Several Factors Led to July 2011 Runway Overrun at the St. John's
GATINEAU, QC, Feb. 13, 2013 /CNW/ - The Transportation Safety Board of Canada
(TSB) today released its investigation report (A11A0035) regarding the 16 July
2011 runway overrun of a Kelowna Flightcraft Boeing 727 cargo aircraft at St.
John's International Airport, Newfoundland and Labrador. There were no
injuries to the three crew members, and damage to the aircraft was minor.
TSB investigators found that the aircraft landed at a higher than normal speed
and almost 2000 feet down the runway. This meant that there was less runway
distance available to stop. A combination of worn tires and a wet runway
caused the aircraft to hydroplane during braking, resulting in a loss of
directional control and the runway overrun.
This accident underscores why the issue of runway overruns is on the TSB
Watchlist and why action is needed to prevent future occurrences. Pilots need
timely reports on runway surface conditions to prepare for safe landings. When
an overrun occurs, longer runway-end safety areas, or engineered systems and
structures designed to stop aircraft, can prevent injuries and aircraft damage.
At the time of the accident, the runway surface-condition reporting standards
did not provide clear direction for rainy conditions or wet runways. The
investigation found that some employees of the airline did not understand the
obligations for reporting incidents under the safety management system
(SMS)—SMS is also on the TSB Watchlist. Although training was provided on
SMS and reporting requirements, there was no specific guidance on what may be
considered a reportable hazard. If all employees do not fully understand their
reporting obligations, some safety issues go unreported, which increases the
risk that those issues might not be identified and mitigated.
Since the accident, Kelowna Flightcraft has improved training for its pilots
on landing distances, braking, wet and contaminated runways, and crosswind
landings. The St. John's International Airport Authority implemented an
expanded runway-friction testing program to gain a better understanding of the
overall condition of their runways when they are wet.
