Amphibious Vehicle Safety Questioned after 17 Die in US.

On Thursday, a Duck Boat, capsized and sank on a lake in Branson Missouri. 17 are dead, and of the 12 people who survived, 7 are in serious or critical condition. Questions are being asked about the safety of these craft, and given Murphy’s Ambassatours operates several, its worth a look. There have been several incidents involving amphibious vehicles in the last 20 years – in 1999, another DUKW sunk in Arkansas, killing 13. Closer to Home, the Lady Duck Sunk in the Ottawa River, killing 4 in 2002.

The DUKWs involved in the Arkansas and Branson Incidents are actually a modern replica of a World War II design. Ottawa’s Lady Duck was a modified Ford Pickup. Halifax’s Harbour hoppers are military surplus Vietnam Era LARC’s, so there are significant differences in terms of the vehicles involved, however a review of the Investigation reports into these incidents reveals similarities.

A Transportation Safety Board report into the sinking of the Lady Duck revealed that the vehicle was registered as a motor vehicle only, and not as a small vessel, thus it fell into a regulatory vacuum, and was not in compliance with marine regulations. Additionally, Small vessel regulations were very different in 2002 then they are today. Harbour Hoppers are regulated as Both a Bus (by the province), and as a Vessel (by Transport Canada) and are registered as vessels.

The TSB Report into the 2002 sinking of the Lady Duck, echoed some of the recommendations from the NTSB’s report into the Arkansas sinking, and actually included a portion of the report as an appendix. Specifically both the TSB and the NTSB recommended requiring the vessels posses enough reserve buoyancy to stay upright and afloat when flooded, and to remove canopies, or use canopies that will not restrict horizontal or vertical escape by passengers. Additionally, both reports cited a lack of maintenance to the vehicles, specifically surrounding pumps  required to remove water from the vessel.

The main cause of death in both the Arkansas and Lady Duck incidents was people getting trapped by the canopy, and being unable to escape. Photos of the Stricken Duck boat from Branson seem to show that the passenger area was fully enclosed on top and on the sides. the Harbour Hoppers use a awning, which is open on the sides. as well as they are registered vessels they must meet construction and stability regulations.

Witness reports indicate that waves on the lake in Branson were hitting 6′ in height at the time of the incident, due to a fast approaching thunderstorm. Ultimately the report into this incident will likely sight Weather and the decision to sail, the enclosed canopy, and a failure of regulators to implement recommendations from the 1999 Arkansas incident as the causes.

Don’t Drink and Boat.

these videos have been around for a few years – they were produced for AV-OG-TIL, a Norwegian NGO working to reduce the harmful effects of alcohol. They aim to raise awareness of the dangers of Impaired boating.

AC624 – Normal vs Not Normal.

By now, we have all seen and heard the stories about the landing of AC624, A Toronto to Halifax flight with a A320 Aircraft. This route and aircraft land in Halifax dozens of times per week. Saturday night, this one came up short.

Runway 05/23 is the main runway at YHZ. runway 05 is a quick landing, as after you exit the runway, you end up at the terminal. this runway was extended in 2012, and may have reduced the impact of this crash.

The MK airlines crash, the Same ILS Antenna was taken out, however then it was on a berm. the space between the berm and the end of the runway was filled in as part of the Extension.
note the Alignment of Runway 05 and taxiway J in 2007:

And now, on the Current Chart.

(Below) the aircraft sits on the runway. the ILS Localizer lays broken on the left at the end of the runway.

Compare that with the normal Approach below. Note the plane is also an Air Canada A320. Also note that windsock above.

Here is the touchdown. Rear wheels are down, and the nose is coming down. Note the windsock. AC624 came to rest right where it should have touched down.

How Low was the plane? Here is the crater it left in the snow, and on the left the remains of the ILS Localizer. also note the snapped off lead light in the foreground. thats an 8 foot fence.

These are the leading lights in advance of the broken one. Note the height difference.  This flight was luckey. The aircraft clipped powerlines, but somehow managed to miss the wooden telephone poles. also the large dent in the snow probably cushioned the impact, as the recent snowfalls were still relatively fluffy compared to the earth mound.

Below an AC flight landing. this is landing on runway 23. Note the clearance over the localizer

Parts of the Landing Gear lie among parts of the localizer, and the right side of the runway.

Thanks to ADS-B, You can watch a replay of the flight Here
