What to do
Operators must perform detailed visual inspections of the translating door crank assembly bolts within specified hours or days depending on the aircraft serial number range. If loose bolts are found, corrective actions must be completed before further flight. Additionally, all affected aircraft must undergo a modification of the door crank handles within 8000 flight hours or 48 months to improve bolt retention, which serves as the terminating action for this directive.
Summary
The Airworthiness Directive CF-2014-08R1 is issued by Transport Canada and applies to De Havilland Aircraft of Canada Limited model DHC-8-400, -401, and -402 aeroplanes with serial numbers 4001 through 4530. It addresses the issue of loose bolts in the translating door crank assemblies, which can prevent emergency exits from opening. This directive mandates inspections and modifications to ensure the secure retention of door crank assembly bolts on emergency and reclassified doors.
What changed
This revision expands the scope of inspections to include additional serial numbers and reclassified doors such as the forward baggage door now considered an emergency exit. It replaces the previous requirement of applying Loctite with a new modification to the translating door handles that improves bolt retention. The directive also updates the service bulletins and compliance timelines for inspections and modifications.
Why it matters
Loose bolts in translating door crank assemblies can prevent emergency exits from opening, posing a significant safety risk during evacuations. Compliance with this directive ensures that operators maintain the integrity of emergency exits, thereby enhancing passenger safety and meeting regulatory requirements. Maintenance and compliance teams must address these issues promptly to avoid grounding aircraft and ensure airworthiness.
