Embraer EMB 170, Dulles, Va., May 30, 2006–Improper servicing of the nose-gear strut and inadequate maintenance caused the failure of the United Express EMB 170 nose gear to extend on landing, said the Safety Board. A factor was the operator’s inadequate checklist.
Dash 8 landing gear incidents
The European Aviation Safety Agency last month determined that the failure of the main landing gear of a Scandinavian Airlines Q400 on October 27 did not result from a design flaw, and that the latest incident bore no direct relationship with the two earlier cases that led to the grounding of the airline’s entire fleet of 74-seat turboprops.
A second incident involving the collapse of a right main landing gear shortly after touchdown on a Bombardier Q400 operated by SAS has prompted an OEM recommendation.
SAS said last month that Bombardier would owe it at least SKr500 million ($77 million) in compensation for the grounding of its Q400 turboprop fleet. Two separate incidents of collapsed landing gear on SAS Q400s prompted Bombardier and Transport Canada on September 12 to call for the grounding of some 85 airplanes worldwide.
SAS has again grounded all 27 of its Bombardier Q400s after the right main landing gear on one of its airplanes failed to fully extend upon landing in Copenhagen on Saturday. Flight SK2867 from Bergen, Norway, carried 40 passengers and four crewmembers, none of whom suffered injuries from the incident.
An Airworthiness Directive issued by Transport Canada yesterday requires a general visual inspection of the left and right main landing gear system and main landing gear retract actuator jam nut on all Bombardier Q400s.
Japanese investigators have determined that
a missing support arm bolt caused the nosegear hatch on an All Nippon Airways Bombardier Q400 to jam as it approached Kochi Airport on March 13, forcing the turboprop twin to land on its nose and prompting authorities to ground all Bombardier
