An AgustaWestand AW109SP GrandNew ambulance helicopter operated for Derbyshire, Leicestershire & Rutland Air Ambulance sustained a smashed windscreen after a bird strike. The pilot made a safe emergency landing.
The AAIB Final Report was published on 12 August 2021 (see link #1), and the following is the summary from it...
"At about 1,000 ft agl and 140 kt, as the helicopter was descending and turning towards East Midlands Airport on return from a HEMS mission, a bird struck the left windshield. The windshield shattered and the bird entered the cockpit striking the technical crew member (TCM) on the left side of their helmet. The TCM and pilot were unhurt. Debris from the windshield also entered the main rotor disk, making a hole in the trailing edge of one of the rotor blades.
The AgustaWestland AW109 windshield is not designed to withstand bird strikes and the design certification requirements do not require it to do so. Proposed amendments, specifically to the certification of Small Rotorcraft were published in EASA NPA 2021-02 to change this for newly designed rotorcraft. A rule making group is also considering the retrospective application to existing fleets and/or to future production of already type certified rotorcraft".
Carsington Water is a reservoir operated by Severn Trent Water located between Wirksworth and Kniveton in Derbyshire, England. The reservoir takes water from the River Derwent at Ambergate during winter months, pumping up to the reservoir by 10.5-kilometre (6.5 mi) long tunnels and aqueduct.
