Safety issue

Safety issue description

Sharp Airlines’ Flight crew operating manual required that:

  • a terminating check be completed if the aircraft was unattended for more than 60 minutes, but did not specify what checks were to be completed on return to the aircraft
  • pitot covers should be installed after the last flight of the day only, where the operator required that they be installed if the aircraft was unattended for longer than 60 minutes. 

In addition, the final visual check, completed by the first officer prior to closing the doors, did not include checking that pitot covers had been removed.
