On one-third of the Link Airways Saab 340B flights for which video surveillance was examined, including the occurrence flight, the flight crews did not fit the strap extension between the propeller strap and the airstairs. As the cabin door could not be closed with the strap extension in place, its correct fitment would almost certainly prevent a flight from proceeding with a propeller strap fitted.
Cabin crew checks should reduce the likelihood of the strap extension not being fitted. Flight crew checks should prevent the flight proceeding in the event the strap extension is not fitted and the propeller strap is left on. This action will ultimately reduce the likelihood of a propeller strap not being removed prior to departure.
Link Airways advised that it added the following amendments within the Cabin crew operating manual:
The Flight crew operating manual was amended to include:
Link also enhanced its Line Operational Safety Program, including ground pre- and post- flight inspections, and confirmed training standards.
