The pilots of an Air Iceland Dash 8-100 failed to stabilize their approach into Greenland's Nuuk airport before the aircraft made a hard landing, on
March 4, 2011.
The crew had received reports of strong winds, so they made the decision to a 15 degree flap approach, instead of a 35 degree setting, and approach
from a higher altitude, making a steep fast approach.
Once they had visual contact with the runway, they elected to offset their approach to the right of centerline. During approach they received reports
of crosswinds gusting to 42 knots, which exceeds company specs for landing. They then decided to fly a 35 degree flap setting, in spite of already
agreeing to a 15 degree setting, and engaged the flaps at just over 700 feet.
They entered an area of moderate turbulence, and approached the runway from a lateral angle of 25 degrees and began a right turn to line up on the
runway. They were descending at 780 fpm, and were 144 feet over the runway at this point, and were travelling at 115 knots (published airspeed at
this point is 92 knots.
The crew then overshot the centerline on their turn, and touched down on their right main, in a 12 degree bank, descending at 810 fpm, impacting at
3.9Gs. The right main shock strut fuse pin sheared under the impact forces, causing the right main landing gear to collapse. The aircraft slid off
the runway, suffering significant damage to the fuselage, but no injuries to any of the 34 occupants.
Pilots of a de Havilland Canada Dash 8-100 had not stabilised the turboprop's approach to Nuuk in Greenland before the aircraft landed hard and
suffered a main gear collapse.
The aircraft, operated by Air Iceland, had been arriving after a service from Reykjavik on 4 March 2011.
It was attempting an approach to Nuuk's runway 23 in strong winds. Owing to the wind conditions the crew agreed to use a 15° flap setting, rather
than 35°, and fly a steep approach from high altitude.
Having made visual contact with the runway the pilots also opted, crucially, to offset their approach to the right of the runway centreline. The crew
noticed that a stretch of sea leading towards the airport appeared calm, and chose to follow this approach path.
The aircraft (TF-JMB) descended towards the threshold from the right of the centreline. While 3nm out the crew received an automated weather update
which indicated strong variable crosswinds and gusts up to 42kt - under which the operator's procedures prohibited a landing.
