DORVAL,QC, Aug. 7, 2014 /CNW/ - In its investigation report (A12Q0161)
released today, the Transportation Safety Board of Canada (TSB)
determined that a landing approach below the optimum approach slope at
a low speed and high descent rate led to the hard landing and fuselage
strike of a de Havilland DHC-8-301 at the Gaspé Airport on 10 September
2012. There were no injuries to the 32 passengers and 3 crew members,
but the aircraft sustained significant damage to its rear fuselage.
The Jazz Aviation DHC-8 was on a scheduled flight from
Iles-de-la-Madelaine, Quebec to Gaspé, Quebec. While on its final
approach to land, the aircraft reached the optimum descent angle of 3
degrees and continued its approach, descending gradually below the
slope indicated by the runway's precision approach path indicator
(PAPI) lights. At 170 feet above the runway threshold, the aircraft
descended below the lower limit of the PAPI light descent slope and the
pilot flying reduced power, thus reducing speed and increasing the
descent rate. This indicated an intention to touch down near the runway
threshold. At 45 feet above the runway threshold, the pilot reduced
power to idle, further increasing the descent rate and reducing
airspeed. The nose was raised just prior to touchdown, and the aircraft
landed hard resulting in the lower part of the aft fuselage contacted
the runway surface during the landing.
The investigation found that the pilot monitoring did not realize that
the aircraft was flying too slowly in time to intervene and prevent the
hard landing. An attempt to reduce the rate of descent by applying an
abrupt nose-up attitude was ineffective, as the aircraft was already
flying too slowly. The aft part of the fuselage striking the runway
caused significant structural damage to the aircraft. Furthermore,
the crew had not received training on the manufacturer's recommended
technique to reduce descent rates close to the ground (increasing
engine power and limiting nose-up attitude).
Following the occurrence, Jazz Aviation now provides training on
recovery from high descent rates close to the ground to all DHC-8
pilots, and has made improvements to its operating procedures,
including amending its short-field landing technique and clarifying
stabilized approach and landing criteria.

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.
