DARTMOUTH, NS, Feb. 18, 2014 /CNW/ - The Transportation Safety Board of
Canada (TSB) today released its investigation report (A12A0082) into
the August 2012 runway overrun of a Volga-Dnepr Airlines aircraft in
St. John's, Newfoundland and Labrador. Landing accidents and runway
overruns have been identified as an issue on the TSB Watchlist.
On 13 August 2012, an Ilyushin IL-76TD-90VD, a four-engine heavy-cargo
transport aircraft, departed Prestwick, Scotland, for St. John's
International Airport, Newfoundland and Labrador, with 10 crew members
on board. Following touchdown on Runway 11, the crew was unable to stop
the aircraft prior to the end of the runway. The aircraft came to rest
in the grass, with the nose wheel approximately 640 feet beyond the end
of the runway surface. There were no injuries, and aircraft damage was
limited to cuts and localized rubber melting on the main landing gear
The investigation found that a combination of factors contributed to the
runway overrun. The tail wind and insufficient reduction of engine
power on landing resulted in a longer than normal touchdown on the
runway. The excessive tread wear on all 16 main landing gear tires and
a wet runway resulted in hydroplaning, which reduced effective braking
capability. An incorrect brake line installation further reduced the
aircraft's braking capability, thereby increasing the distance required
to stop the aircraft.
Following the occurrence, the St. John's International Airport Authority
performed texture improvement work on runways 11/29 and 16/34 using
specialized equipment to improve friction.
Volga-Dnepr Airlines is working with Tashkent Aircraft Production
Company to resolve the discrepancy in the brake line installation. The
airline also introduced requirements that flight crews monitor the
heading and wind speed and that a go-around be carried out whenever the
tail wind limitations have been exceeded. It also requires the captain
to decide on using reverse thrust on all 4 engines in special cases.
The TSB is an independent agency that investigates marine, pipeline,
railway and aviation transportation occurrences. Its sole aim is the
advancement of transportation safety. It is not the function of the
Board to assign fault or determine civil or criminal liability.
