- Investigations still ongoing
- Proactive measures to result in highly rigorous inspections
Today, Transport Canada issued an Airworthiness Directive (AD) applicable to Bombardier Q400 turboprop aircraft following two recent incidents of right main landing gear collapse.
Bombardier has been working closely with safety and regulatory authorities to establish a proactive course of action to ensure a high level of safety is maintained. The AD, effective immediately, requires the operators to implement the following corrective actions:
All Q400 aircraft operators must conduct a general visual inspection of the left and right main landing gear system and main landing gear retract actuator jam nut. This applies to all Q400 aircraft.
Furthermore, the AD requires that a detailed visual inspection of the main landing gear retract actuator be immediately conducted on actuators that have accumulated 8,000 or more landings, or been in service for more than four years since new, whichever comes first. Bombardier estimates that this affects approximately 85 Q400 aircraft.
Newer actuators will also be inspected with varying timelines depending on the age of the actuator.
“We understand that this proactive measure will unfortunately inconvenience many of our customers and their passengers. However, safety remains our primary concern. We are working diligently with our customers to ensure the affected aircraft return to revenue service as quickly as possible,” said Steven Ridolfi, President, Bombardier Regional Aircraft.
Bombardier has sent two separate air safety teams to the sites of the two recent incidents to assist in the investigations involving the Q400 aircraft operated by SAS. The first incident occurred at Aalborg, Denmark on September 9, 2007. The second incident occurred on September 12, 2007 at Vilnius, Lithuania.
Bombardier continues to provide its support to the investigations being conducted by the Danish and Canadian regulatory authorities. Until such time as investigations are concluded by the relevant aviation authorities, Bombardier cannot speculate or comment as to the cause of these incidents.
