Question to the Department for Transport:

To ask the Secretary of State for Transport, whether Air Safety Support International (ASSI) conducted a formal engine-out take-off performance and obstacle-clearance analysis for departures from John A. Osborne Airport, Montserrat, using a DHC-6 Twin Otter.

It is the responsibility of the individual aircraft operator, in accordance with their operational requirements and based upon the certified performance data, to ensure that the aircraft meet the international aircraft performance standards.

ASSI has undertaken specific aircraft performance calculations for the DHC-6 Twin Otter, associated with engine-out take-off performance (accelerate stop distance), using approved aircraft manufacturers performance data, to review third party operations from John A. Osborne Airport, Montserrat.
