the harbor. Due to the damage done by tidal flow and recovery attempts, the exact condition of the aft bilge drain plugs was unknown. During a check of the CVR recording, the crew was not heard to call out the bilge pumps during the before-takeoff checklist. After lift-off, both pilots made comments about keeping the nose down due to water in the aft portion of the aircraft. Both pilots were killed.
Virgin Island Seaplane Shuttle
The pilots lost aileron control shortly after takeoff while in a left turn. The left turning tendencies of the aircraft could not be corrected and the aircraft crash landed in the Caribbean Sea. Post crash inspection of the aircraft revealed the left aileron control cable was trapped within a bundle of electrical wires and cables. This occurred when an electrical cable from a reverse current relay in the right wing to the main junction box in the left cabin area at the center wing was changed and secured. The aileron cable chafed through the protective cover of the large electrical cable. When contact was made with the metal electrical cable the aileron cable arched at several points and separated at two different points causing a loss of aileron control. A passenger was killed while 14 other occupants were rescued.
Trans Catalina Airlines
While taking off from the Avalon harbour, the seaplane struck three successive waves. On impact, the left engine and the left were torn off. The aircraft came to rest and was damaged beyond repair. All 11 occupants escaped with minor injuries.

The aircraft departed Anchorage on a seabird survey flight to Kodiak. While cruising over the north Pacific Ocean, the airplane crashed into the sea and was lost without trace. The pilot was unable to send any distress call. SAR operations were conducted but eventually suspended after few days as no trace of the aircraft nor the four occupants was found.
North Coast Air Services
About two minutes after it took off from Prince Rupert seaplane base, the pilot initiated a turn when the airplane lost height and crashed onto a mountain slope located about 3 km southeast of Prince Rupert. The wreckage was found a day later and while seven occupants were rescued, three others, among them the pilot, were killed.
Catalina-Vegas Airlines
While leaving the Avalon-Pebbly Beach seaplane base, the airplane struck waves caused by an engine-boat. The airplane went out of control, overturned and crashed. A pilot was killed while three other occupants were injured. The aircraft was lost.
Gold Bond Stamps Company
Shortly after a night takeoff from Huron-William Washington Howes Airport, while in initial climb, the seaplane stalled and crashed. Both occupants were seriously injured and the aircraft was damaged beyond repair. At the time of the accident, the OAT was 18° F (-8° C) with a relative high humidity.
Nitto Airlines
Shortly after takeoff from Osaka-Itami Airport, the crew encountered engine problems. The seaplane stalled and crashed in a rice paddy field. Two occupants were killed while eight others were injured.
Pacific Western Airlines - PWA
Few minutes after its takeoff from Kemano, while cruising at an altitude of 5,000 feet, the seaplane hit the slope of a mountain. The wreckage was found few hours later and all five occupants were killed.
United Producing Company
This flight was for the purpose of transporting 10 men from a private duck hunting camp at Lower Mud Lake, Louisiana, near the mouth of the Mermentau River, to Shreveport, Louisiana, about 190 miles north-northwest. There were ten in the hunting party; the other four and baggage for all 14 were flown to Shreveport in another company airplane from the Lake Charles, Louisiana Airport some 30 miles from Lower Mud Lake. At the time of takeoff, weather over the route was overcast with the base of clouds at 800 or 900 feet, and tops sloping from about 2,500 feet at Lower Mud Lake to 7,000 feet at Shreveport. The 1628 weather at Lake Charles Airport, 160 miles from Shreveport, and on course, was: measured ceiling 900 feet, overcast; visibility 10 miles; temperature 47 degrees; dew point 44; wind northeast 17; altimeter 29.92. The gross weight at takeoff was approximately the prescribed maximum of 12,750 pounds; the C. G. was located within prescribed limits. The pilot was W. C. Huddleston, the copilot L. R. Schexnaydre. Takeoff was made at about 1635 from Lower Mud Lake. The aircraft first reported at 1704 to the CAA Alexandria radio station, giving its position as on top (of clouds) over DeRidder, Louisiana, approximately 76 miles from the point of departure and on course. At this time the pilot requested and received Shreveport weather: measured ceiling 600 feet, variable, overcast; visibility 2 miles: drizzle, fog; temperature 36; dew point 34; wind west-northwest 17; altimeter 30.02; ceiling variable 400 to 800 feet. Alexandria radio also advised that it was very possible the drizzle would turn into freezing drizzle because of low temperature in the Shreveport area. The pilot acknowledged and said that he was going to fly on top to Elmgrove, a fan marker about 16 miles southeast of Shreveport, then file an instrument let-down to Shreveport. He then reported that he was in the clear and cloud tops were at 4,500 to 5,000 feet. At 1719 the flight reported to Shreveport Approach Control as being 30 miles southwest of Natchitoches, Louisiana, about 70 miles from Shreveport, altitude 5,500 feet, 500 on top, inbound to Shreveport, and asked for an Instrument Flight Rules clearance for approach. The flight was then issued a 500-feet-on-top clearance to Shreveport Instrument Landing System outer marker, and the pilot replied that he was estimating the outer marker at 1750. At approximately 1729 Approach Control again checked with Fort Worth Air Route Traffic Control to ascertain if any traffic in the vicinity would prevent descent from 500 feet on top to 2,000 feet, with a new clearance to Forbing, Louisiana, a range intersection about 10 miles southwest of the Shreveport Airport. ARTC advised that if the aircraft was above 5,000 feet to start it down immediately. Approach Control then asked the pilot has altitude; he replied that he was now at 6,000 feet, more than 500 feet on top. Approach Control then cleared him to descend to 2,000 feet, maintaining 2,000 feet to Forbing, with no delay expected, to report leaving the 6,000-foot altitude and when passing 5,000 feet, and to start descent immediately. The flight was then advised of reported icing at 4,000 feet and above and given the 1704 Shreveport weather: 300 feet scattered, measured 600 variable, overcast, 2 miles visibility, light snow and fog. This was acknowledged. The flight left 6,000 feet at 1730 and 5,000 feet at 1732 reporting temperatures of 40 degrees F. and 32 degrees F., respectively. At 1745 the flight advised that it was at 2,000 feet and had picked up a "load" of ice. It was cleared to 1,500 feet, the minimum safe altitude, at which time the pilot said he was on the back course of the localiser. The flight was then requested to report when passing the localiser upon winch Approach Control would bring it in. The pilot requested the ground temperature, which was given as 34 degrees F. The next contact advised being at 1,200 feet which was all he "could hold." At 1747 the flight was cleared for an approach and was asked for an arrival estimate at the outer marker. At 1749, the last radio contact with the flight, it reported being contact below the clouds with Wallace Lake in sight and "going in." No emergency, as such, was declared. Several persons near the crash site heard the engines and then saw the aircraft just below the overcast some 400 to 500 feet above the ground. It descended steeply, banking sharply from side to side several times with very loud but normal engine noise. It passed from view beyond trees; almost immediately a crash was heard and a glare seen.
