What happened
On 12 July 2016, an Air Canada Express flight, operating as GGN7212, was en route from Lethbridge Airport, Alberta, to Calgary International Airport. The aircraft, a Beechcraft 1900D with registration C-GORF, was carrying 15 passengers and 2 crew members.
During the approach into Calgary, the flight crew attempted to deploy the landing gear. Upon selection, the pilots noticed that the nose landing gear failed to provide a gear-safe indication. Following this discovery, the crew entered a holding pattern east of Calgary for approximately one hour while attempting to resolve the mechanical issue. An emergency was subsequently declared. The aircraft completed its landing at 0720 Mountain Daylight Time. The nose gear remained in a partially extended state upon touchdown. There were no injuries and no fire was reported following the incident.
The investigation
The TSB examined the circumstances surrounding the failure of the nose landing gear to lock into the down position. The investigation focused on the mechanical state of the gear assembly and the crew's actions during the emergency period.
