GATINEAU, QC, March 27, 2014 /CNW/ - The Transportation Safety Board of Canada (TSB) today released its
investigation report (A11H0003) into the 4 September 2011 runway
excursion of United Express Flight 3363, operated by Trans States
Airlines, at the Ottawa/Macdonald-Cartier International Airport.
The Embraer 145 was on a flight from Chicago to Ottawa with 44
passengers and 3 crew members aboard and landed Runway 32 during heavy
rain. Shortly after touching down, the aircraft skidded off the left
side of the runway, approximately 7,500 feet from the threshold. During
the runway excursion, both of the main landing gear collapsed, damaging
the wing and causing a fuel leak. Everyone aboard evacuated the
aircraft safely and there was no fire.
The investigation found that the aircraft speed during the final
approach exceeded the company's stabilized approach criteria. Despite
this, the crew did not perform a go-around, as per procedure when
airspeed limits for the approach are exceeded. Just prior to landing,
the crew applied engine power, which caused the aircraft to touch down
3,000 feet further from the threshold. The aircraft then hydroplaned on
the wet runway due to the higher landing speed, a soft landing and the
use of the emergency/parking brake, which disabled the anti-skid system
and prolonged the skid. The aircraft then lost directional control
while hydroplaning and veered off the left side of the runway.
Following the occurrence, the Ottawa International Airport Authority
bought two rapid deployment emergency shelters to provide shelter from
the elements following an emergency evacuation. The airport also plans
to undertake a complete resurfacing of Runway 14/32, including grooving
the pavement and adding 300 meter runway end safety areas (RESAs),
similar as to what was done on Runway 07/25 in 2012-13. In addition,
Embraer made revisions to its E145 aircraft maintenance manual to
clarify and ensure consistency of the information on the brake system.
